TRI-ROLL THREAD COMPARATOR

THREAD CHECK COMPARATORS: • System offers actual measurements of dimensional characteristics for quicker machine adjustments during thread production • Reduces gaging time over thread plug and ring gages • One single gage can be used for pre-plate, after-plate class 1, 1A, 2, 2A, 3, 3A eliminating the need for multiple fixed limit thread plug and ring gages • Ideal for use with Statistical Process Control – SPC • Rigid construction and constant measuring pressure provides consistent and accurate readings • Quick setting with the use of a set master • Easy to setup rigid construction and constant measuring pressure of our tri-roll thread comparators provide consistent and accurate readings. Fixed mounting of the lower rolls assures a solid support for the work piece. Only the upper roll actuates the indicator thereby providing repeatable readings. The instrument is easy to set as no adjustment of the lower rolls is required when changing from one thread size to another. The variable gaging system provides longer life of the tooling and thus reduces costs. Thread Check’s Tri-Roll Thread Comparators comply with system 21, system 21A, and system 22. Thread Check, Inc. offers an extensive range of Tri-Roll Thread Comparators. Tri-Roll Thread Comparators provide actual thread measurements of dimensional characteristics for quicker machine adjustments during thread production. The Tri-Roll System measures the exact position of the pitch diameter within the tolerance range. It also checks size and out of roundness of plain cylindrical parts. The Tri-Roll reduces gaging time over thread ring gages. One single gage can be used to inspect pre-plate, after-plate, class 1, 1A, 2, 2A, 3, and 3A eliminating the need for multiple fixed limit thread ring gages. The
