JH/JA Integrated Spindle and Collet Chuck Unit
This bench demonstration shows a collet chuck, spindle mounting unit and timing-belt drive together. The operator turns the assembly to show the front opening, rear pulley and mounting bracket. It explains the layout of an integrated gripping and rotary-drive unit for tube-cutting equipment.
How the grip works
The JA/JH family combines the actuator and rotary gripping unit. JA uses pneumatic actuation. JH uses hydraulic actuation. A matching collet grips the part while the machine drives rotation. Select the drive pressure, collet size and spindle connection as one setup.
The gripping position controls access for a cutting tool or laser head. Long tubes and shafts also need a suitable support and feed arrangement. Set the part projection, support position and working area before fixing the chuck and its mounting unit in place.
What to check in this setup
- Match spindle and chuck mounting interfaces.
- Leave guarding space around pulley and belt.
- Plan feed and support for the tube length.
