Definitions
- the present invention concerns to a tool for grinding and polishing of glass, especially glass jewelry stones, and surfaces of hard and brittle non-glass materials.
- abrasive grains are formed for example by eerie oxide (Ce0 2 ) and the bond is for example organic phenol-formaldehyde or melamin- formaldehyde resins.
- a filler for example perlite or ash is used.
- a tool for grinding and polishing of glass and surfaces of hard and brittle non-glass materials comprising abrasive which is for example eerie oxide, and bond, for example phenol-formaldehyde resin, substance of the tool consisting in that it further comprises as a filler hollow or full or porous polyamide and/or polyethylene and/or polypropylene and/or polymethacrylate and/or polystyrene and/or glass and/or corundum microbeads of size of 1 ⁇ m to 200 ⁇ m.
- abrasive which is for example eerie oxide
- bond for example phenol-formaldehyde resin
- the tool comprises 100 parts by weight of eerie oxide of medium grain size of 30 ⁇ m as abrasive, 20 parts by weight of phenol-formaldehyde resin of novolac type as bond and 5 parts by weight of corundum microbeads of medium size of 20 ⁇ m.
- the tool comprises 100 parts by weight of eerie oxide of medium grain size of 6 ⁇ m as abrasive, 20 parts by weight of phenol-formaldehyde resin of novolac type and 6 parts by weight of polyethylene microbeads of medium size of 55 ⁇ m.
- a substantially higher removal is achieved with the tool and thus time necessary to perform an operation of grinding or polishing is reduced while achieving a fully satisfying quality of the worked surface of product.
- Advantage is also an increased life of the grinding or polishing tool.
- Tool is made of a mixture comprising 100 parts by weight of eerie oxide of medium grain size of 30 ⁇ m as abrasive, 20 parts by weight of powder epoxy-modified phenol-formaldehyde resin of novolac type as bond and 5 parts by weight of corundum microbeads of medium size of 20 ⁇ m.
- the mixture is wetted with 4 parts by weight of distilled water, sifted through screen, compacted into form of a wheel and cured under temperature of 140°C to 180°C.
- the tool is to be used mainly for glass grinding.
- Example 2 Example 2
- Tool is made of a mixture comprising 100 parts by weight of eerie oxide of medium grain size of 6 ⁇ m as abrasive, 20 parts by weight of powder phenol-formaldehyde resin of novolac type and 6 parts by weight of polyethylene microbeads of medium size of 55 ⁇ m.
- the mixture is wetted with 4 parts by weight of distilled water, sifted through screen, compacted into form of a wheel and cured under temperature of 120 °C to 180 °C.
- the tool is to be used mainly for glass polishing.
- Tool is made of a mixture comprising 100 parts by weight of eerie oxide of medium grain size of 4 ⁇ m as abrasive, 20 parts by weight of powder epoxide resin of dian type with 2 % of hexamethylene tetramine and 4 parts by weight of polystyrene microbeads of medium size of 90 ⁇ m.
- the mixture is wetted with 4 parts by weight of distilled water, sifted through screen, compacted into form of a wheel and cured under temperature of 120°C to 180°C.
- the tool is to be used mainly for glass polishing.
- Tool for grinding and polishing of glass can also be used for grinding and polishing of surface of hard and brittle non- glass materials.
