Herat-Magnetic grinding steel needle is polishing machine grinding workpiece special abrasive, also known as magnetic polishing needle. Different specifications of the needle, 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 several times. Pay attention to clean and keep after drying.
According to different materials of processed parts, the recommended needle types are as follows:
For the processing of soft copper and aluminum parts, the diameter of the grinding steel needle can be less than 0.5mm, the length is optional: 5mm,7mm.
For stainless steel and iron and other hard parts, the diameter of the magnetic steel needle is more than 0.5mm, the length is optional: 3mm,5mm,8mm,10mm.
If the aperture and clamping of the machining parts, the diameter of the steel needle is 0.5mm, and the length is 5mm.
