Product Details
(High anti-rust type (AA) & super wear-resistant type (A))
A:
material:
① Super-high anti-rust high wear resistance stainless steel series(AA) (HRC54°±2°Section)(regularly stock)
② General anti-rust high wear resistance stainless steel series(A)
(HRC45°~64°Section series)
B:
Hollow core inner hole process grade (independent of material grade & edge process grade):
① AA grade: raw material with hole + pure mirrow grinding of hollow core inner hole (hollow core inner hole ▼▼▼▼ &R0.01) (AAA) (high cost, not commonly used)
② AA grade: raw material with holes, CFDA standard hollow core inner hole (AA) (relatively high cost, not commonly used)
③ Electrical discharge machining (EDM) process AA & A grade material + hollow core inner hole grinding (hollow core inner hole grinding grade ▼▼& ▼▼▼▼Different cost for different grade) (A&AA) (high cost, not commonly used)
④ Deep hole drilling AA&A grade material hollow core inner hole (limited by the ratio of the inner hole diameter & hole depth, conventional inner hole diameter x hole depth (30~40) times approximately) (B) (low cost, but requires batch processing)
⑤ Electrical discharge machining (EDM) processing AA & A grade raw material hollow core inner hole, the inner hole is relatively rough (C) (low cost, regular stock)
