Product description

Magnetic grinding steel needles are specialized abrasives used by polishing machines to grind workpieces, also known as magnetic polishing needles. The polishing strength of steel needles with different specifications and models will vary.

The steel needle is made of imported SUS304 stainless steel, with a service life of 3-5 years. The grinding steel needle is a semi permanent grinding material that can be used multiple times continuously. Pay attention to cleaning and drying before storage.

The recommended steel needle models for different processed part materials are as follows:

For copper aluminum parts with softer processing materials, grinding steel needles with a diameter of 0.5mm or less is sufficient, and lengths can be selected: 5mm or 7mm.
For harder parts such as stainless steel and iron, the diameter of the magnetic steel needle should be greater than 0.5mm, and the length can be selected as 3mm, 5mm, 8mm, or 10mm.
If the aperture and gap of the processed part are selected, the diameter of the steel needle should be 0.5mm, and the length should be 5mm.
