Magnetic Machine Bed

Shree Magnets Private Limited offers MagnaSlot – a complete magnetic machine bed, an invention necessitated by the growing demand for versatility in machine tool industry. Historically, the industry has moved on from machine tools designed for a specific purpose, viz., SPM, to machine tools which are universal in nature. Development of magnetic beds has also moved on from permanent magnetic beds to electro magnetic beds and then to the EPM – Electro Permanent Magnetic beds with its instantaneous clamping and electrical independence. But the inherent drawback of a magnetic bed comes to fore when the customer wants to mount a non-magnetic material. The solution is to remove the magnetic bed and clamp other forms of clamping devices to the machine bed or clamp the secondary clamping device on to the magnetic bed. Removing the magnetic bed frequently from the machine is not always easy and may lead to damage to the original machine bed. Another drawback of orthodox magnetic bed is that the top surface is always made up of two different materials, either steel or aluminium/brass/stainless steel or epoxy. The dissimilar materials used at top surface leads to uneven thermal expansion during machining creating inaccuracy in the clamping face. Secondly if there is any crack in the non-magnetic materials, seepage of external liquids takes place damaging the magnet. MagnaSlot was developed to overcome these and other such problems in the orthodox magnetic beds and with an eye on versatility.
