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。
