Customized Configuration
1.Numerical control coefficient use: SIEMENS, FANVC, MITSUBISHI E60 or native GD980, Huazhong, KND100 controllers and servomotors, programming in ISO International Code, Keyboard Manual Data input with power cut-off protection and automaticdiagnosis functions.
2.Cutting in length and breadth by SIEMES, FANVC, MITSUBISHI E60 or native servo motors, precision ball lead screws.
3.Spindles are frequency conversion with limitless speed changes; transducers adopt Japanese TOSHIBA and native INOVANCEproducts, and spindles adopt Japanese NACHI, NSK and native Harbin for contacting transducers in exact angles featured withhigher rotate speed, better steel quality, and less noise.
4.Either vertical or horizontal 4 station or 6 station tool post can be selected. The post is located on precision contritegears with a high repeated positioning uracy.
5.Chucking appliances are equipped with Japanese HOWA or Taiwanese middle-hollow hydraulic chuck, vacuum chuck and huck, installing Germany 5C collets and Taiwanese hydraulic tail frames. Gas powered or manual tailstock is available.
6.The lathe bed structure is reasonable designed with strong steel quality and good anti-knocking quality. ic brakingdevice is provided for spindle stopping, which is safe and reliable. The bed saddles adopt sticky PVF featured with longlifespan and high precision.
