Reasons for the low quality of Chinese alloy saw blades:
1. After a survey of most of China's alloy saw blade manufacturers, we found that Chinese saw blade manufacturers are trying to find ways to improve their product quality. The most notable is that the problem of low quality of saw blades in more than 80% of China's manufacturers mainly occurs on welding and steel plates. I have received a test article sent by a domestic company. In the completely new situation, the steel plate is actually There is a crack of up to 30MM. If the saw blade is at a speed of 3000~8000, it may have unexpected results, let alone what the sawing effect is: low welding fastness and fragile alloy. The alloy is subject to high oxidation and large solder joints. At present, more than 80% of the welding methods used by Chinese saw blade manufacturers are current butt welding.
2. Another reason is that the precision of the grinding machine made by the Chinese is not enough.
Why are Chinese companies not willing to purchase advanced automatic welding equipment and grinding equipment imported from abroad?
In our investigation, we found that Chinese saw blades are mainly based on the advantages of low production cost and large quantity. They rely on exports as the main force to operate the company. They are used in the lowest-end industries in foreign countries, and most of their profits are earned by foreign companies. In order to change the quality of products, some enterprises in China have to sacrifice heavy money to purchase imported automatic high-frequency welding equipment. Among them, 5% of the companies have purchased fully automatic high-frequency welding equipment imported from Germany, and 5% of the companies have purchased fully automatic welding equipment from Japan. These companies that purchased fully automated equipment purchased equipment and found that investing millions of dollars did not export the products abroad. The reason is that the quality of fully automatic imported high-frequency welding equipment has been upgraded, but the output has not improved, and the original advantages of Chinese enterprises have been lost. In addition to the cost of machine depreciation, export and transportation, the cost of the product is very expensive, and the price of the alloy saw blade produced locally is not bad. Then, with the manual high-frequency welding equipment produced in China, the same cost can be produced to produce a saw blade that exceeds its 35 times production. Obviously, Chinese products can quickly occupy the market in the world. The Chinese do not have to spend a lot of money to buy foreign saw blades. (For example, investing in a fully automatic high-frequency welding equipment imported from abroad requires 700,000 RMB, and its output is 1200 sawtooth/hour. The investment of 700,000 RMB to buy the high-frequency welding equipment produced in China can also achieve a minimum of 42,000 sawtooth/ hour.)
1 imported automatic high-frequency welding equipment = 700,000 RMB = 1,200 sawtooth / hour 55 domestically produced high-frequency welding equipment = 700,000 RMB = 39,600 sawtooth / hour (worker skilled person can also increase production by 10%)
Chinese companies should allocate equipment imported from abroad. We recommend using imported grinding machines, but we also need to constantly master and summarize the updated experience to grind good saw blades. We can't just look at the problem with old qualifications and old eyes, because some companies in China have already purchased foreign grinding machines, but they have not made good saw blades. This is worth our attention.
The status quo and development of domestic saw blade enterprises
China is one of the countries with the largest production of saw blades in the world. However, the price of saw blades has been falling, so many manufacturers have stopped production due to low profits, and closed down. Foreign saw blades are quietly entering the Chinese market at nearly 100 times the price and selling well. Not bad. The reason is worthy of our thoughts!
