Earth-Chain Rectangular Permanent Magnetic Chucks

The design of the cast iron base section & the brass welded top plate, as well as the rare earth magnetic system, ensures an extremely long & maintenance-free life.

Benefits:

Variable Pitch Poles

• Provide high holding power for thick and thin workpieces.
• Designed specifically for machining on surface grinding machines.
• Pole spacing: steel – 1/4″; brass – 3/16″
• Holding power: maximum 199 lbs./sq. in.

Fine Pitch Poles

• Designed specifically for the machining of workpieces of less than 3/16″ thickness and 1″ diameter or 5/8″ square.
• Pole spacing: steel – 1/4″; brass – 1/16″
• Holding power: maximum 128 lbs./sq. in.

Applications:

• Use for surface grinding or EDM applications

Features:

• Powerful “rare earth” neodymium iron born magnets are 5 times stronger than other magnets.
• Needs no electricity. Provides a constant source or workholding power.
• Low profile design for added clearance.
• Housing and bottom plate are free of magnetism – will not magnetize machine bed or bearings.
• Waterproof and fully submersible.
• Brass welded faceplate can be machined if needed, and protects the magnetic system from penetration of coolant.
