Grinding process is a relatively mature tool preparation and finishing methods. Precision grinding tool used mainly fine diamond grinding wheel, to achieve efficient high-speed steel and carbide-forming material. Highlights of this process is: To prevent small diameter tool breakage, should reasonably determine when sharpening grinding pressure. By applying vibration grinding wheel, the grinding force can be significantly reduced, and forming the smallest diameter.

     Precision fine grinding process to some extent, prepared to meet the requirements of the fine cutting tool, but by the grinding force, the minimum diameter of the tool can be stably obtained is limited by. In addition, the grinding process is likely to cause the tool surface scratches and edge defects, will directly affect the level of surface quality and accuracy; grinding heat stress tends to cause changes in the microstructure of the tool surface; concentricity and fine milling cutter diameter deviation, etc. manufacturing error may be greater than the fine cutting of single tooth feed, forming accuracy to be improved.
