Product Description
Normal Horizontal Axis Rotary Table Surface Grinder
RSG-400     RSG-500    RSG-630
 
Performance and Feature
This grinder is mainly applicable for grounding processing of disc-shaped parts,circular cutter,bearing collar.piston ring,index palte,circilar guide rail,firction palte.saw baldes,valves,gears
and other circular cutters and gauges and it can be widely used by the manufactures of tools,bearings,values,gears,auto parts.semi-conductors,optical elements and other engineering works for grinding processing of precision components.
The horizontal shaft circular table surface grinder is made into,pillar-carriage structure and realizes grinding through the grinding wheel rim.Thanks to this fesign,high machining precision can be realized; especially that the disc-shaped parts processed may have the same concentric circle palnarity and relatively high surface roughness can be realized.
Designed with compact structure and rational layout,the grinder takes up small land area.The grinder body is made into double-layer-wall structure,with consistent temperature rise at the four sides so that to avoid thermal seformation and thus enhance the rigidity and rigity and realize good stability.
Guide rail of the grinder body is designed into open static pressure one-flat-one-V structure which guarantees stable running ,high shock absorption,less mechanical wear and long service life.The table moves stably on the guide rail,with uniform stress and high movement precision.
At the time of machining,the round table rotates and starts reciprocating feed movement in the vertical direction along with th carriage with the machining efficiency times higher than that of the rectangular surface grinder.The circular table may revolve along the horizontal shaft for ±3°,so that grinds the internal and external cones.
The circular table is designed with open static pressure guide rail and the AC motor VVVF speed control system for rotation driving.The grinding head feeds vertically through the quill roller steel guide to adjust pertension force,which guarantees the easy movement of guide ad zero gap fit and finally guarantrrs the precision and stablility of grinding feed.In addition,the grinder is equipped with quick lifting device.
The main shaft of the grinding head is made into dynamic-static-pressure bearing bush supporting structure and is driven directly by the built-in motor,together with a stand-alone forced cooling oil tank,which may realize low temperature rise and high precision of rotation.
The feed system of the grinder is designed with functions including automatic feed ,zero stop ,sparking out,automatic stop and automatic demagnetization grinding and the automatic circulating device.Magnetic force of the electromagnetic chuck is adjustable,so that to make convenient to grind thin-wall auenched parts with weak magnefic force.Movement of the table is drivem by the hydraulic cylinder,with step-less speed regulation and stable running.
