BALL BAR TEST

Using the RENISHAW QC20-W Ball Bar, we offer the simplest and fastest way to assess the main geometrical and dynamic performances of your machine tool in compliance with ISO 230-4 or ANSI/ASME B5.54.

Backlash, reversal spikes, slop, straightness, squareness, roll, cyclic issues and scaling mismatches for each axis are diagnosed and machine accuracy is calculated.

This test will help you to:

Reduce machine down time and implement fact base predictive maintenance
Ensure accurate parts and reduce scrap
Inspection of a second hand machine

MACHINE CHARACTERIZATION

This is the determination of accuracy and repeatability of all moving axis in a machine tool. With a Renishaw XL-80 laser interferometer and XR20-W rotary axis calibrator, we measure straightness and squareness’s orthogonal components, roll, pitch, yaw and positioning errors for each axis. The measurement of these parametric errors, if properly documented, are repeatable and form the foundation for future machine evaluation and possible optimisation.

These measurements will help you to:

Know and understand your machine tool accuracy limits
Compare with OEM standards
Compare the machine after future events or interventions
Calculate volumetric performance

MACHINE CALIBRATION

With the machine characterization documented, we can optimise your machine tool to improve the accuracy and repeatability. By using ball bar, laser interferometer, electronics differential level and precision squares, we mechanically adjust the geometrical attitude of your machine, search and fix the lost motion and update the compensation file. The new characterization is then documented and the volumetric performance is recalculated and compared with previous conditions and OEM specifications.
