Why is it easy to break molybdenum wire in stainless steel processed by wire cutting process?

The stainless steel material is a bit like tungsten steel, which is not easy to be electrocorroded, and it is a bit like white steel, and the spark is very large. Sacrificing some speed, adjusting the current to be smaller and more stable, it is still easy to cut, because this material is relatively pure.

What grade? I don't always break the wire when I cut pure tungsten! Don't always come down to the material!

First make sure that the operation is okay, then the molybdenum wire, and then the machine. Of course, this is the result of cutting ordinary materials! If it is really a material problem, you can consult the manufacturer's maintenance personnel.

Because sometimes it's hard to tell! Maybe your material is deformed and pinched!

Generally, tungsten and molybdenum alloy are used, molybdenum has high tensile strength and good toughness, while tungsten can withstand high temperature and has good conductivity. The combination of the two can meet the needs of wire cutting!

Wire cutting special molybdenum wire GMPM-1, GMHI M-2 is used for cutting and processing of various non-ferrous metals, steel and magnetic materials. It has the characteristics of high strength, good discharge performance, high surface finish, cutting speed and long life.

Advantages of molybdenum wire::

1.The molybdenum wire has high precision, and the wire diameter tolerance is controlled within 0;

2.The incidence of wire breakage is low, the processing rate is high, and it is cost-effective;

3.Stable long-term continuous processing is possible.

Molybdenum wire is used for fast wire walking, and copper wire is used for slow wire walking.

The cut aluminum parts are easy to stick to the wire, if you use a magnifying glass to see the white spots on the silk one by one, the sticky will break the wire.

Reasonable collocation of pulsed electrical parameters.

When CNC high-speed wire EDM wire cutting processing, a wide pulse width is easy to produce relatively large alumina or alumina particles stuck on the surface, and small pulse intervals will also produce large particles. The electrode wire is very easy to adhere to these large processing particles, which has a great negative impact on the processing. By increasing the no-load voltage blessing value of the pulse current, reducing the pulse width, and increasing the pulse gap, the possibility of sticking to the electrode wire can be reduced.

2 Requirements for working fluids.

At present, the aqueous solution used as the working fluid for CNC high-speed wire EDM wire cutting processing, the conventional configuration is 1...10. The processing of aluminum material is to keep the working fluid clean and make it work effectively, and the sponge after use can avoid flowing into the water tank, keep the working fluid unobstructed and reduce adhesion. Sponges are changed regularly.

3 Tips.

A sponge can be added to the rear slot of the online rack, and the high-speed reciprocating electrode wire is rubbed by the sponge to reduce the jitter of the electrode wire and ensure the normal operation of the power supply.
