The Effect of the Verticality of Molybdenum Wire on the Machining of Wire Cutting Machine

The vertical of the wire-cut molybdenum wire refers to the perpendicularity between the molybdenum wire and the moving plane of the X and Y pallets. The influence of the perpendicularity of the wire on the machining accuracy is direct and significant. Correcting silk is a very cautious and serious work and must not be wasted.

In the purchase of wire cutting machine, it will bring tools for molybdenum wire correction, including sub-bell-shaped, cylindrical, rectangular, quadrihexahedron, there is a special instrument for conductive contact with the meter display. As long as there is sufficient accuracy and proper use, you can receive satisfactory results. No matter what kind of calibration tools seem to be simple, but the system is more troublesome, you must check the correction tools you get. Use benchmark comparisons, light transmission checks, practical transposition measurements, etc. The most convenient self-test is of course tetragonal hexahedron. Only the elements are placed on the bed of the machine tool, and the adjacent three faces are measured with the X and Y coordinates. The error value will be clear at a glance.

When calibrating molybdenum wire, most of them rely on positive methods except for special instruments that are displayed on the meter. This is the most intuitive and credible method. However, it should be noted that the top surface of the tool must first be measured and used in parallel with the X and Y planes. It should not be scribbled on the horn or the bed. This is often not reliable enough. Spark correction is performed in a state of no-current and small current. Generally, only one channel of power amplifier is used. Otherwise, the calibration tool will be quickly damaged. This spark correction is more accurate than spark-free conductive contact. If the spark is uniform on the observation surface not less than 50mm, the accuracy is usually within 0.01. Both horizontal and vertical directions should be alternately repeated twice. After being skilled and having several experiences, the corrected results will be credible and reliable, and it is certain that it can reach the verticality range that is compatible with the overall precision of WEDM.
