GL4SⅢ-Premuim CNC cylindrical grinder

■ Stable dimensional change from initial workpiece -thermal displacement minimizing structure.

■ JTEKT's overhaul engineering and low vibration technology achieve high quality grinding.

■ Equipped with a coolant unit for high accuracy grinding parts. *optional specification.

Including all high-precision technology.

■ Stable dimensional change from initial workpiece -thermal displacement minimizing structure.
· Thermal displacement is suppressed by cooling heating components such as the wheelhead, workhead and motor.
· Compensation is unnecessary due to stable dimensional change from cold start.

■ JTEKT's overhaul engineering and low vibration technology achieve high quality grinding.
· Achieve high accuracy and low vibration rotation by balancing motor parts.
This can reduce wheelhead vibration by 70% and achieve a high quality surface grinding (mirror grinding).

■ Equipped with a coolant unit for high accuracy grinding parts. *optional specification.
· Clean coolant is supplied to the machine and able to remove tiny abrasive dust which is hard to be removed by now.
· Clean coolant enables high accuracy grinding of parts (surface grinding).
