B24C
ABRASIVE OR RELATED BLASTING WITH PARTICULATEMATERIAL
Definition statement
This subclass/group covers:Abrasive or related blasting with particulate material, whereby a blast of anyparticles or pellets dispersed in air, gas, or liquid ( or an equivalent jet ofparticles or pellets projected or energised by other means ) is used for thetreatment of surfaces or cutting of materials, the particles usually being ofabrasive material.
Blasting with jets acting as abrasive jets, but not containing particulatematerial in the case of deburring, removal of extended surface areas and jetmilling of local recessions like e.g. grooves.
Relationship between large subject matter areas
- Abrasive machining
Subclass B24B of grinding and polishing complements the abrasive blastingwith particulate material, which is covered by B24C.Polishing or abradingsurfaces by means of tumbling apparatuses or other apparatuses in which thework or the abrasive material is loose, are covered by main group B24B31/00.Abrading internal surfaces, e.g. of a tube or a flow channel, byoperations in which a plastically deformable grinding compound is used as aloose abrasive material under the influence of pressure, known in the art asabrasive flow machining, extrude honing or hydro-erosive machining, iscovered by group B24B 31/116 when the dynamic viscosity of the carriermedium is higher than that of conventional fuels such as diesel. When thedynamic viscosity of the carrier is less than or equal to that of conventionalfuel (e.g. when water is used as a carrier), the machining is considered asparticulate blasting of an internal surface, which is covered by B24C 3/325and its subgroups.
- Spraying or atomising, nozzles
Spraying or atomising in general and nozzles in general are covered bysubclass B05B.
Nozzles specially adapted for blasting surfaces with a jet of particulatematerial are covered by group B24C 5/04.
- Abrasive materials and polishing compositions
Abrasive particles, powders or compositions in general are covered by groupsC09K 3/14 and C09G 1/00. Polishing compositions in general when theycontain abrasives or grinding agents are covered by C09G 1/02. When usedas materials for abrasive blasting, they are covered by B24C 11/00.
