Transform Grinding into a CNC-Based Technology

In the ever-progressing world of manufacturing nothing stays the same. If you are not improving continuously you cannot stay in the game for long. This is true in all progressive mold shops that have embraced the latest in CNC technology and automation into almost all aspects of production. The exception being that row of grinders that could have time-warped from the middle of the last century.

 

Automation in other areas is shining a greater light on the lack of automation in grinding. Every attempt has been made to move as much out of the grinding department as possible. With great strides being made in wire EDM, high-speed machining, and hard turning and milling, the grinding department is being bankrupted, in many cases. Still there is a need for grinding in mold shops. Every shop has a bank of grinders. There will be a row of manual grinders of the usual types and a cluster of automatics. The technology in these machines remains unchanged in its basic function and capability.

 

The purpose of this article is to set forth some steps that can be taken to change the grinding department into a CNC department, which are based on successes seen in a range of mold shops from small to large—but all having a need for precision grinding of mold components.

 

Automatic Surface Grinder Benefits

  • Operator can keep two machines running unattended.
  • Skill level is lower so most CNC operators can do these tasks.
  • Accuracy is provided by machine.
  • Wheel management for faster, simpler set-ups.
  • Develop repeatable processes that are machine-based not operator-based.
  • Core requirements for job are controlled—including wheel offset, auto-dress, simple dimensional inputs into conversations graphical screens and grind.
  • Critical dimensions can be checked on the grinder automatically.

 

Six Steps to Grinding Transformation

The steps a mold shop can take to transform grinding into a CNC-based technology are:

  1. Strategically build around the correct machines.
  2. Must have a committed attitude from management.
  3. Must have a positive attitude for grinder hand to increase productivity through CNC technology.
  4. Plan to cross-train CNC operators to operate CNC surface grinders.
  5. Develop high competency at core grinding tasks like surface, slot and step grinding.
  6. Think outside the box.

 

These simple tasks can be completed through the assistance of a high-precision CNC surface grinder faster and easier than through conventional manual grinding.

Basics of the Liquid Filling Machine

The preferred liquid filling machine in a factory is certain to depend on a variety of factors. It not only has to match the type of liquid and bottle, but should also complement the current budget and future growth. Here are a few things to help identify the right liquid filling machine:

 

Type of Liquids

 

A major consideration with the filling machine relates to the type of products that are being bottled. Liquids can be sticky, thick and semi-fluid in consistency, so it is essential to use a machine that matches. For instance, the thick liquid is best paired with the piston filling machine and the thin liquid goes well with the gravity filling machine. There are some liquids that can satisfactory use the same machine, but it generally benefits to always stick to the specific type of machinery to complement the product.

 

Unique Characteristics

 

There are plenty of liquids that can change consistency or thickness as the local temperature starts to change. Other liquids can feature particulates, such as liquid soaps and salad dressings. Any liquid with a unique characteristic can have an impact on the preferred type of filler. For the thick liquids like spaghetti sauce with pieces of mushrooms or vegetables included it is certain to benefit from a piston machine because it has the wide pathway. Using the wrong machine can soon lead to blockages, which means the problematic and slow filling process.

 

Type of Container or Bottle

 

The type of container or bottle is a further consideration in choosing the preferred piece of machinery. For instance, the clear bottle is often paired with the overflow filler to achieve the consistent fill levels. This gives the most attractive look when placed on the store shelves. Also, the size of the bottle will have an impact on the type of filler nozzle to use.

 

Bottles to Fill Per Hour

 

The level of automation varies with the different filling machines. The machine is built to be fully automated, semi-automatic or a tabletop. The fastest fill option is the automated machines that are significantly faster than the alternatives and require minimal operator interaction once the work is underway. The semi-automatic has a much slower production rate because it is necessary to manually switch on the filling process and clear the filled bottles as required. The preferred liquid filling machine should have the ability to meet the production demands for the size of a particular business.

Best Duck Hunting Waders – How to Stay Warm and Dry on Your Next Big Hunt

For the amount of physical abuse that duck hunters take while out hunting it could be considered an extreme sport. Mud, wind, water and cold are usually experienced in spades on most occasions. Because of these extreme weather conditions it is important to keep yourself warm and comfortable. The most important piece of clothing when trying to stay comfortable and warm is a good pair of quality duck waders so why not get the best duck hunting waders you can?

 

Do I Need Chest Waders or Hip Waders?

First of all, if you will be hunting in all seasons I highly recommend that you purchase one of each. When I am hunting in cold weather or deeper water then I would definitely wear my chest waders to keep me warm and dry. If it is warm and sunny or I’m going to be hunting around shallow streams or creeks, then I would use my hip waders.

 

If I were to purchase just one pair of duck hunting waders I would choose a pair of chest waders. With a chest wader you can always drop the shoulder straps and tie them around your waist when the weather is too warm.

 

If you want the best of the best in waterfowl hunting waders look no further than Pacific Eagle’s. They have engaged in manufacturing of neoprene, hunting and fishing field products for over 25 years. Try to check out Pacific Eagle’s website to find ideal wader hunting you want!

Factors You Must Consider When Purchasing a New VMC

In a typical production machine shop, the processing capabilities required can vary greatly between applications: some value power and torque over rpm, others value spindle speed more than torque or power. To ensure the highest level of productivity in all cases, all of these factors must be evaluated when considering a new investment in a vertical machining center.

 

With numerous different manufacturers of vertical machining centers (VMCs) on the market today, selecting the right VMC for a production environment can be a challenging and stressful endeavor. Each machine is designed and built differently, with unique features and characteristics. The key is determining how each impacts performance.

 

In order to cut through the clutter to find the right solution, manufacturers must first learn how to effectively evaluate machine performance by understanding key differentiating characteristics. Several factors to consider during evaluation are parasitic times, cutting times, thermal control, machine construction and production support features.

 

PARASITIC TIMES

Today the average non-cut, parasitic time of a typical production machine shop consumes approximately 30 percent of the machining process. Part designs continue to grow in complexity, with a higher volume and diversity of closely spaced three-dimensional features. In order to minimize parasitic time and optimize production capabilities, evaluation of axis motion and tool-change technologies are critical in the selection of a production VMC.

 

AXIS MOTION

There are substantial differences in the axis motions of modern VMCs, even when evaluating just the top tier of machine tool manufacturers. We conducted a recent comparison test to evaluate the differences in axis rapid traverse rates of several leading VMCs that demonstrated variations as high as 41 percent. A similar evaluation was given to axis acceleration and deceleration rates, resulting in a 45 percent difference between averaged rates. The Z-axis acceleration and deceleration rates in particular, which are crucial in drilling, pocket milling and tapping operations, resulted in performance variations as high as 75 percent.

 

TOOL-CHANGE TECHNOLOGIES

The second key factor equally as crucial to parasitic time is tool change. When considering a VMC, manufacturers should examine the full tool change time from the moment the spindle stops to leave the work zone to the point at which it returns to the desired position and speed. While spec comparisons between leading VMCs might indicate minimal differences in tool-to-tool time, a true comparison that includes chip-to-chip time reveals variations as high as 18.4 percent.

 

In essence, the differences in axis motion and tool-change performance of production VMCs can have a significant impact on a manufacturer’s profitability.

 

CUTTING TIMES

Alternative to parasitic time is the actual time a vertical machining center spends cutting. With parasitic time consuming 30 percent of the machining process, the remaining 70 percent of the machine process is spent in the cut. Cutting times are generally examined by spindle capability, in which there are three primary factors to evaluate: power, torque and speed.

 

To ensure the highest level of productivity in all applications, manufacturers considering new investments in VMCs must evaluate all factors with equal importance.

 

THERMAL CONTROL

Another key factor to evaluate while selecting a vertical machining center is thermal control. Modern thermal-control technologies have made significant advancements in both the productivity and accuracy of machining centers. Some key thermal-control characteristics to consider are spindle warm-up times, spindle growth and temperatures of linear axes.

 

MACHINE CONSTRUCTION

Additional means for evaluating the accuracy of a vertical machining center would lie in the construction of the machine. Manufacturers should be wary of thin frames, structures with overhangs and unsupported components or motion. Machines with these components can face distortion, deflection, inaccuracy and vibration dampening when machining. Manufacturers should also pay attention to the weight and mass of the machine and how the machine is arranged to provide stiffness, rigidity and ultimately accuracy. If a vertical machining center is not rigid and stiff, the X-, Y- and Z-axis thrust can suffer, resulting in lower positioning accuracy and repeatability.

 

PRODUCTION SUPPORT

The last key factors for manufacturers to evaluate before investing in a vertical machining center are general production support features, which encompass chip and coolant management, ergonomics and ease of operation.

 

THE IDEAL PRODUCTION SOLUTION

By evaluating VMCs based on the factors discussed above, manufacturers can ensure the ideal solution for their production environment. Each key factor holds a tremendous impact on productivity, quality, efficiency and ultimately profitability. No two VMCs uphold the same standards, even among market leading machines. In order for manufacturers to see through the clutter, it’s important to keep in mind the factors that will make the biggest impact on their ability to compete globally.

Lathe Chucks and Accessories – What do I need?

When you purchased your lathe, you might not have known just what you were going to do with it or what options were available. Now that you’re gaining some experience, you’re realizing that all of those different chucks and accessories that were available could be quite beneficial for a variety of purposes. However, sifting through the mountains of different parts, chucks, and accessories can overwhelm even the most experienced and harden lathe professional.

 

What is the Difference between Chucks and Accessories?

The chuck is the part of the machine that turns, providing you the opportunity to shape the product in the precise manner that you want. Different chucks will give you different options and opportunities for working the wood or metal (and yes, or the glass). Especially for metal working lathes, chucks can determine the threading spacing for certain projects, allowing you to create the perfect thread for the parts you’re attempting to create, such as bolts, camshafts, or other projects.

 

Accessories offer a breadth of options that can be added to your lathe or used to help enhance the experience, refine the process, or open doors to new opportunities to create even more exciting products using your lathe.

 

Different Choices for Chucks

Some lathe chucks use an integral thread for mounting it to the machine. These tend to be larger machines and are not likely to be used in a residential setting or by a hobbyist. Most other lathes use a back plate for mounting the chuck, which makes it easier to replace and try different chucks for various applications.

 

You can choose from:

  • 2 Jaw chucks
  • 3 Jaw chucks
  • 4 Jaw chucks
  • 6 Jaw chucks
  • Soft Jaw chucks
  • Independent jaw chucks
  • Combination jaw chucks
  • Drawtube actuated lathe chucks

 

The 2 through 6 jaw chucks are used with scroll type lathes and are manual actuated self-centering.

 

An independent 4 jaw chuck is not self-centering, but the individual jaws can be moved independently from one another. These chucks can be used to work on an irregular shaped part, or you can use it to set a piece off center for whatever reason that you would have in doing so.

 

Combination jaw chucks combine the self-centering action of the scroll chuck with independently moving jaws. This adds more flexibility with the ability to have the self-centering benefits. Drawtube actuated lathe chucks are powered using hydraulic or air cylinders to move the drawtube forward or backward. When the drawtube moves, it clamps or unclamps the jaws.

 

Each different type of lathe chucks can perform a wide range of tasks, opening the possibilities of incredible designs and processes. Many of the chucks mentioned here are more than the average beginner lathe worker will need or be able to get the most out of, but each one can be used in many standard lathe machines. The only drawback is that not all of these different types of lathes are available for mini or micro lathes.

Why Do Engineers Use Stainless Steel Ball Valves?

As time goes on engineers continue to develop new technology improving operation services for a variety of businesses in a wide array of sectors. The form of the stainless steel ball valve is no different. It has altered in shape and has been modified to achieve maximum results over the years. It is a reflection of the technological advances that have been made by engineers today.

 

A steel ball valve is located inside a tube and enables waste fluids to travel through a passageway. The valve works by placing an existing hole in the steel ball then the placement of the ball is what controls the function of this valve. Once the holes are proceeding in the same direction as that of the passageways the valve stays open. The fluid begins to stream out in an uninterrupted manner. This is vital to the function of the contraption because if the holes are not lined up correctly then the valve closes and the fluid remains encased.

 

Why Stainless Steel?

 

To effectively execute its function, the valve needs to be strong and untainted when exposed to extreme temperatures and pressures. Sometimes the metal valves connect joints that carry a maximum of 200 degrees. Thus, it needs to handle working under such circumstances without dissolving or bowing. Engineers found this metal to fulfill all of these requirements and then some.

 

It also comes in different sizes and shapes. This is for you to find the exact valve size you need for your operations.

 

Also, these are able to come in two designs, sanitary or industrial. The sanitary ones are designed for the pharmaceutical, cosmetic, food, dairy and beverage industries. When you are looking to purchase one of these specify what industry you need the device for. This way you are guided towards equipment suitable to match your business needs.

 

In daily life, some recognizable valves are used in tap water, plumbing, dishwashers and hot water systems. It is easy to comprehend its mechanical function and purpose if you think about how veins and the heart work inside our own bodies.

 

Veins act as a valve permitting the flow of blood to the heart while maintaining a steady, correct pace. If you choose the right stainless steel ball valves for your business then it should act in the same manner.

 

Think about what type of business you are using the equipment for and narrow in on the products recommended, required by law and what material outlasts the rest.

 

Golden Highope Industrial Inc. Ltd. has specialized in manufacturing stainless steel ball valves since 1990, with years of experiences we provide only high quality ball valves to clients. Here we offer more various specification stainless steel valves for you to choose.

Selecting for The Best Road Cranksets

Cranks are the crucial levers that turn pedal pressure into propulsion and upgrading this transmission keystone is always a cosmetic and performance temptation. But what do you need to know to arm yourself with the right road crankset – cranks, axle, spider and chainrings – for your bike and riding?

 

Before you even start thinking about budget or clever design, you need to check which ones will fit your bike. Even though we tried to limit the axle types on test as much as possible, the sheer number of bikes we had to rope into our testing regime to find a home for all the different variants shows it’s no simple task. Even on same diameter axles, different details mean that different brands often need their own specific bearings to work. Adaptors and converters have made things easier recently but different bearing sizes and fitting standards are still a potential minefield so it’s still essential that you double check your chosen crankset will fit your frame before you part with any cash.

 

Don’t assume that bigger axled cranks are stiffer, either. Overall stiffness is governed by the entire structure, from the chainrings, through the spider and crank then across the axle to the offside crank. While they look fancy, don’t assume that carbon cranks are automatically stiffer than alloy ones either, as both materials use a range of manufacturing methods for a wide spread of results.

 

Don’t get hung up on weight either – cranksets sit in the most central, lowest point of your bike possible. This makes their weight the least obvious of any component in dynamic or handling terms, and it’s why most pro bikes use torque meters or even extra heavy axles to bulk their weight up to the minimum legal lever. Conversely, a lightweight crank that flexes so much it feels like your feet are bending under your bike is really demoralising when you’re trying to claw your way up a climb.

 

Key crankset components

 

Crank length: Cranks – the ‘arms’ – come in different lengths to match different length legs and leverage preferences. The average is 172.5mm but 170 and 175mm cranks are relatively common on complete smaller and larger bikes respectively, and you can get as short as 160mm or as long as 180mm.

 

Axle: Most road cranksets use an axle permanently fixed to the driveside crank and a left crank that bolts/clamps into place. Some brands still use a separate axle, while Campagnolo uses two half axles that join in the centre on its Ultra Torque designs. Most come with 24mm steel axles or 30mm alloy ones.

 

Spider: The four or five-arm piece that connects chainrings to axle. Some are moulded into the arms, some made separately but permanently attached, others are removable. Standard (53/39) chainrings generally have a 130mm bolt circle diameter (BCD – the fitting pattern for the rings), compact (50/34) 110mm.

 

Chainrings: Most chainrings are made from a single-piece reinforced disc with teeth cut into the edge. In many cases brands are interchangeable or replaceable with aftermarket options. Shimano’s ‘blended’ chainring/spider design demands specific replacements to keep aesthetic and functional form.

 

Material: Solid forged alloy cranks are the cheapest option but generally the heaviest. Drilled or hollow moulded alloy cranks then follow in the fashion (but not necessarily function) hierarchy. Carbon wraps on alloy armatures look good but don’t always perform well and even ‘full’ carbon cranks have to use alloy pedal and axle interfaces.

 

Bearings: As well as different axle diameters, different bearing shoulder dimensions mean most cranks will only run in bearings from the same brand or specific aftermarket options, though converters are reducing the number of ‘impossible’ combinations. None of our test cranks obviously lost spin smoothness during our test period.
