When Is Ultrasonic Polishing Equipment Justified?

Ultrasonic polishing is ideal and justifiable when work on small to very small details is required.

 

Manual polishing is a very tedious process, and in particular very small intricate detail work requires additional effort and patience. Ultrasonic lapping machines, available now for quite some time, have been improved in recent years to effectively replace certain time-consuming and costly small detail hand finishing work.

 

Ultrasonic Unit Features

By comparison to conventional die profilers, as well as air-powered lapping machines that may have a stroke length of up to ¼ inch, the reciprocating action of an ultrasonic unit ranges only from .00004 to .00012 inches. However, the extremely fast reciprocating tool motion of 21,000 and up to 25,000 strokes per second provides the extra productivity and gives the polisher complete fingertip control when finishing even the most intricate ridges, slots and details.

 

Ultrasonic systems usually consist of an electronic power module (110 or 220 volt) with a slender electric cord that powers the lightweight and easy to manipulate small, ultrasonic handpiece. Commonly, an automatic power feed system in the module adjusts the frequency required to accommodate the various individual abrasive tools that are installed for the finishing process. The systems are equipped with numerous clamps that will accommodate tools ranging from small diamond files to conventional type polishing stones and/or ceramic stones and laps.

 

As with all other power tools, great care and attention should be given when working with ultrasonic machines. Because of the ultra-fast motion, tools that are overly aggressive (especially coarse diamond files, etc.) should never be used. Surfaces that must be flawless can easily be scratched and made wavy or damaged.

 

On the other hand, dense/hard, fine grit ceramic or vitrified abrasive polishing stones or laps made of brass and cast iron when used with premium diamond compound, permit the beginner to acquire a better understanding of the fast cutting powers these ultrasonic systems offer. Note: Only the most experienced operator should use diamond files or diamond stones for ultrasonic polishing.

 

Ultrasonic Applications

We need to stay objective and remind ourselves that ultrasonic polishing is not for everyone. Frequently, ultrasonic systems are perceived to take care of all polishing problems. This is not so. Ultrasonic polishing is not a cure-all for every mold and die shop that does in-house polishing. There are many polishing professionals and/or mold shops—doing mostly mid-size to large work—that may not require an ultrasonic system. In many instances, the units are simply not practical for mid-size to large type work and ultrasonic systems are not recommended to be used on larger details and surfaces exceeding a 3/8-inch square.

 

Nevertheless, ultrasonic finishing has its place in a polishing environment and it is not overstated to say that in some instances the cost of one ultrasonic system may be recouped by polishing three to four multiple cavity/core molds. For instance, an experienced individual, when working with an ultrasonic polishing machine on very small details, may reduce finishing time by as much as 40 percent and up to 65 percent.

 

In the past, there have been several good, but very expensive ultrasonic systems on the market. The name of one system may differ from the other, yet they all practically evolved from one source. However, several new models, which have been recently developed and have proved to be highly effective, as well as very affordable for even the smallest mold shop or polishing house, are now available in the marketplace.

 

Ultrasonic Advantages

Ultrasonic units with super-fast, very short strokes, provide virtual unrestricted fingertip control. By comparison, regular reciprocating tools—such as air-driven or electric flexible shaft-operated die profilers—are more restrictive in movement and less flexible to handle.

 

Nevertheless, die profilers and/or various other filing machines are great for medium to large mold details and when used at a comfortable speed range and proper stroke lengths they will provide excellent finishing capabilities.

 

Ultrasonic polishing is ideal and justifiable when work on small to very small details is required. It is safe to say that the smaller, more intricate or precise the finishing work needs to be, and/or the harder the materials are which require finishing, the more likely it is that an ultrasonic unit will improve polishing time. Subsequently, complicated heat-treated molds and dies, carbide dies or inserts and detailed punches with fine edges and very narrow slots machined by EDM are perfect for using ultrasonic polishing systems.

 

It should be mentioned here that there are other advantages that make certain ultrasonic systems a practical purchase. Meaning, various models offer dual operating capabilities where the electronic power module not only has the ability to drive the ultrasonic handpiece, but also regulate the speed and rotational direction for a variety of rotary and/or reciprocating hand tools. Having these secondary functions presents additional cost savings over single function ultrasonic units as they permit a full range of filing/reciprocating capabilities as well as rotational grinding/polishing using mounted points, burs, polishing brushes and felt bobs. Furthermore, since the rotary or reciprocating hand tools are powered with internal DC motors, the thin electrical cord provides more freedom of movement when compared to flexible shaft powered tools.

 

Summary

When selecting a supplier for this type of equipment it is most prudent to purchase from a respectable company that has been around for many years, offers good customer service and has some experience in ultrasonic polishing, which can be passed on to the customer, even via the telephone.

 

I think Best Diamond Industrial Co., Ltd. will be the most excellent choice. Besdia supplies high quality ultrasonic lapping machine and much more tools for you. Learn more information about Besida, welcome to check out the website here: www.besdia.com

Beginners Guide To The Impact Wrench

If you’ve ever experienced trying to loosen a large, fretted or corroded fixing, then you’ll appreciate what I’m about to say. Often working in tight spaces or at awkward angles, nuts and bolts can be extremely difficult and time consuming to fit or remove. Skinned knuckles, broken tools and jobs taking hours longer than you’d planned, all contribute to the frustration that nuts and bolts cause on a daily basis for people across the world. Even experienced professionals, such as fitters and mechanics, will experience these problems on a regular basis.

 

The solution? Well, there are a number of factors to consider, but the most important is the force you apply to the fixing. Without adequate force, the fixing will either be under tightened (under torqued) or simply won’t come undone. Secondly, and this is particularly important for busy professionals, the time taken to fit or remove a fixing can be painstakingly long if it is in a hard to reach position. Similarly, the time taken up by repetitive jobs, like removing and refitting vehicle wheels, can really add up over the course of a day and eat into your profit margin or your family’s patience.

 

Using an impact wrench solves both these problems. It is capable of delivering a much larger force than you can apply by hand, without additional leverage, and it greatly speeds up the tightening and loosening of fixings, especially those that are hard to reach. So, if you can relate to what I said earlier, you’ll want to read on.

 

What Is An Impact Wrench And How Does It Work?

An impact wrench is used to aid the tightening and loosening of nuts and bolts by reducing the effort required by the user and increasing the speed at which fixings can be tightened or loosened. There are a variety of different types on the market but they all work in fundamentally the same way. Essentially, they apply a rotational force (or torque) in short bursts (or impacts). They are driven by a motor which is powered by air, mains electricity, or battery (usually referred to as a “cordless impact wrench”).

 

Because the force is applied in short bursts, the user is able to apply a much larger torque to the fixing than they would use a regular wrench; sometimes with only one hand. This greatly reduces the effort required by the user, which results in less fatigue and fewer injuries or strains. The time required to complete a task is also reduced meaning that the user can finish the job faster and, in the case of a business, generate greater revenue and profit.

 

Which Type Is Right For Me?

Of the 3 different types of impact wrench, air, electric and cordless, each has its advantages over the others. Originally, only the air impact wrench was available and used mainly by professional and race mechanics to quickly remove and refit wheel nuts (lug nuts). Depending on the model, air tools are powerful, fast and robust making them ideal for use in a professional environment. However, they do require a large volume, high pressure air supply to operate and regular maintenance, which means they aren’t really suitable for infrequent or home use. And, as they’re attached to the compressed air supply by an airline, it can be difficult to move them around a workspace.

 

The corded electric impact wrench is also powerful and fast (again, depending on the model) but is less robust than the equivalent air tool. It too is attached by a cord making it difficult to move around a workspace and, of course, it cannot be used in the absence of a mains electricity supply. However, it can be less expensive than an air or cordless impact wrench, making it an attractive choice for home use.

 

Perhaps the most sought after, particularly in recent years as the technology has improved, and are cordless (battery powered) impact wrenches. The more expensive, higher voltage units deliver performance approaching that of an equivalent air tool but without the additional infrastructure. They are also completely portable and the absence of a cord means they can be moved easily around a workspace and used in hard to access areas. Unfortunately, they are often the most expensive and can be relatively heavy due to the weight of the battery packs.

 

At present, air impact wrenches remain the most popular with professional mechanics. But, as technology continues to improve, the cordless impact wrench will become increasingly popular, less expensive, and ultimately dominate the market.

The Advantages of Shrink Fit Chuck

If you do high speed, or high torque machining you should seriously consider the benefits of shrink fit technology.

 

Heat shrink tooling is considered one of the best methods for high-performance machining. The mold and die industry was the first segment of the manufacturing market to look for more precise tool holder options, due to the need for a slim nose and long reach. Today, every segment of manufacturing can benefit from the advantages of shrink fit tooling.

 

In this article, I’m going to show you the basic introduction to shrink fit chuck.

 

Tool holder Selection

 

When looking for tool holder solutions for any type of machining, it is always good to focus on the three main features that a tool holder must bring you:

 

  1. Rigidity

Rigidity comes from sufficient taper contact and proper clamping of the tool holder in the machine tool spindle.

 

  1. Accuracy

Accuracy comes from minimal run-out at the cutting edge of the cutting tool when clamped in the holder.

 

  1. Balance

Balance comes from a balanced assembly of the tool holder (including all accessories such as pull-studs) and cutting tool combination.

 

You may also often think about the following:

 

  • Geometry of Tool Holder

Geometry is important to avoid collisions with the workpiece. In regards to the EDM process, electrodes must be machined accurately and efficiently. Oftentimes, deep ribs are required in the part process and may present challenges. Also, deep cavities such as large door panel or bumper molds require deep reach with extreme clearances.

 

  • Cleanliness of The Tool Holder

Cleanliness is required to avoid excessive run-out, especially when machining graphite.

 

  • Extending Cutting Tool Life

Since high-end cutting tools are needed to obtain the best performance in the shortest time possible, a tool holder that extends cutting tool life can be advantageous. These cutting tools often have exotic coatings that lend to an expensive price.

 

  • Surface Finish at Higher Speeds and Feeds

Some tool holders are used with lower depth-of-cuts, which translates into better surface finishes. This makes balance even more important to minimize vibration at the cutting edge of the cutting tool. Also, proper chip evacuation provides better finishes.

 

Advantages of Shrink Fit Chuck

 

There are 10 inherent benefits that a good shrink fit chuck can offer:

 

  1. Unsurpassed Accuracy

A properly produced shrink fit chuck should be able to guarantee 0.00012’’ (3 microns) maximum run-out at three times the cutting tool diameter.

 

  1. Availability of Slim Profiles

Shrink fit chucks are available with three-degree draft angles and very slim profiles. They can also be modified to be straight walled, if needed, in order to prevent tool holder collision with the workpiece.

 

  1. Gripping Torque

A shrink fit chuck grips the cutting tool 360 degrees around the shank. This leads to a very high gripping torque that prevents the cutting tool from moving during roughing or finishing operations.

 

  1. Extended Reach Options

Shrink fit chucks can use shrink fit extensions that provide the user with many options with standard products. When machining deep cavities, one can place shrink fit extensions into standard shrink fit chucks, getting unsurpassed tool holder lengths with very little run-out.

 

  1. Balance Repeatability and Balanceable Options

Shrink fit chucks can offer some of the best balance repeatability of any tool holding system on the market, since there are no moving parts. In many cases, if a shop purchases a properly balanced shrink fit chuck with correct accessories (such as pull-studs) and uses good cutting tools without inherent unbalance (such as flats or unequal spacing), then they can often have good balance characteristics for running at high speeds without doing an additional fine-tune balancing.

 

  1. Reduction of Tool Changing Time and Less Tool Holder Accessory Inventory

Nothing beats the tool change time of shrink fit chucks if the process is joined with a capable inductive shrink fit machine. Tool changes can be done in 5 to 10 seconds, and most importantly, consistently. This allows the tool holder assembly to be in the machine making chips more of the time, rather than out of the machine waiting to be changed. Also, a shop needs very little additional tool holder accessory inventory (i.e., collets, nuts, seal disks, etc.). This simplifies the process.

 

  1. Cleanliness of Setup

A shrink fit chuck typically is a sealed system by design. Therefore, the introduction of contaminants in the bore is minimized. If contaminants are introduced to the bore of a tool holder, oftentimes run-out accuracy is compromised.

 

  1. Coolant Options

Shrink fit chucks have convenient methods to deliver coolant down to the cutting edge of the cutting tool. This helps with the proper removal of chips and can also aid in providing better finishes.

 

  1. Consistency of Setup

Shrink fit holders provide the great repeatability from tool holder setup to tool holder setup. This is especially beneficial for those shops running lights out. For example, all tool holder setup operators set the tool holders the same with shrink fit holders. There are no variables—such as over-tightening or under-tightening a collet nut or not cleaning out a chuck sufficiently.

 

  1. Availability of Shrink Chucks

Most of the major tool holder builders in the world now offer shrink fit chucks as a standard.

Tips to Help with Choosing the Right Valve for Your Project

Valves are useful pieces of equipment that help control, limit, and shut off flow in a system. In a garden irrigation system, you could use valves to control when different plants get watered. While it is universally agreed that valves are helpful, choosing the right valve can be frustrating. We hear many customers make statements like these: “So many types exist! Some of them do similar things! I don’t know what types of valves to use!”

 

In this article, we will outline what makes each unique valve. For basic users, the most important thing to remember is that a valve does one of two things: shut off or regulate. Some valves can do either/both, but this is a simple way to think of what you need a valve to do. It could help you in picking the right valve. We will now cover each of the major valve categories.

 

Ball Valves

Ball valves are a good example of a shut off valve. They use a spherical seating to stop or allow flow. The ball has a hole through the center, so fluid can pass through when the handle is turned to the “on” position. When the handle is turned 90 degrees to the “off” position, fluid hits the solid side of the ball and is stopped.

 

Butterfly Valves

Butterfly valves can function as a shut off valve or as a regulatory valve. They can fully shut off flow or be kept partially open, which limits flow. Controlling flow can be extremely helpful if you want to decrease pressure in a system. Fluid passing through a small opening will be restricted, making pressure further down the pipeline lower, depending on how far open the valve is. Butterfly valves can also be used as typical 90-degree turn valves, just switching between “on” and “off” positions.

 

Gate Valves

Gate valves, while usually used as shut off valves, can also function as regulatory valves. They use a “gate” that drops or lifts to control flow. When the valve is open, the gate is stored in the tall upper section of the valve, which is where gate valves get their unique shape. Unlike the previous two valves, gate valves are not a quarter-turn valve. They use a hand wheel to open/close whereas ball and butterfly valves use a lever handle. This makes it easy to keep them partially open and also makes operation of any kind easier.

 

Check Valves

Check valves come in many forms. The primary function of check valves is to prevent backflow. This makes them regulatory valves, as they control flow direction. Check valves are controlled by the fluid in the pipeline instead an operator, which makes them different from the valves we have previously examined. Check valves come in many different forms, but we will just cover the two most common types.

 

Swing check valves are a type of valve that uses a swinging function to prevent backflow in a system. The clear PVC swing check valve to the right has a disc that swings open if fluid is passing through the desired direction. If anything tries to flow backwards, the disc is pushed closed, stopping flow. Swing check valves create minimal pressure drop, as the disc is pushed completely out of the way when in operation.

 

The other major type of check valve is the ball check valve. Ball check valves use a ball or half-ball seating to eliminate backflow. When fluid passes the desired direction, it hits the rounded side and passes around and through. If fluid tries to flow backwards, it hits the concave side of the half-ball, pushing the valve shut. Due to the fact that fluid must flow around and behind the ball to get through, ball check valves produce moderate pressure drop.

 

Diaphragm Valves

Diaphragm valves, while not one of the most common types of valves, are very interesting and serve a specific purpose. They are perfect for limiting pressure in a system, making them regulatory valves. These valves have a flexible diaphragm that lowers toward or rises from a “weir” or “saddle” seating. The effect is that only a limited amount of fluid is allowed to pass through.

 

Choosing the Right Valve

In the end, picking the right valve depends on what you need it to do. No two jobs are the same, so there is no one-size-fits-all valve solution. However, you should now have all the information you need to make an informed decision.

 

NICO VALVES CORP. is a leading industrial valve manufacturer in Taiwan and China. The company offers various valves such as check valve, ball valve, threaded end valve, wafer check valve etc. If you have any questions, try to check out NICO’s website and feel free to send inquiry to them.

Gear Rack and Pinion in Straight Cut and Helical

Tell you some information about precision rack and pinion in this article.

 

Rack and Pinion

 

Rack and Pinion assemblies are utilized to convert rotating movement into linear motion. A gear rack has straight teeth cut into one surface of a square or round section rod with a pinion, which is a small cylindrical gear meshing with the gear rack.

 

There are applications where the gear rack is stationary, while the pinion traverses and others where the pinion rotates on a fixed axis while the gear rack moves. The former is used widely in conveying systems while the latter can be used in extrusion systems and lifting/lowering applications.

 

As a mechanical element to transfer rotary into linear motion, gear racks are often compared to ball screws. There are pros and cons. The advantages of a gear rack are its mechanical simplicity, large load carrying capacity, no limit to the length, etc. One disadvantage though is the backlash. The advantage of a ball screw is the high precision and lower backlash while the shortcomings include the limit in length due to deflection.

 

Types of Gear Rack

Rack and pinion gears are available in two variations:

 

Straight teeth have the tooth axis parallel to the axis of rotation. Straight teeth that run parallel to the axis of the gear.

 

Helical teeth gears provide continuous engagement along the tooth length and are often quieter and more efficient than straight tooth gears and also offer higher loading for same rack width. Helical tooth gears resemble spur gears in the plane of rotation, but include teeth that are twisted along a helical path in the axial direction.

 

Applications of Rack and Pinion

 

Rack and Pinion drives are perfect for a wide range of applications, including axis drives requiring precise positioning & repeatability, travelling gantries & columns, pick & place robots, CNC routers and material handling systems. Heavy load capacities and duty cycles can also be easily handled with these drives. Industries served include Material Handling, Automation, Automotive, Aerospace, Machine Tool and Robotics.

 

JIA CHENG Precision Machinery Co., Ltd. reducer is a worldwide well-known brand. This company also provides high quality couplings, gear row, precision rack, and much more products for customers. If you need more information about planetary reducers and precision racks, try to check out Jia Cheng’s website to obtain further details you need.

Basic Information of Tool Holders and Static Tool Holders

Tool holders (toolholders) are the physical interface between tooling and the machine tool. They come in a multiple of different machine mount styles from the older R8 style to newer HSK or VDI mount.

 

Tool holders have three main parts: the taper, the flange, and the collet pocket. Driven or “live” tooling is powered, while static tool holder is not.

 

  • The taper is the conically-shaped area of the tool holder that enters the spindle during tool changing.
  • The flange is the part of the tool holder to which the automatic tool changer is attached when the tool holder is moved from the tool changer to the spindle.
  • The collet pocket is the area into which the collet is inserted before being secured by various types of collet nuts.

 

Some tool holders shrink-fit around the machine tool or cutting tool and remain firmly in place. Others are optimized to the smallest size possible to allow for maximum clearances during machining.

 

Tool Holder Types

Industrial buyers can find these types of tool holders at some manufacturers:

 

  • Machine arbors are motor-driven shafts that turn machine tools.
  • Blank adapters can be customized for specific applications or machining tasks.
  • Boring heads can hold a variety of cutting tools, but are used mainly with boring bars.
  • Collet chucks use collets of various sizes to hold machine tools.
  • End mill holders are designed to holdend mills during milling operations.
  • Milling or drilling chucks are used to hold various cutting tools during milling or drilling applications.
  • Outer diameter (OD) and inner diameter (ID) tool holders can hold a variety of cutting tools.
  • Shell or face mill adaptors are designed to hold shell or face mills, tools used to cut surfaces.
  • Side cutter holders are designed to hold side cutter tools.
  • Saw blade holders are designed to hold saw blades.
  • Tapping chucks are designed to hold tapping tools for threading operations.

 

Mounting Styles

When selecting tool holders, buyers need to specify a mounting style.

 

  • R8 is used by a majority of Bridgeport machines manufactured after 1965; however, this taper is seldom used with today’s high speed machining (HSM) equipment.

 

  • Morse taper (MT) is available in four common sizes: #1, #2, #3, and #4. Each size has a tapered fit for fast changes.

 

  • National Machine Tool Builders (NMTB) defined the NMTB taper for all CNC milling machines. The standard is 3.5 in. per ft. and can require a drawbar.

 

  • Caterpillar®developed the CAT® mounting style, sometimes called the V-flange, to standardize the tooling for its machines. Designations such as CAT-40, CAT-50 and CAT-60 refer to the NMTB taper size. (Caterpillar and CAT are registered trademarks of Caterpillar, Inc.)

 

  • BT is similar to CAT, but is balanced and symmetrical around the axis of rotation. BT uses the same NMTB body-taper measurement notations but uses a metric pull-stud thread.

 

  • Hollow shank tooling (HSK) is designed to increase grip as spindle speed increases. It does not have a pull stud and is often used with HSM. VDI is designed for quick-change tooling and is available in both dovetail and straight-shank versions.

 

  • Tool holders that use base mount tooling (BMT) and straight shank tooling are also available.

 

Tool Holder Sizes

The projection length of the tool holder is the distance from the gage line (the reference mounting surface) to the end of the tool holder. If specifying a collet pocket is applicable, buyers can choose an ER or TG type.

 

Features and Applications

Tool holders can be coolant-fed or have a coolant-thru flange. Some are optimized to the smallest size possible to allow for maximum clearances during machining. Each tool holder is designed for a specific application and tailored to optimize both machine performance and operational efficiency.

 

Tool Holder Manufacturer

Where to find the excellent tool holder manufacturer? I will say Shin-Yain Industrial Co., Ltd. is the recommendable static tool holder manufacturer. The company is specializing in numerous tool holders, like collet holder, static tool holder, CAT tool holder, BT tool holder etc. all can be found. If you have any interest, try to check out SYIC’s website and send inquiry to them.

How to Choose the Right Oil and Grease for Your Equipment

With the Environmental Protection Agency (EPA) emissions regulations, the use of higher-grade engine oil is mandatory to maintain proper engine performance. A benefit of the newer oils is that they’re compatible for use in earlier engines.

 

There are two characteristics to look for when choosing the right engine oil for your compact equipment: classification and viscosity rating.

 

Oil Classifications

Oil categories for use in diesel engines begin with “C.” The American Petroleum Institute (API) CJ-4 category was introduced in 2006 and was intended for high-speed, four-stroke diesel engines. It was designed to meet 2007 model year on-highway exhaust emission standards, and is uniquely formulated to avoid impacting new diesel engine technology durability.

 

In December 2016, API introduced a new heavy-duty oil engine category: CK-4. The new formulations help protect engines from high-heat, high-load conditions typical in non-road applications. CK-4 oils are backwards compatible with all trucks and non-road equipment that use CJ-4 oils.

 

Always use premium oil that meets or exceeds the API service classification of CK-4 for EPA-compliant engines.

 

Viscosity Matching

It’s important to properly match the viscosity rating of your engine oil to the outside temperatures at your work environment. Always refer to the Operation & Maintenance Manual to determine the weight of oil that is recommended in various conditions.

 

A 10W-30 weight oil is a common factory-fill for many current production machines. It offers top performance in temperatures typically ranging from zero degrees F to 90 degrees F and above. A 15W-40 weight performs well from 25 degrees F to 110 degrees F and above.

 

Synthetic or synthetic-blended oils are formulated with additives that can extend oil change intervals and promote longer engine life. A 5W-40 weight synthetic oil is usually capable of providing protection in harsh conditions as cold as minus 40 degrees F and as hot as 120 degrees F.

 

Hydraulic and Hydrostatic Oils

Hydraulic and hydrostatic oils are formulated to meet the growing demands placed on hydraulic components, and there are several different types of these fluids for various applications:

 

  • High-performance — Typically, a custom blend of high-quality lubricants designed to provide peak flow at subzero temperatures while maintaining stability during periods of high-temperature use.
  • Synthetic — An advanced liquid technology designed to optimize cycle times and productivity, and provide good cold weather fluidity for seasonal changes.

Grease

Many machines require grease as a lubricant in pivot points where pins and bushings are located. The lubrication points need greased at various intervals specified by the machine manufacturer. If used correctly, the right type of grease will help extend the life of components:

 

  • Multi-purpose #2 — Developed for normal applications, it provides lubrication to prevent rust and corrosion and protection under heavy and shock loads.
  • Heavy-duty — Containing moly for better adherence to all surfaces, it offers water resistance, extreme pressure capabilities, pump ability in cold temperatures and good seal compatibility.
  • High-performance — Formulated to provide high-temperature performance in severe operating conditions, it’s intended for lube points with sliding and pivoting movements.
