Boring holes. The manufacturing process of a snap ring groove using a radial caliper on a horizontal boring machine is shown.
Boring - the process of machining the inner surfaces of a hole with boring cutters to a predetermined size . It is mainly carried out on turning , aggregate , boring and other groups of metal-cutting machines . Boring is one of the most complex metalworking operations. The diameter of the hole to be machined can range from a few millimeters ( Screw-cutting lathe ) to several meters ( Carousel-turning ). Boring also provides for all kinds of technological notches, chamfers, grooves, sharpening at different angles, etc. [1]

Boring on lathes, as a rule, is carried out in the following cases:
- if drilling , coredrilling or reaming do not provide the necessary accuracy of hole sizes;
- if there is a need to ensure the straightness of the axis of the hole and the accuracy of its position;
- if there is no drill or countersink of the required size;
- if it is necessary to process a hole whose diameter exceeds the largest standard diameters of drills and countersinks;
- with a small length of the hole.
Boring Tool
A boring tool is a technological device that consists of three main parts:
- replaceable non-rotatable plate;
- body of the boring mandrel;
- shank.
