Product Details
This grinder is mainly applicable for grounding processing of disc-shaped parts,circular cutter,bearing collar.piston ring,index plate, circular guide rail,friction plate.saw blades,valves,gears and other circular cutters and gauges.
This grinder 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 grinder is made into pillar-carriage structure and realizes grinding through the grinding wheel rim. Due to this design, high machining precision can be realized; especially that the disc-shaped parts processed may have the same concentric circle planarity 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 reformation and thus enhance the rigidity and rigidity 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 the carriage with the machining efficiency times higher than that of the rectangular surface grinder.
The round table can swivel ±3°, in order to grind the internal and external cones.
The circular table is designed with open-type static-pressure guide rails, and driven by the AC variable frequency motor.
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 guarantee the precision and stability of grinding feed. In addition, the grinder is equipped with quick lifting device.
The main spindle 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, in order to make convenient to grind thin-wall quenched parts with weak magnetic force.
Movement of the table is driven by the hydraulic cylinder,with step-less speed regulation and stable running.
