Milling and drilling off the spindle centreline. The Y axis travels 70 mm (+/-35 mm) at 12 m/min (472 ipm), and all 12 turret stations can carry rotary tools at up to 5,000 rpm, so flats, slots and off-centre holes are done in the same cycle.
The Miyano BNA-42S has one turret without Y, 135 mm (5.31 in) of X travel and weighs 6,173 lb (2,800 kg). The Miyano BNA-42SY5 adds a 12-station Y-axis turret and 140 mm (5.51 in) of X travel, and weighs 3,650 kg (8,047 lb).
42 mm (1.65 in) on the main spindle. The sub-spindle takes 34 mm (1.34 in) as standard and 42 mm as an option, so check which is fitted if the back-side grip is on the full bar diameter.
The main spindle runs to 6,000 rpm with 11 kW and a 5 inch power chuck. The sub-spindle runs 50 - 5,000 rpm with 5.5 kW and a 4 inch chuck.
A footprint of 2,350 × 1,433 mm (92.5 × 56.4 in) for a machine of 3,650 kg (8,047 lb). The coolant tank holds 235 L, with 18 L of hydraulic oil and 2 L of lubricant.
