Analysis of the status quo and prospect of CNC milling machine

In recent years, benefiting from the great environment and strong market demand of the national revitalization equipment manufacturing industry, the domestic milling machine manufacturer has experienced a long-term development of technology and high investment enthusiasm. The “Twelfth Five-Year Plan” has taken the revitalization of equipment manufacturing industry as the main content to promote the optimization and upgrading of industrial structure, and CNC milling machine has become one of the key points of revitalizing the equipment manufacturing industry. In the future, China will focus on the development of high-speed, precision, composite CNC gold-cut milling machines; heavy-duty CNC gold-cut milling machines; CNC special-purpose milling machines; large-scale CNC forming stamping equipment and related parts of CNC milling machines.

This year, China's economic development has slowed down, and the lack of industrial growth has had a major impact on the entire processing center industry. The negative effects of overcapacity in the modern society and the processing center industry are beginning to emerge. In the next stage, the industry will absorb a number of small manufacturers, eliminate a group of backward enterprises, transfer a batch of processing centers to foreign countries, and improve product quality through mergers and acquisitions. This not only solves the problem of overcapacity, but also improves the overall level of the processing center industry.

The downturn in the market has also brought opportunities for transformation for machine tool companies. Enterprises should shift their main focus from selling products to improving the quality of products, re-setting product lines, formulating development battles, eliminating outdated products, and developing more. A profitable machining center is ready for the market to pick up.

CNC milling machine structure

1, cooling system. The cooling system of the machine tool is composed of a cooling pump, an outlet pipe, a return pipe, a switch and a nozzle. The cooling pump is installed in the inner cavity of the machine base, and the cooling pump drives the cutting fluid from the reservoir in the base to the outlet pipe, and then The nozzle is ejected to cool the cutting zone.

2, lubrication system and method. The lubrication system is composed of a manual oil pump, oil separator, throttle valve, oil pipe and the like. The machine tool adopts the periodic lubrication method, and uses the manual lubricating oil pump to lubricate the main shaft sleeve, the vertical and horizontal guide rails and the three-way ball screw through the oil separator to improve the service life of the machine tool.

CNC Milling Machine

From the characteristics of digital control technology, since the effect control machine tool adopts the servo motor, the digital technology is used to realize the direct control of the working sequence and motion displacement of the machine tool. The gearbox structure of the traditional machine tool is cancelled or partially canceled, so the mechanical structure It has also been greatly simplified. Digital control also requires mechanical systems with high transmission stiffness and no drive clearance to ensure control command execution and control quality. At the same time, due to the continuous improvement of computer level and control capability, it has become possible to allow more functional components to perform various auxiliary functions at the same time on the same machine tool, so the mechanical structure of the CNC lathe machine tool has higher integration function than the traditional machine tool.

From the requirements of the development of manufacturing technology, with the emergence of new materials and new processes, and the demand for low cost in the market competition, metal cutting is moving towards higher cutting speed and precision, higher production efficiency and system. More and more reliable development. This requires CNC machine tools developed on the basis of traditional machine tools to have higher precision, drive power is more too, work is more reliable, can achieve long-term continuous operation and as little downtime as possible.
