A magnetic conductive coverplate of leakage type that may used in magnetic holding devices covers a holding surface of the magnetic holding device. The leakage type magnetic conductive coverplate is made integrally of a single magnetic conductive material. The leakage type magnetic conductive coverplate can conduct magnetic force of the holding device into a workpiece so as to hold it. Because the leakage type magnetic conductive coverplate is made integrally of a single magnetic conductive material, when there is any change in ambient temperature, no crevice will be produced due to different coefficients of expansion and contraction. Therefore, any coolant used in workpiece machining and any magnetic conductive impurities will not infiltrate into or enter the magnetic holding device to lose the internal insulation, thus effectively protecting the internal structure of the magnetic holding device and remarkably improving durability and service life of the magnetic holding device.
A removable magnetic conductive coverplate of leakage type for use in a fully functional magnetic holding device, the magnetic holding device comprising a base having a bottom and a surrounding slide wall perpendicular to the bottom, wherein a cavity having an opening at an upper portion thereof is formed by the bottom and the surrounding side wall, and a holding surface defining the opening at the upper portion of the cavity and formed jointly by a plurality of source magnets and a non-magnetic-conductive material, wherein the leakage type magnetic conductive coverplate covers the holding surface of the magnetic holding device and the leakage type magnetic conductive coverplate is fabricated integrally of a single magnetic conductive material.
A fully functional magnetic holding device of leakage type comprising:
