High/Low Chucking
Northfield Precision announces the development of two methods of high/low chucking: “on the fly,” and “cycle interrupt. ” Using a proprietary valve system, delicate parts can be rough machined and finished in one chucking. The cycle starts with the jaws clamping at high pressure for roughing, then dropping down to low pressure for finishing.

The company features two styles of magnetic workholding devices: permanent magnetic blocks and electro-permanent magnets. According to the company, magnets are ideal for machining flat stock steel because they provide access to five sides of the workpiece. Part setups are quick and easy, the company says, and the magnetic devices maintain maximum hold-down force.
