Keltech is a technology development company specializing in high speed abrasive lapping and polishing of high-end products such as sapphire (cell phone windows, watch crystals, computer screens), industrial components (precision-fit seals), and wafer polishing (semiconductor and solar). Keltech has a very large patent portfolio along with one-of-a-kind prototype machines used for demonstrating high speed abrasive polishing of sapphire wafers and industrial components. The system uses fixed-abrasive diamond particle media to provide extremely high increases in productivity, large cost reductions, and clean operations (messy abrasive slurry is eliminated). Keltech has also developed the unique abrasive disks that are required for the high speed lapping and polishing machine.
