Parameters: Suction: 100-120 N / cm2 Size: 6×18 inch/150×450mm Application: The magnetic chuckcan be used for processing various magnetic conduction work pieces. For surface grinder, tool grinder, EDM and other applications. Thin & light weight work piece are ideally suitable because of fine-pitched magnetic poles. Instructions: Put the workpiece on the suction table, and then insert the wrench into the shaft hole to turn clockwise180°, the workpiece can be sucked for processing. The workpiece is completed, the wrench can be inserted into the shaft hole to turn counterclockwise 180 °, you can remove the workpiece. Maintenance: Sucker should be wiped clean before use to avoid scratching the surface, after using, the surface should be coated with oil to prevent corrosion. Use of ambient temperature: -40 ℃ -50 ℃. Do not knock, to prevent magnetic reduction. Panel with special treatment, no leakage, to prevent corrosion of cutting fluid. To prolong service life of the disk, it can be placed on the cutting fluid for storage. Six-surface fine grinding processing, the sucker can be used in vertical direction on the wire cutting machine cutting. High-performance magnetic steel disk, with suction, almost no remanence. Suction can be 120N / cm2. Item included: 1 x Hex wrench 4 x Mounting tabs 1 x Magnetic chuck
