Characteristic
The headstock, gear-box. apron and bed-ways are made of high quality cast iron, and they are all cast with the resin sand foundry technology. The hardness of induction hardened bed-ways is around HRC 52. The lathe is featured of high efficiency, high precision, high rigidity and excellent cutting performance. The base of the bed is cast into mono block with a chip space. The structure ensures high rigidity of the whole machine and convenient chip disposal. The spindle supported by 3-pointed high-precision bearings and all gears in headstock are precisely grinded, the spindle turns smoothly at high speed. Foot brake, overload protection, chip guard, longitudinal automatic stop device, point-to-point control in spindle, manual lubrication pump, ensures easy operation and good performance of the machine.| Items | Unit | CY-L1630G | CY-L1640G | CY-L1660G |
