 B23
MACHINE TOOLS; METAL-WORKING NOT OTHERWISE PROVIDED FOR (punching, perforating, making articles by processing sheet metal, tubes, or profiles B21D; wire-working B21F; making pins, needles, or nails B21G; making chains B21L; grinding B24)
 B23

Note(s)

  1. In addition to operations not provided for in any other class, this class provides, in sub-class B23P, for combinations of operations provided for in different sub-classes of classes B21-B24, with the exception of subsidiary operations performed in conjunction with main operations covered by a single sub-class.
  2. In the following elaborations:
    1. The term "metal-working" should be understood as covering the working of other materials unless the context requires otherwise.
    2. The term "kind of operation" and similar expressions relate to such metal-working operations as boring, drilling, milling and grinding.
    3. The term "kind of machine" means a machine designed for a particular kind of metal-working operation (e.g. a lathe).
    4. The term "form of machine" means a machine of a particular kind adapted or arranged for a particular way of working or for particular work, e.g. face-plate lathe, tailstock lathe, turret lathe.
    5. The term "different machines" is to be understood as covering different forms of machine for performing the same type of metal-working operation, e.g. vertical and horizontal boring machines.
  3. Sub-class B23Q comprises features, specific to machine tools, which relate to a requirement or problem of a nature which is not peculiar to a particular kind of machine tool, e.g. feeding work, although the realisation of these features may differ according to the kind of machine tool concerned.

    That sub-class provides in general for such features, even if the feature or a specific function, in any particular case, is to some extent peculiar to, or is claimed only for, machine tools designed for one particular operation; only in exceptional cases are such features to be classified in the sub-class for the machine tool concerned. Certain features of this general nature are, however, referred to sub-classes relating to particular metal-working operations, especially B23B, in which case the sub-classes in question are not restricted, in respect of those features, to the kind of machine tool with which they are primarily concerned. If details, components, or accessories have no essential feature specific to machine tools, the more general class, e.g. F16, takes precedence.
