Technological Parameters of Belt Grinding Process of Hard Steel

Abstract

A mechanical workpiece in the field of the automobile industry (crankshaft, camshaft, valves, gear, synchronizer gearbox ... etc) is good quality, if it fulfills the function for which, it is destined. To ensure the required function of these workpieces, they are necessary for the purpose of machining a high precision superfinishing process. There are several methods of superfinishing in this area, for example: honing, polishing, belt grinding ... etc. The belt grinding is a mechanical manufacturing process by removing of material involving a tool called abrasive belt. It is complementary to the hard turning and recent compared to other process principle and objective. To date the cutting mechanism and its exact effect on the surface integrity remains unclear. This study allows optimizing the technological parameters, such as time of belt grinding, size of the abrasive grains, the rotation speed and lubrication, and seeing the influence of these parameters on the surface state of the hard steel
