Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Citizen Machinery. Configuration moves it a long way.
Overview
The Citizen Miyano ABX-51SYY appears to be an earlier twin-spindle Miyano with two tool slides and a Y axis on each side, listed with a 51 mm (2.0 in) bar capacity, 6,000 RPM on both spindles and 8 controlled axes (X1, Z1, Y1, C1, X2, Z2, Y2, C2). It is not in Citizen's current lineup and Citizen's current pages do not cover it, so treat the listed figures as a guide and confirm them on the machine.
On the listed figures, the main spindle is rated 7.5 / 11 kW (10 / 14.8 HP) with a 57 mm (2.24 in) bore, and the sub-spindle 3.7 / 5.5 kW (5 / 7.4 HP). Turning diameter is given as 65 mm (2.56 in) and turning length as 200 mm (7.87 in). Each side has ±30 mm (±1.18 in) of Y stroke, the turret is listed with 12 stations for VDI 30 or BOT tooling, and driven tools run to 6,000 RPM. Rapids are 30 m/min on X and Z and 20 m/min on Y.
Some listed figures sit oddly against the later ABX models: the Miyano ABX-64SYY2 is listed at 10,900 kg (24,030 lb), while this machine is given as 3,200 kg (7,055 lbs), with a Mitsubishi M80 control and a 1,950 x 1,750 x 1,750 mm (76.8 x 68.9 x 68.9 in) envelope. A buyer should weigh and measure, read the control nameplate and check the tooling interface before planning foundations or ordering holders.

Strengths & Limitations
Strengths
- Listed with 8 controlled axes, including Y and C on both the main and sub-spindle sides
- Both spindles listed at 6,000 RPM, with driven tools also at 6,000 RPM
- ±30 mm (±1.18 in) of Y stroke for off-centre milling and drilling on either spindle
- 51 mm (2.0 in) bar capacity through a listed 57 mm (2.24 in) spindle bore
Limitations
- Not covered by Citizen's current pages, so every listed figure needs checking on the machine before purchase
- Sub-spindle is listed at 3.7 / 5.5 kW (5 / 7.4 HP), so heavy back-side cuts are limited
- Turning diameter is listed as only 65 mm (2.56 in)

Frequently Asked Questions
01
No. It is not in Citizen's current lineup and Citizen's current pages do not cover it. Use the listed figures as a guide and confirm bar capacity, weight and control on the machine itself.
02
Eight are listed: X1, Z1, Y1 and C1 on the main side and X2, Z2, Y2 and C2 on the sub side. Each Y axis has a listed stroke of ±30 mm (±1.18 in), so both spindles can take off-centre milled and drilled features.
03
The main spindle is listed at 7.5 / 11 kW (10 / 14.8 HP) and 6,000 RPM, with a 57 mm (2.24 in) bore. The sub-spindle is listed at 3.7 / 5.5 kW (5 / 7.4 HP), also at 6,000 RPM.
04
The turret is listed with 12 stations for VDI 30 or BOT tooling, and driven tools run to 6,000 RPM. Those are different holder systems, so check which interface a particular machine has before buying holders.
