BORING BAR CONSTRUCTED BY BENDING |
摘要 |
<p>BORING BAR CONSTRUCTED BY BENDING A pair of boring bars are constructed from a single double length straight bar by providing a central bend of suitable angle and curvature to provide a pair of offset supports for a pair of cutting inserts having cutting points projecting to an offset cutting position relative to the periphery of the bar. Cutting out a small segment at the center of the bend provides two boring bars with curved ends. Machining of a chip clearance path and insert pocket on one side or the other of each bar completes a pair of left or a pair of right or opposite hand boring bars.</p> |
