METHOD FOR MOUNTING TOOL WITHOUT DEVIATION

摘要

PROBLEM TO BE SOLVED: To provide a method capable of high precisely adjusting the insertion depth of a tool while keeping the advantage of a cost by simplification of a structure of a tool receiving part, and capable of eliminating restriction of a material of the tool receiving part and the tool. SOLUTION: When the tool 13 is coaxially inserted in the tool receiving part, a movable contact piece 25 is brought into contact with the free end of the tool, and the tool is stretched between the contact piece and reaction force 33 acting in a hole 11 of the tool receiving part in the direction opposite to the inserting direction of the tool before heating is started. After the nominal dimension s is achieved, heating is stopped when a shaft 12 is inserted in the hole of the tool receiving part.
