QC20-W telescoping ballbars from Renishaw Oceania incorporate Bluetooth wireless technology. They have had a significant impact on CNC machine testing around the world. A lot of customers believe that the new QC20-W ballbar offers significant advantages over Renishaw’s QC10 product.

One of the first customers for QC20-W was NC Service, a Swedish machine tool service and maintenance company, who work with CNC machine users. Peter Jönsson, Managing Director of NC Service, was full of praise for the product. “Since switching over to QC20-W ballbar the setup-time has been greatly reduced, speeding up our operations. We no longer have trouble with the cable anymore which ensures a safer operation as we can operate the test from outside the closed safety doors,” he said.

Jönsson remarked how much he was looking forward to using the ‘volumetric analysis’ function and he confirms that NC Service is now utilising this functionality in most of their testing. He also said that “Ballbar20 software is very easy-to-use and my operators found the transition to the new software very smooth due to its similarity with the QC10 software.”

A feature of QC20-W is the use of Bluetooth wireless technology which allows simplified and consistent ballbar testing in 3 orthogonal planes. A single, simple hardware set up gives quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy. In addition, Renishaw’s ballbar enables users to quickly diagnose and quantify machine positioning errors and give an overall 'circularity' error value as per ISO and other standards.

Both software and key hardware features ensure backward compatibility for the thousands of QC10 system users worldwide by providing stress free upgrades and minimising the costs of moving to the new system, or working alongside existing QC10 systems.
