Concave and Convex Wheel Axis Grinding
Grinding is a process by which materials are cut and an object is shaped in a specific way by removing material from the original object. In grinding, the object is worked on by a grinding machine and cutting tools such as wheels, disks, and abrasives. One type of grinding process is concave and convex wheel axis grinding.
Concave and convex wheel axis grinding is a process by which components such as shafts, bearing faces, and other objects are ground. This grinding process is sometimes referred to as non-surface grinding. In this process, the cutting surfaces are not just two-dimensional but three-dimensional. The three-dimensional surfaces are generated with the use of a grinding wheel that has concave and convex geometrical shapes.
The use of a concave and convex grinding wheel has many advantages over other grinding processes. The concave and convex geometries allow for precision grinding since the cutting edges can better contact the workpiece surface. This helps to reduce grinding time, improve the quality of the surface finish, and increase the accuracy of the surface finish. Also, as the grinding pressure increases, the contact area of the cutting surface increases, providing more stable cuts.
When using a concave and convex grinding wheel, some parameters must be taken into consideration to ensure that the process is effective and accurate. The first is the cutting speed, measured in surface feet per minute (SFM). The cutting speed depends on the type of workpiece and the material being machined. The second is the feed rate, which is the rate at which the grinding wheel passes over the workpiece. The feed rate is normally expressed in feed per tooth (FPT). Lastly, the depth of cut is the amount of material that is removed from the surface of the workpiece and is typically measured in thousandths of an inch.
Other parameters that must be adjusted for concave and convex wheel axis grinding include the type of lubricant used, the grinding wheel size, the grinding wheel shape and the grinding pressure applied. It is important to select the correct type of lubricant as this can affect the quality of the surface finish and the accuracy of the grinding. If the grinding wheel is too large, then it will take longer to grind the workpiece, while if it is too small it can lead to inaccurate results. The grinding wheel shape must also be correct as an incorrect shape can cause poor surface contact and poor surface finish. Lastly, the grinding pressure applied must be appropriate for the material being worked on. Too low a pressure will result in poor surface finish while too high a pressure can cause excessive wear to the grinding wheel and the workpiece.
By taking the time to adjust the parameters correctly, concave and convex wheel axis grinding can provide the highest quality of surface finish and the most precise grinding results. With the proper parameters, the machining of components for a variety of applications is made possible.
