Both zirconia balls and steel balls can be used for grinding and polishing, as abrasives, as well as for bearings, balls, and positioning balls.
Steel balls are divided into carbon steel balls, bearing steel balls, stainless steel balls, (stainless steel balls are further divided into martensite, austenite) copper balls, aluminum balls, etc. Different materials have different densities, different densities have different qualities, and the number of particles per kilogram is also different. The greater the density, the greater the unit weight of the same specification, and the less the number of grains contained in one kilogram.
1. The density of carbon steel balls, that is, the density of carbon steel is 7.85g/cm3;
2. The density of bearing steel balls, that is, the density of bearing steel GCr15 is 7.81g/cm3;
3. Austenitic stainless steel ball is 300 series, 304 density is 7.93g/cm3, 316/316L density is 7.98g/cm3;
4. The density of martensitic stainless steel ball, namely 400 series, is 7.75g/cm3;
5. The density of brass ball H62/65 is 8.5g/cm3;
I
n terms of specifications, the main specifications of steel balls are Φ0.5mm～Φ250mm, and the conventional specifications of zirconia beads are 0.03-50mm.
According to the different zirconium content, zirconia beads can be divided into 95 zirconium beads, 80 zirconium aluminum composite beads, cerium oxide zirconium beads, 65 zirconium silicate beads, etc.
1. 95 zirconia beads 6.0g/cm3;
2. 80 zirconia balls 5.2g/cm3;
3. 65 zirconium silicate beads 4.0g/cm3;
4. Wheel polishing zirconium beads 3.2g/cm3;
5. Cerium stabilized zirconia beads 6.1g/cm3;
Both steel balls and zirconium beads can be used for grinding, such as in tissue grinders, grinding hair, animal tissue, leaves, etc. In polishing, the surfaces of steel balls and zirconium beads are very smooth, and can be used for mirror polishing to polish workpieces Polishing, steel balls are used as abrasives to polish, and after polishing, the workpiece will become black.
