When installing the tool, pay special attention to cleaning. Whether the boring tool is roughing or finishing, attention must be paid to cleanliness in all aspects of installation and assembly. The assembly of the tool holder and the machine tool, the replacement of the blade, etc., must be wiped clean, and then installed or assembled, and must not be done carelessly.
The tool is pre-adjusted, and its dimensional accuracy and perfect condition must meet the requirements. Indexable boring tools, except for single-edged boring tools, generally do not use manual trial cutting methods, so pre-adjustment before processing is very important. The pre-adjusted size must be accurate, adjusted to the middle and lower limits of the tolerance, and corrected and compensated considering the temperature factor. Tool presetting can be carried out on a special presetter, on-machine tool setter or other measuring instruments.
The dynamic runout check is performed after the tool is installed. The dynamic runout inspection is a comprehensive index, which reflects the accuracy of the machine tool spindle, tool accuracy and the connection accuracy between the tool and the machine tool. If the accuracy exceeds 1/2 or 2/3 of the required accuracy of the machined hole, the machining cannot be performed. It is necessary to find out the reason and eliminate it before proceeding. The operator must keep this in mind and strictly implement it.
