Turning processing process

Turning processing is an important part of the metal cutting processing, one of the most widely used in machinery manufacturing, has a very prominent place. At present, the medium and small bearing ring USES mostly multi-tool semi-automatic, automatic lathe to turning processing forgings. Processing way has a fleet of dispersed process and concentrated process. In foreign countries, the ring cutting machining using concentration process, there are scattered process method. Concentration process method is used in the structure of complex shape parts, a clamping positioning using numerical control lathe, machine tools equipped with tool library, processing, each working procedure through precise program design is completed, the product accuracy affected by man-made factors is smaller. Dispersion process method used for processing large quantities of single variety, more with the method of automatic wire processing. Widely used tools is cemented carbide coating machine clip blade, the cutting speed of 140 - 250 m/min, production efficiency is significantly higher than the domestic. Adopted the advanced processing technology of the foreign blank allowance is small, small size dispersity, turning processing are usually performed as a single, effectively shorten the processing cycle. Development, therefore, can realize strong cutting, rigid good ring turning lathe, develop good machining quality, high efficiency of microcomputer control and automatic control lathe, and is suitable for the automatic cutting production line, large quantities of single variety production is the development direction of vehicle processing. In addition, the development of cemented carbide indexable tool machine clip, surface coated tools, metal ceramic cutting tool, such as efficient tool, and realize automatic replacement blades, bringing chip broken tool monitoring system, such as a car processing research and a direction.
