Description

Technical Field

[0001] This utility model relates to the field of multi-wire cutting machine technology, specifically to a filtration and cooling device for circulating cutting fluid in multi-wire cutting machines. Background Technology

[0002] A multi-wire cutting machine is a device used for cutting hard materials. Its working principle is to use the high-speed reciprocating motion of metal wires to bring abrasive into the processing area of ​​the material to be cut for grinding, and to cut the material into hundreds or thousands of thin slices at the same time.

[0003] In addition to the combination of metal wire and abrasive, multi-wire cutting machines can also use a combination of diamond wire and cutting fluid. The diamond wire moves at high speed to cut the material, while the cutting fluid acts as a coolant, carrying away the heat and impurities generated during cutting and returning them to the abrasive tank. To achieve the recycling of the cutting fluid, debris and impurities in the cutting fluid must be removed. Furthermore, the cutting accuracy of the workpiece is affected by changes in the temperature of the cutting fluid. The greater the temperature change of the cutting fluid, the lower the cutting accuracy of the workpiece. Therefore, constant temperature control of the cutting fluid is also necessary.
