Factory Automatic High Precision  XH7136 Metal CNC Milling Machine Vertical Machining Center for Sale 

This cnc machining center with high quality casting HT300, it also has three quench hardening guideways, wide guide rail & broad span as well as compact & reasonable structure and overall dimension; spindle are driven by frequency conversion motor via timing belt. The machine has milling, drilling, boring, reaming and etc. multiple functions, which could realize complex & high-precision components’ machining upon plates, boards, shells, molds and etc., it is mainly applied to machine high-precision components, it could process plane & slope, groove, holes and etc. of small and medium-sized components. 

• Base, column, worktable, middle slide, lifting slide and etc. all major components are casted and formed by high-strength materials and disposed by artificial seasoning treatment to ensure long-term stability of machine tool and provide guarantee for machine tool stable performance.

• This machine adopts hi-speed, hi-precision and hi-rigidity spindle units, suggesting strong carriage capacity with Max. rotating speed up to 8000rpm;

• X, Y and Z three axis adopts high-precision & high-strength ball screw and servo motor to ensure positioning accuracy of machine tools.

• Guideway and ball screw adopts protection devices to ensure cleaning of ball screw and rails as well as machine transmission & operation accuracy.

• Z axis adds clump weight balancing devices to ensure spindle motion stable and smooth.

• Power-driven lubrication devices could have forced-feed lubrication upon longitudinal, horizontal, vertical lead screws and guideways to diminish abrasion and ensure machine high-efficiency operation; meanwhile, cooling system could change amount of flow by adjusting spray nozzle to satisfy different processing demands.

• Machine operation system could suspend on the top right of machine through suspension arm; this machine conforms to human engineering principle; the spindle box could rotate certain angel, much more convenient & reliable.
