Hommel Etamic Roundscan combines form, roughness and twist measurement
1 min read
An innovative Hommel Etamic Roundscan range, available in the UK and Ireland from Metrology Direct, meets the demand for a combined form, roughness and twist measurement system. The sub-micron measurements taken using Roundscan provide information on the quality of the part and the overall quality of the production process.
Roundscan is designed for fast and accurate measurement of a diverse range of parts from small intricate ones through to components weighing up to 100 kg. Highly precise measurement of form and roughness requires high resolution and maximum accuracy in all axes. Roundscan's rotary measuring table is on an air bearing, running on a wear-free cushion of air, providing a high roundness accuracy of 20 nm.
Key to the versatility of Roundscan is its FT3 probing system that can measure form, roughness and twist – of growing importance for parts such as gear shafts – without changing the measurement stylus. There are two different stylus tips: ruby ball for form and diamond tip for roughness measurement. The probing system can be switched from form to roughness under CNC control without changing stylus tips. Since the form and roughness measurement runs are combined, no operator intervention is necessary. The CNC controlled rotation and tilt module for the probe can position the stylus tips anywhere on the workpiece, including inside and outside, so that all measurement positions can be probed automatically in one measurement run.
With three fully CNC controlled measuring axes, Roundscan can undertake the measurement of all common form and roughness parameters automatically. The probe also features an indispensable collision protection feature.
Roundscan's standard Turbo Form software interface means the operator can carry out the most complex measuring tasks using user-friendly interface icons and simple CNC programming through pictograms. Turbo Form gives simple definitions of measurement positions, axis references and fully automatic alignment of parts to prevent angular errors. Users can incorporate their own drawings or photographs for reference.
Three Roundscan models in the range have vertical X-axes of 350, 550 or 900 mm and maximum test diameters of 450 and 550 mm depending on model. Measuring and traverse speeds range from 0.2 to 50 mm/sec and are controlled in the CNC program.
