Judge the quality of the ball.
A steel, cast iron, alloy steel ball, the material influence, etc., the density of different materials of different medicinal materials crush with steel ball, steel density is larger than the cast iron, alloy steel, in accordance with the main alloy elements and content of different density and different.
Second, the influence of the steel ball manufacturing methods: bearing steel ball rolling and forging steel ball its compact structure, so the density is big, the casting of cast steel, cast iron ball or casting alloy ball and so on organization is not very dense, even including porosity, so the density is small.
The influence factors of steel ball quality.
The influence of steel ball and metallographic structure: the density of martensite, austenite, bainite, ferrite and other crystal structures is not the same, and the steel analysis instrument has influence on the fineness of crystallization.
ow to polish stainless steel balls:
Stainless steel ball polishing method basically has two kinds: first, with a barrel after the heat treatment of stainless steel ball with gold black, on the surface of the steel grit removal time roughly 12 hours, until the stainless steel ball surface is smooth, and then use clean water, into the light magnesium oxide, and then 6 to 12 hours, after take out into the grinding vibration polishing machine, add brightener and cleaning agents, respectively, after light wash and tumble dry.
This kind of polishing method is mainly applicable to 304 steel balls, 316 ball bearings and 201 stainless steel balls.
The other kind is mainly 420 stainless steel ball, 440C stainless steel ball, this kind is mainly fine grind, natural wear bright.
