Non-Cartesian CMM Integrates CNC Machining With Process Control

Aberlink has extended its EXTOL Coordinate Measuring Machine, the world’s first CMM to utilize a delta mechanism, with the addition of the larger measuring volume 520 model.

Designed for robustness and reliability, the Extol CMM will run around the clock making it ideal whether it is positioned next to a machine tool, in a manufacturing cell, or used in a dedicated inspection area.

Five temperature sensors monitoring both the machine and ambient temperature ensure that the Extol is capable of operating in uncontrolled environments and reporting measurements as though they had been taken at 20°C The software will also produce a warning should the temperature change at a rate that is not conducive with reasonable metrology practice.

The Automatic Tool Offset Correction, available with the Aberlink 3D software, compliments the attributes of the Extol perfectly allowing utilization as part of a fully automated production process in the midst of a manufacturing environment.

The ergonomics of the Extol have also been a significant design factor. It is not only quick and easy to perform one-off inspections, but also has ample access for either batch inspection or to facilitate automatic loading. The Extol 520’s large measuring volume of 520mm x 520mm x 300mm and small overall footprint allows the Extol to be positioned exactly where the measurement is needed.

Robust, accurate and reliable, the Extol CMM is the perfect solution to automatically verify part quality for critical components.

Measurement Outside The Box

The Extol delta design mechanism, delivers a cylindrical measuring volume rather that the traditional orthogonal box measuring volume. The EXTOL’s, compact footprint, performs with a measuring accuracy of 2.6 + 4L/1000 μm, incorporates 0.1 μm resolution scales, and has a more than ample granite table payload. Vertically mounted machine-tool linear guide-ways provide the measuring platform motion via thermally inert carbon fiber struts.

Delta mechanisms are renowned for their repeatable motion with high acceleration and speed. The Extol CMM delivers with maximum vector speeds of 500mm/sec and maximum vector accelerations of 750mm/sec².
