Diamond segment research project

There are many diamond segment research projects.Mainly to improve the strength of diamond, improve the quality of segment and production efficiency.There is also an aspect of improving the applicability of the segment.This article introduces the research projects of diamond segment, so that everyone can better understand the production process of diamond segments and scientific research projects. The most common research and development categories are as follows:

1. R&D and innovation of diamond titanium plating project

The diamond powder is at the forefront of the production process, and the prepared diamond powder is passed through titanium plating technology, through physical and chemical reactions, so that a layer of titanium film is formed on the surface of the diamond.At present, the common titanium plating technology is to plate the liquefied titanium element on the surface of the diamond by physically shaking the diamond in a vacuum environment.However, the film structure of this titanium plating method is not stable enough.Some manufacturers began to use vacuum brazing equipment for titanium plating, which greatly improved the holding power of diamond.In the actual application process, the service life of the ordinary diamond segment is increased by about 5-15%. Of course, with the continuous development of titanium plating technology and even the technology of plating other metals, the holding power of diamond will be further improved.

2. Powder ratio research and development

Powder ratio research and development is almost a must-have ability for large diamond segment manufacturers.Through the differentiated ratio of powder, the segment has different cutting performance to meet the different needs of different customers for products.For example, customer A needs segments with low price, good wear resistance, moderate sharpness and high hardness for cutting stone.According to the customer's requirements, the product is designed, and finally a relatively reasonable formula will be produced according to the customer's needs.A metal will also have a specific metal ratio, and even diamond concentration and particle size requirements.

The purpose of powder ratio is mainly to carry out individual design according to customer requirements, which may be closer to the needs of individual customers.For the mainstream segment products on the market, the adjustment of the powder ratio is more based on the actual performance of the overall market.Therefore, in order to change the formula of general mainstream diamond segment products, it is necessary to conduct large-scale testing of the products, summarize data, propose improvement plans, and continue large-scale testing.The data is then aggregated and the process continues until the new formulation fully meets expectations before replacing the old product.It is not so much the research and development of powders that it is the end result of extensive testing feedback. But this work needs to be sustained over the long term.

3. Research and development and improvement of segment production process

There are many ways to develop recipes. Most of the diamond segment manufacturers currently conduct compositional analysis on the relatively high-quality segments on the market. However, the composition analysis does not mean that the exact same segments products can be produced completely, because the production process of the segments determines the quality of the segment, so where is the research and development of the segment process?

1: The segment cold pressing mold: The size and specification of the cold-pressing die determine the density of the segment, as well as the life and wear resistance of the segments.

2: The segment hot pressing mold: The size of the hot-pressing mold depends on the cold-pressed volume of the metal powder and the thickness of the segment iron sheet. The thicker the thickness of the hot-pressing mold, the less the number of sintering, which reduces the production efficiency and increases the raw material cost of the segment.

3: The temperature of the segment sintering: The sintering temperature of the segment has a great relationship with the material of the matrix bond. The lower the melting point of the bonding material and the main base material in the carcass material, the lower the sintering temperature will be required, and vice versa.

4: The pressure for the sintering of the segment: The sintering pressure of the segment depends on the required density of the segment. The higher the density requirement, the higher the sintering pressure.

5: Duration of segment sintering and pressure holding: Generally speaking, the sintering time is kept at 8-10 minutes, but the specific time must be determined according to the actual situation.

4. Research and development of automatic production of segment

At present, under the condition that mechanization is slowly mature, the process of automation of diamond segments in the future is not too far away. In particular, the series of processes from stirring to cold pressing, cold pressing to moulding, moulding to hot pressing can be automated. Some manufacturers have already adopted it, and the full automation of segment products will gradually come in the future.

The research and development of the segment also includes the research and development of the ratio of diamond particle size, diamond particles and diamond concentration. It is foreseeable that in the future, the development of diamond segments will continue to move forward, moving towards a better and faster development direction.
