Operating Tips:

Column Moving Surface Grinder (SG-81160FR, SG-81220FR, SG-81250FR, SG-81300FR, SG-81400FR)

1.Double walled column construction ,provide high rigid support .Adopt counterweight balance,make the machine move stably ,and reduce the load of the ball screw,keep the accuracy for a long time.
2.Adopt rectangular guideway coated with TURCITE-B belt,to get low friction coefficient,good abrasive resistance and high rigidity.
3.Adopt flat-V guideway on longitudinal and transverse to get good guidancequality,coated with TURCITE-B belt ,precision handscraping to keep stable work accuracy.
4.AC servo motor drives on transverse and vertical movement,electronic hand wheel(MPG)replaces the tradition mechanical hand wheel,to get high accuracy and easy operation,with little impact.
5.Independent,large capacity integrated hydraulic tank,assemble with air cooling and pressurizer,isolate heat and vibroseis,to provide excellent power for precision grinding.Adopt hydrostatic bearing for the grind spindle to get high rigidity(High precision ball bearing for export),together with 18.5Kw motor to provide strong power,apply to the heavy machining.Spindle rotation is supported by rigidity oil layer,no wear,ensure the long-term precision and life.
6.Adopt SIEMENS touch panel .It makes the operation simple and interesting by using powerful and friendly human-machine interface.
7.Hydraulic drive for the work table ,after adjusting meticulously,the table moved stably with little impact.
8.Special design,elegant appearance,good srability.
9.Well designed machine bed is one high grade casting piece,which insure heavy duty cutting .
10.Strengthen ribs are set inside of the column,make sure the great stability support for grinding spindle.
11.Super great power grinding spinel is most import of the machine.
12.The machine bed and rear sliding bed is assembled to one strong piece.
