7 points that must be read when purchasing wire-cutting machine tools

1. Cutting accuracy: no need to spend pen and ink, everyone knows that it is very important, of course, the higher the accuracy, the better.

2. Cutting finish: The general finish is below 1.5um, as long as no line marks can be seen.

3. Whether there is a knife line mark on the hanging table: This is very important for the middle wire, which directly affects the use effect of the cut product. For example, when the metal die punches the plate with a thickness of less than 0.5mm, there are obvious burrs. If it is a plastic mold, it will leak glue, causing the mold to be scrapped! Most of the intermediate wires on the market cannot meet this requirement due to the defective electrical cabinet design, so please compare carefully when purchasing! Avoid causing huge losses to you. Due to the poor structural stability of the general machine, the body has not undergone aging treatment, and even the tempering process has been omitted.
4. Whether the smoothness in the X and Y directions is consistent: The Y direction is obviously worse than the X direction, and the desired effect cannot be achieved, thus affecting the cutting accuracy.

5. Whether the surface finish of the cutting taper is consistent with the straight face: This has little effect on the blanking of metal molds, but it is especially important for plastic molds!

6. Whether the wire should be tightened frequently during the operation of the medium wire cutting machine: This is very important for the consistency of accuracy, because the tightness of the molybdenum wire is different, the size of the cut is different, and the finish is also very different. It takes several times for a pair of molds to cut the wire, and the precision of the cutting can be imagined.

7. Whether the electrical part of the wire cutting machine tool is designed separately from the machine tool: This has a great impact on the service life of the machine tool. Because the working environment of the wire cutting machine is very harsh, the corrosiveness of the working fluid is relatively strong, and the machine tool is easy to enter water. , so that the electrical failure rate is not high, and the electrical is easy to age.
