QC20-W ballbar and ballbar kit QC20-W ballbar The QC20-W ballbar contains a precision linear transducer of Renishaw’s own design (patent applied for). It is used to measure variations in radius as the ballbar is rotated around a fixed point. This data is used to calculate overall measures of contouring performance (circularity, circular deviation) of CNC machine tools, in accordance with international standards such as ISO 230-4, ASME B5.54/57 and GB17421.4. System software also provides a detailed diagnosis of contributing individual error sources when analysed using Renishaw’s unique...

apply innovation™ Testing capability The standard QC20-W ballbar kit includes a 100 mm long ballbar assembly and 50, 150 and 300 mm long extension bars. By assembling the ballbar with different combinations of extension bars it is possible to carry out ballbar tests with 100, extensions it is possible to perform tests up to 1350 mm. The optional small circle kit allows tests with a 50 mm radius and testing can also be carried out on two-axis machines and lathes using optional accessories (page 6). Redesigned ball mounts (including new centre pivot and tool cup extension) allow the QC20-W to...

apply innovation™ The software also allows you to: • Set individual warning and failure performance bands for each machine characteristic • Get instant notification, during the ballbar test, if a machine's performance exceeds these tolerances There's even a combined history plot which shows the independent circularity values for all parameters over time. This is a very useful "first stop" in reviewing the performance history of a machine and the relative importance of the errors Machine history allows you to: • Predict maintenance requirements in advance to reduce unscheduled downtime •...

System accessories Small circle accessory kit VTL adaptor The small circle accessory kit is used with the QC20-W ballbar to allow tests with a radius of 50 mm. This can be useful when testing machine axes with short axis travel, or to emphasise the effects of servo and dynamic errors on the machine (small circles require higher machine accelerations and decelerations). For 2-axis CNC applications the VTL adaptor is available (this replaces the “tool cup” in the standard set-up and restricts movement of the centre cup to a single axis only.) This enables typical 2-axis machines such as...

apply innovation™ The lathe adaptor kit allows you to perform 360°, 100 mm radius ballbar tests on a lathe. The kit consists of an arm assembly for attachment to the lathe turret and a spindle bar for attachment in the lathe spindle. Both arm and spindle include magnetic cups in which to locate the ballbar; the one in the arm is equivalent to the tool cup in the normal kit set-up and the one in the spindle bar is equivalent to the pivot Note that to use this kit your lathe must have the following On lathes with restricted axis travel it may be possible to perform a 50 mm radius test using...
