空芯配件、中空器械

医用工具及配件系列（空芯配件、中空器械）

依圆依样尺寸公差要求可生产特殊、复合、异型、超大超细超长组合成型的系列刀具。（可分不同等级的材料与研磨进行加工）

A:

材料等级:

①超高防锈高耐磨不锈钢系列(AA)(HRC54°±2°断面)(常规常备)

②.常规标准防锈高耐磨及超高耐磨不锈钢系列(A)(HRC45°~64°断面系列）

B:

空芯内孔加工等级(与材料等级和刃口加工等级无关)：

① AAA级:    带孔原生料+纯镜面空芯内孔研磨 (空芯内孔▼▼▼▼ &R0.01)(AAA) (成本很高,不常用)

② AA级:   带孔原生料,CFDA标准常规空芯内孔(AA)(成本较高,不常用)

③ 电火花EDM加工AA&A级料+空芯内孔研磨 (空芯内孔研磨等级▼▼&▼▼▼等级不同，成本也不同）（A&AA)(成本高,不常用)

④ 深孔钻打孔AA&A级料空芯内孔(受限于内孔径与孔深度的比例,常规内孔径x（40～60）倍左右的孔深度）（B）（成本低，但需批量加工）(常规常备)

⑤ 电火花EDM加工AA&A级料空芯内孔,内孔相对粗糙些（C）（成本低，常规常备）

Medical tools and parts series

(hollow core fittings, hollow instruments)

We can produce special, compound,special-shaped,super-large,

super-thin/super-long combined profile series tooling according to requirements of drawings,samples and dimension tolerance.

(We can do process with different grades of material and grinding)

A:

material:

①Super-high anti-rust high wear resistance stainless steel series(AA)

   (HRC54°±2°Section)(regularly stock)

②General 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):

①AAA 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 (40~60) times approximately) (B) (low cost, but requires batch processing)(regular stock)

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)
