Automated Milling Solution for Fast and Reliable Ferrous Metals Sample Preparation

Thermo Fisher Scientific, Inc announced the launch of an innovative solution for the preparation of ferrous metals samples for optical emission and X-ray fluorescence. The solution integrates the Haas Mini Mill milling machine from Haas, Inc with the Thermo Scientific ARL PrepControl automation extension.

The Haas Mini Mill with ARL PrepControl produces the high quality and reproducible prepared sample surfaces required for spectrometer analysis. With samples and standards introduced manually via the front door, it facilitates a semi-automatic operation. Additionally, the system can be easily integrated with automated Thermo Scientific ARL metals analysers and XRF spectrometers without the need for any modifications for entirely unattended, reliable and fast sample preparation and analysis.

The Haas Mini Mill with ARL PrepControl complies with the most stringent international safety and design standards. It yields unparalleled robustness and damping to resist vibrations and maximise cutting tips lifetime at high speed while reducing sample preparation time. The system is a true 3-axes milling machine designed for mass production of precision pieces and long life in a 24/7 non-stop operation. With speeds of up to 6,000 rpm, the direct drive spindle of the system provides optimal torque at low-end speeds for milling iron and steel. In addition, the rapid traverse rates of Haas brushless motors (up to 15.2 m/min) enable users to reduce response times and increase throughput.

The Thermo Scientific ARL PrepControl is a complete Haas Mini Mill automation extension, comprising a Siemens S7 programmable logic controller (PLC) with a movable colour touch screen as user interface and the ARL EasyPrep™ software for setting up and modifying preparation programs quickly and without the need for CNC programming. The solution also incorporates a sample clamping vice fixed on the Haas Mini Mill XY table and a sample surface positioning system using a fast sample height measurement device. Fully automatic operation is achieved under the control of the Thermo Scientific ARL SMS-2500/3500 automation system using state-of-the-art industrial robots for sample handling and providing for direct sample loading and unloading via a separate side door.
