The wire conveying system of the wire cutting machine will have a serious impact on the brightness of the workpiece. If there is a problem with the wire transfer system of your wire EDM, then you need to stop testing and repair the system. The brightness of line cutting is generally determined by two factors, one is the size of the pits removed by a single discharge, and the other is the concave and convex stripes formed by the commutation. This is an important element that affects brightness. The control of the size of the pits formed by a single discharge is relatively simple, and it is only necessary to reduce the energy of a single pulse. It's just that the energy of a single pulse is too small to cut thicker workpieces. This is similar to the precision rules in EDM, resulting in unstable working conditions, extremely low efficiency, and poor chip evacuation.

  When the wire cutting machine is cutting the specimen, the feed speed can be adjusted according to the hardness of the rock before work. During the cutting process, adjusting the feed speed may cause knife marks. According to the experience of cutting harder stones, the speed is generally around 40 mm/min. When working, start the main motor first, and then press the work key. When starting to cut, the cutting speed should be slow at this time because the rock is often irregular in shape. Once the blades have all entered the rock sample, the speed can be faster. When clamping irregular rock, it can be clamped by top pressure method. When cutting core samples, if there are many rocks, the attached long pressing plate can be used to press several rock samples together and cut them together to improve work efficiency. Turn on the power, press the button of the host, whether the blade rotation can be different from the direction of the arrow. The cutting machine automatically advances and retreats the knife. When the cutter moves to the end along the table, it can automatically return to the starting point and automatically stop moving.

  After the wire EDM is completed, turn on the power to check whether the various parts of the machine can be rotated sensitively and whether the fasteners can be loosened. The idler bearing should be injected with kerosene 1-2 times a week to maintain cleanliness and service life. Pay special attention to the careful maintenance of the console installation and insist on cleaning. Operators must not interfere with electrical components and console installation. If a problem is found, the operator should stop the machine immediately and notify the maintenance personnel to overhaul.
