Overview
The Citizen Miyano BNA-42CY5 is a single-spindle, fixed-headstock CNC lathe with a 12-station Y-axis turret and a hydraulic tailstock, for work up to 42 mm (1.65 in) in maximum machining diameter. The spindle runs 60 - 6,000 RPM, and the controlled axes are X1, Z1, Y1, C1 and E1. The model is not in Citizen's current lineup.
Where the twin-spindle Miyano BNA-42SY5 has a sub-spindle for the back face, this machine has a tailstock instead, which makes it the choice for slender parts rather than parts that need both ends finished. The tailstock travels 200 mm with an MT2 taper and is driven hydraulically, with slide thrust adjustable from 0.57 kN (at 0.45 MPa) to 4.3 kN (at 3.4 MPa). Maximum machining length is 200 mm, with 300 mm given in brackets as the alternative.
All 12 turret stations can take rotary tools, driven by independent clutch at 50 to 5,000 min⁻¹ from a 2.8 / 1.0 kW motor; tapping is listed to M6 × 1. The Y axis has 70 mm of travel (+/-35 mm), X has 140 mm, and rapids are 20 m/min on X and Z and 12 m/min on Y. Tools are 20 mm square and tool post holes 25 mm in diameter. The spindle motor is listed as 11.7/5.5/5.5 kW (15.7/7.4/7.4 hp) without the rating names, so ask which duty each figure refers to.
The services are modest: AC 200 / 220 supply, 16 kVA, a 75 A fuse and 0.5 MPa of air. Tanks hold 225 L of coolant, 18 L of hydraulic oil and 2 L of lubricant, and the high-pressure coolant motor is 1.1 / 0.75 kW (60 / 50 Hz). The machine needs W 2,260 × D 1,433 mm of floor, is 1,745 mm high and weighs 3,430 kg, with a FANUC FS.0i-TF PLUS control.

Strengths & Limitations
Strengths
- 12-station turret with up to 12 rotary tools on independent clutch drive at 50 to 5,000 min⁻¹
- Y axis with 70 mm of travel (+/-35 mm) for off-centre milling and drilling
- Hydraulic tailstock with 200 mm of travel, MT2 taper and thrust from 0.57 kN to 4.3 kN
- 60 - 6,000 RPM spindle for work up to 42 mm (1.65 in) diameter
- Modest services: 16 kVA, 75 A fuse and 0.5 MPa air
Limitations
- Single spindle: the back face of a part needs a second operation
- Rotary tool motor is 2.8 / 1.0 kW and tapping is listed only to M6 × 1
- Spindle motor ratings are listed as 11.7/5.5/5.5 kW without saying which duty each applies to
- Not in Citizen's current lineup, so a used machine should be checked against these figures

Frequently Asked Questions
01
The Miyano BNA-42SY5 has a sub-spindle with a 4-inch chuck for back-side work and weighs 3,650 kg (8,047 lb). The Miyano BNA-42CY5 has one spindle and a hydraulic tailstock instead, weighs 3,430 kg and runs a FANUC FS.0i-TF PLUS control.
02
200 mm of travel, an MT2 taper and hydraulic drive. Slide thrust is listed from 0.57 kN at 0.45 MPa up to 4.3 kN at 3.4 MPa, so the support force can be set low for slender parts and higher for heavier cuts.
03
Up to 12, one in each turret station, with independent clutch drive at 50 to 5,000 min⁻¹ from a 2.8 / 1.0 kW motor. With 70 mm of Y travel (+/-35 mm) they can work off the spindle centreline.
04
An AC 200 / 220 supply rated 16 kVA with a 75 A fuse on the facilities side, and 0.5 MPa of air. Tanks take 225 L of coolant, 18 L of hydraulic oil and 2 L of lubricant.
05
It needs W 2,260 × D 1,433 mm of floor, stands 1,745 mm high and weighs 3,430 kg. Allow working space around that for the operator, chip handling and coolant service.
