In the CNC machine tool industry such as pipe bending machines and hydraulic pipe bending machines, in the adverse market environment of low-price competition, many domestic manufacturers and brands are not outstanding, lack technological innovation, rely heavily on foreign advanced technology, and lack core competitiveness. At the same time, rising labor costs and raw materials have also greatly increased the cost pressure on many companies.

Although my country's pipe bending machine industry started relatively late, supported by the demand from downstream machining and other related industries, the industry as a whole has developed rapidly and its scale has continued to grow. But for now, many companies are still operating in an extensive business model, although their strength has improved. Due to excessive competition and severe product homogeneity, profit margins are narrow and the development of many companies is constrained. So how to obtain an automatic pipe bending machine with relatively little investment is a question worth exploring. Is it possible to upgrade the original machine tool without buying a fully automatic pipe bending machine? The answer is yes. The experience of upgrading and transformation over the past few years tells us that this has great potential. It not only has good practical performance and short cycle, but also can save a lot of money.

What kind of machine tools are suitable for CNC upgrading and remanufacturing? Experience has proven that upgrading vertical and horizontal lathes (especially large vertical and horizontal lathes), gantry milling to CNC gantry milling, gantry planers to CNC gantry milling, horizontal boring and milling machines to CNC horizontal boring and milling machines, and vertical and horizontal grinders to CNC grinders are more effective.

CNC upgrading and transformation must first redesign and remanufacture the mechanical part of the machine tool to make it meet the requirements of CNC. Simply adding servo motors and CNC systems will not achieve the purpose of upgrading. To this end, the following work is generally required:

Replace the original trapezoidal screw with a ball screw to improve accuracy and reduce friction. Grind, scrape, and plastic guide rails, or directly use linear rolling guides to refine the spindle system. Design an automatic cooling chip removal system to improve spindle accuracy. Improve the automation of the machine tool. If necessary, add a tool change mechanism—the tool magazine robot designs and manufactures an automatic lubrication system.

In the transformation process, the CNC system and servo system must be determined and selected. The more functions a CNC system has, the better. Systems with more functions are generally more expensive. Domestic systems and imported systems should be selected according to needs. At present, there is still a gap between domestic systems and imported systems. For large-scale high-precision equipment, it is generally better to choose imported systems. However, domestic systems have made great progress in recent years and can be used reliably on general lathes and milling machines. Servo motor First choose AC servo motor.

The choice of remanufacturing CNC upgrading contracting company is also very important. It is necessary to choose a company that has passed the qualification certification. The current remanufacturing industry is still very unstandardized. The prices charged by different companies for the same machine tool modification vary greatly, sometimes as much as - times. The existing performance of the surveying and contracting company must be inspected on-site by the contracting company. Those companies that do not have a fixed site and a stable technical team cannot engage in remanufacturing. A good remanufacturing company must have strong mechanical and electrical design capabilities and certain processing and manufacturing capabilities.
