AC Servo Motor Drive   Micrometric Adjustment for Cross Feed

The vertical Feed (Y-axis) is driven by Mitsubishi (or equivalent) servo motor, which is connected with high precision worm gear mechanism.
It provides minimum feed unit in 0.001mm or rapid traverse rate up to 300 mm/min.


The micrometric adjustment is transmitted through a worm and worm gear mechanism.
The worm is manufactured from carbon steed, hardened and precision ground. The worm gear is manufactured form phosphor bronze. A high precision ball screw is equipped on the cross feed axis for high precision transmission.

Digital Readout for Linear Scale   Vertical Servo Feed Control Panel

VERTICAL FEED(Y-AXIS): The encoder for servo motor transmits a position signal to digital readout, which displays the position. Amy position display allows for zero-setting.
CROSS FEED (Z-AXIS): When a linear scale is fitted on the z-axis, the cross feed position can be displayed and allows for zero-setting.


The control panel provides a selector for selecting 1um and 10um feeds and rapid traverse.
This allows operator to fast move the spindle head to approach the work price, then turn the MPG handwheel to move the spindle head to work price for grinding, the control panel is easy to access for added convenience of operation and increasing working efficiency.
