grinding machines M7140 cylindrical grinding machine
Product Description
STRUCTURAL FEATURES:
The machine tool adopts the t-type layout form, the guide rail on the column is equipped with a drag plate, the middle position of the guide rail is equipped with a vertical feed mechanism, the transmission accuracy is high, the interchangeabil- ity is good, the cross joint is connected in the transmission process, can compensate the center error of the lead screw and the reducer shaft. Closed hydraulic system is adopted for the movement of the worktable. The front and rear feed can be manually fed, the hydraulic feed can be automatically fed, and the lead screw can be fed automatically intermittently driven by a variable frequency motor. Adopt high strength cast iron foundation, grinding head spindle adopt bobbin or high rigidi- ty sleeve structure, the machine overall rigidity is strong, the quality is stable, the operation is stable.
