Renishaw's new CNC probe calibration machine

Renishaw has launched a new solution to improve the accuracy and repeatability of CNC machine tool probe calibration with the ACS-1. Conventionally, probe calibration is often done manually, which leaves room for human error.

The new ACS-1 probe circumvents this issue in a simple, but effective way: “ACS-1 is mounted on the machine tool table or chuck using its magnetic base. A test bar (or a tool of known length) establishes an accurate datum surface by pushing the plunger down to the desired position; the plunger is locked in place. The probe’s overall length can be accurately calibrated, using the calibration disk (the top surface of the lockable plunger). The probe's stylus ball diameter calibration takes place on the Datum sphere, which can be mounted in two different positions on ACS-1, according to the CNC machine configuration.”

Because the ACS-1’s Datum sphere can be mounted on two different 45-degree angled faces, it provides the adaptability that allows it to be used for a wide range of CNC machine tool configurations. With a magnetic base, the ACS-1 can be mounted both vertically or horizontally on vertical mills, lathes, turn-mills and 5-axis machines.

"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,” says Richard Cox, Design Group Applications Manager for Renishaw’s Machine Tool Products division.

Battery-free and operating within a scope of minutes, the ACS-1 is now available worldwide.
