Pneumatic chucks can have up to three pneumatic ports. Most chucks have two: one for clamping/unclamping and the other for Z-clean, which is an air blast for cleaning the top of the chuck. Some of our chucks also feature a third port for the 'Turbo Lock' feature, providing extra clamping force.
A pneumatic chuck operates in two states: 'Clamp' or 'Unclamp.' By default, all MaxxTooling pneumatic chucks are NC (Normally Closed), meaning they are in the 'Clamp' state when pneumatic pressure is not being fed (OFF) into the clamping/unclamping port.
For ease of use, we refer to 'OFF' when there is no pneumatic pressure being fed into a pneumatic port, and 'ON' when pneumatic pressure is being fed into a pneumatic port.
Clamp state: this state is for working condition, meaning you have something clamped the Chuck. While under “Clamp” state, Pneumatic ports must be:
- Clamp: OFF
- Z-Clean: OFF
- Turbo Lock*: ON
Unclamp state: for releasing what’s clamped on top of the pneumatic chuck. While under “Unclamp” state, Pneumatic ports must be:
- Clamp: ON
- Z-Clean: ON
- Turbo Lock*: OFF
*Only if the chuck has Turbo Lock Feature.
