Rear-chuck assemblies for laser tube cutting machines with pneumatic rotary unions and visible air connections
Application example

Laser Tube Cutting Rear Chucks

BP-3P-0004 and BP-2P-08-0001 are used to carry compressed air to rear chucks on laser tube cutting machines. Choose the passage count and interface to match the chuck design.

Process or assist gases need a separate solution. Tell us the gas and operating conditions so we can check materials, cleanliness, and testing.

Standard models used for rear-chuck compressed air: BP-3P-0004 and BP-2P-08-0001 for laser tube cutting machine applications.

The photograph shows the application type; the exact model in the image has not been identified.

CNC Pneumatic Clamping Fixture

BP-2P-130-0001 is installed at the rear of a custom CNC fixture on a circular-blade saw machine. Two independent compressed-air passages operate the clamp and release functions.

For a similar fixture, send a model, photo, or drawing. Add the pressure, speed, and mounting details if you know them.

Bottle-Capping Head

BP-2P-16-0001 is installed in a production capping machine. Two independent passages carry compressed air for clamping and releasing the pneumatic three-jaw gripper.

For a similar machine, send a model, photo, or drawing and we will check the closest configuration.

Engineering Inputs

What to send for an application review

You can start with a machine type, model number, photo, or drawing. Share any of the details below that you know, and we can narrow the choice to a catalog model or custom option.

  1. 1
    Medium and function

    Identify what each rotating passage carries and what the circuit does.

  2. 2
    Passage count

    List the functions that must remain independently controlled.

  3. 3
    Pressure and speed

    Provide the maximum pressure and rotational speed for the machine.

  4. 4
    Mounting interface

    Share the available envelope, thread or flange, and connection direction.

  5. 5
    Drawing context

    Attach a 2D drawing, STEP assembly, or marked-up installation sketch when available.

Not sure which model fits?

Send the machine conditions before choosing by model number.

Our engineers can review passage functions, the operating envelope, and the installation interface together.

Standard or Custom

Your machine does not need to fit an existing category.

Begapunk can review a custom passage layout, mounting dimensions, connection positions, body and seal requirements, and 2D/3D assembly context for OEM machinery.
