Description

A boring tool is a type of cutting tool used for boring, commonly employed in internal hole machining, hole enlargement, and internal contour imitation. It consists of one or two cutting parts, specifically designed for the rough, semi-finish, or finish processing of existing holes. Boring tools can be utilized on boring machines, lathes, or milling machines.

The shape of the cutting part of a single flute boring tool is similar to that of a lathe tool. To achieve high dimensional accuracy for the hole, a fine adjustment boring tool can precisely adjust the bore size on the machine tool. It has a dial with a precise scale line, and the dial, along with the spindle containing the boring head, forms a pair of precision lead screw nut mechanisms. When the nut is rotated, the spindle with the tool head can move in a straight line along the directional key. With the precision of the scale readings, the accuracy can reach 0.001 millimeters.

The selection of boring tools is greatly restricted by the part’s hole diameter and length (depth and overhang). The general principle is to choose the shortest overhang and the largest possible tool size. Selecting the right tool, applying it correctly, and reliably clamping it can minimize tool deflection and vibration.
