Renishaw Ballbar Test

Renishaw Ballbar Test

At CNC Repair (UK) Ltd we use the market leading Renishaw ballbar QC20-W system. We can carry out ballbar testing, and analysis of the results on all types of CNC machine tools. We offer an onsite fixed price test & analysis at £475 per machine. Call us today on 0800 043 1800 to book your ballbar test. (Mileage charge does apply).

Ballbar testing provides a simple, rapid check of a CNC machine tool's positioning performance to recognised international standards (e.g. ISO, ANSI/ASME etc) allowing users to benchmark and track the performance of their machines and to quickly diagnose problems that may require maintenance and the error sources that produce them. 

Through ballbar testing we can help you:

• Accurately verify a machine’s performance.

• Achieve tight manufacturing tolerances.

• Verify a new machine’s accuracy at commissioning.

• Check machines after a "crash or collision" to ensure machine is able to achieve manufacturing tolerances, or to identify possible causes of machining errors.

How does ballbar testing work?

The Renishaw QC20-W ballbar is a precision measuring instrument (capable of measuring to + or - 1um of accuracy). It collects data on axis movements when moving in a circular motion. Any deviation from a perfect circle is measured. From the collected data problems with the machine's geometry such as squareness and straightness can be determined. Also dynamic errors such as ballscrew problems, backlash, reversal spikes, servo mismatch, stick slip can also be determined.

In addition to providing a ballbar testing service and reports to I.S.O standards, (with analysis of results), we also offer a comprehensive corrective action service to bring your machine tool back to the standard you require. This can include ballscrew repair / replacement, slideway repair / regrind & backlash elimination.
