Locators Overview

• Locators are precision elements used to position components in jigs, fixtures, and special tooling so that each part is loaded in exactly the same reference position.​ ​
• Typical locator styles include pins, buttons, rest pads, and V‑blocks, which control key datums such as holes, edges, or diameters for consistent machining results.​​ ​
• Quality locators improve cycle time, reduce operator dependency, and help maintain tight geometric tolerances across large batches of parts.​​​

Mandrels Overview

• Mandrels are internal clamping devices designed to hold components by their bore, providing rigid and concentric support during turning, grinding, or inspection.​​
• Expanding mandrels use a tapered or segmented design to expand inside the part, distributing clamping forces evenly to minimize distortion, especially in thin‑walled or long components.​
• They are widely used for gears, rings, tubes, and precision sleeves, where accurate control of outer diameter and runout is essential.​​​​

Applications and Benefits

• CNC Turning and Grinding: Secure clamping of rings, hubs, and sleeves by internal diameter for superior concentricity and surface finish.​​​
• Inspection and Metrology: Mandrels and locators provide stable, repeatable referencing on CMMs and gauges for high‑accuracy measurements.​​
• Batch and High‑Volume Production: Engineered locator layouts and custom mandrels reduce changeover time, improve throughput, and maintain consistent quality across thousands of parts.​​​​
