JR teaches you to buy a high price - cost medium - walk silk - wire cutting machine. The specific selection criteria can refer to the following points:

 

1, finish cutting: do not see the line as the standard, the general smoothness below 1.5um.

 

2, cutting precision: no charge, everyone knows very important, of course, the higher the accuracy is better.

 

3, X, Y direction of smooth finish is consistent: Y direction is obviously less than the direction of X, can not reach the ideal effect, thereby affecting the precision of cutting.

 

4, cutting taper surface finish is consistent with the direct surface: This is not much impact on the metal mold cutting blanking to avoid empty, but it is particularly important to the plastic mold!

 

5, in the wire electrical part whether the machine and machine tool designed separately cutting: there is a lot of influence on the service life of this machine, the cutting work environment is very bad, corrosive liquid is relatively strong, and easy to machine in water, so that the electrical failure rate high, easy electrical aging.

 

6, WEDM operation process whether or not to frequent wire tensioning: this consistency of accuracy is very important, because the tightness of the molybdenum wire, cutting out the size is not the same, finish also have a big gap, if a few Cisi matter die cutting, cut out the precision as can be imagined.

 

7, whether the knife hanging Taiwan line: at this point to go wire is critical, cut out directly affects the use effect of the product, such as metal stamping plate thickness below 0.5mm, there are obvious burrs, such as plastic mold will lead to leakage of plastic, mold scrapped! On the market to take the wire in the most because the electric cabinet design defects and can not meet the requirements, so choose carefully to avoid is compared! Bring huge loss to you. Due to the poor stability of the fuselage structure, the body is not aging, even the tempering process has been saved. The stability of molybdenum wire operation is not good, which will cause the X and Y shaft's finish is not consistent.
