Innovative tool design reduces manufacturing costs

       With the vigorous development of the automobile manufacturing industry, how to improve the manufacturing efficiency and effectively reduce the manufacturing cost under the premise of ensuring the quality of automobiles has become the focus of increasing attention. Studies have shown that replacing traditional tools with more advanced cutting tools is seen as an effective way to reduce costs and increase efficiency in automobile manufacturing.

       In the process of auto parts processing, the cost of hole processing and milling occupies most of the processing cost of the whole part. The cost of hole processing remains high. First, it is difficult to process some holes. Second, the traditional hole processing cost control method needs to be improved. Traditional hole machining cost control is achieved by regrinding the tool. However, there are three major problems in grinding: one is that it is difficult to locate during grinding, and the shape of the tool tip is easily deviated; the other is that repeated grinding will reduce the diameter of the drill bit; the third is that each regrind will shorten the overall length of the drill bit.

       In order to solve the problem of hole machining and achieve cost reduction and efficiency increase, Zheng Zuan has developed a series of special tools for difficult-to-machine holes. Taking the machining of valve seat and guide hole as an example, the machining accuracy of valve seat and guide hole directly affects the power and exhaust emission indicators of the engine. A series of special hole machining tools such as machining tools can easily achieve the precision of the valve seat ring, the guide hole pressure ring and the pressure ring, which can effectively avoid the problems of repeated tool adjustment, fast wear and deformation, and low processing efficiency that trouble the user, and at the same time can guarantee the valve The matching clearance with the seat ring ensures the heat dissipation and sealing performance of the valve. Among them, the rough machining tool of the tappet hole realizes the perfect thermal shrinkage of the carbide drill bit and the PCD reamer; the 3μm runout of the cutting edge ensures that the tool has a longer service life and higher processing accuracy; Reaming is precisely guided; the original chip changing technology ensures that the reaming accuracy is consistent with the new tool, and the tool cost is reduced without reducing the cutting quality. The axial rake angle design of the tappet hole finishing tool reduces the axial force and makes cutting easier; the unequal pitch structure can effectively avoid marks and make the cutting more stable; the inner cooling design of the tool ensures smoother chip removal.

       The diamond guide bar tool for crankshaft and camshaft hole machining adopts a unique guide bar structure to ensure the accuracy and stability of large aspect ratio boring, and the cutting edge is 3μm The runout ensures long tool life and high dimensional accuracy, and the flange connection structure can be adjusted, which is mainly used in high-precision machining of crankshaft and camshaft holes.

       Smooth, flat surfaces on the cylinder head and block are important for proper engine operation. Automotive engine manufacturers have been striving for controllable, predictable levels of surface finish, and higher productivity, while maximizing tool life and minimizing tooling costs in each part machined. The series of aluminum base face milling cutters developed by Zheng Zuan for the milling of the cylinder head joint surface based on the user's needs, adopt innovative tool design thinking, while meeting the user's processing quality requirements, greatly improve processing efficiency and reduce tool costs. Among them, the MFAC30 and MFAC31 series of aluminum base face milling cutters are suitable for processing non-ferrous metals such as aluminum and aluminum alloys, copper and copper alloys, as well as wood and plastics, and are suitable for rough and fine machining of high-efficiency face milling. The internal cooling design optimizes chip treatment, making chip removal smoother and higher processing speed; the machine-clamped blade is clamped, the blade can be ground and replaced, and the cutter head can be reused, which greatly reduces the user's tool purchase cost; the circular runout can reach 0.001mm, which guarantees the precision of the workpiece; the 2mm adjustment range increases the number of times the blade can be sharpened; the wrench can be used to directly adjust the position, which is very convenient and fast.

       Another high-speed CBN indexable finishing disc milling cutter for cylinder joint face milling innovatively uses solid CBN inserts, compared to traditional alloy inserts, whether the insert is There are great advantages in service life and surface finish quality. The innovative design thinking makes the cutter head process a certain angle, and the blade can cut without the need for a clearance angle, which makes the blade processing easier, the quality of the blade is more guaranteed, and the service life of the blade is doubled. The blade adopts an indexable design structure to ensure that all 8 corners of the square blade of the blade can be used, which increases the service life of the blade geometrically. Due to the design of CBN inserts, the cutter head can maintain a high feed and speed while ensuring the quality of the machined surface. While multiplying the surface roughness value and multiplying the blade life, the processing efficiency is higher than that of alloy inserts. more than doubled. The innovative design concept enables the cutter head blade to be adjusted in both axial and radial directions, so as to ensure that the end tooth runout and the cutter head outer diameter runout can be adjusted to less than 0.005mm when the blade is installed on the cutter head, which can be effectively processed during machining. Ensure that each blade is subject to the same wear and prolong the service life of the blade.

       For 20 years, Zheng Zuan has always been focusing on the cutting tool industry, meeting changes with innovation, carefully casting products, and is committed to providing users with impeccable cutting tools, working hand in hand with users Stand on the front line of production, solve cutting problems, reduce costs and increase efficiency, and become a trusted tool expert and tool steward around users.
