The "intermediate wire feed" in the medium wire cutting machine refers to the composite wire cutting machine, that is, the principle of wire feeding is to use high-speed wire feed for rough machining and low-speed wire feed for finishing, and the processing quality can be between high-speed wire machines and low-speed wire machines between wire machines.

  In order to ensure the normal operation of the wire cutting machine, the following conditions need to be met, namely:

  1.It is necessary to insist that there must be a gap between the processing appearance of the molybdenum wire and the workpiece, and the width of the gap is determined by the processing conditions such as the working voltage and the processing amount.

  2.When processing wire cutting machine tools, it needs to be carried out in a liquid medium with a certain insulating function. The higher insulation requirements are to facilitate the generation of pulsed spark discharges, and no electric spark discharges can occur. Otherwise, it will only form a short-circuit connection.

  In practical applications, after the wire-feeding machine tool has been running for two to three months, its guide pulley and bearing should be replaced. If the machining accuracy is relatively high, if repeated cutting is required, it is necessary to judge whether to replace it from the vibration of the electrode wire. The wire cutting machine will be equipped with an oil cup, and the conductive wheel and wire wheel of the machine also need to be cleaned, but wiped with kerosene, do not wash after wiping, and must not be left in the sink.

  In the process of online cutting application, the user should operate according to the relevant operation methods, during which:

  1.Turn on the main power of the machine tool, the manipulator switch, and the 24V stepper drive power switch and high pulse power switch.

  2.Calculate the coordinate point programming program according to the drawing scale and the actual situation of the workpiece, pay attention to the clamping method of the workpiece and the diameter of the molybdenum wire, and select a reasonable cutting direction.

  3.After the processing is completed, turn off the high-frequency pulse switch, water pump switch, and coarse closing valve switch of the machine tool. If you want to brake and shut down, just press the red button of the main power switch. .

  4.Put the coarse adjustment switch in the valid position, unplug the feed switch, and further adjust the fine adjustment switch and software fine adjustment during the processing, so that the wire-feeding machine can be adjusted to a stable processing state.
