Vorrichtung zur zerspanenden Bearbeitung

摘要

An external reamer has a cutting head 11 having two claws 15, 16 projecting parallel to the axis from a base 12. On one claw 15 is fastened a cutter plate 28, whose axially parallel cutting edge 32 is directed radially inwards in order accordingly to machine a cylindrical outer side of a workpiece. On the other claw 16 a guide strip 45 is detachably fastened by means of at least one clamp screw 57, so that its guide surface 48 lies, diametrically opposite the cutting edge, against the outer side of the workpiece and stabilizes the machining operation. This guide strip 45 is capable of fine adjustment in the radial direction by means of a pressure screw 63. The detachability of the guide strip 45 has the advantage that the surface of the guide face 48 can be produced without problems separately from the cutting head 11 and with any desired shape. A plurality of similar guide strips may be distributed around the circumference.
