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.

The smallest general-purpose precision internal grinding machine in the YIG series is the YIG-15SA model. It has a proven roundness measurement of 0.07μm. The spindle and grinding wheel spindle have a lower center height of 1080mm, which is highly appreciated as it allows the operator to lean in and easily operate the handles and levers while observing the machining conditions. Additionally, one operator can work with 2 to 3 machines simultaneously. The SA model offers a choice between a "semi-automatic grinding cycle" for processing single items and a "fully automatic grinding cycle" for continuous processing of identical items. It is suitable for small-batch production of various types, ranging from 100 to 300 pieces. The spindle swivel angle of the YIG-15SA is +5° (half angle). The workpieces to be ground are expected to be straight items such as automotive parts, motorcycle components, and electrical parts, with small and short inner diameters.

The YIG-15SA is a large model, and the YIG-20M is a model designed solely for "semi-automatic grinding cycles" for individual items. It has a maximum grinding range of 200φ, which is 50φ larger, and the spindle can tilt by +15° (half-angle) as standard. It is favored by tool factories and grinding processing companies for grinding gauges and jigs. The center height of the spindle and grinding wheel spindle is 1120mm. Like the YIG-15SA, the YIG-20M is also designed for easy operation of handles and levers while leaning in to observe the processing situation, which is highly appreciated. It is suitable for grinding a variety of small quantities.

The YIG-15SA is one of the larger models. The YIG-20MSA has a maximum grinding range of 200φ, which is +50φ larger, and the spindle can tilt by +15° (half-angle) as standard. It is favored by tool factories and grinding processing companies that perform grinding of gauges and jigs. The center height of the spindle and grinding wheel spindle is 1120mm. Like the YIG-15SA, the YIG-20MSA is designed to allow the operator to lean in and easily operate the handles and levers while observing the processing situation, which is highly appreciated. Additionally, it allows one operator to work with multiple machines, typically 2 to 3 units. The MSA model offers a choice between a "semi-automatic grinding cycle" for processing single items and a "fully automatic grinding cycle" for continuous processing of identical items. It is suitable for low-volume production of various types, typically 100 to 300 pieces.

Based on the YIG-15 and YIG-20 series, which have already achieved a shipment record of 3,100 units to date, the YIG-40 has been designed to process large and heavy workpieces with high precision. ********* Notice ******** We are currently developing a new series, the IRINO INTERNAL GRINDING (IIG), which includes the large general-purpose precision internal grinding machines IIG-40 and IIG-40SA based on the YIG-40. If you are looking for a large general-purpose precision internal grinding machine or if you already own a YIG-40 and are considering remanufacturing, please contact Irino Kiko.

What is a "keray"? In English, it is called a "lathe dog" (lathe = turning machine, dog = gripping tool) or "lathe carrier." It is said that the singular form "carry" of this carrier became colloquially known as "keray" in Japan. By the way, in German, it is referred to as "Drehherz," which means "rotating heart." In Inuno Kiko, we manufacture and sell kerays. Please feel free to contact us.
