Helix milling application
A major focus in milling operations is on reducing the machining time. With specific tool geometries for machining closed, round pockets, it is often possible to eliminate the pre-drilling process. With helix milling, milling paths are programmed with helical entrances that are suitable for pocket dimensions.
Tool overview for the following machining steps:
粗加工
粗加工操作负责大部分的切削加工量。特殊铣削策略，例如高进给加工或摆线铣削，可以减少加工时间，从而提高经济效率。除了带有可转位刀片的刀具和整体硬质合金铣刀外，还使用了具有特殊粗加工几何形状的高性能铣刀。
粗加工剩余材料
粗加工后，在第二个加工步骤中，用户对剩余材料进行加工，特别是在圆角和型腔中，使其加工余量尽可能恒定。通常使用具有圆角的刀具或高进给铣刀。如有必要，球形铣刀也可以去除角落中的残留材料。
半精加工
对尺寸精度和表面质量要求较高时，建议在精加工前进行半精加工。通过半精加工，加工接近最终的形状轮廓。目的是获得尽可能恒定的残余材料，以实现对表面质量要求高的快速精加工。粗加工后的加工余量对于淬硬材料约为 0.5-1 mm，对于软质材料约为 0.03-0.5 mm。在半精加工后，淬硬材料的恒定加工余量为 0.05-0.1 mm，软质材料为 0.1-0.3 mm。
Finishing
The finishing process removes the remaining material in order to achieve the final shape. After pre-finishing, stock removal is 0.05-0.1 mm for hardened materials or 0.1-0.3 mm for soft materials. Ball and/or corner radius milling cutters are the tools of choice, regardless of the final contours of the workpiece.
