DVT400 CNC Double-column vertical lathe()
1. This series machine is suitable for machining in industries of motor,turbine, aerospace, mining as well as metallurgy, etc.
2. It can make rough and accurate turning the internal and external cylindrical surface, conical surface, plane,head face,grooving,severance,constant linear cutting, cutting thread,etc.
3. CNC control system of Siemens or Fanuc can be available.
4. Working table adopts hydrostatic guideway.The spindle is to use NN30(Grade D) bearing and able to turn precisely,Bearing capacity of bearing is good.
5. Gear case is to use 40 Cr gear of gear grinding. It has high precision and little noise. Both hydraulic part and electrical equipment are used famous-brand products in China.
6. Plastic coated guide ways are wearable.Centralized lubricating oil supplying is convenient.
7. Foundry technique of lathe is to use lost foam foundry (short for LFF) technique. Cast part has good quality.
8.We can collocate cooling system, escape of chips system and close shield of complete appliance according to consumers\\\\' need.
9.The stepless gear shift lathe has not only functions of turning like common lathe, but also has functions of constant linear cutting and cutting thread.
