BIG BORE POWER CHUCK (CAH)

• High Gripping Force : By sharply increasing dynamic gripping force, work efficiency and safety have been greatly improved.
• High Speed : Strong gripping force and safety of performance are secured by optimal design, and high speed rotation is achieved.
• Light weight : Equipment load has been reduced by weight reduction, and efficiency has been increased for fitful work and for both forward and reverse operations.
• Durability : Heat treatment is performed to alloy steel, and high accuracy, high strength and high durability are realized by improving lubrication system.
