ʫ ʫ ʫ Bore Gages ˙ Applications Two-Step Inner Diameter Measurement (different diameters) The inner diameter of two locations with different diameters can be simultaneously measured (judged). This is ideal for automatic measure- ment immediately after machining. BG-03 Inner Diameter Measurement of Small/Large End Holes in Connecting Rods Two holes can be simultaneously measured and two-direction measurement can be performed (Model BG-03 / BG-04). BG-10A-503 Cylindrical Inner Diameter/Taper Measurement Precise measurement of diameter at one loca- tion is performed. The measuring point can be moved to measure the taper at two locations (A, B). BG-10A-501 Inner Diameter Measurement of Piston Pin Holes Two pin holes are sequentially measured, and two-direction measurement can be performed (Model BG-03 / BG-04). BG-10A-502 Inner Diameter Measurement of Transmission Cases Insertion measurement for inner diameter at two locations on one side and one location on the opposite side can be performed. BG-04 ɾBG-10A High Precision These heads provide the high precision required for inner diameter post-process measure- ments. Diverse Measurements Measuring heads are available for a diverse range of measurements, including one diame- ter, two diameters, ellipse, average diameter, hole with steps and taper. Superior Cost Performance Standardization of the main unit, guide, fingers and contacts has eliminated the necessity of new designs for most parts. This has allowed us to produce them more quickly and inex- pensively. Complete Easy Mount Options The components that support the measuring head such as the floating relieving unit and relieving unit are also standardized. This eliminates damage to the measuring unit do to machining errors and improper positioning. No Air to Control Since the unit is driven by electricity, management of the measuring air is not required. ˙ Features Inner-Diameter Measuring Head for Post-Process BG-10A Machine Control Gage Measuring Heads
