M7140A3 - Hydraulic

M7140A3 /1250x400mm

 

* Compact structure, and easy operate.

* Hydraulic transmission on longitudinal manual and auto feed on transverse, rapid movement and micro-adjust mechanism on vertical.

*  The guide ways of saddle and bed is adopted with V type and plane guide pair and the low guide ways are adhesive with plastic, so that the moving is facile and light.

* DRO can be selected

* Rapid moving up or down is driven by the micro motor located on the lower of grinding head body. Drive the worm pair to complete the rapid movement. When working, pull the micro setting handle on bed to engage the worm. Then push the button on the panel. If feed by hand, disengage the micro-worm on bed to turn the hand wheel, when micro-feed, put the micro-adjustable knob to engaged the worm and turn the micro-adjusting handle to realize the micro-feed. The lead screw pair timing wheel and micro-motor is located in the saddle of bed.
