When working, according to the prescribed procedure, the plate is positioned in the axial direction, and the die on the turntable is arbitrarily selected for punching. It is also possible to use a stepping method to punch out a large circular hole square hole or an arbitrary shape inner hole or shape with a small die. In addition, the numerical control press is combined with a laser cutting machine or a gas plasma cutting machine to form a pressure processing center. In addition to the above functions, the pressure machining center can also automatically cut and unload the parts and automatically tap the parts of the high-speed left and right automatic cutting parts of the sheet. At that time, the aircraft was an international leader in performance, but it was not promoted because of the use of a transistor digital control system, large volume reliability, and low life. Since then, due to the development of electronic technology, the development of domestic CNC presses has been almost stagnant. With the country's reform and opening up policy, the research and application of CNC presses have developed rapidly. At the same time, relevant domestic research and production units have also developed a variety of CNC presses, and gradually entered the small batch production stage. The domestic CNC presses have absorbed some advanced foreign structures and manufacturing processes, and imported key components from abroad. Therefore, they are close to the advanced foreign countries in terms of performance reliability and life expectancy, and some products have been able to replace the mouthwash. . The necessity of using CNC presses The need for new product development is mainly used for sheet metal blanking. It can directly punch out round holes or shaped holes, and can also punch any shape of inner hole or shape. It is only necessary to manufacture two or three simple mold parts for production, so using CNC presses to process sheets can save a lot of molds. The symmetrical three-roller bending machine of any specification can use this program to design and calculate. Through the implementation, it can receive three obvious effects. The operation is simple and easy to implement. It does not require the designer to understand the computer language more. It is ok to enter which basic data. (Finish)
Solid wood veneer as the main raw material, through high-frequency pressing and chairs made of different shapes. Bentwood chairs seat curved wooden multilayer board selected environmental pressing at high frequency, double-sided high-quality bendable fire board; election steel chair legs, powder coated or plated trim. Currently on the market 75% of bentwood chairs are curved wood and metal combination, modeling relatively simple, stylish. High seat bentwood chairs is very particular about, usually should be maintained at between 420-440mm, and bentwood chairs in to the desktop height should be maintained at between 280-320mm. Furthermore width should not be less than the former seat bentwood chairs of 380mm, seat depth between 340-420mm, the total height of the backrest is appropriate between 850-1000mm.
