For use on modern CNC lathes.Positive Lok Power chucks are with large through holes suitable for both bar work and chucking of flange type parts.

The chucking power is transmitted by means of proven wedge system. Stable zigzag design work against high pressure and provide long tolerance and high accuracy at the same time.

Features:

1. The dustproof patent structure can prevent the metal chips get into the chuck inside.
2. The clean hole design can blow air into the chuck internal to clean out the residual chips and coolant.
3. The drainage plate structure design can prevent the coolant get into the spindle internally.

1. Superior Clamping Force: Provides strong and stable clamping to handle high-speed and heavy-duty machining operations.
2. High Precision: Minimizes runout and ensures excellent concentricity, delivering exceptional machining accuracy.
3. Versatile Applications: Available in various configurations, such as 2-jaw, 3-jaw, and 4-jaw designs, to accommodate different workpiece geometries.
4. Durability: Constructed with high-grade materials to withstand wear and ensure long operational life.
5. Smooth Operation: Designed for fast and efficient clamping and unclamping, reducing production downtime.
6. Customizable Options: Offers a range of sizes and specifications to suit specific machining requirements.

High precision turning or rotating air chucks are designed to be mounted on any CNC turning and conventional machine. The speed for rotating precision air chuck is up to 6000 rpm. Controlled clamping force enables clamping of thin-walled and other gentle parts with no distortion. Most models come with coolant or air passage through the center of the chuck.

It is very simple to mount the air chuck on the CNC lathe machine.

An experienced operator may do it in several minutes.

Simple loading and unloading. Most chucks come with 2, 3, or 4 jaws as standard.

Most standard models are available in inventory.

The pneumatic chuck accuracy is 0.002mm or 0.0001".

Chuck size ranges from 50mm to 350mm
