In benchtop wire edm machine, reciprocating wire walking is different from one-way wire walking. For slow wire walking, the maximum processing efficiency is a value. Under the premise of not burning the electrode wire, the maximum processing efficiency is obtained. This is the single-use advantage of the electrode wire; The electrode wire of the wire cutting machine tool is used in a reciprocating cycle, and the continuity of recycling has to be considered, so the cutting efficiency should be a relative value; It is meaningless to talk about the maximum cutting efficiency regardless of any consequences for the middle wire cutting machine. The cutting efficiency of the wire cutting machine should be a relative value, or it is more scientific to evaluate with efficiency plus life, and should be marked as: tolerance value/time.

The degree of molybdenum wire assistance of benchtop wire edm machine. If the molybdenum wire is installed too loosely, the molybdenum wire jitter can not only cause broken wire, but also directly affect the surface roughness of the workpiece due to the jitter of the molybdenum wire. But molybdenum wire can not be installed too tight, too tight the increase of internal stress, will also cause broken wire, so molybdenum wire in the cutting process, the degree of tightness should be appropriate, the newly installed molybdenum wire, should first tighten wire rework tight wire effort is not too large. Molybdenum filaments are treated after a while because they are stretched and loose. When the elongation is large, the vibration of the molybdenum wire will be intensified or the molybdenum wire will overlap on the wire cylinder. Instability and career causes the phenomenon of broken threads.

Always check the support degree of the molybdenum wire in the benchtop wire edm machine. If there is slack, it must be tightened. Molybdenum wire installation in accordance with the provisions of this law molybdenum wire to the cylinder two ends and fixed. The silk is generally stored in the wire cylinder at each end of the stay 10 mm, the overlap between the width, all less than half the length, so as to avoid the motor to reverse the cylinder line, make the part frequent, prevent damage, speed up the molybdenum wire cutting and breaking frequent. In the machine tool molybdenum wire lead block silk great, silk is made of two great ruby blocks of the root wire, guide pillar for the guide roller so rolling motion, because they are directly in contact with the molybdenum wire sliding friction. Therefore, the use of cylinder wear and molybdenum wire contact quickly quickly place can form a large deep ditch, must check in time, and then replace, otherwise there will be overlapping wire broken.
