Product Details
The grinder adopt the carriage-carrying mobile structure, and the body section is in sealed outlined rectangular shape. Rational rib plate arrangements are made and the pillar is made into double-wall frame structure on the bending deformation direction, which guarantee the good non-deformability, sufficient static and dynamic rigidity and thermal stability, from the perpective of structure, and can thus satisfy requirement for efficient and high precise 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 each 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.
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 (Y-axis) of the grinding head adopts 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 adopts hydro-static bearing, together with a cooling-device-carrying oil supply system. It is driven directly by the built-in motor and featured with low temperature rise, high precision of rotation, small friction coefficient and strong bearing capacity.
The grinding head obtains quick lifting (210mm/m) through the lead screw pair under the driving by the AC motor, it also obtains 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 0.1mm, which meeting the requirements on grinding of boss-carrying disc-shaped parts.
