What is boring tool

About the classification of tools

In the machining process, hole machining tools are an indispensable part of machining, including drills, reamer drills, boring cutters, reamers, internal surface broaches, etc. Compared with other machining methods, boring machining is considered to be a more challenging process. It relies only on adjusting a single blade (or tool holder) to machine micron-level holes, such as H7 or H6.

A boring tool is a cutting tool used for boring holes, commonly used for internal hole machining, hole enlargement, and internal contour profiling. It consists of one or two cutting parts and is specially used for roughing, semi-finishing or finishing existing holes. Boring tools can be used in boring machines, lathes or milling machines.

The shape of the cutting part of a single-groove boring tool is similar to that of a turning tool. In order to make the size of the hole high, the fine-tuning boring tool can accurately adjust the size of the hole on the machine tool. It has a dial engraved with precise scale lines, and the dial and the spindle equipped with the boring head form a pair of precision screw nut mechanisms. When the nut rotates, the spindle with the boring head can move linearly along the direction key. Due to the precise scale reading, the accuracy can reach 0.001 mm.

The double-edged boring tool has two teeth distributed on both sides of the center, cutting at the same time. Since the radial force generated during cutting is balanced, the cutting amount can be increased and the production efficiency is high. Double-edged boring tools are divided into floating boring tools and fixed boring tools according to whether they float on the boring bar. Floating boring tools are suitable for precision machining of holes. Their essence is similar to that of reamer, and they can process holes with high dimensional accuracy and smooth surface.
