Boring is a high-precision, single-point cutting finishing process. Its primary value is performing geometric correction and size refinement on existing holes to achieve tolerances of IT6 or better. Unlike drilling, boring utilizes a single-point adjustable boring bar and the machine's high-rigidity system to reliably eliminate geometric errors like positional and straightness deviations left behind by preliminary operations. Boring types include through-hole (for uniform diameter), line boring (for co-axiality), and face boring (for perpendicularity). The process is executed on highly rigid platforms, such as CNC Machining Centers, Horizontal/Vertical Boring Mills, and dedicated Fine Boring Machines.
