A rotary cutter and its manufacturing method

SUBJECT of the Invention Only the cutter main body which notch|chip etc. generate|occur|produced among several cutter main bodies can be replaced|exchanged， and the exchange operation property of a cutter main body is improved. PROBLEM to be solved The rotary cutter 11 is rotatably attached to the front-end|tip part of the arm of the machine for tree debarking via the rotary axis|shaft 14. Moreover， the rotary cutter 11 is with the cylindrical cutter holding member 31 spline-fitted by the rotary axis|shaft 14， It has the cutting edge 32b which protrudes on the radial direction outer side from the outer peripheral surface of this cutter holding member 31， and provides several cutter main body 32 attached to the circumference direction at the outer peripheral part of the cutter holding member 31 so that removal was possible at predetermined intervals.
