  beplay全站app安卓加工即指成型和制坯工具的加工,此外还包括剪切模和模切beplay全站app安卓,在beplay全站app安卓加工的时候,有时候会出现缺陷,下面小编就来说一下减少beplay全站app安卓加工缺陷的几小方法。
  Mold processing refers to the processing of forming and blank making tools. In addition, it also includes shear mold and die-cutting mold. When the mold is processed, sometimes there will be defects. The following small series is about several small methods to reduce mold processing defects.
  一:合理使用冷却润滑液,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,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。
  1: Reasonable use of cooling and lubricating fluid, play the three major roles of cooling, washing and lubrication, keep the cooling and lubrication clean, so as to control the grinding heat within the allowable range, so as to prevent the thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as using oil immersed grinding wheel or internal cooling grinding wheel. When the cutting fluid is introduced into the center of the grinding wheel, the cutting fluid can directly enter into the grinding area to play an effective cooling role and prevent the surface burn of the workpiece.

  二:合理选择磨削用量,采用径向进给量较小的精磨方法甚至精细磨削。如适当减少径向进给量及砂轮速度、增大轴向进给量,使砂轮与工件接触面积减少,散热条件得到改善,从而有效地控制表层温度的提高。
  2: In order to select the grinding parameters reasonably, the fine grinding method with smaller radial feed rate and even fine grinding is adopted. If the radial feed rate and grinding wheel speed are properly reduced and the axial feed rate is increased, the contact area between the grinding wheel and the workpiece is reduced, and the heat dissipation condition is improved, so as to effectively control the increase of surface temperature.
  三:合理选择和修整砂轮,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。
  3: Reasonable selection and dressing of grinding wheel, white corundum grinding wheel is better, its performance is hard and brittle, and easy to produce new cutting edge, therefore, the cutting force is small, grinding heat is small, medium grain size is better, such as 46-60 mesh is better, in the wheel hardness, medium soft and soft (ZR1, Zr2 and R1, R2), that is, coarse-grained, low hardness grinding wheel, good self excitation, can reduce cutting heat.
  以上是关于减少beplay全站app安卓加工缺陷的三方法的介绍,希望能够帮到大家!
  The above is about reducing the mold processing defects of the three methods, I hope to help you!
