Our best estimate for a swiss-type lathe in this class — not a quote from Citizen Machinery. Configuration moves it a long way.
Overview
The Citizen Cincom D25 is a 25 mm sliding-headstock automatic lathe built around three tool groups: the gang tool post with rotary tools, the back spindle and a back tool post with its own rotary-tool drive. Citizen does not list a plain D25 in its current lineup; its D25 page carries two types, the Cincom D25-VII and the Cincom D25-VIII, and a machine sold simply as a D25 should be identified as one or the other before you compare figures.
The figures common to both types are on this page. Bar capacity is 25 mm, and the stroke is 250 mm with the guide bush or 2.5 times the diameter (listed as 2.5D) in guide-bushless mode. The main spindle runs to 10,000 rpm on a 3.7/5.5 kW motor and drills to 12 mm and taps M10 at the front. Gang rotary tools reach 9,000 rpm on a 2.2 kW drive, with 10 mm drilling and M8 tapping.
The back spindle is unusually capable for the class. It takes a 25 mm chuck, runs to 10,000 rpm on a 2.2/3.7 kW motor and handles 12 mm drilling and M10 tapping with 50 mm of work protruding, so the back end of a part gets nearly the same capacity as the front. Its rotary tools on the back tool post are driven by a 1.0 kW motor. The table also marks LFV chip breaking.
The two types differ in tool count. The table's own row gives 43, a summary row gives 35 to 59 depending on configuration, and Citizen lists 59 for the Cincom D25-VII and 43 for the Cincom D25-VIII. Plan for a 13 kVA supply (7.1 kVA average), 3,450 kg and a floor area of 2,440 x 1,380 mm (96 x 54.3 in) at 1,795 mm high.

Strengths & Limitations
Strengths
- Back spindle matches the front: 25 mm chuck, 10,000 rpm, 12 mm drilling and M10 tapping
- Gang rotary tools at up to 9,000 rpm on a 2.2 kW drive, with 10 mm drilling and M8 tapping
- 250 mm stroke with the guide bush, plus a guide-bushless mode listed at 2.5D
- Separate 1.0 kW drive for rotary tools on the back tool post
- LFV chip breaking is marked in the table
Limitations
- Citizen does not list a plain D25 today, so a used machine must be identified as a D25-VII or D25-VIII
- The table gives both 43 tools and a 35 to 59 range, so confirm the tool layout of a specific machine
- At 3,450 kg and 13 kVA it needs a heavier floor and supply than 12 mm and 16 mm machines
- Guide-bushless stroke is limited to 2.5 times the diameter

Frequently Asked Questions
01
Citizen's current D25 page lists two types, the Cincom D25-VII and the Cincom D25-VIII, rather than a single D25. They share the 25 mm bar capacity, 10,000 rpm spindles and 3,450 kg weight. Citizen gives 59 tools for the D25-VII and 43 for the D25-VIII.
02
The back spindle takes a 25 mm chuck, runs to 10,000 rpm on a 2.2/3.7 kW motor and allows 50 mm of protrusion. Back drilling is listed to 12 mm and back tapping to M10, the same as the main spindle's front drilling and tapping, and the back tool post has its own 1.0 kW rotary-tool drive.
03
Yes. The table gives a maximum machining length of 250 mm with the guide bush and 2.5D, two and a half times the diameter, in guide-bushless mode. Guide-bushless running suits short parts and reduces bar remnant.
04
The table lists a 13 kVA rated power consumption and 7.1 kVA average during load operation. The machine weighs 3,450 kg, occupies 2,440 x 1,380 mm (96 x 54.3 in) of floor and stands 1,795 mm (70.7 in) high, with a centre height of 1,050 mm.
