Das Bearbeitungszentrum führt mehrere Prozesse durch (drehen, Mahlen, Bohren, langweilig, klopfen, usw.) und mehrseitige Verbundwerkstoffbearbeitung an prismatischen Teilen durch automatischen Werkzeugwechsel und Tischindexierung. Die Praxis hat gezeigt, dass das Bearbeitungszentrum für Verbundwerkstoffe tatsächlich von Vorteil ist, um die Nachteile langer Lieferzeiten zu beheben, geringe Ressourcenauslastung, mehr Produkte in Bearbeitung und langsamer Kapitalumschlag kleiner und mittlerer Maschinenbauunternehmen. Die kombinierte Bearbeitung von Drehen und Fräsen findet daher immer häufiger Anwendung in der industriellen Produktion.

Difficult-to-machine materials are materials with poor turning and milling workability. Performance of this material is greater than or less indicators (HB> 250, σb> 1000 MPa, δ> 30%, αk> 100 MPa, K <41.8 W / mk) one or more, are all difficult to cut materials. It can also be measured by phenomena in the cutting process (cutting force, cutting heat, tool wear and tool durability, processed surface quality and chip control, etc.).

Cutting is roughly divided into turning, Mahlen, and center-tooth-based cutting (end face cutting of drills and end mills, usw.). The cutting heat of these cutting processes has different effects on the cutting edge. Turning is a continuous cutting, the cutting force on the tip does not change significantly, and the cutting heat continuously acts on the cutting edge; Milling is a kind of intermittent cutting, and the milling force is intermittently acting on the tip of the blade, and vibration will occur during milling. The heat effect on the cutting edge is the heating during cutting and the cooling during non-cutting alternately, and the total amount of heat received is less than during turning.
