Grinding is an effective and inexpensive means employed in the finishing process. Internal grinding (ID grinding) is a precise means of producing an item for manufacturers. Over the last several decades, even the older machines continue to operate. Accurately, swiftly and reliable, both old and new ID grinders have no productivity equal.
Types of Internal Grinders
Internal grinders are finishing tools employed to produce one of several internal cylindrical surfaces. The results may be grooved, profiled, straight or tapered. To achieve these goals, the operator has to select the right type of internal grinder. In general, a shop can elect to employ any of three basic types of internal grinding machines. These are:
1. Centerless Internal Grinder: Shops employ this type of grinder for producing cylindrical and tapered holes in various bushings, cylindrical liners, and various other cylindrical components.
2. Chucking Type Internal Grinder: This machine can perform both plunge and transverse grinding. The operator usually mounts the workpiece in a chuck – hence its name. Alternatively, he or she may use a magnetic faceplate.
3. Planetary Internal Grinder: If the shop has to work with an irregularly shaped workpiece, it will employ this type of internal grinder. The workpiece does not rotate.
While other types of grinders do exist, these are the most commonly employed type of internal grinders.
Why Use Internal Grinding Machines?
Grinding machines execute the right finish for the internal surfaces of a workpiece. They are an effective method of removing comparatively small amounts of metal swiftly, accurately and effectively. Some modern machines can actually remove high volumes of material quickly. It depends upon the machine and the customer’s specifications.
