Centerless grinding is an ideal machining method that utilizes abrasive rather than solid cutting tools to remove material in a workpiece. The tool is designed to remove the material without touching any of the surface area of the workpiece, which allows the work piece to be quickly ground in the desired thickness. Centerless grinders are designed to use heavy and fast rotating equipment in order to provide a consistent and reliable grind.
With a centerless grinder the worktop or work surface area is completely covered by the grinding tool itself. This enables the grinding wheel to reach deep into the workpiece for its workable areas. Since the worktop area is covered by the grinding tool itself, there is no need to physically touch the workpiece during the process. In this way the possibility of mechanical problems such as excessive chatter, slinging action or even over-speed running is virtually eliminated. Also, since there is no solid surface to rest the work on, the work can be made with any rough or non-grip materials. This results in the unique properties of having a smooth and even top finish with good tolerance to wear and tear.
In addition to providing a smooth finishing touch, centerless grinding machines also allow the user to adjust the cutting speed of the machine along with the distance between the grinding wheel will stop when it reaches a specific depth. This feature is especially valuable when the customer requires specific performance specifications beyond what a general home machine can deliver. For example, many centerless grinders are designed to grind small components in a tight tolerance to prevent chatter while simultaneously providing a high level of precision with exceptional speed and accuracy. In addition, the ability of adjusting speeds and depths in a consistent manner is important when making use of exotic materials and in applications where fine control is required.
Another benefit to using centerless grinders is their flexibility and ease of application. Because there is no edge that can be damaged by the workpiece, the workpieces can be easily and quickly moved from one position to another. Unlike other types of grinders, these versatile machines can be fully mobile and work even when there is no power or electricity available. Many of these machines are designed to work in an environment where multiple electrical and power sources are available and in which the only power source needed is the driver for the motor of the grinding wheel.
One of the most important benefits of the centerless grinder is its ability to provide a consistent and reliable grind. The consistent nature of the output is often a direct result of the consistent force applied to the part. In other words, the user can set the force and amount of force applied to the work piece to precisely define the part quality that will be produced. In addition, the uniformity of the output level eliminates the variation of individual grinding speeds that can lead to inconsistent grind quality. Thus, with the consistent output, the user is able to confidently and successfully conclude the grinding operation.
Centerless grinders may also be used to eliminate the need for traditional feed grinding or chuck grinding. Feed grinders are used primarily to create large quantities of small diameter material that must be ground into a fine powder or paste for use in a wide variety of products. chuck grinders are used to perform similar tasks as feed grinders, except that the end-feed grinders operate at a faster rate than traditional feed grinders. Although they can quickly grind small quantities of material, it is important to note that through-feed grinding machines are not suited for applications where high volume production is needed. Centerless grinders and their associated machines are able to meet these needs very efficiently and with greater accuracy than traditional grinding machines.
