Rapid and automatic verification

Five-axis machining is changing the face of advanced manufacturing. We understand how critical monitoring and control of the accuracy of your machine is to deliver the 5-axis performance you need. So we set out to make it simple and fast enough that it could be integrated into normal production - to avoid scrap, rework and unnecessary test samples. The result was the Rotary Inspector.

The Rotary Inspector is designed to determine, and correct, critical performance parameters with the accuracy and speed you need to integrate into the production schedule. It provides a simple approach to ensuring the geometric and dynamic performance of the machine.

Based on standard ISO measurements, the Rotary Inspector delivers fully automated measurement in less than a minute to derive the total 5-axis machine tool accuracy. It also calculates the pivot line offsets and squareness errors. A standard quality report is produced, simplifying in-house quality management of machines as well as providing an auditable document of the machine status.

An optional Rotary Inspector Data Manager module provides an overview of the history and current status of all machines integrated into the Rotary Inspector quality procedure. Machines can be monitored at a group, cell or factory level. This provides instant feedback on the status of the installed 5-axis machine base – for improved scheduling, reduced errors and customer compliance.
