Coordinate Measuring Machines (CMMs):

The Leitz CMM allows for automatic measurements of multiple part samples. An analog probe allows for continuous scanning in all three axes simultaneously. Its QUINDOS software provides geometric tolerancing calculations, along with gear and spline measurement capabilities. The Leitz CMM Model 12.10.6 is of laboratory grade with accuracies up to 0.00008 in. (0.002 mm). This equipment has a measurement volume of 47 in. x 39 in. x 24 in., a maximum weight capacity of 3,000 lbs., and is installed in DTB’s temperature-controlled dimensional lab on an 8 ft. x 6 ft. x 4 ft. concrete slab, which is designed to minimize externally-induced vibrations.

The Mitutoyo CMM Model Crysta-Apex C7106 is a direct computer-controlled high speed programmable CMM with a measuring range of 27 in. x 39 in. x 23 in. and accuracies up to ±0.0002 in. (±0.0051 mm). Capabilities include 2D and 3D measurement analysis; GD&T evaluations; and form, contour, and inspection to CAD models. The Mitutoyo CMM is fitted with a motorized Renishaw touch-trigger probe.

DTB also has a FaroArm Edge Model with 9 ft. measuring volume. We can measure using hard probing or laser scanning techniques on your parts. Volumetric accuracies are up to ±0.0016 in. (±0.041 mm) when using the hard probe.

Surface Roughness Measuring Station:

The dimensional lab contains a Mahr-Federal digitally filtered, non-skidded probe surface roughness measuring station. This station is capable of surface roughness analysis, per ASME B46.1.

Optical Comparator:

Our optical comparator is equipped with auto-edge detection and magnifications of 10x, 20x, and 50x. Capabilities include 2D measurement analysis and GD&T evaluations. The comparator can be run using either surface or profile illumination.
