Machining 3D surfaces
In the die & mould sector, the manufacture of increasingly complex forms is part of everyday life. Continuous further developments in machine tools and CAM software raise performance and productivity to an ever higher level. The tools used must therefore always be state-of-the-art. To achieve optimum results, each design starts with a process analysis.
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。
Pre-finishing
If there are high demands on dimensional accuracy and surface finish, semi-finishing is recommended before finishing. With pre-finishing, machining approaches the final mould profile. The aim is to obtain a residual material that is as constant as possible in order to enable fast finishing with high demands on the surface quality. The stock removal after roughing is approx. 0.5-1 mm for hardened materials and 0.03-0.5 mm for soft materials. After pre-finishing, the constant stock removal is 0.05-0.1 mm for hardened materials or 0.1-0.3 mm for soft materials.
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.
Residual material finishing
The increasingly complex properties of the shapes to be produced require milling of the residual material after finishing, mainly in the corners. Solid carbide ball cutters are usually used for this.
