FEATURES  OF FLAT DIAMOND LAPS:

• Diamond laps are circular grinding discs manufactured from high-quality commercial-grade RVD diamond grits, which are electroplated uniformly and firmly.
• The hardest naturally occurring stone available on earth is diamond. This quality of diamond makes Diamond laps the most effective for faceting, grinding, and lapping all kinds of gemstones.
• They feature a standard 1/2” arbor hole.
• They come with a PSA backing plate so that the diamond grinding disc can be easily attached to a backing plate. You have the option of buying an Aluminium backing plate variant in conjunction with the diamond laps available here.
• The steel plate has a surface width of  0.5mm thickness.
• They come in two diameters 6” and 8” as a standard product. However, we provide customisation of sizes on request. Contact us to place a custom order.
• They feature grit size from #80 to #3000, giving you the choice of coarsest grits.
• Water is the best choice as a lubricator for diamond grinding discs during the process of grinding, faceting, or lapping the gemstones.

ADVANTAGES OVER OTHER DIAMOND GRINDING DISCS:

• The diamond grits are embedded with a Nickel electroplating process. Nickel is an element that resists erosion. Hence, these diamond grinding discs do not wear away and provide a clean surface for lapping.
• Electroplated flat diamond laps allow you durability and freer grinding, faceting, and polishing process.
• These diamond grinding discs help obtain a flat surface finish on the gemstones. It ensures that there are no semi-reflective or dull grey surfaces while polishing them at a later stage.
• The surface of the lap, which is composed of steel, has a rigid and robust structure. This provides strength and sturdiness to the diamond laps.
• They are produced with such precision that they are fixed perfectly parallel to the surface. This flat lap provides a smooth surface for balanced and accurate operation.
•  These diamond laps do not require any dressing and hence save you the time and effort.
• Diamond abrasives on the laps produce grinding results faster and in fewer cycles than the other laps.

WORKING GUIDE OF DIAMOND GRINDING DISCS:

• To begin with cutting or grinding, where high stock removal is desired, lower grit diamond grinding discs should be preferred. They are aggressive and aid in grinding the gemstones rapidly. The next step where precise and fine grinding is required, finer grit diamond lap should be chosen for the purpose. So the grit size of the diamond laps should be considered based on the gemstone’s value and grinding purpose. We recommend using finer grit flat diamond laps for expensive gemstones so there is minimum wastage of the stone.
• They can be installed either vertically on any suitable lapidary equipment or horizontally on flat lap machines as per your need. To avoid any kind of wobbling of the diamond grinding discs while working, you must ensure that the lap is mounted properly and according to the directions.
• The ideal running speed of the diamond lap should be between 1800RPM - 3000 RPM, which should be decided as per your grinding requirements.
• A sufficient amount of lubrication with water is beneficial while grinding gemstones as it enhances the grinding/lapping process and yields a finer surface finish. It also eliminates overheating of the diamond grinding disc during the process.
• In order to achieve superior results while grinding gemstones, it should be ensured that the diamond grinding disc is clean and dust-free. It avoids the possibility of obtaining minutest patches or scratches on the gemstones.

USER GUIDE/THINGS TO KEEP IN MIND:

• Best results from these lapidary polishing laps for faceting are obtained when you put the least pressure while polishing valuable gemstones such as Emerald, Quartz, Jade, Garnet, etc. It should be such that constant contact is maintained. High pressure could lead to scratches and chipping away of the top polished layer.
• The surface of the polishing lap should be constantly lubricated with water to keep the surface moist, as heat is absorbed in the process. Hence, the lap will work efficiently for a longer time.
• You need to be aware of the type of compound of the polishing and faceting lap that will be ideal for your choice of gemstone. It varies according to the hardness and type of stone. Chromium oxide is utilized best for polishing gemstones such as Emerald, Quartz, Garnet, Jade, Beryl, Tourmaline, Peridot, Feldspar, and other similar stones.

• It is imperative to always keep the gemstone and polishing lap clean to achieve a superior quality of shine and polish of the gemstone.
• The room chosen for lapping should also be free of any dust to avoid even the minutest of scratches and dirt from the gemstone.
• We suggest that the lap speed should be moderate, i.e. around 1500 RPM as high speed leads to more stock removal of the gemstone being polished.
• The dressing of the lap should be done carefully to achieve a true plane surface as it determines the quality of the polished stone.
