【Application scope 】Round bar strong permanent magnet chuck is suitable for CNC lathes, circular grinding, vertical machining center. Can be installed in the rotary grinder | suitable for small thin workpiece precision grinding | low residual magnetism can improve thin workpiece grinding; moderate adjustment of magnetic strength. It has the characteristics of high precision, large and uniform suction, safe use, etc. It is a magnetic tool to realize workpiece positioning processing. When charging and demagnetization, the precision of the work surface does not change, and the suction cup is specially treated and non-permeable, which can prevent the corrosion of the cutting fluid, and is suitable for working in the cutting fluid for a long time.
