M14 series cylindrical surface grinder is suitable for grinding outer/inner surface of cylinder and taper.

The longitudinal movement of the workable is driven by hydraulic or by handwheel,the worktable can rotate to a certain degree so as to be suitable for grinding taper.

The wheel head cross feed is driven by hydraulic,which realizes automatic periodical feed and rapid feed.it can also do rough and fine feed through handwheel.

M14 series universal cylindrical grinder has internal grinding apparatus,internal grinding spindle is supported by precise roll bearing.

The work head spindle,wheel head spindle,internal grinding spindle,coolant pump,hydrodynamic and hydrostatic oil pump are driven by separate motors

The spindle of M1450 series is supported by hydrostatic and hydrostatic lubrication,its movement on low speed is smooth.

The spindle of M1450 series is supported by hydrostatic and hydrodynamic bearing of high rigidity,it makes the spindle have high rotary accuracy and perfect rigidity.

The wheel head of the universal type(M1450) adopts inverter motor to realize stepless speed changing.the wheel head spindle of the universal type ( M1450) adopts sliding bearing structure.the clearance of the front bearing can be adjusted to make it suitable for the grinding use center or chuck the work head of the universal type can be rotate to any position within its counterclock direction 90 degree so it can be suitable for grinding inner or outer surface of taper.

Each moving parts of the machine has electric, hydraulic and mechanic interlock structure the machine is well designed with pleasing appearance,all control lever are centralized in panel make operating easy.

The wheel dresser can be assembled on the worktable surface or on the tailstock.

There have many different distance between the centers for choice.

 

Standard accessories:

(1) complete set of electrical equipment  (2) coolant equipment   (3) wheel periphery dresser  (4) wheel flange     (5) wheel balancing arbor       (6) leveling wedge

(7) open type steady rest   (8) carbide tipped center

 

Optional accessories:

(1) wheel balancing stand  (2) magnetic separator   (3) center grinding attachment 

(4) close type steady rest   (5) end wheel dresser   (6) radius wheel dresser
