金刚石刀具研磨时磨盘刃磨方向与刀刃之间的夹角对刀具刃磨质量影响很大。国内大多数厂家一般都取研磨方向与刀刃呈垂直方向的逆磨方式，实验证明，这是不尽合理的。一、研磨方向与刀刃垂直的缺卢、1．研磨方向与刀刃垂直，则磨盘上的金刚石粉颗粒及各种盘面缺陷（如盘面高点） Grinding disc grinding tool diamond grinding wheel angle between the direction of the angle between the knife grinding quality greatly affected. Most domestic manufacturers generally take the grinding direction and the vertical direction of the knife against the grinding method, the experiment proved that this is not reasonable. First, the grinding direction and the blade is missing, 1. Grinding direction perpendicular to the blade, then the disc on the diamond powder particles and a variety of disc defects (such as disk surface high point)
