To meet the markets need, ACL Company assimilates the new world techniques to develop the plasma cutting machine series. The plasma cutting machine is of two types: ACL-5000 and ACL-3100. Both machines consist of a main operation system and a special software system. The control system uses an industrial computer. The cutting software is of two types: universal sheet cutting software FASTCAM and specific duct former software LANTEK. Its specification can be seen below. The frame is of welded steel construction, with a vibration coil to reduce internal stress, thus the frame is of good quality. X axis adopts high precision cycle guide and Y axis adopts high precision line guide, which can reduce moving resistance. X axis and Y axis have been tested to be installed by multi-function equipment, in order to guarantee two guides straight tolerance is less than*0.05mm and vertical tolerance of X axis and Y axis are less than*0.05mm. The industrial operation system works in windows either in English or Chinese, which can be changed easily. The maximum work speed of X axis and Y axis is 8m/min. The industrial computer uses standard CNC language and can be programmed by hand. Accoring the precision,the plasma driving system is one of three types:ACL-2000,ACL-3100 and ACL-5000.Both ACL-3100 and ACL-5000 use digital communicating servo system of world famous brand. The electrical engineer adopts high magnetism and lanthanon materials, magetoconductivity and cooling capability are good. The resolving rate of coder is higher controlling precision. ACL-2000 adopts walking electrical engineer to guarantee site which requies little on cutting precision
