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.



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.

Choosing a Spray Gun – A Complete Guide

The intent of this article is to cover all the important things to consider and provide information to help you choose the right spray gun for you.


If you are just getting started in spray application you may be over whelmed by all the variables that are to be considered. From choosing the right coating, to safety considerations when spraying, to choosing the actual spray equipment. If you have been able to wade through the choices you may be at the point that you have decided you will be using a spray gun and want to determine which spray gun will best meet your needs.


Variable 1 – Fluid Viscosity


Viscosity is usually referenced as low, medium or high but if you do not have the viscosity of your coating provided you can also use a measuring device like a Zahn cup which will give you a reading in seconds. You can then use a conversion chart to determine the viscosity of a given coating. Most spray gun manufacturers including Binks and Devilbiss will often list the proper spray gun set up based on the coating viscosity you will spray using a certain cup like for the Trophy Gun the viscosity is listed in seconds in a Zahn 2 Cup. You can also often get a spray gun recommendation on the technical data sheet for your coating. However if you will be spraying a variety of coatings then having a general reference point of the coating type and viscosity of the coating will give you the ability to reference what spray gun setup might be ideal.  In general certain types of spray guns are better suited for heavy viscosity coatings than others.


For high viscosity coatings like zincs, enamels, ceramics, or glues you will typically want to use a conventional spray gun. Or if you need to spray even heavier bodied coatings or need higher production then you will often want to consider an Airless or Air Assist Airless.


For other coatings it will depend on your finish requirements. HVLP will help reduce the coating you use by having higher transfer efficiency. LVMP will allow for similar transfer efficiency to HVLP but may not meet environmental regulations in certain industries, conventional will provide the finest atomization but can use twice as much paint in a given time that HVLP will.


In addition to having implications for the type of gun to choose, viscosity will also be important in determining how fluid is delivered in a spray gun. The three ways to feed paint to a spray gun include pressure, suction, or gravity. Each feed method has its benefits and limitations. In general Gravity feed spray guns will keep waste to a minimum and provide ease of use. However to use a gravity feed spray gun the material must be thin enough to flow easily. Suction feed spray guns will have similar fluid flow requirements to gravity fed spray guns. Suction fed spray guns do offer potential agitators which can be helpful for coatings that require agitation. Suction feed spray guns will require slightly more cleaning. If your coating is highly viscous you will most often need a pressure fed spray gun. Pressure feed spray guns can supply highly viscous coatings easily making them the ideal choice for high viscosity coatings.


Variable 2 – Production Requirements

In addition to a variety of feed methods and air cap styles, high quality spray guns have a variety of set ups available. By offering larger air caps and fluid nozzles you will be able to choose a spray gun that will be able to provide the production level you need or if a spray gun is not fast enough you may want to consider an airless.  You can get an idea of what production you can expect out of various fluid nozzles here. The Air Cap you choose will determine a few important things including the size of the spray pattern and the caps ability to break up heavy viscosity coatings the higher the CFM of the air cap typically the heavier bodied coating it will atomize. BY knowing your production requirement you can be better able to choose the right fluid nozzle and air cap


In addition to choosing the air cap and fluid nozzle the Production requirement will be pertinent in choosing how you feed your spray gun. Pressure pots offer higher volumes of coating which can be ideal if you will be spraying more than a gallon of paint at a time. They also provide greater control over your fluid and air pressures which can help in meeting a production goal. Or if you need the ability to continuously paint you can feed your spray gun from a diaphragm pump or fluid transfer pump. If you will be painting in small quantities and not have coatings with high viscosity then gravity or siphon feed spray gun could be ideal.


Variable 3 – Compressed Air Availability

Different spray equipment will need different amounts of air. A typical spray gun can require 20 CFM of air while an airless can often require significantly more if it is air fed using up to 120 CFM. You can learn more about compressor requirements for spray equipment here.


Variable 4 – Finish Quality Requirements

A final variable to consider is the finish requirements you will need. Spray guns are typically the best appearing finishes. If the coatings are not highly viscous most of the times you can achieve an automotive quality break up of a coating with HVLP, Conventional, or LVMP.


However with heavier bodied coatings you will typically need a conventional gun to get good break up. An air assist airless will provide a finish that is close to a spray gun but not quite the fine finish, they are often used for higher production that requires a quality finish. If you primary need high production or spraying high solids coatings you will typically need an airless.


Variable 5 – Length and Diversity of Use

Spray guns vary greatly in their prices as well as their quality. Higher quality spray guns offer greater variety of air caps, fluid nozzles, and are able to be completely rebuilt. Lower cost spray guns will often not be rebuild able and have limitations on the variety of set ups that are available. You can learn more about spray gun prices and quality differences here.



Choosing the right spray gun for your coating can be a lot to consider. By knowing more about your finish quality, production, compressed air, and viscosity of your paint you will be able to better determine the right spray equipment for you.

How to Use a PEX Crimping Tool

In this article, I’m going to show you the usage of a PEX crimping tool and where to find it.


It is best to rent a PEX crimping tool when installing PEX pipe. This tool is a necessity to perform your task, but it is only used for this reason. This is why it is better to rent than spend your money on a new one that will only more than likely be used this one and only time.


A PEX crimping tool is a tool that is used when you are installing PEX pipe. It is used to create a water tight seal when finishing off your piping project by securing the crimp ring into place on your pipe.
PEX Crimping Tool

How It Works

Installing PEX pipe is not a complicated procedure, but it does take special works and tools to get it done. Obviously the crimp tool is one of those tools that are necessary.


When you have cut your pipe to the size you need it, you will want to slip on crimp rings over the ends of the just cut pipe. Then you will take a fitting, and push it into the tubing. Slide the crimp ring to the edge. Now you are ready to use your PEX crimping tool.


Take out your rented tool and open it. This is done by pulling the handles apart to create an opening. Put the opening of the tool over the crimp ring on one end of the PEX pipe. Make sure it is on well, and then shut the tool by pushing the handles back together. This creates an extreme amount of pressure and forces the crimp ring into place. This then creates a water tight seal, which is obviously something any home owner is seeking when dealing with piping projects.



Only a PEX Crimping Tool

Some home owners have tried to seek out another possible way that the above procedure could be done. One that doesn’t need a PEX crimping tool. Unfortunately in order to replace your old piping with PEX pipe, or even if you are doing new construction, and are starting off with PEX pipe. The only proper, secure, and safe way to get it done is if you have, or have access to a PEX crimp tool.


This is the only tool that creates enough force and pressure at just the right areas to be able to securely smash the crimp ring into where it is supposed to be. Using another tool, or finishing this procedure in any other way can result in a faulty crimp ring, or fitting, causing the pipe to leak, which in turn causes damage to the home.


All home owners know that a leaky pipe is not what they want to wake up to Saturday morning. So, save yourself the trouble and rent a PEX crimping tool. This will ensure that the job is done right the first time, and there will be no long term problems with leaky pipes, and no danger of finishing the project missing some essentials.

Before Buying an Air Impact Wrench What You Should Know

Have there ever been times and instances where you or your family member had to build, construct, or even repair something around your home or office, or even do some work on your car, but you just did not have the right and appropriate tools to get the job done? Do you still use a normal, manual winding wrench to loosen or tighten those loose nuts and bolts?


With the power and science of modern technology nowadays, you, your family members, or even your fellow work-mates need not trouble yourselves with the manual and tedious labor of winding wrenches, for there is the air impact wrench! The air impact wrench is also known as an air wrench, air gun, torque gun, or windy gun.


This automated power tool brings high torque productivity while applying the least amount of effort by the user. This is done by accumulating energy in a rotating collection, then abruptly and rapidly distributing to the output shaft.


There are some points to consider however, when using, and more importantly, buying an air impact wrench. Probably the most touched upon issue and concern when purchasing an air wrench is whether or not the impact wrench you are getting, is the not only suitable to your specific needs, but also for the optimal output of the tool in general.


The best and most effective way to get the best impact wrench possible is by checking the brands and models of these wrenches.


Some other concerns and matters to consider before buying air impact wrenches are:


  • Checking how much torque the air wrench contains
  • The manufacturing and design of the wrench
  • Accumulated and total weight of the wrench itself
  • Air compressor size
  • Size drive of the air wrench
  • Budget to purchase the actual wrench


These points, though seemingly common and surely considered before purchasing the actual air wrench by the prospective consumers, are some of the most essential issues which are overlooked by the buyers themselves. Taking these points into consideration when looking to buy an air wrench will help you to make the right choice.


Buying the best wrench for your needs will undoubtedly save you not only time, or money, but ultimately you will have the satisfaction of having purchased the best tool out there for you. Be sure to keep these tips in mind, and you will definitely and certainly become the proud owner of an air impact wrench that will get the job done.

How to Use a Double Flaring Tool

One of the specialty tools that everybody who does his own auto repair should own is a double flaring tool. With this tool it’s possible to do a professional looking job with brake line or transmission cooling line replacement. Without this tool this is a very difficult job because it’s almost impossible to find the correct length steel line. A double flare is the best sealing and strongest way to flare a tubing end.

Double Flaring Tool FT-10A

Double Flaring Tool FT-10A


  1. Use a tubing cutter and cut the tubing to the desired length. Remove any burrs on the cut end of the tube. Slide the tubing nut on the tube, hex end first.


  1. Loosen the wing nuts and insert the tube in the appropriate opening of the tubing clamp. Place the correct sized adapter upside down beside the protruding end of the tube. Allow the end of the tubing to protrude from the tube to match the thickness of the large part of the adapter. Tighten the wing nuts tightly. Keep the halves of the tool parallel to each other as you tighten.


  1. Turn the adapter over, coat with a small amount of brake fluid and insert into the tube.


  1. Place the flaring tool on the tubing clamp, making sure the screw point is centered on the adapter and the flaring tool is locked on the tubing clamp. Turn the screw clockwise until the adapter bottoms out of the tubing clamp. Final tightening is easier if you clamp the tool in a vise if you have one.


  1. Loosen the screw and remove the adapter. The tubing end should have a bubble look at this point.


  1. Position the flaring tool with the point entering the tubing end and centered. Turn the screw clockwise and tighten until the cone is bottomed out completely.


  1. Remove the flaring tool and inspect the tubing end. The flare should be even all around with no cracks or gaps. Remove the tubing from the clamp.




Always carefully check the new flare for cracks. Do not use if any cracks are found.

How to Use A Pruning Saw

Once you’ve decided you need to make a pruning cut and know that the wood is too thick for the otherwise-preferable use of hand pruners or loppers, it’s time to get out your pruning saw. Pruning saws are your choice for wood about 1.5 inches thick or more and your last resort before the very large stuff that you might only be able to do with a chainsaw. As such, they are used to cut a wide range on the large end of wood thicknesses.


Since saws are used on thick, often long wood, their use often comes with more cautions and considerations than pruners and loppers, which are basically strong and specialized scissors. Saws can require significantly more strength and control.


This guide covers tips and cautions for the use of saws in pruning you can reach from ground level.


Pruning with A Saw, General Technique

Wear sturdy work gloves and possibly safety goggles if you’re in a dense shrub. Choose the exact spot to cut and a healthy cutting angle. As you prune, it may help to consider these steps:


  1. Notice nearby wood you want to preserve. Often you will be working in tight-angled crotches or near other branches you do not want to cut. More than any other pruning tool, saws easily slip and can quickly injure wood unintentionally, so note this risk in your mind.


  1. Choose a comfortable direction of cut. When possible, choose to cut from a top side to a lower side, so gravity is pulling the saw into the wood. By changing where you stand relative to the plant and the angle of your saw, you can usually make the same cut in many different ways to suit your access and comfort.


  1. Reduce limb weight with preliminary cuts. This step is crucial and not anticipated by many gardeners. Thick or long branches have significant weight that will cause a premature break and tear before you can complete a saw cut. This is because your saw cut will reduce the wood holding the limb to a weak, narrow strip. To prevent a tearing wound to the plant, you must tactically remove this weight before even starting your last cut at your chosen spot.


  1. Begin your final cut with a starting groove. Without this groove, the saw will want to slip away from your site. Slipping is especially a risk on non-horizontal branches.


  1. Begin to cut. Working in the groove to guide your strokes, you can cut at a brisk speed now, straight back and forth, keeping in enough control to not slip and wound nearby wood or yourself. Cutting happens on the pull stroke, so bite into the wood on pulling and push back lightly.


  1. Finish the cut. Saw until the branch comes cleanly away from the plant. Occasionally some rough wood will be left at the bottom of your cut, like a splinter beard. To achieve that perfect, baby-smooth cut, you can shave this off with a light stroke of your blade pressed flat against the pruning wound.


Other Tips and Cautions For Pruning Saw Use

  1. Work comfortable. Set your stance a little wide and plant firmly. Take long pull strokes when possible and pull with a lean of your body for major cuts or at least your whole arm, not just at the wrist and elbow. Conserving strength makes mistakes less likely and makes you a happier gardener.


  1. Keep the blade straight. If the blade flexes, you are applying to much pressure when you push it, or you are not pulling straight. Slow down. Apply pressure only on pulls. Get back to a straight, controlled cut and slowly increase your speed.


  1. Working near the ground? When working near the ground with any tool, try to keep the blade from getting into the soil. Sand and pebbles in the soil quickly dull any blade. You’ll have to do this a lot during renovation pruning, which involves making a lot of low cuts into the thick, old wood of prolific shrubs like lilac and beauty bush, for examples.


  1. Wear your saw in a holster on your belt. This is safe and handy and makes you feel pretty tough, too. Another approach by some is to use a folding pruning saw that can be carried in the pocket. I like these much less—they flex at the hinge under stress. The hinge also tends to collect sap or grit and rust.


  1. Clean your saw out before storing it. Tap the tool on dead wood to release most of the sawdust. Wipe sap and sawdust out of the teeth with clean burlap or other sturdy cloth. Storing tools dirty causes them to corrode and lose edge.

A Close Look at the Foldable Pruning Saw


As a keen gardener, your pruning saw will be an integral part of your tool kit. The fact you have found this page means you on the lookout for something a little more compact than a fixed blade pruning saw.


The safety and convenience of a folding hand saw is a big plus. It can be tucked neatly against the body when not in use, and the sharp edges are kept away from other surfaces such as your flesh or the skin and bark of the plants and tree.


Using a Folding Pruning Saw


Your pruning saw will generally be used to cut through branches from between 1/2 inch wide up to about 5 inches. Anything larger and you will want a chainsaw to do the work for you.


The great convenience of the folding pruning saw is the fact you are able to get into tight working areas with relative ease. When working within the matrix of a tree or shrub you will be able to saw in narrow gaps to remove a branch without damaging the others around it.


Blade Type and Material


When buying a folding pruning saw, it is important to think of the types of branches you aim to be cutting. The saws are designed with either a curved or a straight blade, and the common consensus is that curved blades are better for smaller branches while straight blades make easier work of thicker branches.


User Comfort and the Handle


The type of work you will be doing means it is important to consider user comfort. This generally comes from buying a tool that is well-balanced and has a superior designed handle that is easy to grip.


It is important to consider the size of your hand in accordance with the size of the saw. When buying online, where you will not necessarily have had the chance to hold the saw for yourself, search around for user opinion. Previous buyers will often comment if a saw is uncomfortable to use.


Lefty or Righty


The problem of left-handedness is common when it comes to garden hand tools. Folding saws can be susceptible to this due to the fact many will have an operable lock. Depending on the design, the operation of this may be inconvenient for left-handed uses. A control fitted on the top of the saw is generally the best option as this should be convenient for all operators.


You should also consider the fact that you may be wearing garden gloves when using the folding saw. Comfort and overall grip may be impaired as a result, although thin rubber gloves can mitigate any issues.
