Product Description
RENISHAW BLUETOOTH BALLBAR QC20-W
Besides the rental service,we also provide on-site Ball Bar check on your machine. The Ball Bar test is able to diagnose the machine inaccuracy at the same time ,check squareness, reversal spikes, cyclic error, scaling factor, servo mismatch and more.
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.
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.
