Renishaw's QC10 ballbar is a linear displacement sensor based tool that provides a simple, rapid check of a CNC machine tool's positioning performance to recognised internationals standards. 

It allows users to benchmark and track performance of their machines and to quickly diagnose problems that require maintenance.

• Renishaw has been the market leader for machine tool performance diagnostics for over 15 years
• Renishaw has thousands of customers worldwide, from small owner/operators to global "blue chip" companies
• The QC10 is quick and simple to use with powerful results
• It increases process efficiency and company competitiveness
• The purchase costs are often recouped in months, or even on its first job

What is a Ballbar?
The Renishaw QC10 ballbar system is a CNC machine tool diagnostic system. It consists of a calibrated sensor within a telescopic ball-ended bar, plus a unique mounting and centration system. It is not to be confused with the fixed length ballbars used for CMM calibration.

A QC10 ballbar test involves asking the machine to scribe a circular arc or circle. Small deviations in the radius of this movement are measured by a transducer in the ballbar and captured by the software.

From the data supplied (via a PC interface) the systems software automatically detects and diagnoses a range of machine geometry, and motion errors. Recognized in many international standards for machine tool performance testing, the system is widely used by machine tool end users and OEMs and is considered vital equipment by many calibration service companies.

What Can a Ballbar Do For You?
The QC10 ballbar tests the performance of your machine tool.  The test usually takes just a few minutes from start through to analysis and gives you a selection of reports, which highlight any problems and their probable sources, putting you in control.

Whatever your role in your company there's a reason you should be using the QC10 ballbar

• Production - make decisions regarding production and maintenance with confidence, keeping you in control of your manufacturing process. You don't have to accept excessive scrap, or machine downtime, or wait for third party service companies. you may even reduce the need for work piece inspection, saving even more time and money.
• Quality - as part of your QA system, QC10 test records give accepted proof of performance (to International Standards such as ASME B5.54, ASME B5.57, JIS B6194 and ISO 230-4) satisfying audit requirements and a powerful tool when bidding for contracts.
• Maintenance - use regular testing to plan maintenance and to control the quality of repairs and servicing.
• Service - target your service time effectively by avoiding unnecessary investigaigons or even avoid engineer call outs altogether. Give your customers confidence in your service by sharing QC10 resultswith them, to show the effect of work carried out.
