When the carbide milling cutter is performing reverse milling, the carbide milling cutter blade starts cutting from zero chip thickness, which will generate high cutting forces, pushing the carbide milling cutter and the workpiece away from each other. After the carbide milling cutter blade is forced into the cut, it usually contacts the machined hardened surface caused by the cutting blade, and produces a rubbing and polishing effect under the action of friction and high temperature. The cutting force also makes it easier to lift the workpiece from the workbench. When the carbide milling cutter is performing down milling, the carbide milling cutter blade starts cutting from the maximum chip thickness. This can avoid the polishing effect by reducing heat and weakening the machined hardening tendency. It is very beneficial to apply a maximum chip thickness, and the cutting force makes it easier to push the workpiece into the carbide milling cutter so that the carbide milling cutter blade can perform the cutting action.
With the rapid development of science and technology and the continuous improvement of armor protection technology, the requirements for high-density tungsten alloys for bullets are getting higher and higher, especially the requirements for high strength and good toughness under the premise of ensuring high density. In sports goods, tungsten alloys can be used to make the crankshaft of racing cars, which can greatly improve the performance of racing cars. The edges of golf balls and tennis rackets are inlaid with tungsten alloy weights, which can make the rackets have stronger attack capabilities; in heavy arrow competitions, when the arrowhead is made of tungsten alloy, the hit rate of heavy arrows can be greatly improved.
Tungsten alloy electroplating technology ushered in a year of rapid development. Tungsten alloy electroplating chromium replacement technology, tungsten alloy electroplating chromium replacement technology Chromium plating is a traditional processing technology, widely used in the field of functional coating and decorative coating. The annual output value of chromium plating industry in the United States reaches 8 billion US dollars, and China exceeds 10 billion yuan. Hexavalent chromium produced in the chromium plating process is a dangerous carcinogen. Environmental protection departments in various countries around the world have strictly controlled the discharge of chromium mist and chromium-containing wastewater. Completely canceling chromium plating has become a major task for environmental protection departments in various countries around the world. Therefore, finding a chromium replacement process has become a need for all manufacturing industries. The hardness of tungsten alloy knives is Vickers 10K, second only to diamonds. Because of this, tungsten alloy knives are not easy to wear, and they are brittle and hard and not afraid of annealing. Its price is much more expensive than that of ordinary milling cutters, and the price is proportional to its knife length and diameter.
