REAMER CAPABLE OF FINE ADJUSTMENT OF MACHINING DIMENSION IN REAMING MACHINING

摘要

PROBLEM TO BE SOLVED: To give great effect by setting the diameter of a reamer to a machining diameter for fine dimensional adjustment according to machining conditions in reaming machining and to extend the life of a tool by adjusting a dimensional change during machining and regrinding. SOLUTION: A slit l is made in a body of a reamer and a taper and a screw are applied to an inner diameter portion 2. A sliding pin 3 is assembled in the inner diameter portion of the body and a bolt 4 is slid.
