The L.S. Starrett Co.’s HDV250 digital comparator is engineered to provide improved surface illumination, clearer image quality and enhanced measurement accuracy for manufacturing environments. The HDV250 is said to modernize the optical comparator workflow by replacing the traditional projection screen with a high-resolution camera and digital monitor while maintaining precise, crosshair-based measurement methodology. The result is sharper visualization, more reliable surface feature identification and improved inspection consistency.

At the core of the HDV250 is an integrated LED ring light-based surface illumination designed to provide enhanced surface contrast and clearer edge definition across a wide range of part finishes, especially for features that cannot be backlit. The advanced lighting system improves image clarity, enabling operators to inspect with greater confidence and micron-level precision.

Hainbuch ID Clamping Mandrel Boosts Machining Stability

Source: Hainbuch

Hainbuch’s Maxxos family of mandrels features the Maxxos T-212, an ID clamping solution engineered around the concept that geometry creates rigidity. The Maxxos design features a hexagonal pyramid clamping interface that replaces the traditional round mandrel connection between the mandrel body and the segmented clamping bushing. Instead of relying on friction alone, the hexagonal geometry creates a positive mechanical fit that increases torque transmission and resistance to vibration.

The result is a mandrel that holds parts with stability, even during aggressive machining operations. This added stability enables shops to increase feed rates, take heavier cuts and maintain consistent part quality while extending tool life.
