MW1420 -Universal

 

 

MW1420 (stepless spindle,load weight 100kgs)

M1420 ( spindle speed 60,85,230,120,170,460 rpm/min, load weight 50kgs)

 

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 forgrinding taper.

The wheelhead 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 rollbearing.

The workhead spindle,wheelhead spindle,internal grinding spindle,coolent pump,hydrodynamic and hydrostatic iolpump are driven by separate motors

The spindle of M1450 series is supported by hydrostatic and hydrostatic lubrication,its movement onlow 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 wheelhead of the univeral type(M1450) adopts inverter motor to realize stepless speed changing.the wheelhead 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 workhead of the universal type can be rotate to any position within its conterclock direction 90 degree so it can be suitable for grinding inner or outer surface of taper.

Each moving parts of the machine has eletric,hydrailic 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 diferent distance between the centers for choice.
