What are the technical features of CNC machine tools?
Galvanized square wire mesh
Galvanized square wire mesh is manufactured in galvanized Iron Wire.That is mostly used as Window Screen , industrial sieves in sugar,chemical,stone crusher industries,Also in sieveing grain. Workmanship: Hot dipped galvanized before or after weaving: Electric galvanzied before or after weaving.

Square wire mesh is divided into electro galvanized square wire mesh and hot-dipped galvanized square wire mesh.
Material: Galvanized iron wire, stainless steel wire, etc.
Weaving and characteristic: Plain weaving, stable structure, good corrosion resistance and durable and so on.
Uses: Used in industry and constructions to sieve grain powder, filter liquid and gas, safety guards on machinery enclosures and so on.

Transformation of the right knife holder z-axis. Replace the original trapezoidal screw (63×10×3600 mm) with the imported Rexroth Ball Screw; remove the light bar driver and increase the servo motor drive; repair the z-axis guide rail; repair the z-axis press plate and the insert strip.
Design and manufacture of electronic control systems for machine tools. Select FANUC 0it CNC system; choose FANUC AC digital servo motor; choose domestic joint venture low voltage electronic control components; design and develop machine tool control logic diagram.
Finally, the machine tool electromechanical coupling. Debugging the machine's x-axis and z-axis; adjusting the machine's geometric accuracy; debugging the machine's coordinate accuracy and detecting the accuracy of each axis with a dual-frequency laser. Machine auxiliary function debugging and continuous operation of the machine for 36 hours.
After the transformation, the machine tool performance is stable and reliable. After more than one year of production verification, the requirements for the transformation have been achieved. The transformation cost of 1 million yuan is only equivalent to 1/15 of the purchase of CNC machine tools, saving a lot of money for users. The machine tool for the plant to produce hydropower equipment in the volute out of a strong, creating a production value of tens of millions of dollars.
The need to pay attention to the numerical control upgrade, what kind of machine tool is suitable for CNC upgrade and remanufacturing? Experience has proved that the vertical and horizontal lathes (especially large-scale horizontal lathes), gantry milling upgrade NC gantry milling, gantry plane upgrade CNC gantry milling, Horizontal boring and milling machine upgrade NC horizontal boring and milling machines, vertical and horizontal grinders to upgrade the CNC grinding machine transformation effect is ideal.
The numerical control upgrade must first redesign and remanufacture the mechanical part of the machine tool so that it can meet the requirements of numerical control. Simply adding the servo motor and the CNC system can not achieve the purpose of upgrading. Generally, the following work should be done:
Replace the original trapezoidal screw with the ball screw to improve accuracy and reduce friction; grind and scrape the guide rail and apply plastic or directly use the linear rolling guide; refine the main shaft system to improve the accuracy of the spindle; design automatic cooling chip removal system and improve machine tool automation Degree; when necessary, increase the tool changer-knife robot; design and manufacture of automatic lubrication system.
The CNC system and servo system must be determined and selected during the transformation. The function of the numerical control system is not as good as possible, and the system with more functions is generally more expensive. According to the need to choose domestic systems and import systems. At present, there is still a gap between domestic and imported systems, and it is generally preferable to use large-scale high-precision equipment as the import system. However, domestic systems have made great progress in recent years and can be used reliably for general lathes and milling machines. The servo motor first selects the AC servo motor.
The choice of a remanufactured NC upgrade contractor is also very important. To select qualified companies, the current remanufacturing industry is still not standardized, and the difference in the price of a company with different machine tools varies greatly. Sometimes the difference is as high as 2-3 times; the existing performance of the contracted company is investigated; Surveying, those companies that do not have fixed sites and do not have a stable technical team cannot remanufacture them. A good remanufactured enterprise must have a strong electromechanical design capability and must have certain processing and manufacturing capabilities.
