Glossary of terms used on this site
| Term | Definition |
|---|---|
| abrasive |
any material or substance used for grinding, polishing, etc., such as diamond in various grit sizes. |
| aggregate |
any of various loose, particulate materials, such as sand, coral, gravel, or pebbles, added to a cementing agent to make concrete. |
| arbor |
axis that holds, or supports a rotating cutting tool or grinding wheel. |
| bevel |
a surface that does not form a right angle with adjacent surfaces. |
| bond |
a substrate that binds, fastens, confines, or holds together. The bond determines the rate at which the substrate is worn down to expose new layers of diamond. The bond is the prime factor when selecting a tool based on a materials’ hardness and or abrasiveness. |
| bore |
the inside diameter of a hole, such as a bushing or bearing. |
| bushing |
a replaceable thin tube or ring, usually of bronze, mounted on a blade to reduce arbor size. |
| carbide |
a hard material made of compacted binary compounds of carbon and heavy metals, used to make tools that cut metal and other hard materials. |
| cement |
a building material made by grinding calcined limestone and clay to a fine powder, which can be mixed with water and poured to set as a solid mass or used as an ingredient in making mortar or concrete. |
| chamfer |
a cut that is made at a 45° angle to the adjacent principal face. |
| CNC |
computer numerical control - a processor based machine that permits the automation of cutting, grinding, shaping and polishing on stone. |
| composite |
a complex material, such as fiberglass, in which two or more distinct, structurally complementary substances combine to produce structural or functional properties not present in any individual component. |
| concrete |
an artificial, stone like material used for various structural purposes, made by mixing cement and various aggregates, such as sand, pebbles, gravel, or shale, with water and allowing the mixture to harden. |
| countersink |
a tool that cuts a slopped depression at the top of a hole to permit a screw head or other object to rest flush with the surface. |
| earth magnet |
An object that is surrounded by a magnetic field and that has the property, either natural or induced, of attracting iron or steel. |
| electroplating |
the process of coating a surface of a conducting material with diamond particles. This is a nickel bond. |
| engineered stone |
Engineered stone is a composite material comprising rock and resin. It is used primarily for kitchen countertops. |
| face |
flat surface of a slab. |
| fiberglass |
a material consisting of extremely fine filaments of glass that are combined in yarn and woven into fabrics, used in masses as a thermal and acoustical insulator, or embedded in various resins to make boat hulls, fishing rods, and the like. |
| glass |
a hard, brittle, noncrystalline, more or less transparent substance produced by fusion, usually consisting of mutually dissolved silica and silicates that also contain soda and lime, as in the ordinary variety used for windows and bottles. |
| grain |
the arrangement or direction of the pattern in a stone. |
| granite | |
| hybrid |
a specially formulated diamond pad that is a mix of resin and metal or ceramic. It is close to a metal in grinding ability but with a much more subtle scratch pattern. |
| limestone |
a sedimentary rock consisting predominantly of calcium carbonate, varieties of which are formed from the skeletons of marine microorganisms and coral: used as a building stone and in the manufacture of lime. |
| lippage |
generally refers to two pieces of material joined together but one edge is higher or lower than the adjoining material, causing unevenness on a flat surface. |
| magnet |
an object that is surrounded by a magnetic field and that has the property, either natural or induced, of attracting iron or steel. |
| mandrel |
a shaft or shank which is inserted into a work piece to hold it during machining. |
| marble |
metamorphosed limestone, consisting chiefly of recrystallized calcite or dolomite, capable of taking a high polish, occurring in a wide range of colors and variegations and used in sculpture and architecture. |
| PCD |
polycrystalline diamonds - offer hardness, strength and abrasion resistance of natural diamond without its susceptibility to fracturing. It is manufactured using man-made diamond particles that are grown together in a high pressure, high temperature process. At the same time, these particles are integrally bonded to a cemented tungsten carbide substrate for mechanical strength and impact resistance. |
| plastic |
any of a group of synthetic or natural organic materials that may be shaped when soft and then hardened, including many types of resins, resinoids, polymers, cellulose derivatives, casein materials, and proteins. |
| quartz |
a very hard mineral composed of silica found commonly in granite. |
| resin |
a viscous liquid capable of hardening composed of a wide variety of synthetic substances. |
| scratch pattern |
the pattern etched into a floor by a diamond tool. The more aggressive the tool, the more evident the scratch pattern. The more even a scratch pattern is, the easier it is to progress through various grits to grind and polish a floor. |
| segment |
a strip, piece or wedge of sintered material fixed to a base or body. The segments are composed of diamond crystals and powdered metal which form the bond, or ‘matrix’. |
| silicate |
any of the largest group of mineral compounds, as quartz, beryl, garnet, feldspar, mica, and various kinds of clay, consisting of SiO2 or SiO4 groupings and one or more metallic ions, with some forms containing hydrogen. Silicates constitute well over 90 percent of the rock-forming minerals of the earth’s crust. |
| sintering |
to form a coherent mass by heating without melting. The mass includes evenly distributed powdered metal and diamond in various grits. |
| slab |
a lengthwise cut of a quarry block of stone commonly 20mm and 30mm in thickness. |
| slurry |
a thin mixture of a liquid, especially water, and any of several finely divided substances, such as cement, plaster of Paris, or clay particles. |
| swarf |
an accumulation of fine particles of metal or abrasive cut or ground from work by a machine tool or grinder. |
| swirl |
the Spirograph etching or shadow that can result from using a machine with imperfect or low-quality polishing, resin, or buffing pads. |
| synthetic diamond |
a term to describe diamond crystals manufactured under similar conditions to that of natural diamonds. |
| terrazzo |
a mixture of chips or pieces of stone and cement and is polished when in place |
| transfer |
when regular resin pads are improperly formulated for heat tolerance, the resin in the pad melts onto and is forced into the floor. This can cause discoloration and leave imperfections in a polished concrete floor. This can also occur with the plastic in post resin pads. |
| travertine |
a form of limestone porous in nature due to deposits from ground or surface waters. |
| vacuum brazing |
a material joining technique performed inside a vacuum chamber at temperatures ranging between 1000⁰C to 2500⁰C |
| water channels |
grooves created by raised segments designed to evacuate swarf and water. |
