Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the hole diameter, improve accuracy, reduce surface roughness, and can also better correct the deflection of the original hole axis.
Boring is divided into general boring and deep hole boring. General boring can be done on an ordinary lathe. The boring tool can be fixed on the tailstock of the lathe or on a small tool rest. Deep hole boring requires a special deep hole drilling and boring machine. The boring tool needs to be equipped with a boring stem, and a hydraulic pump station is required to use coolant to remove iron filings.
