For I.D. Clamping – Tork Lok Function

Internal diameter clamping is disadvantageous in terms of gripping torque (machining a diameter with high cutting torque with a small gripping diameter), and there are many secondary operations that require precision, making it a slightly difficult clamping condition.
The AC TORKLOCK Collet & Arbor is a collet chuck with a "TORKLOCK mechanism" that prevents slippage of the contact surfaces even with excessive cutting torque, because the wedge surfaces of the collet and body are precisely machined to make flat contact.
The collet chuck is used in many machine shops because of its retractable function, excellent accuracy and performance, and abundant stock for immediate delivery.

Design-Collet

The internal diameter clamping is disadvantageous in terms of clamping torque (machining a large diameter with a small clamping diameter that requires a large cutting torque), and there are many secondary operations that require high precision, making it a slightly more difficult clamping condition.
The AC Tork-Lok Collet & Arbor is a collet chuck with a "Tork-Lok mechanism" that prevents slippage of the contact surface even under excessive cutting torque.
The collet chuck is used in many machine shops because of its retractable function, excellent accuracy and performance, and abundant stock for immediate delivery.

Pull Back Clamping function and Flat Surface

Both end slit collet and Pull Back function
Precise contraposition flat surface.
No influence even the mutual position of Arbor body and collet changes.
It is possible to add grinding if the clamping range has slightly difference.
