Equipped With:
10" x 20" Electromagnetic chuck Sony 2-Axes DRO System on Z & Y Overhead Dresser Coolant System 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 interlock between electrical cabinet door and power supply is established to ensure safe operation. 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.
