Machine Description

3-Axis fully automatic and plunge grinding system

Spark-out 0-9 times for fine finish

Precision roller bearings on longitudinal and cross feed guiderails

Heavy duty spindle with 2 sets of class 7 super precision angular contact ball bearings

Hardened and ground cross feed and elevating lead screws

Microprocessor control system for ease of operation and trouble free production

Hardened and ground guide ways for durability

Quick table and cross feed stroke adjusting device

Wheel head will raise up automatically and table parks at left or right side after cycle is completed 

All castings are specially designed for permanent stability. They are made of special wear resisting alloys, and scientifically stress relieved.

The maximum distance from table surface to spindle centerline is 21″ which provides more clearance for grinding.

The spring loaded type table travel stops will dampen the over travel caused by abnormal operations. 

The optimum span of double V crossfeed guideways is designed based on bending moment, kinematics and supporting force.

All essential castings are made of high grade Meehanite cast iron that is stress relieved through annealing to eliminate internal stress. With the greatest stiffness and stability of the castings, this machine is suitable for both precision surface grinding and form grinding.
