Although the machine tool of my country's pipe bending machine industry started late, but supported by the needs of downstream mechanical processing and other related industries, the overall development of the industry is relatively fast, and the scale is also growing. But for now, although many companies have improved their strength, they are still in an extensive business model. Due to excessive competition and serious product homogeneity, the profit margin is narrow and the development of many enterprises is constrained. So how to obtain an automatic pipe bender with less investment is a question worthy of discussion. 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 in the past few years tells us that this is promising, not only has good practical performance, short cycle, but also can save a lot of money.

Problems that need to be paid attention to in CNC upgrade, what kind of machine tool is suitable for CNC upgrade and remanufacturing? Experience has proved that vertical and horizontal lathes (especially large vertical and horizontal lathes), gantry milling upgrade CNC gantry milling, gantry planer upgrade CNC gantry milling, The transformation effect of upgrading horizontal boring and milling machine to CNC horizontal boring and milling machine and vertical and horizontal grinding machine to upgrading CNC grinding machine is ideal.

CNC upgrade 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 numerical control systems cannot achieve the purpose of upgrading. For this purpose, the following work is generally required:

Replace the original trapezoidal lead screw with a ball screw, improve accuracy, reduce friction, grind and grind the guide rail and paste it with plastic or directly use a linear rolling guide to refine the main shaft system, improve the precision of the main shaft, design an automatic cooling chip removal system, and improve the degree of automation of the machine tool When necessary Increase the tool change mechanism - the tool magazine manipulator is designed and manufactured with an automatic lubrication system.

In the transformation, it is necessary to determine and select the numerical control system and servo system. The more functions of the CNC system, the better, and the price of the system with more functions is generally more expensive. It is necessary to choose the domestic system and the imported system according to the needs. At present, there is still a gap between the domestic system and the imported system, and the imported system is generally better for large-scale high-precision equipment. But in recent years, the domestic system has made great progress, and it can be used reliably for general lathes and milling machines. Servo motor First choose AC servo motor.

The choice of remanufacturing CNC upgrade contracting company is also very important. It is necessary to choose a certified company. The current remanufacturing industry is still very non-standard. The price of different companies for the same machine tool is very different, and sometimes the difference is as high as - times. The existing performance of the contracting company should be investigated on the contracting company's site. Those who have not Fixed sites, companies without a stable technical team cannot do remanufacturing. A good remanufacturing enterprise must have strong mechanical and electrical design capabilities and certain processing and manufacturing capabilities.
