Abstract

The invention discloses a numerical control wire-cutting fluid feeding method and a fluid feeding device; when wire-cutting machining is carried out on a workpiece, working fluid is enabled to spray to a molybdenum wire machining area all the time along a gap space machined on the workpiece; an included angle between a spraying direction of the working fluid and a molybdenum wire is N which is greater than 0 degree and less than 90 degrees. According to the method and the device disclosed by the invention, the cut gap space is utilized skillfully and a large-volume fluid feeding channel is formed between the machined molybdenum wire and a nozzle, so the fluid feeding amount of the channel is expanded timely and effectively, the fluid resistance of a working fluid discharge channel is reduced, the fluid exchange capacity in the molybdenum wire machining area is obviously improved, the problems of secondary discharge or short circuit and the like due to poor chip removal are prevented, and the wire-cutting machining efficiency and quality are ensured.

Description

technical field

[0001] The invention belongs to the technical field of wire cutting, and in particular relates to a liquid feeding method and a liquid feeding device for digitally controlled wire cutting. Background technique

[0002] Wire cutting process is to use continuously moving thin metal wire as electrode to perform pulse spark discharge on the workpiece to etch metal or cut into shape. This equipment is mainly used for processing superhard steel, hard alloy, various complex and precise workpieces. . Electrode wire is a thin metal wire (usually called molybdenum wire) made of precious metals such as molybdenum. The molybdenum wire discharges with the workpiece through the working fluid medium (emulsion, electrolyte, etc.), and corrodes the metal to achieve the purpose of cutting and forming. .

[0003] In recent years, with the continuous development of automation technology, various CNC wire cutting equipment has gradually become popular in the electrical processi...
