How to calibrate the perpendicularity of molybdenum wires for WEDM machines?

Sometimes friends will meet the wire cutting molybdenum wire machine barrel, that is, the storage barrel of the molybdenum wire run off, the phenomenon of pressure wire stacked wire, and even their own speculation may be the barrel rod or bearing problems, dismantling a quite troublesome and difficult to install ...... We will talk about this today, the wire cutting machine barrel appear molybdenum wire pressure wire stacked wire, where to start! Solution.

Generally speaking, to solve the problem of wire cutting machine barrel molybdenum wire pressure wire stacking, should start from the following five places. 1:

1. Use the table to see if the molybdenum wire storage cylinder is concentric, to determine whether there is any problem with the cylinder shaft and bearings;

2. how loose or tight the molybdenum wire is, it is too loose to stack the wire;

3. the rear guide wheel or the back of the silk bar or wire head is not pressed, or wire head wire is not wound well. 4;

4. the above 3 points to determine the problem, basically can view the guide wheel bearings are bad, the guide wheel left and right fluctuations, be sure to replace!

In practice, we correct the perpendicularity of the wire cutting machine molybdenum wire method generally has two ways.

In practice, a simple way is to use the calibrator to correct the verticality of the molybdenum wire, if there is no calibrator then how to do? There is another way is to find a positive block can be spark method to find the right, molybdenum wire manufacturers with a brief introduction to this way how to correct.

Generally find the right block is to find a hexagonal workpiece, no hexagonal workpiece, then you can find a similar almost, when we correct the verticality of the wire cutting machine molybdenum wire, start their own visual inspection of the wire cutting machine molybdenum wire is vertical, if the tilt is strong, then you can adjust the UV axis of the EDM wire cutting machine to make the molybdenum wire is roughly perpendicular to the wire cutting machine workbench.

The second step is to find the hexagonal workpiece on the wire cutting machine table, so that the molybdenum wire along the direction of the X-axis movement, until the molybdenum wire touches the positive block of the time will produce a spark discharge, and then you can look at the surface of the workpiece to see if the spark discharge is uniform, if the spark is uniform, it is shown that the verticality of the molybdenum wire wire cutting machine is not a problem. If there are more sparks at the lower end of the hexagonal workpiece, then the molybdenum wire of the WEDM machine is deviated to the right, in this case, you can adjust the value of U-axis of the WEDM machine a little bit smaller, and keep it until the upper and lower sparks of the positive block are even. If it is more sparks at the upper end, then adjust the value of U-axis of the WEDM machine a little bit larger, until the positive block of the upper and lower sparks are uniform, the same reason to adjust the V-axis of the WEDM machine, until the positive block of the upper and lower sparks are uniform. In this way, the perpendicularity of the molybdenum wire of the WEDM machine will be no problem.
