Overview

The Citizen Cincom L20 on this page is an earlier 20 mm (0.787 in) sliding-headstock lathe, listed without a generation number. It is not in Citizen's current lineup, and its table has not been checked against a manufacturer source, so the figures below are the listed figures for the model and a used machine should be confirmed against its own plate and manual.

The listed figures describe a compact two-spindle machine. The main spindle runs to 10,000 RPM with a 3.7 kW (5 HP) motor, and the back spindle to 8,000 RPM with full contouring on the back side. Rotary tools run to 5,000 RPM. The axis count is given as 5, rising to 7 with the C1 and C2 axes, which on a used machine is the first thing to check: the C axes are what allow milled flats and off-centre holes in the cycle.

The guide bushing is standard and a non-guide-bushing option is listed. The approximate footprint is 1800 x 1200 mm, small enough for a tight cell, and the control is Mitsubishi Meldas with Citizen software. Rows for machining length, gang tool positions and LFV vibration cutting disagree with each other in the table, so those are left for the buyer to confirm on the machine.

Strengths & Limitations

Strengths

Takes bar up to 20 mm (0.787 in) through a sliding headstock with guide bushing
Main spindle to 10,000 RPM on a 3.7 kW (5 HP) motor
Back spindle to 8,000 RPM with full contouring on the back side
Approximate footprint of 1800 x 1200 mm

Limitations

Earlier model with an unchecked table; machining length, tool positions and LFV rows conflict
Rotary tools listed at only 5,000 RPM
5 axes as listed; the 7-axis count needs the C1 and C2 axes fitted
Not in Citizen's current lineup

Best For

Turned parts from bar up to 20 mm (0.787 in) Simple turned-and-drilled parts with back-side work Buyers of used 20 mm Swiss-type lathes able to inspect the machine

Frequently Asked Questions

01 Is the Cincom L20 still in production?

Not under this name. The plain L20 is not in Citizen's current lineup, and the table on this page has not been checked against a manufacturer source. Identify the generation from the model plate of a used machine before comparing it with a current spec sheet.

02 How many axes does the Cincom L20 have?

The listed figure is 5 axes, up to 7 with the C1 and C2 axes. The C axes index or position the main and back spindles for milling and cross drilling, so a used machine without them is limited to turning and on-centre work.

03 Can the Cincom L20 run without a guide bushing?

The listed figures give the guide bushing as standard and a non-guide-bushing option. The option suits short parts and reduces the bar remnant; the guide bushing supports long slender work. Check which one a used machine was built with and whether the other configuration's parts come with it.

04 What spindle speeds does the L20 offer?

The listed figures are 10,000 RPM for the main spindle on a 3.7 kW (5 HP) motor, 8,000 RPM for the back spindle and 5,000 RPM for the rotary tools. The rotary tool speed is low for small drills, which is worth weighing for parts with many fine cross holes.
