Further Studies on Tungsten Carbide Cutting Tool Fatigue Are Needed

Category: Tungsten's News

Published on 06 November 2014

Tungsten carbide cutting tool, with high intensity, abrasion resistance and hardness, is widely used in the cutting machining. However, the tungsten carbide cutting tool fatigue problem is one of the primary reasons that are restraining its growth.

Tungsten carbide cutting tool is normally used in bad working condition and has to suffer from cyclic loading, thermal cycling and corrosion. Tungsten carbide cutting tool fatigue is one main factor contributing to tool damage. The types of tool fatigue include mechanical fatigue, thermal fatigue, corrosion fatigue, etc. In mechanical fatigue, tools suffer from alternating tension and compression as well as impact under cyclic loading and finally produce fatigue crack even if the mechanical stress has not yet reached the limit of tungsten carbide’s intensity. In thermal fatigue, the tungsten carbide cutting tool, interacting with its environment, surfers from thermal cycling, which results in its Internal energy changing and finally the tool material will produce crack source which can expand to microcracks. In corrosion fatigue, the components interact with the corrosion medium in the environment when used and caused crack or break. However, in is in fact that these types of fatigues are interacting at the same time during the actual applications of tungsten carbide cutting tools.

Currently, the reports about tungsten carbide cutting tools intensity account for a great majority, while researches about its toughness and fatigue property are few. In order to improve the core competitiveness in the international market especially the high-end product area, China should carry out further researches on the tungsten carbide cutting tool fatigue problem.

Tungsten Carbide Cutting Tool Technology Promotes Chinese Tungsten Industry

Category: Tungsten's News

Published on 05 November 2014

Tungsten carbide cutting tool’s main component is tungsten, and it is the most widely used end product in the industry chain of tungsten materials. Because its technological level directly reflects that of the tungsten industry in China and therefore is essential for whether China can turn from a country with large tungsten resources into a country with high tungsten related technology. Acknowledged by the rest of the world, China is rich in tungsten resources and ranks first around the world in tungsten resources, output, export and consumption. However, the advantage of rich tungsten resources has still far from being transformed into industrial advantage. The shortages of domestic tungsten industry, compared with the tungsten industry abroad, lie in: (1) the overall backwardness in technical equipment; (2) the weakness of independent innovation capability; (3) the oversupply of low-end and regular carbide cutting tool products and insufficient supply and technological reserve of high-end and high-property carbide cutting tools; (4) the dissociation between tungsten carbide material production and tungsten carbide cutting tool production, which has restrained the further development of high-end tungsten carbide cutting tools.

The above mentioned shortages are failed to be solved, so that currently, the supply of high-property tungsten carbide materials and high-end tungsten carbide cutting tools lies in the hands of some developed countries like America, Japan, etc. China then has to spend over 1 billion dollars to import those high-end products like tungsten carbide cutting tools each year. This kind of state of affair is extremely inconsistent with China’s status as a country with the most tungsten resources. China has to accelerate the development in tungsten powder material, high-property tungsten carbide material and cutting tool design, etc., and foster the technical and industrial advantages in the key links of tungsten industry, only by which can China’s tungsten carbide material, cutting tool technology and product quality be improved significantly and thus help China to turn from a country with large tungsten resources into a country with high tungsten related technology.

Tungsten Carbide Cutting Tool Industry in China Faces Talent Shortage

Category: Tungsten's News

Published on 05 November 2014

Tungsten carbide cutting tool industry has been through over ten years’ rapid development in China, but now, it meets its bottleneck. There are quite a number of difficulties in the current cutting tool industry, and the best solution to these problems would lie in the establishment of a high-quality talent team.

The modern cutting technology develops on the basis of material science, equipment manufacturing technology, information technology, etc. The professional areas it covers have exceeded the category of the traditional cutting technology profession. Therefore, the restructuring of professional talents is also required. Due to the importance of tungsten carbide cutting tool material and its coating technology, new professions and talents should be introduced accordingly.

In addition, because there are no longer metal cutting and cutting tool majors in undergraduate colleges, the majority of college students newly introduced lack cutting technique and basic cutting tool knowledge which are essential to people who engaged in this industry, like cutting tool designers and developers, material developers, coating grade developers and even salesmen. They all should be able to analyze the existing problems, improvement areas and innovation prospects by using all of this knowledge.

A group of inter-disciplinary talents of tungsten carbide cutting tool industry is vital to the development of the whole tungsten carbide cutting industry. With the transformation of enterprises, anther group of talents of field service with certain cutting technology knowledge should also be cultivated to be the technological support for salesmen.

Tungsten Carbide Cutting Tool Market in China Still Needs Improvement

Category: Tungsten's News

Published on 05 November 2014

Tungsten carbide cutting tool output in China maintains a sustainable growth, which places tungsten carbide cutting tools in a dominant position among various kinds of cutting tools. However, from the current situation in Chinese market, the domestic market share of tungsten carbide cutting tools is still lower that of the import ones. Therefore, the adjustment of the industrial structure is extremely urgent.

There are three main reasons that can account for the lower market share of the homemade tungsten carbide cutting tools:

I. Some manufacturers of tungsten carbide cutting tools in China lack enough quality awareness.

II. Many tungsten carbide cutting tool companies abroad provide thoughtful service including selecting, transporting, adjusting and replacing cutting tools for customers, which is neglected by the majority of manufacturers in China.

III. Some tungsten carbide cutting tool factories still remain the kind of production mode of individual workshop with low technological level and are always poorly equipped, which can not ensure the product quality.

From the current situation, tungsten carbide material has been in the dominant position among various kinds of cutting tool materials because it has better properties and higher cutting efficiency. However, if the tungsten carbide cutting tool enterprises want to achieve further and better development, they need to make industrial structure adjustment as soon as possible and accelerate the construction of production bases.

This week tungsten market continued weak demand for end mills has also been reduced, less demand for tungsten, iron, tungsten, iron manufacturers generally take the goods difficult, most manufacturers have cut tungsten iron / discontinued operation. Despite the low operating rate ferrotungsten market, but very poor end demand, the market is still an oversupply of tungsten iron, lack of effective support strong prices this week, the mainstream market quotations ferrotungsten relatively small decline last week.

Last weekend tungsten and molybdenum export quota news, traders mentality ferrotungsten slightly active, but because this year the quota has not been exhausted, the tariff policy in 2015 has not yet been introduced, so the temporary multi ferrotungsten businesses wait and see, temporary changes in export markets not. It is understood that last week 70 ferrotungsten offer mainstream acceptance concentrated in 16.8-16.9 yuan / ton, now 70 ferrotungsten offer mainstream acceptance concentrated in 16.7-16.8 yuan / ton.
