Magnetic Polishing Needle is a special abrasive for polishing machine grinding workpiece, also known as magnetic polishing needle. Specifications and models of different steel needles, polishing strength will be different.
Steel needle selection of imported SUS304 stainless steel, service life: 3-5 years. The grinding steel needle is a semi-permanent grinding material, which can be used continuously for many times. Pay attention to Changshacleaning and drying before storing.
According to the materials of different processing parts, the recommended steel needle models are as follows:
For processing soft copper and aluminum parts, the diameter of the grinding steel needle is 0.5mm or less, and the length is optional: 5mm,7mm.
For stainless steel and iron and other hard parts, magnetic needle diameter size selection 0.5mm or more, length optional: 3mm,5mm,8mm,10mm.
If the aperture and seam of the processing parts, the diameter of the steel needle is 0.5mm, and the length is optional: 5mm.
