Cutting section cutting force in grinding, the unit about 1 x 105 ~ 2 x (105) N/was, it has dozens of times more than the limit strength of materials, has such a big cutting force. It is clearly not caused by the strength of the processed material resistance, but by the grinding process of cutting severe friction caused by the unreasonable to improve the cutting process, reduce the power consumption and to lower the temperature in the grinding zone is of great potential can be dug.
Is through the analysis of the grinding process, grinding wheel on each mill for grinding grain. Usually each abrasive cutting thickness (0.2 ~ 0.02) mu m range, curvature radius, and grits rho is 8 microns, commonly is much greater than the cutting thickness, is in most cases, the metal cutting layer will be squeezed, only not resection, this layer of metal is repeatedly squeezed through a lot of grits and fatigue spalling, so most of the friction in the cutting force. If the grinding grain is sharp, the friction will be greatly reduced, and the sharpness of the grinding grain depends on the hardness and strength of the grinding grain, so improving the hardness and strength of the abrasive is an important direction to improve the grinding condition of the grinding wheel.
Pada saat menajamkan paduan bahan keras, gerabah batu jinjing meningkatkan kondisi gilingan dan friksinya karena daya gilingnya yang tinggi dan intensitasnya yang tajam, sehingga mengurangi suhu daerah penggilingan dan friksinya. Selain itu, tanpa cairan pelumas, koefisien gesekan antara batu king dengan logam sangat rendah sehingga tidak menimbulkan luka bakar.
Saat ini, asah CBN juga telah banyak diterapkan, dengan stabilitas panas yang baik, suhu geraham yang rendah, tingkat kekerasan, intensitas kedua setelah batu king, daya giling yang kecil, mampu mempertajam kualitas permukaan yang lebih tinggi. Selain itu, menggunakan penempelan elastisitas tertentu, seperti karet, resin, dan lain-lain, juga dapat memperbaiki kondisi gilingan ampela. Ketika pengeratan meningkat karena alasan tertentu, penempelan seperti ini dapat membuat butiran asah menghasilkan konsesi elastis tertentu, sehingga membuat kedalaman keris secara otomatis berkurang dan menghindari luka bakar.
