Main problems of cemented carbide industry in China.

Main problems of cemented carbide industry in China: one is the enterprise on a smaller scale, the industrial concentration is not high. According to incomplete statistics, 199 cemented carbide enterprises average annual capacity of 176 tons, with average annual output of 86 tons, annual output over 1000 tons of only four companies. Second, less investment in science and technology, the lack of high-end technical personnel, technology research and development ability is weak. Cemented carbide industry in China in the field of science and technology investment is less than 3% of sales revenue, science and technology development level is not high, less original core technology achievements. Third, the low level of product quality, product structure need to be adjusted. China's cemented carbide production accounts for more than 40% of world output, but the carbide sales income is less than 20% of the world, mainly due to the high performance super fine alloy coating, high precision, high performance grinding blade, ultra hard tool materials, complex, precision carbide nc cutter large products less high value-added products production, deep processing and varieties of form a complete set is not complete.
Depending on our years experience of cemented carbide industry and our talented engineers and skillful workers, we always provide our customers the products with good quality, competitive price, fast turnaround and reliable after sales service.

Improve the quality and performance of PDC cutter tooth at four explanation

Improve the quality and performance of PDC cutter tooth at four explanation

Auger teeth is indispensable in many coal mine machinery parts and components, in many coal mining will encounter in the process of hard rock. Will greatly reduce the service life of cutter tooth and abrasion resistance, so how to avoid? This paper from four aspects to detail how to improve the service life of rock auger teeth and abrasion resistance and the strength and impact toughness and thermal stability?
Method one: use diamond enhanced cutter carbide teeth, combining parallel diamond compact producing method, design a special way of pyrophyllite chorus block assembly, after acid, alkali pretreatment of diamond micro powder (W20 W40 + + W5 +) in the binder according to certain proportion after mixing, the carbide substrate loading according to strengthen column tooth shape processing of graphite mould, and vacuum processing, and then load the wax stones, using hydraulic press. And after cutting tooth, on the wear resistance and service life have greatly improved.
Method 2: thermal stability composite polycrystalline diamond cut teeth, because of its high temperature rise for carbide, carbide hardness drop caused by the temperature rise, wear faster, so we can take the heat stability of composite polycrystalline diamond cut teeth, it compared with traditional materials, from the traditional 70 mpa to 200 mpa, now than traditional cutting performance of 150 times stronger.
Method 3: optimization of cutting tooth geometry size, strengthening the protection of cutting tooth, because of its high cutting tooth stress place focused on tooth around the place, so pick shape cutter tooth is the main form of damage around the tooth, rather than the root. So the geometry size and shape of it is very important. Its diameter is too small, want to have enough strength, tooth profile should be broken rock, reduce wear and tear, cut tooth tooth size too small will be to increase the cut tooth conical part of the wear and tear.
Method 4: reasonable decorate cutter teeth and optimize the hole low breakage and pick on the cutting head of reasonable arrangement is very important, it involves cutting head broken rock effectively, improve the efficiency of broken rock, reduce the cutter tooth wear and damage, the vertical axis type of heading machine cutting head is small in size, so when the layout should strive to make each rock auger bullet teeth stress equilibrium, broken volume quite, achieve the best effect of mechanics; But also reduce the sliding and wear of cutter tooth, and at the same time by using low damage even, don't too much residual rock wall, should be on the horizontal and vertical coordinates when designing low broken figure, to check the broken effect, the optimization of cutter tooth arrangement.

How to improve the market share of domestic cemented carbide cutting tool?

To improve the market share of domestic cemented carbide cutting tool, efforts should be made to take the following measures
For basic at or near the level of similar imported products domestic knives, should be on the product appearance is improved, and some surface treatment shall be increased accordingly. Intensify propaganda and improve the level of after-sales service.
Domestic tool should vigorously develop the user's rough machining market. For rough machining workpieces machining allowance, tool consumption and accuracy requirement is relatively low, the domestic cutter is easy to do, and users can use the price advantage to reduce the cost of processing.
In place of the user processing knife, tool change convenient and not affected and sequence production, domestic tool which can be promoted.
In domestic carbide inserts can not meet the requirement of the users, can consider to introduce the foreign blade, adopts the corresponding domestic blade to form a complete set, in order to improve the domestic tool performance, make the cutting tool has the advantages of low price inexpensive.
Increase the carbide cutting tools, the varieties and quantity for the user to set up after-sales service network, to help users analysis and evaluation process, to provide users with special design tools, special tools, etc.
Quality is the key to occupy the market. In publicity, promotion, as far as possible the use of domestic existing tools at the same time, actively tracking the development trend of the foreign technology innovation, absorbing foreign advanced experience, as far as possible little detours, leapfrog development, efforts to study and improve the tool design, manufacture and use of the technology, carry out technological innovation, improve product quality and performance, shorten the gap with foreign products, strive to make domestic cemented indexable carbide inserts a breakthrough in the variety, quantity and performance, increase its market share.

Carbide Indexable Inserts market share analysis.


With mechanical processing technology continues to advance, Indexable Carbide Inserts in the use of automobiles, motorcycles, heavy machinery and other industries more and more widely. From the point of current usage, domestic cemented carbide cutting tools market share is lower than the imported cutting tools, investigate its reason, mainly include the following:
1. The product quality consciousness is not strong domestic producers lack the quality consciousness of some of the knives. China Carbide Inserts material quality is poor, less varieties, the specification is not complete, the increase in the quality of the product is difficult to tools. Look from the appearance quality of the product, the import tool appearance, color and texture is superior to domestic tool. On product performance, compared with domestic knives, imported cutter machining high dimensional accuracy, good stability, high durability, high removal rate, tool and its accessories have good interchangeability, after the general assembly can meet precision requirement.
2. The pre-sale post-sale service is not perfect
Abroad a lot of cutting tool company has included for the user to choose knife, adjust knife, timely replacement of supply,, as considerate service, and many domestic tool vendors do very not enough in this aspect, the service is simple and extensive.
3. The mode of production of small workshops still accounts for a large proportion because of the economic and other reasons, some domestic tool factory still accounts for a large percentage of small workshops production mode, the processing personnel technical level is low, simple equipment, difficult to guarantee the quality of the product. Caused by tool cutting tool parts processing and assembly quality products of some quality common fault is still difficult to eliminate.
