A general-purpose precision internal grinding machine with push-button analog control that maximizes the benefits of manual operation; both new and remanufactured machines are eligible for the "Monozukuri Subsidy."
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.
