Brief introduction :
1. This series machine is suitable for machining in industries of motor,turbine, aerospace, mining as well as metallurgy, etc.
2. It can process external column face,circular conical surface, head face, shotted,severance of car wheel lathe.
3. Working table is to adopt hydrostatic guideway. The spindle is to use NN30( Grade D) bearing and able to turn precisely,Bearing capacity of bearing is good.
4. 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.
5. Plastic coated guide ways are wearable.Centralized lubricating oil supplying is convenient.
6. Foundry technique of lathe is to use lost foam foundry (short for LFF) technique. Cast part has good quality.
