问:砂轮进刀时刻度不准,磨削时突然增大尺寸或减小尺寸是何原因? 孔禄初答:(1)应按照规定使用压力油,时值夏日用10号机油代替20号液压油,油质粘度不足(应为运动粘度18.8×10~(-6)～22.2×10~(-6)m~2/s),形成辅助压力油压低,使闸缸作用降低形成进刀刻度不准。建议:先调整辅助压力油压,使之升高,再考虑严格按标准油使用。 (2)如果前罩上(即手轮前罩)无定位销钉或螺母松动,亦能造成进刀刻度不准。建议:检查前罩螺钉紧固否?销
Q: Grinding wheel infeed when the scale is not allowed, when the grinding suddenly increase the size or reduce the size of what is the reason? Kong Lu first answer: (1) should be used in accordance with the provisions of pressure oil, when the summer oil instead of 10 (Hydraulic viscosity 18.8 × 10 -6 ~ 22.2 × 10 -6 m 2 / s), the formation of auxiliary pressure low pressure, so that the role of the brake cylinder to reduce the formation of Intake scale is not allowed. Recommendation: first adjust the auxiliary pressure oil pressure, so that increased, and then consider the strict use of standard oil. (2) If the front cover (that is, the front wheel cover) no pin or nut loose positioning, can also cause the infeed calibration is not allowed. Recommendation: Check the front cover screw fastening?
