JH7-40 Collet Chuck for Laser Tube Cutting
The JH7-40 sits on the left of the tube-cutting station. The laser head works on the projecting tube, with the chuck and cutting area visible together. The clip shows the physical placement of a hydraulic rotary collet chuck in a laser-tube setup.


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
- Check the hydraulic supply for JH7-40.
- Define cutting position and contact length separately.
- Align tube, support and chuck axes.
