With the development of China's economy and the improvement of living standards, automobiles as a consumer goods have become increasingly popular in people's lives. In order to seize the mainland market, the development and popularization of affordable models is the only way for major automakers to improve their market share. In this environment, satellite manufacturers that supply parts for automakers have to reduce costs to lower prices. The cost savings in processing are the most efficient and fastest methods. There are two ways to achieve compression costs:
First, the high-priced unit that was originally purchased, the tool produced by Germany and Japan is changed to a tool of the same grade with relatively low cost and no precision.
Second, to maintain the stability of the tool accuracy, the accuracy of the long-term processing changes slightly, improve the utilization of the blank, while reducing the wear of the tool, extending the life of the tool.
In order to be able to compete with German and Japanese precision, Taiwan Puhui, as a professional tool holder and tool manufacturer, has achieved this goal after nearly two decades of hard work. There have been very successful cases in Taiwan. For example, in Taiwan's Gwangyang, the earliest used are Japanese-made shanks, regardless of the shank produced in Taiwan. However, due to the fierce competition in the Taiwan market, the cost has to be reduced. After a long period of testing and trials, Puhui’s shank has been It completely replaces Japanese products in production, resulting in a significant reduction in production costs.
The same level as the German and Japanese precision is not just a slogan. Puhui reflects the production of the handle from all aspects, mainly in the following four aspects.
Material selection of the handle
The same material as the European, American and Japanese brands is used. This type of material contains the element NI, while other Taiwanese handle materials do not contain NI. When the NI element is contained in the shank, the shank does not rust easily under the same conditions, and the crystal structure after heat treatment is finer. When the thermal stress is released, the crystal structure is less expanded, so in long-term use, the shank The deformation is small, the wear resistance is improved, and the tensile strength is also increased by 20%;
Processing aspect
In order to eliminate thermal stress more effectively, on the basis of ordinary heat treatment, the deep chilling treatment is particularly increased for the shank with high rotation speed, high precision and large clamping force. For this purpose, Puhui specially selected heat treatment manufacturers with professional cooling furnaces. Its unique cooling furnace can be cooled to 196 degrees Celsius. The shank was cooled in a cooling oven for 48 hours. The heat stress release effect of the deep-cooled handle is equivalent to 30 years of natural thermal stress release, which effectively increases the wear resistance of the handle and prevents the taper of the handle from being deformed;
Strong guarantee of AT3 taper
The precision of the machine spindle is the most basic guarantee for the processing products. The machining center with high precision and high speed is millions of dollars. Therefore, how to ensure the accuracy of the spindle is not reduced for a long time, it becomes the most basic requirement of users. The taper of the shank is in contact with the inner bore of the spindle for a long time, and runs at the same high speed. The good shank taper is the key to ensure the long-term accuracy of the inner bore of the spindle. For example, the accuracy of the taper taper of the BT SK CAT and other specifications is AT, and the Japanese National Standard (JIS) stipulates that the accuracy of the shank is AT4, and Puhui self-improvement, the earliest standard in Taiwan to reach AT3, At present, the Taiwanese industry has also proposed AT3 accuracy). In order to ensure the accuracy of AT3, Puhui's high-precision grinding machine made in Switzerland is the basis of precision guarantee. The workers with more than ten years of service in the factory are qualified to be the final grinding machine. The air gauge with an accuracy of up to 0.0001 is detected as the target of the final inspection. Each tool holder is tested at the factory. Those who do not fit together are re-grinding. Ensure that the quality of the shank does not decrease;
Accuracy guarantee when clamping tools
In order to ensure that users can get the maximum precision guarantee, all the promised measurement places of precision are at the diameter of 4 times of the measuring rod, and the accuracy commitment is clearly written in the sample, which can be accepted as the quality clause. This is especially suitable for clamping non-standard forming tools for automotive engine cabinets, box covers, etc. Since the diameter and effective depth of these tools are not only 2.5 times, but larger than this number, the accuracy of the tool tip will be worse as the tool overhangs longer. However, the relationship between the two is not a simple multiple. The longer the precision commitment point is, the better the machining accuracy can be guaranteed. At present, Puhui promises that the accuracy of the heat shrinkable shank at 4D is 3μm; the accuracy of the hydraulic shank at 4D is 3μm. , PFK collet-type tool holder accuracy can also reach 5μm (the taper of this collet is 4 degrees, from the design is different from the ER 8 degrees, the same diameter clamping force is twice the ER, the accuracy is easier to guarantee ) etc. Conclusion
In summary, Puhui chooses the material from the tool holder to heat treatment, from the precision of the taper of the shank to the setting of the precision after clamping the tool, all of which are considered by the customer first, customer-oriented, and let the customer Get the best price/performance ratio. It is precisely because of this that Taiwan's Puhui can stand out in the many different brands and different handles, long-term for China Motors (Mitsubishi, Japan). Gwangyang (Japan Honda) Sanyang, Taiwan Hanxiang (aircraft engine factory), ASRock (automobile engine), Taiwan Yamaha locomotive (Japan YAMAHA) provide tool holder and tool service. Since entering the mainland market, Puhui also hopes to work with mainland steam and locomotive manufacturers to ensure quality and reduce costs, and has established a head office and delivery warehouse in Shanghai, in Jiangsu, Zhejiang, Guangdong, Wuhan, Chongqing has established a branch office directly for the automotive industry, and users can contact the nearest office. We will wholeheartedly serve our customers and contribute to the splendid future of China's automobile manufacturing.
