Chongqing successfully developed dry-cut hobbing machine equipment

Recently, the State Key Laboratory of Mechanical Transmission of Chongqing University has fully utilized its basic theory and common technology research advantages in the field of gear specialization, and combined with Chongqing Machine Tool (Group) Co., Ltd. and Chongqing Tool Factory Co., Ltd. High-speed dry hobbing process system cutting heat transfer model and temperature field control technology, gear high-speed dry hobbing process parameter optimization and numerical control automation programming software, powder metallurgy high-speed steel coating high-speed dry-cut hob, seven-axis four-link high-speed Key technical problems such as dry-cut CNC gear hobbing machine, successfully developed YDZ3126CNC high-speed dry-cut hobbing machine equipment, and achieved efficient, energy-saving and environmentally friendly machining of gear hobbing. This achievement has filled the domestic gap and reached the international advanced technology level. At the same time, the sales price of this product is only 60% of the foreign machine tools of the same technical level, and it has strong market competitiveness. It has replaced the import sales of more than 100 units and has won good economic benefits.

Gears are the basic components of the equipment manufacturing industry, with an annual output value of 200 billion yuan. At present, China has widely used the wet hobbing process in the field of gear processing, which requires a large amount of cutting oil, and the cutting of oil mist and drip waste oil causes serious environmental pollution of the workshop and operator health hazards. With dry cutting equipment, it can double the processing efficiency, reduce the processing cost by about 20%, and achieve zero pollution. This product adapts to the urgent needs of China's manufacturing green manufacturing innovation transformation, and the prospects are very broad.
