Thread-View Technology Measures Up

It is a common challenge for operators of thread measurement methodologies: to identify new technologies that can improve the repeatability, accuracy and speed of measurements. They've been asking what they can do to reduce thread-plug calibration, product inspection and manufacturing process control costs. They also have been exploring ways to better comply with ISO, industry, government and customer specifications without adding to labor and equipment costs, and to better ensure they produce or purchase dimensionally conforming threaded products. Quality control and metrology has not seen a breakthrough technology for thread measurement since supermics and optical comparators, the most widely used technologies in the marketplace today, according to Stanley Johnson, executive vice president of The Johnson Gage Co. (Bloomfield, CT) and president of Johnson Thread-View Systems LLC. "We've now found a way to take a 100-year-old tradition in thread measurement and move it giant steps ahead with more accurate reporting of data and less cost in the measurement of screw threads."
