摘要：
A boring holder in a tool radius adjusting system is provided with a cutting blade and fine and coarse motion adjusting mechanisms each capable of adjusting the position of the cutting blade relative to a rotational axis of the boring holder. The tool radius adjusting system is provided with a tool radius measuring device for measuring the tool radius of the boring holder and a controller configured to calculate a compensation amount based on a tool radius measured by the tool radius measuring device and a target tool radius and to operate the fine and coarse motion adjusting mechanisms based on the compensation amount so that the tool radius is brought into agreement with the target tool radius.
