Product Feature

The machine could process different inner bore, circular conical surface and screw thread by numerical control system, especially suitable for the small and middle size shaft and plate workpiece from rough processing to finish processing in batch. It has advantages like higher automation, simply programming and higher accuracy.

This series of machine tools is a mature product mainly exported, with compact structure, beautiful appearance, large spindle torque, high rigidity, stable and reliable performance, and excellent precision retention.

Adopt high-precision spindle bearing set and the spindle with precision assembly and dynamic balance test to ensure the spindle with high precision, low noise and strong rigidity.

Foundation

Firmness of foundation effects directly basic accuracy of machine tool, so the foundation should meet below requirements:

a) In order to eliminate vibration during operation, the foundation shall be hard soil without subsidence or distortion, and shall be protective against penetration of groundwater.

b) The foundation shall have no crack, and shall have adequate firmness.

c) The foundation shall be constructed according to the foundation drawings, depth of foundation shall be determined by local soil condition.
