B23B TURNING; BORING
Introduced: September 1968
Classification Context
- Section:
- PERFORMING OPERATIONS; TRANSPORTING
- Class:
- MACHINE TOOLS; METAL-WORKING NOT OTHERWISE PROVIDED FOR
- Subclass:
- TURNING; BORING
Description
B23B covers machine tools and processes for turning and boring operations on workpieces, typically metals. This subclass includes lathes, boring machines, and related equipment designed to remove material through rotational cutting, as well as accessories, tool holders, and control systems integral to these operations. Turning operations produce cylindrical or tapered surfaces, while boring creates or enlarges holes; both may be performed on a single machine tool. Adjacent subclasses address other metal-working operations such as milling (B23C), grinding (B23D), and sawing (B23H).
Filing statistics
IPC subclass B23B recorded 180,015 patent applications worldwide between 2013 and 2023. Annual filings grew from 10,228 in 2013 to 19,259 in 2023 (+88%), peaking at 25,132 applications in 2020. The most active applicants in class B23 are ITW (ILLINOIS TOOL WORKS) (3,407 applications), FANUC (3,120 applications) and DISCO ABRASIVE SYSTEM (2,777 applications).
