Abstract
The present invention is directed to a method and apparatus for polishing stone and synthetic substrates. The apparatus uses a leather polishing pad to apply a finish to a stone or synthetic substrate. The pad has a specially designed fluid channeling pattern which cools by maintaining a quantity of liquid polishing slurry centrally of the pad for cooling purposes. The grit and amount of the abrasive used with the slurry varies based on the mechanical properties of the substrate.
Description
- The present invention relates generally to polishing tools. More particularly, the invention relates to a method and apparatus for polishing synthetic materials.
- Polishing tools for finishing natural and man made surfaces such as counter tops and stone floors have made a few advances in recent years. This is due to the fact that while natural stone has been used for many years for both aesthetic and functional reasons, it has only been in recent years that a variety of synthetic stone products have been available.
- Chief among these synthetic materials is quartz. While quartz is a strong and durable material, finishing, repairing, and polishing it remains a challenge. Standard methods for polishing quartz and other synthetic produce unacceptable results for various reasons. For example, sandpaper and other polishing methods will tend to leave fine swirl patterns which adversely affect the quality of the finish. Also, other polishing methods will tend to produce localized heating which can actually melt and destroy certain synthetics. The open cell rubber and foam polishing pads generally used for stone are known to create damaging hot spots.
- The present invention is directed to a method and apparatus for polishing stone and synthetic substrates. The apparatus uses a leather polishing pad to apply a finish to a stone or synthetic substrate. The pad has a specially designed fluid channeling pattern which cools by maintaining a quantity of liquid polishing slurry centrally of the pad for cooling purposes. The grit and amount of the abrasive used with the slurry varies based on the mechanical properties of the substrate.
- It is a major object of the invention to provide an improved method and apparatus for polishing stone and synthetic stone materials.
- It is another object of the invention to provide an improved apparatus for polishing synthetic stone materials.
- It is another object of the invention to provide an improved method and apparatus for polishing stone and synthetic stone materials which dissipates heat.
- It is another object of the invention to provide an improved method and apparatus for polishing stone and synthetic stone materials which has a novel foam backing pad.

- Referring now to
FIGS. 1-4C the apparatus is shown. It can be seen that thepolishing pad 10 is actually a composite of several components which are enclosed within anouter covering 20. In a preferred embodiment, theouter covering 20 is made of a natural animal hide such as pigskin, preferably garment quality. The use of leather for theouter covering 20 takes advantage of the fact that the natural porosity of leather in combination with the tendency of leather to soften when moist reduces swirl patterns and reduces heat build up.Outer covering 20 is formed of two separate circular pieces ofleather - A significant problem with finishing synthetic materials such as quartz is that they are actually formed of granular material, e.g., granular quartz, which is held together by a resinous material. This resinous material can melt, deform, or discolor from the heat of sanding using conventional finishing methods. The present invention reduces the risk of localized overheating by controlling or confining the liquid abrasive slurry used for finishing. This is accomplished by way of two intermediate polishing pad components. The first of these components is a spirally arranged, segmented
water control component 30. Thiscomponent 30 is segmented into a plurality offluid controlling sections 32, thespaces 34 between the sections creating fluid flow channels. The component may be a one piece component but may preferably be formed as a series of controlling sections or “slices”. Thechannels 34 extend generally spirally from the center of thecomponents 30, and widen gradually as can be seen inFIG. 3 . For a sixinch diameter pad 10, channels should start at about 0.16 inches in width and increase to about 0.42 inches at theperiphery 36. These widths will increase or decrease with increasing or decreasing diameter of thepad 10. The relative spacing ofsections 32 is maintained by affixing them, as by adhesive, to backingcomponent 38. 3M® high strength 90 adhesive may be ideally used for this purpose. -
Backing component 38 is made of a flexible but water impervious material, the water impervious capability helping to retain liquid within the pad during finishing. Component may be made of e.g., a flexible plastic such as polypropylene. Also, more fluid will flow throughchannels 34 with a water impervious layer positioned beneath them as this layer will not absorb any of the fluid to be channeled for cooling purposes. - It can be seen that both
components central apertures outer coverings apertures components Apertures -
FIGS. 4A-4C show afoam buffing pad 50. The buffing/polishing pad 50 is used to polish the binding polymer of any engineered/composite stone material. In a preferred embodiment, open cell rubber is used forbuffing pad 50. A problem with prior art buffing pads is the tendency of the pad to “bridge” the surface of the substrate being polished, that is, the prior art pads could not directly contact the underlying polymer of the substrate, the polymer situated just below the surface formed by the granules of, e.g., quartz. It can be seen that thepad 50 has a series of perpendicular scoring marks 52 formed thereon forming a grid with an array of raised portions. This configuration allows thepad 50 to contact the underlying polymer directly by breaking the surface tension to produce an even luster during the buffing phase of the polishing method of the invention. - In use, once the user has attached polishing
pad 10 to the sander (not shown) a liquid abrasive slurry is applied to the substrate, which again may be quartz. When the sander is operated and thepad 10 is on the substrate, some moisture from the substrate will be forced up throughapertures channels 34 creating a cooling effect. Thepad 10 is effective from 3,000 grit powder up to 14,000 grit powder. In accordance with the inventive method, thepad 10 may be used with a relatively coarse grit to start and then succesively finer grit in successive steps until a desired finish is attained. After each use of thepad 10, thebuffing pad 50 is used to polish.
