R-test determines rotary axis location in multi-axis machine tools

The R-test system from Dutch measurement specialist IBS Precision Engineering offers a fast and precise method of determining rotary axis location, providing simple x, y and z co-ordinate readouts. The R-Test system provides data analysis to ISO 230 machine tool testing standard and achieves sub micron accuracy without the intricate and painstaking procedures of traditional machine alignment and set-up methods. It is suitable for calibrating swivelling head as well as both 360 degand limited arc rotary table CNC machines, with offset errors for rotating axes computed either independently or in combination. The portable R-test system consists of an MT-Check probe with interface unit, a stem-mounted precision 22 mm diameter carbide Masterball, toolholder with alignment unit and all necessary mounting tools.
