Used LECO GR-20 #9005508 for sale

LECO GR-20 is a comprehensive wafer grinding, lapping and polishing equipment designed for processing and characterization of a wide range of semiconductor and optoelectronic materials. The system is capable of achieving high levels of precision in surface preparation for research preparation and analytical sample preparation processes. GR-20 unit offers a range of grinding, lapping and polishing options, allowing the user to tailor the machine to the specific sample requirements. The tool's grinding component consists of a tilted diamond wheel for scratch-free surface preparation. The wheel is pneumatically driven and uses a pneumatically operated clamping mechanism to securely hold the sample wafer in place during grinding. LECO GR-20's lapping component utilizes a heated table to hold a rotating, spring-loaded mirror lap. The mirror lap forces the lapping liquid over the sample during lapping, which creates a highly efficient and uniform surface without the risk of scratching the sample. This process results in a smooth, uniform surface that meets the highest grade levels. The polishing process of GR-20 involves using LECO-PLAS VIVA automatic polishing head, which is designed to produce highly consistent and repeatable results. The polishing head utilizes diamond-impregnated discs to ensure precise polishing of the sample surfaces. The asset's built-in water atomization model keeps the environment clean during the polishing process. LECO GR-20 equipment also features a proprietary software package for material characterization. This software package includes modules for advanced materials analysis, surface finishing simulation, sample characterization, and 3D parametric mapping. All of these features are integrated into a single user-friendly process control system. GR-20 is a robust, reliable unit that is easy to use and offers a range of grinding, lapping, and polishing procedures for the most demanding research and analytical sample preparation applications. It is designed to enable users to achieve the highest levels of precision and repeatability.
