Bearbeitung von geschlossenen Taschen

Die Herstellung geschlossener Taschen erfolgt meist durch Schruppen in Z-Ebenen. Häufig wird hierbei beim Fräsen der Bearbeitungseintritt über eine Rampe gewählt. Die Wahl des Werkzeuges hängt von der Tiefe der Wände und der zu erzeugenden Ausformschräge am Bauteil ab. Das breite Portfolio von MAPAL mit modularen Systemen deckt auch die Bearbeitung tiefer Taschen mit großen Durchmessern ab.
An einem gerenderten Beispielbauteil ist eine Bearbeitung hervorgehoben.

Schruppen

Die Schruppoperation ist für den Großteil des Zerspanungsvolumens verantwortlich. Spezielle Frässtrategien wie die Hochvorschubbearbeitung oder das trochoide Fräsen können die Bearbeitungszeit reduzieren und somit die Wirtschaftlichkeit steigern. Neben Werkzeugen mit Wendeschneidplatten und Vollhartmetallfräsern kommen Hochleistungsfräser mit spezieller Schruppgeometrie zum Einsatz.

Residual material roughing

After roughing, in a second machining step, users machine the residual material, especially in corners and cavities, removing material as constantly as possible. Usually tools with corner radius or high-feed milling cutters are used. In some cases a ball cutter can be used to remove the residual material in corners.

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.
