Main transmission adopts SRD or servo system, wide range of step-less speed change of table's movement satisfies the requirements of planning/milling/grinding at different speed, independent spindle feeding box enables more balanced feeding to process plane/inclined plane/T slot/combined guide-way/rack, etc.
1. More stable table movement.
2.To get enough lubrication of table at any speed with independent lubrication system.
3.The adoption of heat-treatment techniques like drawing the temper off/quiver-ageing/hyperacoustic quenching on key parts as the machine body/column enables more stable accuracy and longer working life.
4.Machine body/column/beam/table are designed according to the parameters of heavy-duty machines, and the material is cast iron (≥HT250),so the machine is with better stability & accuracy retentivity.
