    銑床銑出來的工件為什么不平

    時間:2020-08-26 21:53 點擊次數:

    主要原因是銑床幾何精度誤差和機床剛性不足。

    1銑床幾何精度:

    在加工工件的兩個移動方向上,機床的坐標軸的軸線運動的直線度誤差;

    主軸軸線和加工工件的兩個移動方向軸線專運動的垂直度誤差;

    主軸軸向竄動和主軸錐孔的徑向跳動誤差。

    2機床剛度:

    機床剛性不足。在用大刀盤加工平面時,由于切削力和主軸扭矩的增大,使得機床變形加大,導致主軸軸線與加工工件的兩個移動方向軸線運動的垂直度誤差增加;

    3其他因素:

    銑床工件裝夾不可靠,大刀盤加工時工件竄動屬、振動;

    工件本身剛剛不足,大刀盤加工時工件讓刀、振動;

    加工刀具剛性不足或者裝夾不牢固,大刀盤加工時刀具竄動、讓刀;

    上述所有因素均能使銑床加工的零件的平面度超差。

     

     

    The main reason is the geometric accuracy error of milling machine and the lack of rigidity of machine tool.

    1. Geometric accuracy of milling machine:

    The straightness error of the axis movement of the coordinate axis of the machine tool in the two moving directions of the workpiece;

    The Perpendicularity Error of the special movement of the axis of the spindle and the two moving directions of the workpiece;

    The axial movement of the spindle and the radial runout error of the taper hole of the spindle.

    2. Machine tool stiffness:

    The rigidity of the machine tool is insufficient. When machining a plane with a large cutter head, the deformation of the machine tool increases due to the increase of cutting force and spindle torque, resulting in an increase in the perpendicularity error between the spindle axis and the axis in the two moving directions of the workpiece;

    3 other factors:

    The workpiece clamping of milling machine is not reliable, and the workpiece movement and vibration during machining with large cutter head are belong to and vibration;

    The workpiece itself is just insufficient, and the workpiece gives way to the cutter and vibrates when machining the large cutter head;

    The rigidity of the cutting tool is insufficient or the clamping is not firm, and the cutter moves and gives way to the cutter during the large cutter head processing;

    All the above factors can make the flatness of parts processed by milling machine out of tolerance.
