Diamond wire cutting machining equipment and cutting method of neodymium iron boron magnet

Abstract

The invention discloses diamond wire multi-wire cutting machining equipment. The diamond wire cutting machining equipment comprises a support, a pay-off roller assembly, a pay-off moment wheel assembly, a grooved roller frame, grooved rollers, a take-up moment wheel assembly, a take-up roller assembly, a workbench and a diamond wire. The grooved roller frame is supported by the support, and the two or more grooved rollers are arranged on the grooved roller frame in parallel. The workbench is installed below the grooved roller frame. A pay-off roller guide rail and a take-up roller guide rail are connected with the support, and the take-up roller assembly and the pay-off roller assembly are arranged on a pay-off conveying vehicle which does reciprocating motion along the take-up roller guide rail and the pay-off roller guide rail. One end of the diamond wire is wound on the pay-off roller, and the other end of the diamond wire is wound on the grooved rollers after passing through the pay-off moment wheel and then is wound on the take-up roller after passing through the take-up moment wheel. According to the diamond wire cutting machining equipment, the cutting wire with the surfaceplated with diamond micro-particles is adopted, it does not need to add abrasive materials any longer, the cutting quality is obviously changed, and the working environment is improved. The inventionfurther relates to a diamond wire cutting machining method of a neodymium iron boron magnet. The cutting quality is obviously changed, cutting liquid can be circularly used, and the environmental friendliness is facilitated.

Description

technical field [0001] The invention relates to a multi-wire cutting processing equipment and a cutting processing method, in particular to a diamond wire multi-wire cutting processing equipment and a cutting method for NdFeB magnets, which can also be used for cutting semiconductor materials and belong to special cutting processing equipment field. Background technique [0002] NdFeB rare earth permanent magnets are used more and more for their excellent magnetic properties, and are widely used in medical nuclear magnetic resonance imaging, computer hard drives, audio, mobile phones, etc.; with the requirements of energy saving and low-carbon economy, NdFeB rare earth permanent magnet materials have begun to be used in auto parts, household appliances, energy-saving and control motors, hybrid vehicles, wind power generation and other fields. [0003] Because NdFeB rare earth permanent magnet materials are brittle and hard, processing is very difficult, and ordinary process...

Problems solved by technology

Since the diamond wire can cut both the workpiece and the guide wheel group at the same time, reducing the number of guide wheels is a difficult problem to be solved. Patent CN 103963180A proposes a multi-wire cutting machine with six guide wheels, but it sti
