According to the demand of the market after the clip-on threading tool is currently widely used machine clip-on threading tool, but machine clip-on threading tool divided into two parts, tool holder and the blade knife pad, mounted on the cutter bar clamp with bolt, blade mounted on the mat, then the blade is divided into carbide coating blade (used for processing non-ferrous metal blade, such as: Aluminum, aluminum alloy, copper, copper alloy and other materials), carbide coated blade (used for processing steel, cast iron, stainless steel, alloy materials, non-iron metals, hardened steel, etc.).

At present, there are about 90,000 metal non-metallic mines in China, of which 95% are small mines. Most of these small mines have no formal design, the mining process is backward, the equipment level is low, and the safety protection capability is seriously inadequate. Some small mines have no licenses or licenses or licenses are incomplete. They try every means to avoid cracking down on governance, and continue to illegally produce and operate in violation of laws, and interfere with normal operations. The order of mineral resources development and the order of market economy; some small mines have a complete “five certificates†in their nominal names. In fact, problems such as exploration and production mining, cross-border mining, and illegal discharge have caused serious problems and hidden problems; some owners’ awareness of safety production laws is indifferent. There is no guarantee of safety investment, safety training goes through the field, safety precautions are not implemented, safety management is chaotic, and the safety and health rights of the majority of miners cannot be guaranteed; the safety and safety skills of the employees need to be improved, and there is a general lack of management that can meet the requirements of safety production. Personnel, technicians, and job operators have serious violations and violations, resulting in frequent occurrences of accidents such as collapses, roof linings, poisoning suffocation, falling tank sports cars, flooded wells, explosions, and tailings dam breaks, which cause damage to the lives and property of the people. Serious loss.
In order to solve the problem of “multi, small, scattered, and poor†metal non-metallic mines as quickly as possible, and better grasp the initiative for safe production in non-coal mines, Yang Dongliang deployed the key to rectify the closure of non-coal mines and made it clear that any mining permit was not obtained in accordance with the law. Such as licences, business licenses, safety production licenses, etc., engaging in the mining of mineral resources without authorization; resuming production without authorization after closure; existing unlawful acts such as investigative mining, cross-border mining, etc., and refusing to rectify; violation of construction project safety facilities The "three simultaneous" provisions of pollution control facilities, refusal to implement safety and environmental protection supervision directives, and overdue completion of related procedures; mining licenses and safety production licenses expired and invalidated, etc., must be included in the list of rectification and closure.
Secondly, for those who have major hidden dangers and there is no hope of rectification; technical equipment is backward, safe production and environmental protection are not guaranteed; small open pit mines do not have formal design and do not implement prescribed safety technical measures; If an accident or a secondary incident is more serious, it must be rectified and closed.
In addition, for those that do not meet the requirements of mineral resources planning and setting of mining rights and do not meet the minimum mining scale of relevant minerals required by the national or local governments, the backward technologies, equipment, and equipment that have been explicitly eliminated by the national or local governments shall be within the prescribed time limit. If the rectification has not been rectified, and the independent mining company has no fixed ore sources, the mining enterprises must seriously rectify or shut down according to law.
Yang Dongliang said that to carry out metal non-metal mines to close and fight tough battles is a multi-final cure. It is not only a practical need to solve outstanding problems in non-coal mine safety production, but also helps to protect precious mineral resources, protect the ecological environment in the mining area, and accelerate the adjustment and optimization of the mining economic structure.
Yang Dongliang, director of the State Administration of Work Safety, revealed on September 19 that at a national coal mine non-coal mine rectification and closure and “doing non-rule violations†promotion meeting, the company will organize and organize a nationwide non-metallic mine rectification and closure campaign. The State Council’s safety committee determined that from now until the end of 2015, it will eliminate and close down 20111 non-coal mines that are illegal, illegal, and inconsistent with national and local industrial policies, and have low safety guarantee capabilities, basically solving the problem of multiple accidents in non-coal mines.
