Overview

The Citizen Miyano BNE-65MYY is a 65 mm class fixed-headstock lathe with front and back spindles and two 12-station turrets, each with a Y axis. Both spindles run to 5,000 rpm, maximum machining length is 195 mm, and up to 24 rotary tools can be installed across the two turrets.

The layout is about balance. With twelve stations on each turret, tools do not have to be crowded onto one side, and Citizen points out that process allocation is not restricted by machining balance limitations. Because both turrets have Y, the front and back spindles can be worked at the same time, including left/right and up/down simultaneous machining, which is where the cycle-time saving on superimposed operations comes from.

Work-holding is broad. The listed collet chucks are Hardinge S22, DIN177E and HAINBUSH 51, and power chucks come as 6" 3-claw or 6" 2-claw. The two-jaw option suits forgings and irregular blanks that a three-jaw cannot centre. Turning tools are 20 mm Sq. and tool post holes 25 mm dia.

SP1 is rated 18.5/15 kW (30-min/continuous) and SP2 11/7.5 kW (15-min/continuous). Rotary tools run at 6,000 rpm on a 4.0 kW motor. Feed rates are 20 m/min on X1, Z1, X3 and Z3 and 18 m/min on X2 and Z2. Compared with the Miyano BNE-65ATC, which adds a B-axis tool spindle and tool changer, this machine is lighter at 8,130 kg against 9,200 kg and lower at 2,070 mm. It needs a 47 kVA supply and a floor area of W2,860×D2,190 mm.

Weighs 8,130 kg and occupies W2,860×D2,190 mm

Best For

Parts up to 65 mm diameter with milled features at both ends Simultaneous front and back machining to cut cycle time Forgings and irregular blanks in a 2-claw chuck Jobs with many tools split across two turrets

Frequently Asked Questions

01 Do both turrets on the BNE-65MYY have a Y axis?

Yes. Citizen states that the two turrets are equipped with a Y axis, and that with the front and back spindles this allows simultaneous left/right and up/down machining. Each turret has 12 stations, with up to 24 rotary tools in total.

02 How does the BNE-65MYY differ from the BNE-65ATC?

The Miyano BNE-65ATC adds a B-axis tool spindle with an ATC unit and has a 10-station and a 12-station turret; it weighs 9,200 kg. The BNE-65MYY has two 12-station Y-axis turrets, no B axis, and weighs 8,130 kg. Spindle motors and speeds are the same on both.

03 Which chucks and collets can be used?

Collet chucks listed are Hardinge S22, DIN177E and HAINBUSH 51. Power chucks listed are a 6" 3-claw chuck and a 6" 2-claw chuck. Standard machining diameter is 65 mm.

04 How much power does the BNE-65MYY need?

The power requirement is 47 kVA. SP1 has an 18.5/15 kW motor (30-min/continuous), SP2 an 11/7.5 kW motor (15-min/continuous), and the rotary tools a 4.0 kW motor.
