Oct. 31, 2024

Front-mounted pneumatic chuck, chuck with built-in cylinder and check valve, no traction rod and reverse cylinder, simple chuck device, 

quick clamping system, pneumatic chuck cylinder increase, progressive clamping force high flexible work, spindle with through-hole planning, 

spindle must be stopped for loading and unloading, suitable for modification of lathes, welding equipment, etc.

Remove the original fixture from the lathe, install the flange with the chuck, trim it, measure the axial and radial runout (≤0.005),

 connect the chuck to the flange stopper with screws and measure the outer circle of the chuck (≤0.04); 

the anti-rotation positioning bracket is installed in the correct direction of the machine tool, and the bracket device is reliable.


Avoid resonance between the chuck and the machine cover when rotating, and avoid connecting with the machine cover to avoid noise. 

Note: The anti-rotation screw should have a swing space of 0.5-1mm on the bracket, and do not fix or shake the screw.


Connect the air source and switch the solenoid valve switch to confirm that the chuck operates normally,

 lock the relevant screws and check the chuck reversal resistance at a low speed to see if the resistance is normal, 

and then enlarge the chuck claw radially according to the workpiece size. 

You can keep the distance based on the number of combs (each pitch is 1.5 mm, see the specific parameter table).
