Ballbar test to ensure the roundness and geometrical precision.
Every machine is inspected carefully before shipment. International standard dynamic cutting specimen is also required to pass the inspection. The specimen is tested through CMM to ensure the result of the actual cutting standard.
Standard Specimen
Full travel dynamic precision through laser compensation calibration
