High Performance: Diameter :160mm (6.3 inch );Height : 49mm (1.92 inch). High-performance magnetic steel is used in the magnetic disk, large suction, no magnetic residual, superior holding power. High Precision: Main structural stability, high precision, suctions of up to 100-120N/cm².Suction cups should be cleaned before use to avoid scratches affecting accuracy. Exquisite Workmanship: The panel is processed by a special process, magnetic line is dense, the magnetic poles are evenly distributed, the magnetic force is balanced, and the suction effect on the thin and small workpieces is most obvious. Simple Operation: 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. Wide Application: This magnetic chuck is mainly used in a variety of surface grinding machine, tool grinding machine as a workpiece positioning processing.
