Filters for Cutting Wires (Applicable manufacturer: Mitsubishi Electric Corporation)
Filters for wire cutting are parts used with hot wire cutting machines. When performing wire cutting, the object to be cut is constantly submerged in a machining fluid such as water or oil. That machining fluid is supplied to a machining tub by a machining fluid supplier, and filters remove machining particles in the fluid. Durability is demanded for filters, and there are anti-rust treated filters, stainless steel types, resin types, and more. Thermosetting resin and specially folded high-performance paper are used for the filter paper, which not only reduces the contamination generated during initial filtering, but also eliminates the internal imbalance of water to achieve long lifespan. Secondary discharge is prevented and improvements in performance such as maintaining clean tank transparency and increasing the lifespan of ion exchange resin can also be expected.
