7. The solution to provide the overall solution is a long-term advantage of the internationally renowned tool companies. This is an example of the engine camshaft hole compound boring tool exhibited by Cobalt Company. According to reports, this type of boring tool uses cemented carbide as the base of the shank, which has good rigidity, is not easy to bend, and has excellent shock absorption. The longer shank part uses a stable and reliable spiral blade for better guiding and supporting. The cutting edge portion of the file has a multi-directional multi-size fine adjustment mechanism, which ensures the processing of the camshaft hole stably and reliably. The line knives of the company are also typical of the machining of the cylinder block of the automobile engine. The wire boring tool simultaneously performs boring processing on a plurality of holes on one axis, but the processing size of each boring head can be separately adjusted, and has good processing efficiency and processing quality.
Crankshafts are also a typical component of machining solutions that are particularly needed in automotive manufacturing. Langfang Baistu Company demonstrated the model of its crankshaft milling cutter at this exhibition, and Zhuzhou Diamond showed the scheme of crankshaft external milling. These reflect the continuous improvement of domestic tool manufacturers in the field of automotive manufacturing. Basstu's crankshaft internal milling cutters use flat-blade inserts and use knife inserts and wedges to protect the cutter body. Therefore, the machining of such a cutter structure is difficult. The supplied crankshaft internal milling cutter has a maximum machinable diameter of 1 m. According to the company, the company can also provide high-quality crankshaft milling cutters and crankshaft broaches and truck pull tools.
Wuxi Fanginch Company also showed its special non-standard tool. It is a turbo turret shell air passage reaming and kit combination rough boring tool developed for users. The inner hole and some end steps can be processed at one time during processing. forming. The material of the workpiece to be processed is the heat-resistant stainless steel of German Standard 1.4848, which has a severe test on the life of the blade blade, and the products of Fanginch Company also have good performance. Fanginch also exhibited another solution for the tool, which is used for the thick shaft of the elevator motor housing and has high processing efficiency.
Seco also exhibited a number of special tools, such as the root groove semi-finishing cutters developed for the steam turbine industry, special-shaped broaches and so on. The blade root groove of steam turbine is an important difficulty in the manufacture of steam turbines. However, Seco has rich experience in machining in this respect. It knows the mystery of high-precision machining of heat-resistant and difficult-to-machine materials. Its root-slot semi-finishing cutter is mainly used for processing. The root portion of the blade. The special shape broach exhibited on it can be applied to the ordinary 4-axis or 5-axis machine tool for broaching. The advantages are: the machine is installed once; the surface quality is better finished; no special broaching machine is required; Milling profile machining; blade structure, requiring only blade replacement, no regrind; lower cost and shorter lead times.
Gaomet exhibits unfolding tools, or moving tools, U-axis tools. According to Gaomet, the built-in servo motor controlled by the machine program drives most of the front-end tools to change the diameter, which can realize the processing capability of the special machine. In the machining center, a high-tech U-axis tool can be used to realize step-by-step boring, raking, profiling or reverse chamfering. It is a boring μ-level compensation and non-revolving workpiece contour machining. The perfect solution.
8. Tool holder Germany BILZ Company exhibited its upgraded cooling king tool holder. The outer casing and the tool holder have become one. The coolant is directly transported from the inside of the tool holder to the hole in the end face of the tool holder and sprayed toward the tool.
Hanmer exhibited the Cool Flash knives (Fig. 16) with a thin slit instead of a small hole at the end, and the end of the slit was directly attached to the shank. This structure enables the cutting fluid to form effective cooling along the shank even when rotating at a high speed.

Among the domestic exhibitors, Hazen exhibited its professional tool holders developed for the IT industry (Figure 17). The main features of the tool holder used in the IT industry are miniaturization, high speed, and high precision. In the past, a large number of tool holders for the IT industry were mainly from Japanese manufacturers. With the vigorous development of the domestic IT industry, this tool holder developed by Harmony will play a positive role in meeting the application of more IT industry.

Shanghai Songde Company exhibited its powerful chuck (Fig. 18). According to reports, its clamping accuracy is high (beating at the 3 times diameter of the tool is ≤0.005mm), the structure is symmetrical design, the rotary dynamic balance is G6.3, and the rotational speed can reach 12000r/min. This powerful collet features a full protection design with built-in extreme pressure grease to increase the life of the tool holder. Songde Company emphasizes its unique internal cooling design, covering a wide range of shank, not only the body-sized shank can meet the needs of internal cooling sealing, but also fits the sealed inner cold straight collet, which can also meet the internal cooling of all adapting arbor need.

9. Digital products Kennametal exhibited its intelligent tool selection NOVO at this exhibition, which includes four modules: tool consultant, tool selection, tool configuration and project management. The tool advisory module can provide cutting tool recommendations according to the processing characteristics and requirements, taking into account the processing sequence requirements; the tool selection provides another way to select the cutting tool from the tree structure or through the hierarchical search, greatly improving the tool selection. Efficiency; the tool configuration includes options for “fit and match†and “machining and matching†to provide real-time assembly of 3D models of parts and is compatible with the most commonly used CAD-CAM systems. Another product worthy of attention at the show is Gomet's ToolScope process monitoring system, a tool that provides customers with a safe process, ideal for high-speed machining and unattended operation. Gomat believes that in the era of Industry 4.0, it is necessary to be able to make increasingly complex manufacturing processes controllable, to make previously unrecordable production details traceable, and to achieve sustainable profitability in environmental and demand changes. . Therefore, the ToolScope process monitoring system is mainly used to monitor and optimize various machining processes. (End of the article) (Handwriting: Yang Xiao)
