Precision CNC Series Cylindrical Grinding Machine Mk1320b/Mk1332

Product Description

Specificities:
The spindle of the grinding wheel adopts the largetaper four-oil wedge bearing to automaticallyadjust the gap dynamic pressure, which hashigher rigidity and precision of the grinding wheel.eTable (Z axis)drive and horizontal feed (X axis)drive adopts THK ball screw servo direct drivestructure,Table(z-axis)guide rail adopts openunloading hydrostatic guide rail structure, goodrigidity, motion balance, low friction coefficientlow speed and no creep.The transverse-feeo(X-axis)guide rail adopts Swiss linear guiderail and applies pre-tightening forceto meetthe requirements of hiah rigidity. low friction
no clearance and good dynamic response forprecision grinding.
The workhead adopts static spindle top grindingstructure with good rigidity, suitable for precisiongrinding.
Tailstock sleeve adopts linear bearing structureno gap feeding, good rigidity, and can realizehydraulic braking and manual dual mode control.oThe bed adopts double-layer structure(finiteelement analysis),special ratio cast iron castingmanual scraping and grinding of guide rail surface.good dynamic/static rigidity, stable thermadeformation.
