Composite conductive cutting sheet

Abstract

The present invention relates to metal cutting material, and is especially one composite conductive cutting sheet. The technological scheme is that conducting material is added into the cutting material to make the cutting sheet become a conductor. Specially, the cutting sheet for alloy has added conducting material comprising metal powder and RE material in the weight ratio of 10 to 0.5-1.5; and the cutting sheet for diamond has added conducting material comprising metal powder, metal binder, conducting paste and RE material and in the added amount of 5-15 %. The composite conductive cutting sheet has excellent conducting performance, and during cutting with the composite conductive cutting sheet, certain pulse voltage is applied to produce current and make the cutting become thermal cutting with electrochemical reaction. The present invention can increase the service life of the cutting sheet by decade times and raise the cutting efficiency greatly.

Description

Technical field [0001] The invention relates to a metal cutting material, in particular to a composite conductive cutting sheet used for metal cutting and grinding. Background technique [0002] The metal cutting discs or grinding wheel discs currently used are mainly divided into alloys and diamonds. These two types of cutting discs do not have electrical conductivity. When used for metal cutting, they completely rely on thermophysical cutting and consume during the cutting process. A large number of cutting chips results in low cutting efficiency and high consumption of cutting chips. Summary of the invention [0003] The purpose of the present invention is to provide a composite conductive cutting sheet in view of the defects in the prior art. By using the current discharge effect between the composite conductive cutting sheet and the metal material to be cut, the cutting efficiency can be greatly improved, and the cutting efficiency can be greatly reduced. The loss of the fi...
