1、合理选择和修整砂轮 Select and repair the wheel properly 采用白刚玉的砂轮较好，它的性能硬而脆，且易产生新的切削刃，因此切削力小，磨削热较小，在粒度上使用中等粒度，如46～60目较好，在砂轮硬度上采用中软和软(ZR1、ZR2和R1、R2)，即粗粒度、低硬度的砂轮，自励性好可降低切削热。 精磨时选择适当的砂轮十分重要，针对模具钢材的高钒高钼状况，选用GD单晶刚玉砂轮比较适合，当加工硬质合金、淬火硬度高的材料时，优先采用有机粘结剂的金刚石砂轮，有机粘结剂砂轮自磨性好，磨出的工件粗糙度可达Ra0.2μm，近年来，随着新材料的应用，CBN(立方氮化硼)砂轮显示出十分好的加工效果，在数控成型磨床、坐标磨床、CNC内外圆磨床上精加工，效果优于其它种类砂轮。 Use white corundum grinding wheel is better, it is the performance of hard and brittle, and easy to produce the new cutting edge, so the cutting force is small, the grinding heat is small, use medium granularity on granularity, such as 46 ~ 60 mesh is better, on the grinding wheel hardness by using soft and soft (ZR1, ZR2 and R1, R2), namely, coarse granularity, low hardness of the grinding wheel, good self excitation can reduce heat cutting. Of selecting the appropriate fine grinding wheel is very important, in view of the condition of the die steel with high vanadium high molybdenum, choose GD is suitable for single crystal corundum grinding wheel, when processing hard alloy, high quenching hardness of materials, the priority of using organic binder diamond grinding wheel, the organic binder grinding wheel grinding, grinding the workpiece roughness of Ra0.2 mu m, in recent years, with the application of new materials, CBN (cubic boron nitride) grinding wheel shows very good processing effect, both inside and outside the CNC forming grinder, jig grinding machine, CNC grinding machine on the finish machining, grinding wheel is better than other species. 2、合理使用冷却润滑液 Use cooling lubricant reasonably 发挥冷却、洗涤、润滑的三大作用，保持冷却润滑清洁，从而控制磨削热在允许范围内，以防止工件热变形。改善磨削时的冷却条件，如采用浸油砂轮或内冷却砂轮等措施。将切削液引入砂轮的中心，切削液可直接进入磨削区，发挥有效的冷却作用，防止工件表面烧伤。 The three functions of cooling, washing and lubrication are used to keep the cooling and lubrication clean, so as to prevent the heat distortion of the workpiece. To improve the cooling conditions of grinding, such as using oil sands or inner cooling wheels. The cutting fluid is introduced into the center of the grinding wheel, and the cutting fluid can go directly into the grinding area and play an effective cooling role to prevent the surface burn of the workpiece.
