Sunnen's PG-Series bore gages are especially useful for fast, simple, economical process control in a lean manufacturing environment, the company says. The gages do not need electrical or air connections, making them immune to fluctuation in line voltage or air pressure. These gages can be mounted right at machining stations, and unique gaging fixtures enable 2-minute setup, while eliminating the need and expense for plug gages, mikes, jo blocks, and so on. The speedometer-type scale provides readouts down to 0.000050" for 100-percent inspection of machining operations or fast sampling of large vendor lots.
These bore gages can be used to examine the entire bore for diameter, taper, barrel, bell mouth, out-of-round and lobing. A sliding faceplate with adjustable stops permits end-to-end examination of bores. Stops can be set to allow examination of a particular section of the bore, with accuracy right up to the edge of ports, lands and ends.
