Overview

The Citizen Miyano BNE-65ATC is a 65 mm class twin-spindle lathe that adds a B-axis tool spindle with an automatic tool changer to two turrets. Citizen describes it as packing two spindles, two turrets, an ATC unit and a B-axis tool spindle into a small footprint, with simultaneous 5-axis machining for multi-face and complex-shaped parts that still start as turned work. Both spindles run to 5,000 rpm.

The ATC and B axis are what set it apart from the Miyano BNE-65MYY, which has the same spindles but relies on two 12-station Y-axis turrets alone. Here the turrets are unequal: TR1 has 10 stations and up to 10 revolving tools, TR2 has 12 stations and up to 12. The tool spindle on the B axis takes milling and angled-hole work that a fixed turret position cannot reach, and the changer means it is not limited to one cutter per job.

SP1 has an 18.5/ 15 kW motor (30-min/continuous) and SP2 11/ 7.5 kW (15-min/continuous). SP1 accepts H-S26, DIN177E and Hainbuch65 collet chucks; SP2 takes the same families plus H-S22 and carries a 6” hollow power chuck. Standard machining diameter on both spindles is 65 mm, and the spindle end faces are 740.5 mm apart.

Revolving tools on both turrets run at 6,000 rpm on a 4.0 kW motor. Rapids are 20 m/min on X1, Z1, X3 and Z3, 18 m/min on X2 and Z2, and 12 m/min on Y1 and Y2. The machine stands 2,177 mm high, weighs 9,200 kg and needs a 46.9 kVA supply, so check the shop's electrical capacity before delivery.

Strengths & Limitations

Strengths

B-axis tool spindle with an automatic tool changer alongside two turrets, for simultaneous 5-axis work
65 mm standard machining diameter on both spindles, each running to 5,000 rpm
SP1 motor rated 18.5/ 15 kW (30-min/continuous)
Revolving tools at 6,000 rpm on a 4.0 kW motor on both turrets
SP2 takes a 6” hollow power chuck as well as H-S26, H-S22, DIN177E and Hainbuch65 collets

Limitations

Weighs 9,200 kg against 8,130 kg for the Miyano BNE-65MYY, so foundation and rigging need planning
Needs a 46.9 kVA power supply
TR1 has only 10 stations and up to 10 revolving tools, against 12 on TR2
SP2 motor is 11/ 7.5 kW (15-min/continuous), well below SP1

Best For

Turned parts with milled faces and angled holes finished in one setup Complex-shaped parts needing simultaneous 5-axis work Bar and chucked work up to 65 mm diameter Jobs needing more milling tools than turret stations allow

Frequently Asked Questions

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

The BNE-65ATC adds a B-axis tool spindle with an ATC unit, and its turrets are 10-station (TR1) and 12-station (TR2). The Miyano BNE-65MYY has two 12-station turrets with Y axes and no B axis. Spindle speeds and motors are the same, and at 9,200 kg the BNE-65ATC is heavier than the 8,130 kg Miyano BNE-65MYY.

02 What spindle power does the BNE-65ATC have?

SP1 is rated 18.5/ 15 kW on its 30-min and continuous ratings, SP2 11/ 7.5 kW on its 15-min and continuous ratings. Both spindles run to 5,000 rpm. Revolving tools have their own 4.0 kW motor and run at 6,000 rpm.

03 Which collet and chuck types are listed?

SP1: H-S26, DIN177E and Hainbuch65 collet chucks. SP2: H-S26, H-S22, DIN177E and Hainbuch65 collet chucks, plus a 6” hollow power chuck. Standard machining diameter is 65 mm on both.

04 What are the rapid traverse rates?

X1, Z1, X3 and Z3 traverse at 20 m/min, X2 and Z2 at 18 m/min, and Y1 and Y2 at 12 m/min. The slower X2 and Z2 rates are worth allowing for when balancing work between the two turrets.

05 What does the BNE-65ATC need on site?

A 46.9 kVA power supply, floor capacity for 9,200 kg and headroom for a machine 2,177 mm high. The spindle end faces are 740.5 mm apart, which sets the space available for transfer between spindles.
