Introducing our copper flat polishing laps, engineered to meet the demands of professionals in the ceramics, glass, and crystal industries. With a range of sizes available, these laps offer versatility and reliability for all your polishing needs.

Our copper flat polishing laps are designed to provide efficient and effective polishing for a range of materials, including ceramics, glass, and crystal. Available in a variety of sizes, including 6 inch copper lap, copper flat laps, and 8 copper flat laps, our products are perfect for pre-polishing or final polishing.Our copper laps feature a 1mm and 3mm rolled copper face that is laminated to a 6mm thick aluminum master lap, ensuring a true turning surface. These traditional laps are designed to be charged with diamond powder and are compatible with most types of polishing compounds.Compared to zinc polishing lap, tin polishing lap, and chrome oxide polishing lap, our copper flat laps offer superior grinding performance and durability. Additionally, our copper flat laps with master lap can be re-machined if it becomes damaged, contaminated, or worn with use.Whether you're a professional lapidary or an amateur enthusiast, our copper flat laps are the perfect choice for achieving a high-quality finish on even the most delicate and brittle materials.

Key Characteristics:

  1. Copper Base: The copper flat laps typically consists of a flat, circular, or square copper base that provides stability and durability to the tool.

  2. Diamond or Other Abrasive Coating: The working surface of the copper flat laps is coated with diamond grit or other abrasive materials. Diamond is often used due to its hardness and durability, making it effective for grinding and polishing gemstones and minerals.


Uses:

  1. Gemstone Cutting: Lapidarists use copper flat laps to shape and facet gemstones. The abrasive surface of the flat lap helps create precise facets and angles on gemstones, enhancing their brilliance and sparkle.

  2. Cabochon Making: Cabochons are polished, domed gemstone shapes with a flat base. Copper flat laps are used to shape and polish cabochons to achieve a smooth, glossy finish.

  3. Mineral and Rock Polishing: Geologists and collectors use copper flat laps to polish mineral specimens and rocks. This process can reveal the natural beauty and patterns within the specimens.

  4. Lapidary Art: Artists and craftsmen use copper flat laps for various lapidary art projects, such as creating custom jewelry pieces with polished gemstones.

  5. Fossil Preparation: Paleontologists and fossil enthusiasts use flat laps to carefully remove rock and matrix from fossils while preserving the delicate fossil material.

  6. Glass and Ceramics: In addition to lapidary work, copper flat laps can also be used for shaping and polishing glass and ceramics.

  7. Metalworking: Some metalworkers use copper flat laps with abrasive coatings for finishing and polishing metal surfaces.


Copper flat laps are versatile tools in the lapidary and mineralogical fields, providing precise control over shaping and polishing processes. They are available in various sizes and configurations to accommodate different lapidary tasks and are essential for achieving professional-quality results in gemstone cutting and lapidary artistry.

FAQ

Q:Why can copper not be charged?
Copper rod cannot be charged easily by friction because it is a conductor, only non-conducting material gets charged by friction.
Q:What are the advantages of lapping?
What are the benefits of lapping? The main reasons to utilize precision lapping services include control over thickness identity, surface finish, part uniformity, flatness, camber reduction, parallelism and preparation for polish.
Q:How accurate is the lapping process?
Lapping is a low-pressure machining process used to increase the dimensional accuracy and surface finish of the workpiece. The lapping process uses fine Abrasive particles to perform cutting action on the surface of the workpiece. Tolerance is kept in lapping is 0.01 mm.
Q:What are the disadvantages of lapping process?
The result of the surface by conventional lapping is always matte gray. Its advantage is the lower price of the abrasive, but the disadvantages are the large variance of the size of the abrasive grains, less hardness, less service life, high consumption, and thus waste.
Q:What material is best for lapping?
Diamond: Diamond is the hardest material known and has a sharp, angular structure. Diamond is extremely useful in lapping and polishing due to it's removal rates and surface finishing qualities. Diamond can produce excellent surface finishes combined with high removal rates.
Q:What is the difference between flat honing and lapping?
Honing is specifically performed on the inner diameter (ID) of a cylindrical surface. Lapping is performed on both the ID and the outer diameter (OD) of a surface. We perform OD lapping on our roll lappers and ID lapping on our speed lathes. We can also perform manual lapping on some flat surfaces.
