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 A20 is a 7-axis sliding-headstock lathe, the C-axis included, for 20 mm bar, with a 25 mm version listed as an option. It carries 21 tools, 4 of them live, and its main spindle runs to Max. 10,000 rpm. The A20 is not in Citizen's current lineup; the Cincom A20-VII is listed with the same max. 10,000 rpm spindle and 2,200 kg weight.

The 25 mm option changes more than bar size. At 20 mm the machine makes 200 mm per chucking through a TD25NS guide bushing; the 25 mm version uses a CD25 guide bushing and drops to 188 mm per chucking. Parts longer than one chucking stroke are made by re-chucking, so the per-chucking figure is the one to check against a drawing.

The main spindle has a 2.2 / 3.7 kW motor and a 26 mm (1.02 in) bore. The back spindle runs to Max. 8,000 rpm on 1.1 / 1.5 kW. Live tools are listed at Max. 6,000 rpm (Rating 4,500 rpm) on a 0.75 kW drive, which means cross holes, small flats and light slotting rather than real milling. With only 4 live positions, a part with many milled features will run out of driven tools before it runs out of stations.

Rapid traverse is 32 m/min, the control is listed as Citizen CNC and power consumption is 7.1 kVA. Centre height is 1,050 mm (41.3 in), which a bar feeder must match, and the machine weighs 4,851 lb (2,200 kg). For comparison the Cincom L20-XII ATC is listed with 46 (w/ ATC) tools, live tools to Max. 9,000 rpm and 2,680 kg (5,908 lb).

Strengths & Limitations

Strengths

20 mm bar capacity, with a 25 mm version (CD25 guide bushing) listed as an option
200 mm machining length per chucking at 20 mm
21 tool positions including 4 live tools, plus a back spindle to Max. 8,000 rpm
32 m/min rapid traverse and a 7.1 kVA power consumption
Main spindle to Max. 10,000 rpm on a 2.2 / 3.7 kW motor

Limitations

Live tools run at Max. 6,000 rpm (Rating 4,500 rpm) on 0.75 kW, so milling is light
Only 4 of the 21 positions are live tools
Back spindle motor is 1.1 / 1.5 kW, which limits back-end cuts
The 25 mm version drops machining length to 188 mm per chucking
Not in Citizen's current lineup; inspect any used machine
