摘要

#CMT# #/CMT# The centre (1) has two distant chucks (3, 4) e.g. hydraulic locking collet chuck, for gripping a section to be machined (2) through their ends, and mobile on a frame (12) extended along a longitudinal axis (x). A frame overhang support (17) carries a machining tool (6) e.g. trimming cutter, through a displacement unit permitting displacement of the tool along transverse and vertical axes (y, z). A follower rest (7) is arranged relative to the tool and has a jaw (8) e.g. rotating motor, angularly positioning the section, which slides inside the jaw, where the jaw has a surface made of PTFE. #CMT#USE : #/CMT# Centre for machining a section i.e. work piece. #CMT#ADVANTAGE : #/CMT# The follower rest is arranged relative to the machining tool and has jaw angularly positioning the section, thus avoiding bending of the section in a machining zone during machining of the section, and hence ensuring precise and rapid machining of the section of large length. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a machining centre. x : Longitudinal axis y : Transverse axis z : Vertical axis 1 : Machining centre 2 : Section to be machined 3, 4 : Chucks 6 : Machining tool 7 : Follower rest 8 : Jaw 12 : Frame 17 : Frame overhang support.
