Xinyi Electromechanical Co., Ltd. is a privately-owned manufacturer of electric shavers, which has developed rapidly in just a few years. In the production of razors, a circular saw blade cutter with a thickness of less than 1 mm must be used. Due to the special material of the saw blade and its heat treatment, it is difficult to process with other processing methods. The saw blade has 90-100 tooth shapes, and the beating error of the tooth point is required to be within 5 wires. This precision requirement does not seem to be high, but the actual weight is 0.5 μm for each tooth, so the manufacturing difficulty of the machine tool is indeed not small.
At the beginning of this year, after receiving the order from Xinyi Company, Hangji Company carried out necessary rectification of the machine tool for the material and characteristics of the saw blade. At the same time, we carefully study the user's process, formulate a perfect plan, and repeatedly test on the machine tool. The 400-piece saw blade is superimposed with a CBN grinding wheel for single-tooth primary forming grinding, and the CNC indexing mechanism is used to realize the full-circumference indexing grinding function of the workpiece. In order to make the machine meet the user's accuracy requirements, the technicians have improved the grinding process path several times through several months of research, and finally the blade tooth profile accuracy is controlled within the required range. In the trial grinding of the user's pre-acceptance work performed not long ago, the tooth profile accuracy of the saw blade is much higher than the user's requirements, and the user is very satisfied with the machine tool.
Strong forming grinding to the light industry
The MKL7120×6 CNC powerful forming mill exhibited by Hangzhou Machine Tool Group Co., Ltd. at the China International Machine Tool Show has recently passed the user acceptance and will soon be registered in Zhejiang Haining Xinyi Electromechanical Co., Ltd.
