It is good practice to quickly verify repeatability on a MIC TRAC™ 3000 at frequent intervals between calibration periods. This simple verification process involves zeroing the MIC TRAC using TF-1F fixtures (anvils). This procedure will ensure the unit repeats to a resolution of 0.0001″ or better. Simply use the Coarse Adjust Knob to open and […]
When inspecting external functional size on a straight thread (ACME, ISO Metric, UN, etc.), some have a tendency to force the RG-7000 external roll gage onto a part. Keep in mind overly aggressive placement can cause the roll to move or completely slip from the part. Sometimes, this can slam the gage and/or hands on […]
An easy adjustment of your rails during assembly of an MRP-2001 will help you see the indicator better when inspecting external crest diameter, pitch diameter, or ovality. During setup, you simply position the rails so that any excess rail over-hang exists on the “fixed end”(the end not holding the indicator). Below you’ll find video instructions […]
Typically, if an internal threaded part is cut too large (too much material removed during threading), it ends up being rejected or scrapped. Because API RSC threads are tapered, moving the shoulder back makes the “over-sized” thread essentially “smaller.” When cutting/inspecting an internal API box rotary shouldered connection, it is not necessary to scrap the […]
