ZK5540 CNC Gantry Mobile Drilling Machine is a CNC gantry mobile multi-head drilling machine for nuclear power steam generator orifice plate processing according to the requirements of China Dongfang Electric Corporation. The successful development and manufacturing of this special "working machine" will make an important contribution to the development of China's nuclear power industry. ZK5540 CNC gantry mobile multi-head drilling machine is equipped with high-power speed boring and milling head on the beam. It has 5 feed axes (can be connected with any three axes), processing width is 4.5 meters, gantry moving processing can reach 9 meters, machining hole diameter It is 10~40mm, can be loaded with multiple stations at the same time or can be processed by 8-axis station at the same time. The precision between holes is 0.05mm. It is an ideal "tool" for the processing of porous tube plate parts. It is a CNC gantry milling drill or The family of drilling machines has added a new “new†to fill the domestic gap.
It is reported that ZK5540 CNC gantry mobile multi-axis drilling machine has replaced imports, and the price is less than 50% of imports. This equipment is the first in China, with advanced technology and high efficiency. It adopts the latest technology of internationally recognized and well-known foreign manufacturers, and has the international advanced level of similar products. It is an advanced equipment with high efficiency, high precision, high reliability, high speed, high dynamic response and high rigidity. The machine tool developed a high-speed eight-axis milling and drilling spindle system based on the gantry mobile boring and milling machine. First of all, it has obvious efficiency advantages. Reasonable adjustment of the spacing between the drill shafts and the maximum simultaneous use of the eight-axis drilling will greatly improve the production efficiency, thus bringing considerable economic benefits to the enterprise. Secondly, the machine tool is highly automated, multi-axis linkage, good control precision and high machining accuracy. Its high-speed electric spindle processing, high drilling efficiency, good hole wall finish; in-situ detection technology can monitor drilling quality and bit cutting in real time to ensure safe drilling (so that the drill bit will not break or other abnormal phenomena during drilling) ), to ensure that the scrap rate is zero. At the same time, no need for shutdown detection, saving auxiliary processing time and improving processing efficiency. In addition, the spacing between the eight spindles of the machine tool can be adjusted to meet the processing of tube sheets with different hole spacings; the machine can also be equipped with accessory milling heads or boring tools for boring and milling, one machine for multiple use, and one part of the parts is realized. Breakthrough in processing and key core process technologies.
Background Links The developed industrial countries in the world began research on processes and equipment for nuclear power tube processing as early as the 1970s. The development of numerical control technology and monitoring technology has enabled the rapid development of tube sheet processing equipment in terms of high efficiency and high precision. It is the fastest growing country in Germany, Italy, the United States, etc., and the technology of the products has reached a fairly high level. This kind of machine tool has not been designed and produced in China. If it is purchased abroad, the same performance eight-axis gantry drilling machine needs RMB tens of millions of yuan, which not only requires a lot of foreign exchange, but also is restricted by international technical barriers.
As the backbone enterprise of the national equipment industry, Wuzhong has the responsibility and mission to develop and replace imported domestically produced equipment, especially for the key industries to develop the technological equipment that users urgently need, and play an important role in the national backbone. At the same time, this is also the direction that Wuzhong pursues to revitalize the national equipment manufacturing industry and accelerate the pace of technological innovation.
Wuzhong independently developed a CNC gantry drilling machine
After more than a year of hard work, Wuzhong Group CNC Milling Machine Co., Ltd. has developed a new special machine tool with complete independent intellectual property rights--ZK5540 CNC gantry mobile multi-head drilling machine. Recently, the equipment has passed the user's pre-acceptance and received favorable comments. At present, this equipment will be sent offline to users, which will play an important role in solving the key complex processes in the manufacturing process of nuclear power equipment in China.
