Function:
1.This machine is mainly used for milling holes for large and medium-sized parts as well as other processing such as hole drilling, expanding, reaming and plane milling.
2.Main transmission system of TK6920A machine adopts AC motor, which can realize stepless speed regulation. It also has 4 mechanical variable speed regulations by using handle for control.
3.AC motor drives axial motion of spindle, motion of facing head radial tool post, vertical motion of headstock, longitudinal motion of front column. The stepless speed regulation is acquired by change of mechanical variable speed two and electric speed regulation. Electromagnetic clutch controls the mechanical variable speed regulation.
4.Guideway of sliding carriage and headstock of the machine are imbedded soft band which reduced coefficients of kinetic friction and static friction and ensured running stability.
5.Hydraulic lubricating system consists of domestic top brand hydraulic parts; guideway and lead screw are lubricated by auto-lubricating system.
