Use square shoulder milling cutter cavity coarse milling, semi-finishing would remove the bulk of the stepped cutting margin. This will allow the cutting force changes, so that the bending tool. The result is to leave uneven finishing allowance, thus affecting the geometric precision of the mold. If you use the tip strength weaker square shoulder milling cutter (with triangular blades), it will produce unpredictable cutting effect. In heat production practice, the work of some of the special shape of the use of large or when the protective salt bath furnace heating method is not easy. If you must use box-type furnace or reverberatory furnace heating, these large or special shape of the workpiece, according to the following methods to prevent oxidation and decarbonization work. The continued strength of the recent rise in construction steel kinetic energy has been significantly weakened, leading regional Beijing, Xi'an prices flat, rising exploration area is also just stay in the individual regions. Currently in Beijing, Tianjin steel prices remained at about 2750-2780 yuan, hot-rolled coil, cold rolled coil and plate market prices fell slightly accelerated momentum, Handan hot-rolled coil prices continue to refresh the current National Low 2920 Yuan, lock the current steel plate market price is still stuck in 2830 yuan, but the latest orders is less than ideal spot market mainstream, the lowest price is the probe to the 2830-2850 yuan, cold rolled coil market price adjustment region is today gradually increased. When the mold to complete production tasks should take different approaches depending on the injection carefully remove residual injection, available copper rod, copper wire and professional mold cleaners remove residual injection mold and other deposits SK5 wholesalers, and then air-dried. Disable hard objects Dongguan mold steel wire, steel bars and other cleanup SK5, so as not to scratch the surface. Rust SK5 steel prices Dongguan mold injection if corrosion caused, to use the grinder polishing and spray on a professional anti-rust oil, then the mold in a dry, cool, no dust at the store. Laser in particular for a tire mold cleaning SK5 sheet, mold absorb specific wavelengths of energy is very small, will not cause damage to the mold surface dirt (sulfides, inorganic oxides, silicone oils, carbon black, etc.) to absorb a lot of energy, is instant expansion, vaporized, away from the mold surface, so as to achieve the cleaning effect. Laser cleaning methods are: 1) Laser dry cleaning method, which uses pulsed laser direct radiation decontamination; 2) Laser + liquid membrane method, which first deposited on the surface layer of the substrate film, and then use laser radiation decontamination; 3 ) Laser + inert gas, i.e., while the laser radiation, with an inert gas purging the substrate surface. When the dirt from the surface of the release, it will immediately be blown gas from the surface, in order to avoid contamination of the surface again. Learn from the advanced mode of cooperation overall development layout, attract industry leaders building demonstration of industrial projects, the introduction of domestic research institutes, construction research collaboration agencies to support the development of relevant policies, and strive to 5 years or so to build the annual turnover in the "City of Mineral" demonstration base 50 billion yuan scale.
