High speed transformation of processing equipment
High speed machining can improve the productivity of enterprises and shorten the delivery time. In order to achieve high-speed machining, machine tools, fixtures and tools must meet the relevant requirements, mainly including the following aspects: first, the machine tool should be equipped with a spindle that can realize high-speed operation, so as to meet the needs of high-speed machining in terms of speed; Secondly, HSK hydraulic chuck should be equipped with enough rigidity and positioning accuracy to ensure the smooth progress of high-speed machining; Third, a large number of coated cemented carbide tools are required, such as those made of cermet, ceramics, CBN, PCD and other materials, so as to ensure that the tools will not be worn prematurely under the condition of high-speed machining.
Machining hard parts with hard tools
Using the coated carbide tools mentioned above to process hard workpieces can realize the purpose of simplifying process methods, process links, saving costs, and flexible processing. For example, when machining the camshaft journal in the engine, the traditional method is to use the process of turning first and then grinding. Since CBN cemented carbide tools are used for machining, grinding can be omitted, and the requirements for surface roughness can also be met. This not only simplifies the processing process, combines the two processes into one, but also improves the processing efficiency and greatly saves processing time.
Dry cutting becomes a popular choice
Dry cutting is a cutting method that is not suitable for metal working fluid, and has high requirements for the heat resistance of tools. The advantage of this cutting method is that it is more economical and environmental friendly. For example, in the rough machining of the cylinder bore of the automobile engine block, if the ceramic blade is used, there is no need to add emulsion, which can save a lot of expenses. At present, in foreign countries, dry cutting has been paid more and more attention, and has become a popular choice in industrial production. In addition, the quasi dry machining, which is between the traditional machining method and the dry cutting method, the machining method of adding cutting fluid by spray, has also made great progress and become more and more perfect.
Application of flexible automatic production
Flexible machining is a higher realm pursued in machining. It can deal with various batches of parts with various requirements without additional costs. In the traditional automatic production line, CNC or machining center is used for local stations, and the production line that realizes flexible processing is called flexible automatic line. The flexible manufacturing system composed of special machining center is mainly used in the production of engine cylinder head and cylinder block to adapt to the uncertainty of purchase order. At present, the use of flexible and automated hybrid production lines has become a new trend. In technology, large amount of cutting can be completed on the traditional automatic line, while the processing of the front and rear end faces and sides of the cylinder body can be completed by using flexible production units.
