Spindle probes for CNC machine tools can be highly repeatable, but their performance relies on accurate calibration.

Gloucestershire-based engineering giant Renishaw has developed a simple solution to overcome the challenges associated with the manual probe calibration process while consistently achieving high levels of repeatability.

Accurate calibration is said to ensure the probe's performance is repeatable within the machine tool environment.

Today, many users perform the probe calibration process manually, which can cause variability even among skilled operators. Inaccurate probe calibration can affect all subsequent measurements; Renishaw's ACS-1 addresses this via a lockable mechanism that removes the need to use precision gauge blocks or slip gauges.

The ACS-1 can determine the probe's overall length and stylus ball diameter within minutes, and does not require batteries.

Richard Cox, design group applications manager for Renishaw's Machine Tool Products division, said: "ACS-1 is highly accurate, it reduces manual operation, therefore reducing human error, ensuring quick, accurate measurements. It also sits alongside our fully automated solution, AutoClock, offered by our associate company, MSP."

Renishaw added that the ACS-1 is now available to order worldwide.
