3408 Machining Centers and Way-Type
Note-The following definitions apply to
, refers to
a multipurpose numerically controlled
machine tool for the complete and auto-
matic machining of parts requiring mul-
tiple operations such as milling, drilling,
tapping, boring, and reaming, having an
integral tool storage device and an inte-
gral means for positioning various faces
of the work piece. It must have facilities for
automatic interchanging of varied cutting
tools between successive operations. Ex-
cluded from this class are multipurpose
numerically controlled machine tools,
such as Boring-Drilling-Milling Machines,
which require the use of an attachment or
accessory for tool storage and/or to posi-
tion the various faces of a work piece.
These types of equipment are classified
in other appropriate classes within group
, refers to a
special machine tool of station type de-
sign consisting of individually mounted
self-contained machining units and facili-
ties for indexing the work piece to each
station in a predetermined sequence.The
machining unit(s) may be disassembled
and rearranged to accommodate differ-
ent work piece configurations. Machine is
capable of performing single or multiple
operations on the work piece simulta-
neously or in sequence to each station.
