Development of ultra precision turning of diamond tools

July 26, 2022

Nowadays, with the development of science and technology, precision machining can no longer meet the needs of people, and more and more enterprises begin to study ultra precision machining. Ultra precision turning of diamond tools is mainly used to process soft metal materials, such as non-ferrous metals such as copper and aluminum, some alloys and non-metallic materials, and has achieved good results in practical applications. Therefore, the development prospect of diamond tools is very broad.

Advantages and development of ultra precision turning of diamond tools
1. Develop towards higher precision, high efficiency and large scale
Large optical lenses are essential in various technical fields, such as laser and fusion, synchrotron radiation technology, and the research and development of large astronomical telescopes. Therefore, the workpiece requiring ultra precision turning is gradually larger, and the requirements for machining accuracy are also increasing. With the stability of ultra precision machining quality and the sharp increase in the number of ultra precision machining parts, foreign ultra precision turning machines are developing towards high efficiency. Improving productivity generally starts from two aspects: increasing spindle speed and feed speed, and shortening spindle start and stop time.

2. Adopt computer compensation technology to improve machining accuracy
All kinds of relevant parameters that lead to the decline of machining accuracy are measured in advance. Through calculation, processing and compensation, the accuracy higher than that of machine tools can be obtained. This development trend has been paid more and more attention. Because it is limited to improve the machining accuracy only by improving the accuracy of reference components. For example, the guideway straightness of some ultra precision machine tools has reached 0.025/1000000, and it is difficult to improve its accuracy. Computer compensation is needed to solve the problem.

3. Integration of processing and measurement
The components of ultra precision machining machine tools have high accuracy. If some appropriate instruments are configured or certain measures are taken, they can be used as measuring devices. In this way, processing and measurement can be combined, so that processing and measurement can be carried out at the same time, and processing can be carried out under monitoring conditions, so as to realize the integration of processing and measurement and improve economic benefits.

4. Developing modular ultra precision lathe
Using different ultra precision machine tool elements and components to form various types of ultra precision lathes is conducive to reducing costs and shortening the manufacturing cycle. Users can put forward requirements according to needs, and obtain the required machine tools at a lower price and in a shorter time.

Shortcomings of ultra precision turning of diamond tools
However, in ultra precision machining, diamond tools can not process every material. For ultra precision cutting of ferrous metals, diamond tools are not so perfect. Because the diamond turning tool wears fast in the cutting process, which destroys the stability of the machining process, it can not guarantee that the machined parts have ideal surface roughness and geometric accuracy.
It is generally believed that natural diamond turning tools are not suitable for ultra precision cutting of ferrous metals, but in actual production, there are some steel and other difficult to machine material parts with complex shapes and high precision requirements. Therefore, in recent years, people began to study the ultra precision turning of diamond in brown metals.

No gold is enough, no man is perfect, and so is diamond cutter. Although the performance of refined steel stone tools in ultra precision machining is excellent, they can not be processed in all metals. Therefore, people are constantly studying and discussing how to apply the performance of diamond in ultra precision machining to all metals.
