Cutting Machine : 1.Six CNC axes(Left/Right,Front/Rear,Up/Down.Rotation,Torch-Twisting,Torch-Lifting)perform cutting pipe profile.And also perform successive cutting by program,that is to connect many cutting conditions into one program so as to successively perform complex cutting process for body-pipe.branch-pipe end etc. 2.Self-centering chunk for automatic clamping pipe.no any manual clamping 3.Pipe upper-surface touch-sensor and pipe side-surface touch-sensor for detecting the pipe deflection such as roundness and straightness at cutting position ,and automatic adjust torch according to pipe conditions for getting a good cutting precision. 4.Independent torch-lifting axes can make compensation for torch position ,which ensures the relative position between torch and pipe for improving cutting quality. 5.Adjustable support-rollers can be up or down by screw,which make operation simple and reliable 6. Date input by touch screen.Only input the parameters about cutting speed,every axial speed can be automatically adjusted without any manual operation.The machine has origin-repositioning and safe-detecting functions.If any abnormality control system will be automatically locked and give some prompts for avoiding wrong operationg.Max.99 cutting conditions can be recorded.
