SISCO Concentricity Testers Supporting Quality Control

Machining accuracy depends not only on cutting tools and machine settings but also on the condition and alignment of workholding equipment. Incorrectly positioned fixtures, worn locating surfaces, or unsuitable supports can influence the geometry of machined components and introduce errors into production. SISCO concentricity testers help workshops investigate these issues by measuring deviations on suitable cylindrical test pieces, locating features, and tooling components. When a workpiece is mounted on an appropriate measuring arrangement, operators can observe changes in indicator readings during rotation and compare the results with established acceptance criteria. Such checks are useful when evaluating precision mandrels, cylindrical locating pins, fixture adapters, and other components that influence how a workpiece is positioned during machining. A stable reference and carefully controlled setup are essential because mounting errors can affect the results. By establishing consistent inspection procedures, technicians can distinguish possible workpiece defects from problems associated with tooling or workholding arrangements. SISCO concentricity testers offer a practical addition to workshop metrology equipment because they support direct mechanical measurements without requiring every inspection task to involve a complex electronic system.
