84.65 - Machine-tools (including machines for nailing, stapling, glueing or otherwise assembling) for working wood, cork, bone, hard rubber, hard plastics or similar hard materials. 8465.10 - Machines which can carry out different types of machining operations without tool change between such operations - Other : 8465.9 1 - - Sawing machines 8465.92 - - Planing, milling or moulding (by cutting) machines 8465.93 - - Grinding, sanding or polishing machines 8465.94 - - Bending or assembling machines 8465.95 - - Drilling or morticing machines 8465.96 -- Splitting, slicing or paring machines This heading covers machine-tools for the shaping or surface-working (including cutting, forming and assemblin ) of wood (and materials derived from wood , cork, bone, hardened rubber, hard plastics an similar hard materials (horn, corozo, mother o pearl, ivory, etc.). d 7' The heading excludes machines for workin materials which although referred to in the heading do not possess the characteristics of hard materia s at the time work commences on them. For this reason, machines for cutting or slicing supple plastics or unhardened rubber are excluded (heading 84.77). Furthermore, the heading does not cover machines for making articles fiom granules or powder, such as machines for moulding lastic materials (heading 84.77), machines for agglomerating or mouldin i or other ligneous matter (heading 84.79) or other similar machtnes. Althoug particles or fibres of woo! they might be considered to be for the treatment of the materials mentioned in the headmg, the headng also excludes, in general, machines and apparatus whose function is not to work the material or its surface, e.g., those for the drying of wood or the ageing of it by desiccation (heading 84.19), machines for the expansion of cork (headmg 84.19) or machtnes for compressing, agglomerating or impregnating wood (heading 84.79). 'i % In general, machine-tools are power-driven but similar machines, worked by hand or edal, are also covered by this heading. These latter types can be distin ished fiom the han tools of heading 82.05 and from the tools for worlung in the hand of eading 84.67, by the fact that they are usually designed to be mounted on the floor, on a bench, on a wall or on another machine, and are thus usually provided with a base plate, mounting frame, stand, etc. X ftu (A) MACHINES NOT NORMALLY SPECIALISED FOR A PARTICULAR INDUSTRY This group includes : (1) Sawing machines of all types. They operate by means of blades or chains generally provided with teeth.

These machines carry out several machining operations and have automatic tool change, from a magazine or the like in conform@ with a machining programme. Consequently, this group covers machine-tools which carry out two or more machining o erations by automatic tool change from a magazine or the like, whereas machine-too s which carry out one machining o eration using a single tool or several. tools working simultaneously or sequentially ( or example, muItxple-spindle drills or multiple-cutter rnillin machines) remain classified in their respective subheadings as drilling or milling rnac$,,es. f P (5) Grinding, sandin and polishing machines. Grinding machines which use grindstones are principally use for hard products such as corozo, hard rubber, horn and ivory. f Sanding machines use abrasives to improve the surface finish as well as the dimensional accuracy of the wor iece. This group includes those with an oscillating action, belt sanders, disc sanders, obbin and drum sanders. Machines known as smoothing machines are also in this group. "g Polishing machines impart a lustre, by means of bands, dnuns or flexible rollers, to a workpiece previously given a smooth finish.

(c) Fragmenting machines which produce small pieces of wood of similar size and shape. These include sliver cutting machines, particle producing machines, wood-wool making machines and chopping and chipping machines. However, defibrators for producing wood pulp are excluded and fall in heading 84.39. (d) Paring or slicing machines which use a straight cutting ed e to produce thin sheets either by slicing (machines for making thin boards) or y paring (machines for producing veneers or thin sheets for plywood production). % This group also includes veneer shearing machines which use rectilinear blades, mitre trimming machines and mullion cutting machines. (11) Lathes, which are used to fashion a worlcpiece by a motion about its own axis, the tool not turning.

The headin also includes machines which can carry out different types of machining operations without too change between such operations. f Examples are : (1) Combined joine machines having in a single unit several machines with different functions, used in ependently of each other. With this type of machine it is necessary to ive manual assistance to the wor iece between each operation. These include machines for surface planing cornbin2 with one or more other operations and sawing-moulding-morticing machines. (2) Multi-purpose machines in which, unlike the previous group, no further manual assistance is required after the insertion of the workpiece. These include single-end tenoning machines with several spindles, double-end tenonin machines, machines for ositiom hardware, dowel holes, etc., machines for assemb ing, using adhesives and Enisling @or the production of veneer stnps or making panels fiom laths).
