China Makes Advances in Metal Forming Machine Tools
China is spectacular to the machine tool circle, being the world's largest consumer looking for more and more advanced products. As a machine tool producer, it is spectacular too, trying to catch
up with the world's advanced level in both metal cutting and metal forming machine tools.
With respect to metal forming machine tools in particular, the overall performance of Chinese products has stepped forward in 2007, delivering such medium to high end features as CNC, high precision and high performance, Wang Chunsheng of Jinan Casting & Metal-forming Machinery Research Institute writes in a Chinese article for Adsale
Industry Portal.
CNC turret punch
For instance, Jiangsu Yawei Machine-Tool Co Ltd launches two 300 KN CNC turret punches, Models HPI-3048 and HPI-3044, with core technology and main components supplied by Nisshinbo of Japan. Hubei Sanhuan (Huangshi) Metalforming Equipment Co Ltd launches two 200 KN CNC turret punches, Models Parma 1225 and Verona 1225. They are actually the latest products from LVD/Strippit of Belgium.
CNC punching-shearing machine
The PS31250 CNC hydraulic punching-shearing machine from Jinan Zhuduansuo Jiemai Machinery Co Ltd delivers nominal forces of 300NG (punching) and 280KN (shearing) with Fanuc 18i CNC system.
The position of top and bottom dead centers can be automatically set. The gap between cutting tools is programmable. The shift between punching and shearing processes is automatic. In addition, the automatic programming software provided can optimize the toolpath, marker making, and so on, thereby increasing processing efficiency and saving materials.
Jiangsu Jinfangyuan CNC Machine Co Ltd's APSS type CNC punching-shearing machine is equipped with the hydraulic system drive from Bosch-Rexroth, as well as an intelligent clamp which can be programmed for automatic displacement. It also features an alert function to report falling off of metal sheets from the machine.
CNC laser cutting machine
With respect to CNC laser cutting machine, Mr Wang writes flying optics is presently the mainstream technology used in products for China market, with an increasing emphasis on dynamic acceleration.
Automatic process optimization is ensured by high performance CNC systems and built-in software. In addition, efforts are put in to enhance safety, ergonomics, user-friendliness and network
connectivity. Major new models include the LCF-1530 from Jinan Zhuduansuo Jiemai Machinery Co Ltd and LC6-3015 from Jiangsu Jinfangyuan CNC Machine Co Ltd.
CNC folding machine
Jiangsu Jinfangyuan CNC Machine Co Ltd launches a 1,000KN CNC folding machine, Model PR100x3100. It features a synchronized electric-hydraulic servo technology and a hydraulic system of integrated
design. A Delem DA69W CNC control system is used. Jinan VOLSZ Numerically Controlled Machinery Co Ltd launches its patented 300KN pneumatic folding machine Model AB-3012. With pneumatic-driven rams, it delivers benefits like low noise, fast speed, and energy saving.
Mechanical press
Xuzhou Metalforming Machine Factory launches a 800KN high-speed precision pressing line, comprised of a JF75G-80A press and an auto leveler cradle. It features high strength, high dynamic
precision, and high motion stability.
High-pressure waterjet
Following an increasing awareness in environmental protection, more Chinese machine tool builders are investing in the development of high-pressure waterjets. One of them is Dardi International
Corporation, which develops a gantry-type high-pressure waterjet Model CPJISER55.
