Electro Permanent Magnetic Chucks

• Reinforced Electro permanent systems with extremely High magnetic power.
• Absolute safety against Power or Cable Fault.
• Cold operating ensures Ultra Precision machining.
• An enormous Reduction in clamping and setup times.
• Customized solutions to suit your requirement.

Combines the clamping force of high quality Permanent Magnets with the advantage of switching facilities an Electrical Devices is thereby providing in piratical applications all the prerequisites for precision, safety and ease of operation. A totally original and unique Electro Permanent system is controlled electronically and the clamping zone comprises of a series pf alternate poles. An electric impulse of very high magnitude but of a very short as the chuck is switched ON with the job completing the magnetic circuit the magnets work at BH. Rem & hence is able to provide a magnetic energy perfectly suitable for heavy cuts and thrusts during Grinding, Planning and Milling operations. With these properties we can provide you performance results which has so far been unobtainable from conventional permanent magnetic chucks and hardly obtained in best electromagnetic chucks available.

The solid construction of the EPM chuck eliminates mechanical distortion and unlike electromagnetic chucks there is in heat generation hence the chuck when once attached to the machine bed will be as geometrically stable as the machine itself providing working surface with uniform holding power required of precision machining. The chuck is entirely static and hence it is not subject to mechanical wear.

The Electronic Control unit is specially designed for Easy and Safe operation of Electro Permanent Magnetic Chucks. Power circuit is controlled by Thrusters and is operated by Remote Control. The switching On/Off of the chuck is done by means of Illuminated push-buttons. The Power consumption is considerably reduced saving almost 98% of precious energy, as only a current pulse for few seconds is required to switch the chuck on and off. Hence the running and maintains cost of the EPM chucks are virtually nonexistent. When in operation the chuck is entirely isolated & independent of power supply. This gives total security against POWER FAILURE and eliminates any risk of accidental release of work piece.

EPM chucks are available in Grinder series and Milling series in sizes from 200 mm to 1500mm in length and 150 to 400mm in width having longitudinal or transverse poles. Large Magnetic area can be arranged by multiple mounting of chucks which can be operated by a single controller. Special designed to suit yiour particular applications. They are supplied in full working order complete with side plates and power supply cable.

• No electricity required to keep the chuck ON.
• All Metal Top Plate of Brass and Steel lamination provides full active area.
• Variable power makes it possible to adjust the magnetic force.
• It drastically reduces the loading, unloading the work pieces.
• Hold all type and sizes of work pieces.
• No heat built up, no deformation provides high precession accuracy.

• For grinding application of all sizes of jobs.
• These chucks are suitable for horizontal spindle surface grinding machines as the main cutting thrust is towards the length of the chuck, poles at right angle of the wheel give more gripping of the job.

• These chucks are also available in long pole design.
• Large area can be arranged by multiple mounting of chucks side by side which can be operated by a single controller.
• Special purpose chucks can also be designed to suit particular applications.
• Pole pitch of 2mm (1.5+0.5) can be made at extra cost.

All dimensions are in mm.
