CPC Definition - Subclass B24C
This place covers:
Abrasive or related blasting with particulate material, whereby a blast of any particles or pellets dispersed in air, gas, or liquid ( or an equivalent jet of particles or pellets projected or energised by other means ) is used for the treatment of surfaces or cutting of materials, the particles usually being of abrasive material.
Blasting with jets acting as abrasive jets, but not containing particulate material in the exceptional cases of deburring, removal of extended surface areas and jet milling of local recessions e.g. grooves.
- Abrasive machining
Subclass B24B of grinding and polishing complements the abrasive blasting with particulate material, which is covered by B24C.Polishing or abrading surfaces by means of tumbling apparatuses or other apparatuses in which the work or the abrasive material is loose, are covered by main group B24B 31/00.Abrading internal surfaces, e.g. of a tube or a flow channel, by operations in which a plastically deformable grinding compound is used as a loose abrasive material under the influence of pressure, known in the art as abrasive flow machining, extrude honing or hydro-erosive machining, is covered by group B24B 31/116 when the dynamic viscosity of the carrier medium is higher than that of conventional fuels such as diesel. When the dynamic viscosity of the carrier is less than or equal to that of conventional fuel (e.g. when water is used as a carrier), the machining is considered as particulate blasting of an internal surface, which is covered by B24C 3/325 and its subgroups.
- Spraying or atomising, nozzles
Spraying or atomising in general and nozzles in general are covered by subclass B05B.
Nozzles specially adapted for blasting surfaces with a jet of particulate material are covered by group B24C 5/04.
- Abrasive materials and polishing compositions
Abrasive particles, powders or compositions in general are covered by groups C09K 3/14 and C09G 1/00. Polishing compositions in general when they contain abrasives or grinding agents are covered by C09G 1/02. When used as materials for abrasive blasting, they are covered by B24C 11/00.
