Advantages Of Hard Guide Slant Bed CNC Lathe
- Linear rolling guide rail of inclined bed CNC lathe meets the high speed and high-efficiency requirements.
- The lubrication mode adopts the circulating type of uninterrupted oil supply.
- The classic complex rail structure ensures the machine’s stability when cutting with high rigidity.
- Spindle step-less speed regulation, hydraulic chuck, hydraulic tail seat, horizontal eight-station tool rest, closed protection.
- CNC lathe with an inclined bed adopts an integral inclined bed structure. It can maintain the stability of machine accuracy during recutting.
- CNC lathe with an inclined bed adopts complete guide rail protection, and the cooling box and chip remover are separated from the main engine.
- Machine tools have a wide range of processing properties.
- The mass production of complex parts has had a good economic effect.
