Renishaw QC20 Ballbar Machine Tool Performance Evaluation Kit in Original Foam Lined Box, Software Disk Bluetooth interface, and Zerodur Calibrator. Does not include VTL Adaptor.


QC20-W Ballbar System

Bluetooth wireless technology, totally revised electronics and enhanced test capability makes the QC20-W ballbar system even simpler to use and more powerful than its QC10 predecessor. 

At the same time, test processes and results are compatible for QC10 users.

Review latest software and software upgrades

The QC20-W system draws on Renishaw's many years of experience with ballbar testing and offers

 significant performance and operational benefits  

Bluetooth wireless technology ensures no wire handling issues, closed door operation and
     reduced possibility for system damage.
New hardware and software which allows a 'partial arc' (220°) test.
This gives you greater test flexibility including
improved Z axis testing (no custom fixturing required)
tests where axis travel is limited (typically Z axis on machining centres and X axis on lathes)
ability to test 3 planes from a single set up, using 'partial arc' tests for 2 of the tests and
present a 'volumetric analysis' 
Faster data reading for enhanced analysis on small test circle and high feed rates.
Enhanced software includes many new features for extended testing and greater ease of use. 

Diagnose and Quantify Machine Tool Positioning Errors 

The new design also allows testing in 3 orthogonal planes through a single reference point. A single, simple hardware set up means quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy. The QC20-W ballbar retains the principle of a simple CNC circular program, and powerful software. Together, these can quickly diagnose and quantify machine positioning errors including, servo mismatch, stick-slip errors, backlash, repeatability, scale mismatch and machine geometry as well as giving an overall circularity error value.


The Ballbar 20 system software has been enhanced to give even greater flexibility for testing and reporting. The QC20-W kit is supplied in a redesigned, robust system case, which includes spaces for the most popular accessories.

With many thousands of established users of the QC10 system, Renishaw has gone to great lengths to ensure backward compatibility with the QC10 system. This minimises costs and disruption when upgrading or working alongside existing QC10 systems.

Ballbar lengths are identical to QC10, so all existing test routines can be carried over including test templates, CNC programmes, and work and test procedures. Only minimal training is required when upgrading, focusing on familiarisation with the new features. The Ballbar 20software is also compatible with QC10 systems as the test file format is unchanged. As a result both old and new machine records can be reviewed using the same software. 

Using Optional Accessories

The QC20-W ballbar system can be enhanced by using  a range of accessories. 

With additional extensions it is possible to perform tests up to 1350 mm radius.
The small circle kit allows 50 mm radius tests to be carried out. 
Testing can also be carried out on two axis machines using the VTL adaptor and on many
lathes using the lathe accessory kit

With all these options, plus the flexibility to use various feedrates, the QC20-W allows very flexible testing.

Your Video Guide to Ballbar Testing

Getting started with QC20-W ballbar DVD 


Every QC20-W ballbar kit includes the 'Getting Started with QC20-W ballbar' DVD which

introduces the system, takes you step-by-step through the equipment, set-up, installation

and use of the system, and shows you how to carry out a test and review the results.

Kit Contents

QC20-W wireless ballbar kit


The standard QC20-W kit comes in its own robust carry case which includes the

QC20-W wireless ballbar, battery, spindle and table mounts (pivots), 50 mm, 150 mm

and 300 mm ballbar extensions (to allow various test diameters) and tools.

 Ballbar 20 software and manual are supplied on a single CD with a

'Getting started' video guide provided on a separate DVD. Also included is a calibrator

for enhanced test analysis. (It enables absolute readings for scale errors and a

handy means of checking that the ballbar is reading nominally correctly).

Fully traceable calibration certificates, for the ballbar and calibrator and

validation labels to display test results on machines are also included in the kit.

All kit items can be ordered separately as spare parts.
