Compensation not required due to stable dimensional change from cold start. Low vibration technology produced utilizing JTEKT overhaul engineering to enable high class grinding Achieves high accuracy and low vibration rotation by balancing motor parts. This reduces wheelhead vibration by 70% and achieves a high quality grinding surface (mirror grinding). Equipped with a coolant unit for grinding high accuracy parts. *optional specification Clean coolant is supplied to the machine through the removal of minute chips that conventional units are unable to eliminate. Clean coolant enables the grinding of parts that require high accuracy (surface grade).
