BJTDLLX Permanent Magnetic Chuck, 4''x7'' Surface Grinder Permanent Magnetic Chuck, Rectangular Chuck Fine Pole Magnetic Chuck Powerful Sealed Chuck For Grinding Machine, 100N-120N Suction Force

--Magnetic pole gap fine, uniform magnetic force, small workpiece processing, the effect is particularly evident. --With industrial pure iron test, the vertical tension up to 100-120N/cm2. --Tungsten steel, hard alloy steel and other magnetic small workpieces are not suitable for magnetic sucker. On the other hand, its panel brass welding and treatment can prolong the corrosion of cutting fluid. 【High Efficiency】: This permanent magnetic chuck adopts an optimized magnetic circuit design so that there is almost little residual magnetism after machining so that the machined work piece can be easily taken off with higher efficiency. 【Strong Magnetic Force】: This permanent magnetic chuckuses high-performance magnets with strong magnetic force and less residual magnetism. 【High Precision】: This permanent magnetic chuck is made of professional material with parallel accuracy within 0.01mm/0.000394in and a magnetic pole pitch of 1.5+0.5mm/ 0.059+0.019in for high precision and remarkable processing effect. The accuracy of the disc surface does not change even when the permanent magnetic chuck is opened and closed. 【Easy to Operate】: The use of this permanent magnetic chuck only requires a wrench to control the shaft hole to complete its operation. Simple operation makes the permanent magnetic chuck easy for even beginners to master.
