WALTER UHL TECHNISCHE MIKROSKOPIE GMBH & CO. KG

Single or multiple specimen can be scanned in special holders (accessory) with low magnification. Various indentation patterns can be graphically defined within the stiched image after the scan by mouse. The testing results can be shown as color chart in the graphic.

specimen stage with analog micrometer spindles (25 x 25 mm) hand driven focussing axis electronic measuring eyepiece

Model similar to VMH-002 with high resolution digital video camera instead of the measuring eyepiece. the video image is shown directly on the integrated colour display comfortable and fatigue-proof measurement of the indentation on the video screen.

Model similar to VMH-002V with digital micrometer spindles direct creation of hardness depth patterns by graphical display and video image visual checkup of the minimum distance between edge and indentations according to the DIN EN ISO 6507/1-2 standard optional automatic indentation measurement (VMH-002VAD)

Model similar to VMH-002VD but with motorized specimen stage 50 x 50 mm and stepper motion controller with joystick automatic positioning of the specimen during hardness depth measurement the operator can prepare further specimen while the indentations are done automatically optional automatic indentation measurement (VMH-002VAM)

Hand driven video microhardness tester with image processing specimen stage with analog or digital micrometer spindles (25 x 25 mm) automatic indentation measurement (avoids user influence) flexible definition of hardness depth patterns with lists of steps or X/Y patterns

Motorized video microhardness tester with image processing motorized specimen stage 50 x 50 mm or 150 x 100 mm stroke

We provide a wide range of precise high valuable accuracy classified linear stages, open or closed frame XY stages, micropositioning elements and rotary or lift tables. Closed loop operation is supported by using optional steel or glas linear scales or rotary encoders. Standard stands in grey iron cast or granite are available additionally. The positioning systems can be driven by high resolution 1-, 2- or 3-axis motion controllers with joystick and RS232/USB/LAN interface.

The linear stages of the LT series are especially designed to provide high accuracy in compact dimensions. The bellows are protecting the bearings, spindles and scales from external influences. normalized aluminium alloy, black anodized anti-backlash pre-loaded cross roller guides or profiled rail guides anti-backlash pre-loaded ball screw

The fields of application for our linear stages LT and PT are widely spread. They are used where highest requirements on straightness deviations, noise behaviour or positioning accuracy are demanded. Stepping motors and backlash-free recirculating ball spindles are used as standard drive. Due to the usage of selective cross roller guides, highest accuracys are achieved which are recorded in the final check. For the adaption and mounting of the linear stages, several threads in grid layout are provided so that they can be combined to multi-axis positioning systems.
