Abstract: Mirror grinding mainly depends on the precision of the machine tool, cutting and grinding amount and wheel selection and dressing. This paper mainly studies the MG1432 high-precision universal cylindrical grinder, exploring the impact on the workpiece roughness through selection and design of various process parameters in grinding, such as changing work table speed in dressing the grinding wheel and grinding, workpiece linear velocity and excessive feeding. The experimental conditions were: Using resin binder white corundum graphite grinding wheels, workpiece: GCr15 (HRC60); dressing tool: sharp single particle diamond correction pen, and ultimately achieving mirror grinding process results.

Abstract: Dimension error and surface quality have much different between each teeth of gear, moreover directly affect the gear work. After many times grinding, grinding speed and wheel contour of grinding wheel changed. This is primary reason of different between each teeth of grinded gear. Aiming at the problem, it is advanced the method of constant speed grinding and improved the tradition grinding machine structure, optimized the function of the wheel corrector using CNC technology. Machine improved can realize constant speed grinding, moreover can rapidly and accurately trim grinding wheel used complicate surface driving parts grinding. So improve grinding quality and increase grinding efficiency.

Abstract: Diamond Dressing Roller is a new kind of diamond tool for profile dressing of grinding wheel on form grinding. In this paper, internal electroplate method manufacturing process of high precision intricate diamond dressing roller is introduced. The tolerance of profiler precision degree of high precision intricate diamond dressing roller by this manufacturing process is less than 0.005mm.
