Lavorazione di pareti sottili e nervature

Gli stampi per iniezione plastica e pressofusione presentano spesso nervature e pareti sottili. Ad esempio, le nervature vengono sottoposte sempre più spesso a fresatura, poiché questo processo è più conveniente rispetto all’EDM (elettroerosione a scintilla). Generalmente, si utilizzano utensili in metallo duro lunghi o estremamente lunghi con diametri piccoli. Inoltre, è possibile ricorrere a soluzioni su misura per il cliente (RibCutter) che si adattano alla rispettiva forma della nervatura.

以下加工步骤的刀具概览:
  1. 粗加工
  2. 精加工

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。

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.
