Cemented Carbide Inserts

Deep Cryogenic treatment (DCT) is a one time permanent process, carried out in such a way that the material is slowly cooled down to the cryogenic temperature, after which it is held at that temperature for a specified period of time and is heated back to room temperature at slow rate followed by low temperature tempering. In this study, the orthogonal experiment method was used to study the DCT process of YT30 cemented carbide inserts. The primary relation of the different factors of DCT was analyzed. TH300 sclerometer was used to measure the hardness of inserts. The microscopes were used to observe the wearing profiles of inserts and microstructures before and after DCT. The orthogonal experiment results show that the effect of soaking temperature on the properties of inserts is the first factor, the soaking time is second one, the cooling rate is third one, and the last one is the tempering temperature. DCT improves the multi-type martensite transformation of Co. Therefore DCT increases hardness and enhance wear resistance of the cemented carbide inserts.

Surface Magnetization

The bad quality of machining surfaces caused by the micro wear of pressing parts has been a very big trouble for the engineers over the past decades. In order to decrease the surface wear, the technology of heat treatment is used popular. Many papers about the heat treatment technology had been proposed. Especially, the deep cryogenic treatment has been used widely for the purpose of wear-resistance in the industry. Moreover, the method of using variations of surface magnetization to monitor the dynamic tribological properties between the metal pairs has been applied successfully by the author. Therefore, this paper is base on the above statements to further investigate the tribological properties of the tool steel by deep cryogenic treatment. It can be clarified for effects of different deep cryogenic treatment temperatures on wear-resistance of the tool steel DC53. Besides, the purpose of better quality and faster product speed of the pressing process can then be obtained.

Deep Cryogenic Treatment

Deep Cryogenic treatment is a new technology that was dated from the later middle of 20th century and gained widely utilization. It has been proven to be a efficient method for improving the mechanical properties and working life of the high speed steel (HSS) substantially by deep cryogenic treatment. This paper summarizes the cryogenic treatment and its mechanism on metal material. Moreover, the development process of deep cryogenic treatment on HSS and its current research at home and abroad were mainly introduced.

This study investigated the effects of Deep Cryogenic Treatment (DCT) on machinability, hardness, and microstructure in dry turning process of AISI 4140 (48-51 HRc) tempered steels with ceramic cutting tools on the surface roughness (Ra). DCT process of steels has shown significant improvement in their mechanical properties. In this context, experiments were made with Taguchi L16 method and optimum values were determined. Three different values for each control factors as: different heat treated samples, cutting speeds (160, 200, 240, 280 m/min), feed rates (0.08, 0.12, 0.16, 0.20 mm/rev) were selected. As a result, the lowest Ra value was found to be 0.159 µm for the DCTT36 sample at a cutting speed of 240 m/min, a feed rate of 0.08 mm/rev. The optimum Ra value was the lowest for the DCTT36 sample compared to the other samples as 0.206 µm. The hardness values of the micro and macro were highest for the DCTT36 sample. Microstructural point of view Scanning Electron Microscopy (SEM) point of view, the DCCT36 sample showed that best results owing to its homogeneity. It was concluded that lower Ra values can be obtained with ceramic cutting tool in dry turning experiments according to the studies in the literature review. It is thought to be preferred as an alternative to cylindrical grinding process due to lower cost.
