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.
Note: the surface grinding machines of M7140, M7150 and M7163 can be either type B (the distance from the center line of the spindle to the table is 1000mm) or type C (the distance from the center line of the spindle to the table is 1400mm), other parameters are the same as type A (except the height and net weight of the machine).
