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。在磨削加工中,要注意及时修整砂轮,保持砂轮的锐利,当砂轮钝化后,会在工件表面滑擦、挤压,造成工件表面烧伤,强度降低。
对于一台数控磨床来说，自动对刀系统是一种必不可少的组成部分，因为在装夹完成以后，精密外圆磨床报价,高精度磨床报价，通常都是通过自动对刀系统找到砂轮对工件加工的切入点的精确位置，也就是上一道工序加工好的位置基准。与传统磨床的手动对刀相比较，数控机床自动对刀的精度要高得多，可以达到3微米以内，从而大大减小了工件的磨削余量，使生产工艺更加优化，加工效率得到提升。自动对刀系统的作用还不止于此，通过精确、高效的自动对刀功能，精密外圆磨床报价,数控磨床，对刀系统可以将对刀数据记入机床数控系统进行处理，从而直接进行程序磨削，完成接下来的磨削工序。因此，这一系统被广泛应用在数控床外圆磨床、端面外圆磨床、螺母磨削中心、齿轮磨床及曲轴磨床等各类数控磨床上。 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。在磨削加工中,要注意及时修整砂轮,保持砂轮的锐利,当砂轮钝化后,会在工件表面滑擦、挤压,造成工件表面烧伤,强度降低。

φ500/φ630/φ800 系列数控外圆磨床采用后置移动结构形式，既砂轮架沿头架、尾架主轴中心线平行移动及砂轮架沿头架尾架主轴中

心线成垂直角前后移动；此结构形式减少了采用工作台移动的结构形式时，因工件重量的变化而造成工作台导轨的微量变化，从而影响工

件磨削精度的弊端；具有移动部件质量轻、质量变化小，运动部件惯性小，高效节能等优点。

φ500/φ630/φ800 series CNC Cylindrical Grinding Machine adopts the form of rear moving structure, both the sand wheel frame moves parallel along

the head frame and the tail frame spindle center line and the wheel frame moves forward and backward into the vertical angle along the tail frame spindle

center line. This structure form reduces the variation of the guide rail due to the change of the workpiece weight when the worktable is moved, which affects

the workpiece grinding precision. It has the advantages of light moving parts, small quality change, small inertia of moving parts, high efficiency and energy

saving.
