A breakdown published on August 4, 2025, guides readers through the differences between pneumatic and hydraulic power chucks in CNC machining:

• Pneumatic chucks use compressed air for quick, consistent clamping with low maintenance, no oil leakage risk, and cleaner operation—but with limited clamping force and slightly lower durability.

• Hydraulic chucks deliver significantly higher clamping force (often above 3 MPa), superior stability, and integration capabilities for automated systems—but require more complex setup and regular hydraulic maintenance.
