Indexable Boring Tool Usage and Precautions

When installing the tool, pay special attention to cleaning. Boring tools, whether rough or finishing, in the installation and assembly of all aspects, must pay attention to cleanliness. The assembly of the tool holder and the machine, the replacement of the blade, etc., must be wiped clean, and then installed or assembled

The tool is pre-adjusted, its dimensional accuracy, good condition, must meet the requirements. Indexable boring tool, in addition to single-blade boring knife, the general does not use artificial cutting method, so the pre-processing is very important. The size of the pre-adjustable must be accurate, should be adjusted in the lower limit of tolerance, and consider the temperature factors, to amend, compensation. The tool presetting can be carried out on a special presetter, on a knife or other instrument.

After the tool is installed, the dynamic beating check is performed. The dynamic beating check is a composite indicator that reflects the accuracy of the machine spindle, the tool accuracy, and the tool and machine tool connection accuracy. If this accuracy is greater than 1/2 or 2/3 of the accuracy required by the machined hole, it can not be processed. It is necessary to find out the cause and eliminate it before proceeding. This operator must keep in mind and strictly enforce it. Otherwise the processing of the hole can not meet the requirements.

The life of each part of the tool should be determined by means of statistical or testing to ensure the reliability of machining precision. For a single-blade boring tool, this requirement can be lower, but for multi-blade boring knife, this is particularly important. Indexable boring tool is characterized by: pre-adjustable knife, a processing to meet the requirements, must ensure that the tool is not damaged, otherwise it will cause unnecessary accidents.
