What processing methods are commonly used for medical stainless steel pipe fittings?

1 Flame cutting

Using gas cutting is almost impossible. The pipe port is sure to change color, chrome-nickel stainless steel, aluminum and aluminum alloy and other materials oxide melting point is higher than the melting point of the material itself, so basically can not be cut by oxygen cutting method.

Carbon arc gouging

Carbon arc gouging refers to the use of graphite rod or the arc between carbon rod and workpiece to melt the metal, and then blow it off with compressed air to realize the machining of grooves on the metal surface. Carbon arc has smoke, dust pollution and arc radiation. The inner wall with a large amount of molten cooling metal residue, difficult to remove.

3 wire cutting

The use of wire cutting fast wire can meet the notch quality requirements. However, it should be noted that the color will change after the pipe end is cut, which needs to be polished. Unbearably slow, small production can be considered. Outside processing, need not invest. Slow speed, small batch.

4 Grinding wheel cutting machine (with automatic steel tube end burr removal machine)

With ordinary grinding wheel cutting machine after cutting with burr and hanging edge flying, with the use of automatic stainless steel pipe end burr removal machine, can achieve very good use effect, low cost, but the grinding wheel consumption is a little big, suitable for small batch when used.

Automatic instrument lathe

Instrument lathe for cutting very thin wall of stainless steel tube (wall thickness 0.3~0.4mm), recommend the use of high-quality white steel or steel tool, although the purchase cost is higher, but more durable, the section is very smooth. This way is low degree of automation, labor intensity. The efficiency of automatic refit instrument lathes or automatic lathes is greatly improved, but the high-speed rotation of six-meter-long steel pipes will damage the thin-walled steel pipes
