北京不銹鋼加工應(yīng)該注意那些問題

    北京圣恩斯特不銹鋼加工廠將為你提供我們最優(yōu)質(zhì)的服務(wù)。所以總結(jié)出來了以下的一些加工注意事項(xiàng)，希望能對(duì)廣大用戶能夠有所幫助。

1.不銹鋼加工轉(zhuǎn)速應(yīng)該慢點(diǎn),進(jìn)給率慢點(diǎn),一般線速不超過130.

2.焊縫缺陷：焊縫缺陷較嚴(yán)重，采用手工機(jī)械打磨處理方法來彌補(bǔ)，產(chǎn)生的打磨痕跡，造成表面不均勻，影響美觀。

3.冷卻液應(yīng)該用水溶性切削液,半合成的,冷卻、潤滑都好.

4.表面不一致：只對(duì)焊縫進(jìn)行酸洗鈍化，也造成表面不均勻，影響美觀。

5.不銹鋼雖然硬但是它也棉,就是軟的意思.上述的車法都會(huì)攪刀.要不銹鋼加工車刀要磨好.車刀正角要大于5這樣子吃刀量可以打好多,效率會(huì)高出來.一般持刀單邊3MM.

6.因?yàn)椴讳P鋼容易變形,鉆孔和攻螺紋很是困難,所以要防止過熱,在加工面噴油.

7.在不銹鋼焊接中應(yīng)該注意焊機(jī)電流的調(diào)節(jié)大小.

8.人為因素造成的劃傷比較嚴(yán)重：在吊裝、運(yùn)輸和結(jié)構(gòu)加工過程中，磕碰、拖拉、錘擊等人為因素造成的劃傷比較嚴(yán)重，使得表面處理難度加大，而且也是處理后產(chǎn)生銹蝕的主要原因。

9.打磨拋光鈍化不均勻：手工打磨拋光后進(jìn)行酸洗鈍化處理，對(duì)面積較大的工件，很難達(dá)到均勻一致處理效果，不能得理想的均勻表面。并且工時(shí)費(fèi)用，輔料費(fèi)用也較高。

10.因?yàn)樵诩庸さ倪^程中刀具表面與其他非金屬或者金屬結(jié)合成合金,使刀具更加容易生銹,我覺得可以給他加個(gè)防氧化膜或者抗氧化膜.

11.設(shè)備因素：在型材、板材卷彎、折彎過程中，造成的劃傷和折痕也是處理后產(chǎn)生銹蝕的主要原因。

12.劃痕難除去：整體酸洗鈍化，也不能將加工過程中產(chǎn)生的各種劃痕去掉，并且也不能去除由于劃傷、焊接飛濺而粘附在不銹鋼表面的碳鋼、飛濺等雜質(zhì)，導(dǎo)致在腐蝕介質(zhì)存在的條件下發(fā)生化學(xué)腐蝕或電化學(xué)腐蝕而生銹。

13.其他因素：不銹鋼原材料在采購、儲(chǔ)存過程中，由于吊裝、運(yùn)輸過程產(chǎn)生的磕碰和劃傷也比較嚴(yán)重，也是產(chǎn)生銹蝕的原因之一。

14.酸洗能力有限：酸洗鈍化膏并不是萬能的，對(duì)等離子切割、火焰切割而產(chǎn)和黑色氧化皮，較難除去。

以上的問題是我們?cè)谌粘＜庸さ倪^程中和用戶那里得到的反饋總結(jié)出來的。

Beijing Shengensite stainless steel processing will provide you with our best service. So summed up some of the following processing considerations, hoping to be able to help the majority of users.

1 stainless steel processing speed should be slow, slow feed rate, the general line speed does not exceed 130.

2 weld defects: the more serious defects in welds, using manual methods to compensate for mechanical polishing, grinding marks generated, resulting in uneven surface and affect appearance.

3 cooling fluid should be water-soluble cutting fluid, semi-synthetic, cooling, lubrication is good.

4 Surface inconsistent: only weld pickling passivation, but also caused uneven surface and affect appearance.

5 stainless steel although hard but it also cotton is soft meaning. Above method will stir car knife stainless steel processing tools to be sharpened. Turning positive angle is greater than 5 so that the child can play a lot of cut, efficiency high out general knife unilateral 3MM.

6 Because stainless steel is easy to deform, drilling and tapping is very difficult, so to prevent overheating, the machined surface injection.

7 It should be noted in welding stainless steel welding current regulation size.

8 scratches caused by human factors more serious: in the lifting, transportation and construction process, bump, drag, hammering scratches caused by human factors such as more serious, making the surface more difficult, but also rust after treatment the main reason.

9 passivation polished uneven: polished by hand after pickling passivation treatment on larger workpieces, it is difficult to achieve uniform treatment effect can not be satisfactory uniform surface. And work expenses, materials costs are also higher.

10, because in the course of processing the tool surface and other non-metallic or metal combined into alloys, the tool easier to rust, I think we can give him an anti-oxidation film or oxide film.

11 Equipment: In a profile, plate roll bending, bending process, causing scratches and creases are also the main reason for rust treatment.

12 is difficult to remove scratches: Overall acid passivation, nor can a variety generated during processing to remove scratches, and can not remove the scratches, welding spatter adhering to the surface of stainless steel and carbon steel, splash and other impurities , results in the presence of corrosive media chemical etching or electrochemical corrosion and rust.

13 Other factors: stainless steel raw materials procurement, storage process, due to lifting and transportation process produces more serious bump and scratches, but also one of the causes rust.

14 pickling capacity is limited: pickling and passivation paste is not a panacea for plasma cutting, flame cutting and productivity and black oxide, is more difficult to remove.

The above problems are in our daily course of processing and the user get feedback summed up.
