The R500 model has been designed to assess the geometry of bulky or heavy workpieces whilst maintaining a high level of precision and reliability. The table has a 250 mm diameter and can bear weights of up to 60 Kg, even when they are out-of-balance. The metrological column can measure up to 500 mm in height and evaluate the straightness error of the workpiece along the vertical axis. The departure from true straightness can be evaluated using the ISO waviness filters: 0.25 – 0.8 – 2.5 – 8 mm.
The cycle of measure guides the operator in the operations of table centering and leveling and subsequently in the acquisition of the profile. Besides the default cycles of measure it is also possible to make calculations on the previously acquired profiles; moreover it is possible to plan the cycle of acquisitions. This is very useful especially when you have to measure many similar workpieces, with the same parameters and you need to enhance the measuring speed.
The software allows you to choose the method of calculation to perform the measurement and to elaborate the results. For the Roundness: circumference of the minimum squares, circumference of minimum zone, minimum circumscribed circumference, maximum subscribed circumference. For the Flatness: plan of the minimum squares, plan of the minimum zone, minimum superior plan, maximum inferior plan.
The tool can measure discontinuous surfaces, in fact it is also possible to evaluate the circular geometries even when the pick-up loses the contact with the surface; it is also possible to measure inside of caves thanks to the partial rotations of the table.
A large variety of accessories completes the SM Roundness testers equipment.
