Abstract

PURPOSE:To enhance measuring accuracy and to prevent the damage of the leading end of a cutting tool, by providing a plurality of micrometer heads to perform measurement in the same state as an actually rotating state. CONSTITUTION:At first, the leading end of a cutting tool 4 attached to a tool holder 3 is brought into contact with the anvil of a micrometer 10(A) to read graduations. When the bite holder 3 is rotated in this state, the blade chip of the cutting tool 4 is damaged and, therefore, the micrometer head 10(A) is escaped from the cutting tool 4. In the next step, the bite holder 3 is rotated by 180 deg. and the leading end of the cutting tool 4 attached to the tool holder 3 is read from graduations by the anvil of a micrometer head 10(B).

特徴とする。In the present invention, the precision of the rotational diameter of the fly cutting tool is improved by measuring it in the same state as when it actually rotates, and after making contact with the tip of the cutting tool which is an anobile for measurement, the annobil is rotated 180'. It is characterized by not damaging the tip of the bite because it allows it to escape from the bite.

First, contact the anvil of the micrometer 10 (A) with the tip of the tool 4 attached to the hide holder 3 and read the scale. In this state, when the tool holder 3 is rotated, , since the tip of the cutting tool 4 will be damaged as in the conventional case, the micrometer head 10 (A) is released from the cutting tool 4. Then, the cutting tool holder 3 is moved to 180 mm.
Rotate it and read the scale with the anvil of the micrometer head 10 (B) at the tip of the tool 4 attached to the tool holder 6. By performing the above operations, the rotation diameter of the rotary tool can be determined with certainty without damaging the cutting edge of the rotary tool. In addition, micrometer spatula 10 (A).
