Switchable Permanent Magnet
Whether milling, turning, drilling or grinding, MPI’s switchable permanent magnet (SPM) will hold your workpiece in place
with a strength previously unattainable. Technological advances uncovered by MPI’s engineering team and applied to the
design of the SPM allow this workholding magnet to deliver four to ten times the holding power of competitive products.
Not only does the SPM boast significantly better power, it also houses this magnetic strength in an enclosure that is
typically more than 50% smaller than other comparable units. MPI’s switchable permanent magnet is the only SPM able
to handle thin gauge metals, which often do not accommodate the use of magnet workholding devices.
The SPM is more powerful than anything available on the market, and surpasses the strength of an electromagnet. While
electromagnets need continuous and expensive electrical power to maintain magnetism, MPI’s SPM requires electricity
only to turn it on and off. This benefit is two-fold. One, less electrical power means lower utility costs. Two, the
elimination of continuous electrical power means the SPM is safer to operate than an electromagnet. Should power be
interrupted, the SPM retains its magnetism and continues to hold the workpiece without the need for an expensive battery
back-up system. In comparison, an electromagnet that losses power will immediately release the workpiece, sending it off
the machine tool and creating a significant operator safety issue. You can rest assured that the SPM will hold your
workpiece in place reliably as intended.
Standard Features:
• Stays on until the job is done!
• Maximum holding power: 4 – 10x stronger than similar sized electromagnets
• Available in various sizes and styles
• Requires electrical power only to switch on and off
• Accommodates thin and thick gauge metal parts
• Provides uniform clamping force
• Safely holds the workpiece even if the power goes out
• Ideal for milling, turning, drilling or grinding operations
• No loss of magnetic power over time
• One (1) controller can operate multiple units
