The Benefits of Centerless Grinder Setups
Centerless grinder is a popular machining method that uses rough abrasive material in its operation to remove material from a working piece. In the majority of applications, the rough abrasive material utilized in Centerless grinding is carbon fiber or high carbon polyethylene (HCPE). The main benefit of using this grinding method is the use of a minimum number of passes over the workpiece while providing higher accuracy and consistent result. However, with the utilization of numerous passes over the workpiece, it causes stress on the workpiece edges which could cause failure in the long term. Stress crack formation is often observed after long-term use of centerless grinders.
There are two major types of grinders – in-feed and roundfeed grinders. The major difference between these two types of grinder is the position of the workers. In-feed grinders rest on top of the workpiece while rounded grinders rest directly behind the workers. When determining the appropriate model for your applications, it is important to consider the impact of each of these types of grinder on the working piece.
In general, an in-feed grinding wheel requires a two-handle operation whereas rounded grinding wheels use a one-handle operation. The in-feed grinding wheel usually has a smaller deck size than its rounded counterpart. This means that the in-feed centerless grinder requires a greater amount of space than its rounded counterpart. With this additional space requirement, it is likely that the in-feed grinding wheel will cost more than a comparable rounded unit. Although most centerless grinders have similar dimensions, they are made from different materials and the center of the wheel may contain a larger or smaller number of teeth.
Another difference of centerless grinding wheels is the amount of magnetic force that is generated during the grinding process. Most of the machines utilize a continuous magnetic field that is generated within the machine during the grinding process. Some machines utilize a single-arm and single-wheel model which requires more force to complete the grinding process. Some machines are able to use both arms and single wheels simultaneously.
For small to mid-sized work pieces, the in-feed centerless grinding machine is ideal. These machines are capable of grinding small to medium-size workpieces with relative ease. With this feature, the small to medium-sized machining workpieces can be easily and quickly machined without having to sacrifice accuracy and efficiency.
If your machine setup requires a diamond wheel, there are several factors you should take into consideration. It is important that you consider the size of your production area. The size of the diamond wheel and how much the machine can physically handle should also be considered. The last consideration when determining your diamond centerless grinder setup is the availability of your machine.
