对研磨速滑刀过程中影响刀刃角度不成90°的相关因素进行分析。认为磨具的不平度、磨具研磨角不成90°造成两刀弧被研磨点的高度差、两冰刀弧横向不等高、刀片侧面不铅垂,是导致磨具研磨工作面与刀片侧面不垂直的主要原因,也是造成研磨后刀刃角度不成90°的根本症结所在。 The factors that affect the angle of the blade during the grinding of the speed slider are analyzed. That abrasive roughness, abrasive grinding angle is not 90 ° caused by two knife arc is the height difference between the grinding point, two ice knife arc horizontal unequal height, the blade side is not vertical, is caused by abrasive grinding face and the blade side is not Vertical main reason is also caused by the grinding angle of the knife does not form the fundamental problem of 90 °.
