Y-axis deviation
To measure the volumetric accuracy, a 1,000 mm master gauge (cylindrical measuring fixture) is placed vertically on the table and the deviations along the Y-axis (from 0 mm to 1,000 mm) are measured at 3 points on the X-axis (0 mm, ± 200 mm). DIXI machines achieve a positioning error within ±2.5 μm, even without using the NC unit's offset functions.
Machine precision on a test piece
(true position boring accuracy)
During machine accuracy measurement in which nine Φ 20 mm holes were bored with a 200 mm pitch from the 0º and 180º positions on the B-axis, we achieved machining error within ± 4 μm for all holes.
