Product OverviewScroll chucks provide dead-true concentricity and offer 0.0005" repeatability on duplicate parts. This precision is achieved by a built-in 0.020" clearance between the chuck body cavity and the mounting plate hub, which allows opposing screws sufficient movement to align the work accurately. Adjustment takes less than one minute; once set, no further adjustment is required to maintain 0.0005" TIR on duplicate parts.Features & Benefits0.0005" repeatability on duplicate parts (some documentation also references 0.001")Cast iron body for a cost-effective manufacturing solutionHardened and ground scroll, dynamically balanced for improved accuracyHardened and ground jaws for extended service lifeApplicationsTool-room work and precision turningGrinding operationsTechnical SpecificationsRepeatability: 0.0005" (page also references 0.001")Clearance between chuck cavity and mounting plate hub: 0.020"Body material: Cast ironScroll: hardened and ground, balanced for higher accuracyJaws: hardened and ground for longer lifeAdjustment time to achieve precision: less than one minute
