The machining center performs multi-process (旋回, フライス加工, 掘削, boring, たたく, 等) and multi-face composite processing on prismatic parts through automatic tool change and table indexing. Practice has proved that the composite machining center is indeed beneficial to solve the shortcomings of long delivery time, low resource utilization, more products in process and slow capital turnover of small and medium-sized machinery manufacturing enterprises. Turning and milling combined processing has thus gained more and more common applications in industrial production.

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.).

切削は旋削に大別される, フライス加工, 中心刃ベースの切削 (ドリル、エンドミルの端面切削, 等). これらの切削加工の切削熱は刃先にさまざまな影響を与えます。. 旋削とは連続切削です, 刃先にかかる切削抵抗はほとんど変化しません, 切削熱が刃先に継続的に作用します。; フライス加工は断続的な切削の一種です, 刃先にミーリング力が断続的に作用します。, フライス加工中に振動が発生します. 刃先への熱影響は、切削時の加熱と非切削時の冷却が交互に起こります。, 旋回時よりも受ける熱量が少なくなります。.
