Kev xaiv ntawm superhard abrasives
Mar 30, 2022
(1) Kev xaiv cov abrasives
1. Synthetic pob zeb diamond yog tsim rau kev sib tsoo ntau yam ntaub ntawv nkig. Xws li: sib tsoo cov cuab yeej carbide, honing alloy cam khwb cia hlau lub tog raj kheej liner, txiav thiab sib tsoo, polishing ntau yam ferrites, sib nqus hlau, thiab lwm yam.; blanking ntawm optical iav, txiav thiab milling, zes, zoo sib tsoo, edging; Hlau ua gemstones, iav, siab -alumina ceramics, ntoo thiab lwm yam.
2. Cubic boron nitride: haum rau kev sib tsoo cov ntaub ntawv nyuaj thiab ductile xws li: ferrous hlau, siab alumina steel, stainless hlau, cuab yeej steel, bearing steel, tuag steel, siab steel, siab steel, hardened steel, thiab lwm yam.
(2) Kev xaiv ntawm particle loj
Nyob rau hauv kev xaiv ntawm particle loj, yam xws li workpiece roughness, sib tsoo efficiency, thiab abrasive noj yuav tsum tau txiav txim siab. Nyob rau ntawm qhov chaw ntawm kev ua kom cov workpiece roughness, coarser particle loj yuav tsum tau xaiv kom muaj kev sib tsoo efficiency.
Kev xaiv dav dav ntawm particle loj:
Coarse grinding: 40/50—120/140
Semi-fine grinding: 120/140—200/230
Fine grinding: 200/230—325/400
Super fine grinding: W40—W28—W209
Grinding and polishing: 36—54—0—0.5c percent
