Problems solved by technology

The abrasive particle size is small, and it is mostly used in grinding, and through the analysis of relevant data, it is believed that although this kind of tool has a certain chemical reaction on the surface of the abrasive, the combination of the abrasive and the matrix has a certain brazing effect, but the exposure of the abrasive , The holding strength of abrasive grains, multi-layer grinding performance and other aspects still

Embodiment 1

[0051] Now a multi-layer brazing grinding disc is needed to grind the surface of metal materials. The size of the grinding disc is 125mm, and it is formed by producing 10 multi-layer brazing blanks with length × width × height = 40mm × 10mm × 4mm and then brazing through a vacuum brazing furnace. Production steps:

[0052] The first step is to determine that the dilution material is Al 2 o 3 Particles, the particle size is 120 mesh, the brazing solder is copper-based solder, its composition is copper-tin-titanium, the content percentage is: copper 60%-65%, tin 19%-24%, titanium 16%-26%, nickel 1~3%. The particle size is 120 mesh. The diamond abrasive is artificial diamond, the grade is high-grade wear-resistant type, and the particle size is 40 / 50 mesh. The diluted material and brazing solder are compounded into a composite material at a volume ratio of 1:2.

[0053] The second step is to granulate and wrap the diamond abrasive grains. The composition of the wrapping is ...

Abstract

The invention discloses a novel diamond tool production technology. The production technology comprises the following steps that firstly, diluted materials and welding flux are mixed into composite materials; secondly, diamond grinding particles are subjected to granulating and wrapping, and bonding and fixing are conducted through an acetone bonding agent; thirdly, a wrapped diamond grinding material composite body is evenly mixed with filling materials, brazing welding flux and the acetone bonding agent; fourthly, the mixture is added in a die to be pressurized and sized; and fifthly, a formed blank block is heated and subjected to brazing. According to the technology, the brazing strength of single grinding particles is indirectly controlled according to the size of the brazing diamondgrinding material brazing area, through filling material structure matching, multi-layer continuous machining performance of multi-layer brazing is achieved, and the service life of a brazing diamondgrinding material tool is prolonged; and the production technology is simple, the quality is stable and easy to control, the procedure can be standard, and the novel diamond tool production technologyis suitable for industrial batched production.

Description

technical field [0001] The invention relates to a production process of a novel diamond tool. Background technique [0002] The traditional diamond abrasive tools represented by diamond tools can be divided into two categories: electroplated tools and sintered tools, each of which has its own strengths. However, due to the high surface energy of the diamond surface, it is difficult to infiltrate with common metals, and there is no firm metallurgical bonding layer at the interface between the abrasive grains and the matrix metal. The carcass has a small holding force on the abrasive grains, and the abrasive grains are easy to fall off due to the wear of the carcass, and the utilization rate is not high; on the other hand, because the diamond particles are mechanically embedded, the exposed height is small, and the cutting efficiency not tall. [0003] A new generation of brazed diamond tools is produced by welding diamond abrasives and workpiece substrates together by melti...
