The debut of the 【Hybrid Precision Internal Grinding Machine IIG-20H】, which offers versatile usability and efficient grinding comparable to NC machines.
By incorporating Renishaw's absolute scale and solenoid valve into Mitsubishi Electric's touch panel sequencer control, we have achieved ultra-high precision with roundness of 0.3µm to 0.4µm, while maintaining the advantages of general-purpose operation with handles and levers. This allows for digital representation of positional relationships equivalent to NC machines, reducing the burden on operators and enabling efficient high-precision grinding. Previously, real-time numerical data could not be viewed, and adjustments relied on the craftsman's tactile sense, with measurements taken after polishing to determine values. The hybrid precision internal grinding machine IIG-20H offers significant improvements compared to the existing YIG model: - In a standard grinding process, the total time has been reduced by 75 seconds out of 210 seconds (35% time reduction). - Additionally, in setup, a time reduction of 143 seconds out of 180 seconds is possible (79% time reduction). - For difficult-to-cut materials, the dressing interruption function further shortens grinding time. This hybrid precision internal grinding machine meets customer needs for precision grinding and production efficiency.

Company information
Irino Kiko Co., Ltd. (a full member of the Japan Precision Machinery Manufacturers' Association) manufactures precision internal grinding machines capable of processing difficult-to-cut materials and meeting high precision requirements. We have achieved roundness of 0.07μm, generally maintaining levels around 0.1 to 0.2μm for machine deliveries. Professional engineers are continuously developing and manufacturing products in areas such as the main body of internal grinding machines, spindle axes, jigs, and electrical control. We manufacture, sell, and repair general-purpose and hybrid precision internal grinding machines, large general-purpose precision internal grinding machines, NC precision internal grinding machines, spindle axes (grease-lubricated and oil mist-lubricated), and rotating tools (Kere). We also have a track record of developing, manufacturing, and selling special internal grinding machines tailored to specific workpieces. Currently located in the Kurihama industrial area of Yokosuka City, we will be relocating to the Yokosuka Research Park (YRP) in October 2025. https://yrp.co.jp/ Planned construction site: 7-3 Hikari no Oka, Yokosuka City, Kanagawa Prefecture Our professional engineers, specializing in the manufacturing of internal grinding machines and machine tools, will continue to support the industry and meet your needs.
