what should we do for small parts processing with short tool life and poor surface quality? How to achieve stability, high efficiency and high quality in aluminum alloy processing?
This article aims at the sore points and difficulties of small parts processing and high-efficiency and high-speed processing of aluminum alloy, and provides solutions for everyone. As a supplier of cutting tools, SZSUNLIT insists on deep cooperation of end users, lean quality and innovative service, and has launched more and more new products with independent intellectual property rights and won high praise from the market. Several products, both in terms of technical level and customer service, all reflect the increasing innovation ability of Chinese cutting tools.
Precision cutting technology
Precision machining is an important technical way to promote the performance improvement of high-grade CNC machine tools, aerospace equipment and offshore engineering equipment. It can achieve high surface quality, low material removal rate, low residual stress and good processing stability. Precision machining tools are mainly optimized in terms of material, structure and technology. At present, the main research focuses on the tough/hard matrix, new coating and angle design of tools. With the rapid development of manufacturing industry, the demand for small parts is increasing day by day, and it is widely used in automobile industry, electronic information, engineering machinery, medical equipment and other fields. The design and manufacture of tool base and special coating, the optimization design of tool structure and the compound processing technology of tools have become the important directions of the development of small parts tools. The market of small parts processing has a large capacity, but it also poses many challenges to tool suppliers, such as complete product series, good accuracy and stability, applied technical services and program development. After years of polishing, we have condensed the latest selection, design and technology of SZSUNLIT in matrix, structure and coating, etc. We are confident that we can solve small parts processing problems for users and help precision manufacturing.
SZSUNLIT fully investigated several small parts processing enterprises, and learned the needs and difficulties of small parts processing.
In the aspect of matrix, the machining of small parts requires every cutting tools to have good dimensional accuracy. After in-depth study of the powder distribution law, we selected the material of XTC to improve the matrix deformation. After high-precision grinding technology and special cutting edge treatment technology, the minimum arc radius of the tool tip can reach 0.03mm, and the arc connection is smooth. On the basis of ensuring the sharpness of the tool tip, the cutting edge is in good condition.
In terms of coating, this series of cutting tools are equipped with special nano coating, which has excellent wear resistance and oxidation resistance. In addition, the substrate adopts a fine pretreatment process, combined with a unique coating droplet control technology, and the finally formed coating has a smooth surface and low friction coefficient, thus ensuring the surface quality of the workpiece.
In terms of structure, SZSUNLIT provides one-stop milling solutions for all series of small parts, optimized groove design, solving the processing difficulties of small parts, large rake angle and sharp edge, reducing cutting force and obtaining excellent surface quality; Grinding small circular arc to meet the needs of high precision machining; Special chip breaker and small slot width design can meet the chip breaker requirements under different working conditions.
In addition to the development and innovation of the product itself, SZSUNLIT has also made great efforts in the overall solution. Take the common camera ring as an example, there are difficulties in the production that require high surface quality and production efficiency. Thirdly, through research and planning, technical platform and product development, a brand-new solution was given, and the machining path and chip-removing groove were optimized, thus achieving better surface quality. Furthermore, by optimizing the cutter structure and machining parameters, higher machining efficiency was achieved. In the future, SZSUNLIT will provide better tool solutions in more small parts processing fields.
High-efficiency and high-speed machining tool for aluminum alloy
In recent years, with the development of machining technology for large-scale aluminum alloy structural parts, higher requirements are put forward for aluminum alloy cutters, especially for the improvement of machining efficiency under high-speed working conditions. The series of aluminum alloy high-speed and high-efficiency end mills developed by SZSUNLIT, which includes three kinds of special cutters: rough machining, side wall finishing and web finishing, are based on the overall efficiency improvement strategy of changing low-speed small-cut deep milling into high-speed large-cut deep processing. By integrating internal cooling form, anti-vibration design of cutter type, coating technology development, etc., the cutters have the characteristics of long life, high efficiency, good stability and good workpiece surface quality, which effectively solves the problem of poor surface quality and low size control ability when traditional cutters process aluminum alloy thin-walled structures with weak rigidity.
In order to ensure stable machining performance, besides the tool itself, the tool handle also plays a vital role. We recommend using hot-loaded tool handles. Aiming at the sore points of low precision, easy tool dropping, short service life and poor rigidity, high-quality hot-working die steel is selected, and the surface of the tool handles are coated, so that the clamping force is large and the service life is long. Slender structure design, excellent avoidance; High precision and good dynamic balance, suitable for high-speed machining, which can reduce tool wear and production cost.
SZSUNLIT live up to expectations, showing the in-depth insight of domestic cutting tools on user needs, processing pain points, and efforts and strength in R&D and innovation. With the breakthrough in core technology and service capability, I believe that domestic cutting tools will definitely create more value for end users and have a broader future!
