Description

B23Q covers machine tool components, accessories, and subsystems including spindles, chucks, workholding devices, tool changers, and copying/control mechanisms. It encompasses structural details and functional arrangements of machine tools characterized by their constructional features rather than their end-product function. This subclass also includes combinations or associations of multiple metal-working machines that are not designed to produce a specific final result, such as modular machine configurations or integrated machining systems.
