Thank you for visiting our company website and the Ipros site regularly. We have renewed our company page on Ipros to provide you with more information about our company. <Renewal Points> 1. We have expanded the images on the product and service pages. 2. Our products will be regularly featured in Ipros original special features. (The next features will include the "High-Performance Metals Special" and the "Ceramics Special," starting on April 8.) We will continue to strive to deliver information, and we appreciate your continued support.

We have started handling the optical material polishing polyurethane block "IC OPTIC Puck." IC OPTIC Puck is a urethane pad with a fine pore structure recommended for polishing flat and spherical optical materials. It can be used with high-speed CNC and spindle polishing equipment. Due to its ease of processing, it allows for reshaping into spherical forms and groove machining at the customer's location. It is recommended to use it with a low-viscosity dispersion type slurry. If you are having trouble polishing optical materials with sudden radii or other difficult shapes, please feel free to contact us.

On April 1, 2023, the Labor Safety and Health Regulations were revised, and the SiC (silicon carbide) abrasive particles contained in waterproof grinding paper were designated as "carcinogenic substances," requiring that work records and health examination results be preserved for 30 years. Additionally, protective gear such as goggles and gloves must be worn during work. Due to these requirements, an increasing number of users are considering alternatives to waterproof grinding paper containing SiC abrasive particles. Why not take this opportunity to switch to the diamond grinding pad "PLATO"?

We have renewed the catalog in conjunction with the product renewal of the diamond grinding pads "SQUADRO." If you wish, please download it from the catalog page for your use. 【Renewal Details】 *Applicable to SQUADRO-G2/M2/H2. ■ A new manufacturing process allows for quicker delivery times. ■ We can now provide pads in a single piece with outer diameters ranging from 200 to 1,200mm. * Sizes larger than this will be provided in multiple pieces that are bonded together. * We will manufacture to sizes tailored to customer specifications. 【Product Lineup】 SQUADRO-G2: A pad suitable for materials such as glass and lithium tantalate. SQUADRO-M / M2: Features a medium-hard bond that retains abrasive grains, making it suitable for precision grinding of metals, ceramics, and glass. SQUADRO-H / H2: Retains abrasive grains with a hard bond, making it suitable for precision grinding of hard materials and ceramics. SQUADRO-O / OWH: A pad specialized for precision grinding of optical materials. There is a relatively large abrasive grain size O, and sizes up to 1μm for OWH.

Diamond grinding pads are sheet-like grinding tools that secure diamond abrasives to metal plates or urethane pads. They are used by adhering them to the polishing plates currently in use. In recent years, they have gained attention as an alternative to free abrasives from the perspective of environmental impact and maintenance. In this experiment, we investigated the grinding rate and surface roughness on sapphire samples, which are difficult-to-grind materials. The results showed that both the 'PLATO' and 'SQUADRO' grinding pads were effective, with the PLATO-40 µm demonstrating a very high grinding rate. The possibility of achieving sapphire grinding with fixed grinding pads, a long-standing challenge in the industry, is now becoming clearer. If you are interested, please feel free to contact us through the inquiry form.

The diamond grinding pad "SQUADRO" is a sheet-like grinding tool that fixes diamond abrasives to a metal plate or urethane pad. It is used by attaching it to the polishing plate you are currently using. In recent years, it has gained attention as an alternative to free abrasives from the perspective of environmental impact and maintenance. This time, we used "SQUADRO-G" with particle sizes of 15μm, 30μm, and 45μm to process commonly used glass materials (blue plate glass, quartz glass, BK7 glass) and aluminum nitride, investigating the grinding rate and surface roughness Ra. ★ Summary of Results: Various Glass Materials Changing the particle size of SQUADRO-G from 15μm to 30μm significantly increases the processing rate. It is recommended to start with the 30μm size, which offers a good balance between rate and roughness. ★ Summary of Results: Aluminum Nitride The processing rate increases in proportion to the particle size of SQUADRO-G. It is recommended to start with the 30μm size, which offers a good balance between rate and roughness. If you are interested, please feel free to contact us through the inquiry form.
