PMM SERIES Rectangular Permanent Magnetic Chuck, Magnetic Chuck For Milling and Planing, Permanent Magnetic Workholding Systems
Rectangular Permanent Magnetic Chuck use magnetic force to hold a workpiece in place while it is being worked on. The magnets work by inducing polarity into the ferrous work material that connects across its north and south poles. When a workpiece is placed across the poles of the magnet, the flux flows into it. The ferrous components have poles that are opposite the polarity of the magnet so they attract each other. Amplifying and controlling this flux is the key to applying magnets in a metalworking operation.
Closing the gap between the workpiece and the magnet increases the attraction or “pull” of the magnet. Smooth surfaced workpieces are more tightly held than rough surfaced. The strength of the magnetic attraction is a function of how much magnetic flux can be induced into the workpiece.
With transverse pole pitch, p:15m, permanent neodymium-magnets, enhanced holding force
Rectangular Permanent Magnetic Chuck Use:
Heavy machining, such as milling and planing.
The dense, concentrated magnetic field enables it to be used for small, medium and large workpieces, including those with rough or uneven surfaces. The magnetic field is without any stray fields, preventing magnetization of
the tool.
Rectangular Permanent Magnetic Chuck Features:
Exceptionally strong neodymium magnetic system. ON-OFF control by means of hand lever. In the OFF position, a weak opposing field eases the removal of the workpiece. The magnets are equipped with longitudinal and transverse stop rails.
Laminations 3 mm brass / 12 mm steel.
Suitable for use with laminated topplates:
Nominal holding force: 150 N/cm2
Magnetic field height: 12 mm
Pole plate wearing limit: 5 mm
