The Lasercheck™ model A surface roughness sensor can be fully automated for high volumes and is capable of 10 surface roughness measurements per second. Examples include through-feed “centreless” grinding machines where 100% part surface roughness measurement is required. Taking inputs from proximity sensors, optical sensors or switches, a reading can be saved every time a part passes the measuring head. Relayed and analogue outputs are included which can trigger alarms or open waste gates when surface roughness is out of tolerance. The Model A can be used as a standalone unit or automatically log data, including batch number, date and time to a PC for QA/QC purposes. Push button manual mode is also included if required for one-off or batch work. This model can be used with the 6212 or 8826 measuring heads offering surface roughness measurements in the range of 0.0125 to 2.0 mm or 0.025 to 2.0 mm respectively.

Combining a Lasercheck on grinding machines with an SBS grinding wheel balancer means considerable surface finish improvement and 100% automatic Ra inspection is achievable.
