Walking center machine, also known as walking center CNC lathe,originated in Germany and Switzerland. In the early days, it wasmainly used for precision machining of Jungong instruments. Withthe continuous development and expansion of industrialization, dueto the urgent market demand, it was gradually applied in theprocessing of civilian products; Japan and South Korea developedsimilar machine tools earlier than China, mainly focusing on theuse of Jungong in the early stages. After the war, they graduallybecame widely used in the manufacturing industry with the demandfor development; Subse, Taiwan, China introduced thistechnology and independently developed this type of e withdifferent processing needs. The manufacturing of CNC centrifugalmachines in China started relatively late. Due to technologicalclosure and policy restrictions, before the 1990s, China'scentrifugal machines mainly relied on imports to meet processingneeds. With the continuous development of automation and strongmarket demand, a large number of powerful CNC centrifugal machinemanufacturers emerged in the Chinese market. Among them, thisseries of machine tools were produced in coastal areas such asGuangdong, Nanjing in Jiangsu, Shandong, Liaoning, and Xi'an inmainland China, and achieved good market applications, filling thedomestic gap. Compared with conventional CNC machining processes,composite machining has prominent advantages mainly manifested inthe following aspects:
(1) Shorten the product manufacturing process chain and improveproduction efficiency. The combination of turning and milling cancomplete all or most of the processing steps in one clampingprocess, greatly shortening the product manufacturing processchain. On the one hand, this reduces the production auxiliary timecaused by card loading changes, while also reducing themanufacturing cycle and waiting time of tooling and fixtures, whichcan significantly improve production efficiency.
(2) Reduce clamping times and improve machining accuracy. Thereduction in card loading frequency avoids the accumulation oferrors caused by positioning benchmark conversion. At the sametime, most of the turning and milling composite processinge has the function of online detection, which can achievein situ detection and accuracy control of key data in themanufacturing process, thereby improving the machining accuracy ofthe product.
(3) Reduce land area and lower production costs. Although thesingle unit price of turning and milling composite processinge is relatively high, due to the shortening of themanufacturing process chain and the reduction of e re the product, as well as the reduction of the number offixtures, workshop area, and e maintenance costs, it caneffectively reduce the overall investment in fixed assets,production operation, and management costs.
