Special Feature: 1. Axis spacing display (drill spacing):NC system comes with digital display, spacing out of tolerance alarm, the system automatically calculates the drill spacing, real-time digital display of headstock displacement, with position out of tolerance alarm, completely eliminating human error One-key calibration: Z228i's unique calibration mode, one-key rotation, smooth acceleration, reduce the impact of the turntable, and extend the life of the turntable Hole surface spiral suppression technology (SHST): The unique surface spiral suppression technology (SHST) of the Mltor gun drill system can effectively eliminate the spiral line phenomenon in the hole and improve the quality Processing remaining time: automatic calculation and real-time update according to the feed rate Drill bit spacing and remaining row calculation: one-key realization, automatic calculation,no need for operator to calculate Back to designated row and hole function: input designated row and designated hole, automatic return, one-key realization 7. Even-numbered hole verification: to prevent artificial input hole number errors | |||
