Tube facing machine

摘要

A cutter (11) for facing ends of tubes has a cutting edge (13) perpendicular to the axis of a drive shaft and extending obliquely from a plane containing a reference side face of the cutter (11). The cutter has a base end portion fitted in a cutter mount groove (100) which is defined by a reference side face a specified distance away from the drive shaft (4) axis. The cutter is positioned as shifted a predetermined distance along the length of the groove, with the cutter reference side face bearing on the groove-defining reference side face, whereby the cutter is adapted to cut the tube end (T) in a direction a predetermined angle outward with respect to a tangential direction of the tube at the cutting position.
