Inspection System Verifies Cutting Tool Geometries
IMTS 2018: Johnson Gage’s JCR runout and concentricity inspection system enables verification of cylindrical runout.
Johnson Gage’s JCR runout and concentricity inspection system enables verification of cylindrical runout. The system can be used with an optical comparator or by itself for verification of geometries in cutting tool products. It incorporates precision datum rolls, an upper tension roll assembly and integral axial stop pins to assure proper part staging and gage accuracy.
The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.
Different instruments (and different operators) are prone to different errors.
While countersunk and chamfered holes are similar in appearance, functionally they are quite different. Consequently, different gages exist to serve these different functional requirements.
