The RA-10 Roundtest roundness measuring machine is said to combine comprehensive measurement capabilities, high accuracy and intuitive operation. With high throughput and a compact footprint, the machine is suited for manufacturers requiring inspection of small, cylindrical workpieces in the lab or for high-volume inspection on the production floor. It features a large touch-panel control and high-visibility LCD display to reduce the chance for error when inputting or reading out. Operation is intended to be simplified, with functions such as One-Stroke Recall (which stores measurement steps in advance for recalling via a single keystroke) and the Zero-Set function (which enables the detector’s level to be zeroed-out with one key press, eliminating the need for the operator to re-position the detector). Additional conveniences include an X-axis stopper and a Z-axis scale unit. Measurement data can printed from the built-in printer, output via RS232C or SPC ports or stored to external memory through a USB port.
The measuring machine has a maximum probing height of 5.98" (152 mm); a maximum probing depth of 3.94" (100 mm); a maximum vertical (Z-axis) travel of 4.61" (117 mm); and a maximum horizontal (X-axis) travel of 2.95" (75 mm), including a protrusion of 1" (25 mm) for turntable rotation center.
The machine uses setup jigs to simplify and speed workpiece positioning. According to the company, the need for centering and horizontal alignment when setting a workpiece can often be eliminated, thereby improving the efficiency of repetitive measurement. Equipped with an air bearing rotary table, the machine has a rotational accuracy of (0.04+6H/10000) microns. A variety of optional auxiliary tables is available.
