According to industry experts, using a cutting tool as an example, the best condition can be obtained when the tool itself is selected for proper surface treatment. For example, medium and heavy load molds, CVD high-temperature titanium plating and precision vacuum heat treatment are needed to make the deformation Within the acceptable range, it is commonly used in cold forging dies, hydraulic drawing dies, tungsten carbide draw lines, and suction pipes.
In addition, in the application of low-load or high-precision tools, molds and machine parts, the industry pointed out that the use of low temperature (150 degrees Celsius to 500 degrees Celsius) PVD titanium plating is more appropriate, commonly used coating is TiN, CrN , TiCN, AlTiN. Among them, TiN film is the most common and the cheapest; and CrN film (commonly known as white diamond, platinum, white titanium) has a temperature resistance of 700 degrees Celsius, and has a low coefficient of friction and good corrosion resistance, especially for stainless steel and copper. Cutting of aluminum, aluminum and other alloys has a significant increase over the service life of TiN films. The TiCN film has a tendency to gradually replace the TiN film. It is a multilayer film with a hardness of Hv4000, which can increase the service life of the TiN film by 30% to 50%; AlTiN should be selected for high-speed dry cutting. Membrane, this is a new generation of dual alloy coating with a hardness of up to Hv5000 and temperatures up to 850 degrees Celsius.
As for how to achieve the most appropriate results, the industry said that whether the high temperature or low temperature coating surface treatment must choose the appropriate substrate and a stable heat treatment, supplemented by the surface fine grinding fine polishing pre-treatment, can only be ideal.
The industry pointed out that with regard to hydraulic buffers used in machinery, the design has been oriented towards the full range of customized designs for customers, such as outdoor and military machinery, overhead cranes, high-temperature and wet locations. Therefore, the design needs to withstand a long period of testing, in order to become a strong, all-weather product, this type of product in the production process, its surface is highly hardened heat treatment HRC60 degrees and chrome-plated rust-proof anti-corrosion treatment .
Modern machine tools put high demands on equipment and accessories machinery
According to overseas media reports, the quality of consumables such as related peripheral equipment and machinery parts has also been inspected to meet the development trend of modern machine tools such as high-speed, high-precision, and high-quality R&D. This has enabled the industry to examine molds, cutting tools, and machinery. The demand for surface treatment such as fittings has become stricter. Among them, prolonging the useful life, lowering production costs, and creating higher profits are arguably the same standards for the industry.
