Performance and Feature

• The grinder is designed into the carriage-carrying mobile structure,with the body section in sealed outlined rectangular shape. Rectangular shape.Rational rib palte arrangements are made and the pillar is made into double-wall frame structure in the most likely bending deformation direction,which guarantees the good non-deformability,surfacient static and dynamic rigidity and thermal stability,from the perpective of structure, and can thus satisfy reauirements for efficient and high pricise grinding.
• The round guide rail of the table is acted by constant volume static guide rail,with four oil chambers on the rail.Pressure oil is supplied to the oil chamber,therefore ,the table can float uniformly and is always in liquid friction during running and the precision of the guide rail can be maintained for long time.cylinder,with step-less speed regulation and stable running.
• The circular table of the grinder is driven by the variable frequency motor through the triangle belt and thus step-less speed regulating can be realized.
• Vertical guide (shaft Y) of the grinding head is acted by the steel-embedded closed rolling guide,which is lubricated with grease and adjusted by pretension applied .In this way ,the easy movement of guide and zero gap fit precision can be guaranteed,as well as the accuracy and stability of grinding capacity.
• The grinding wheel spindle of the grinding head is acted by hydrostatic bearing ,together with a cooling-device- carrying oil supply system.It is driven directly by the built-in motor and is thus featured with low temperature rise,high precision of rotation,small friction coefficient and strong bearing capacity.
• The grinding head botains quick lifting (210mm/m) through the lead screw pair under the driving by the AC motor , it obtains also 0.0025mm (at the minimum) trace feeding from the ratchet wheel and pawl mechanism. with strong lubricants.It runs stably and shows strong abrasive resistance.The reciprocating motion of the table is realized by hydraulic transmission,while travel control maneuvering box is used in the hydraulic system.The identical resetting precision for movement of the table is controlled within eting the requirements on grinding of boss-carrying disc-shaped parts.
