2 A20 | Citizen
The Citizen A20, a 5-Axis CNC sliding head machine, with excellent cost / performance ratio now also featuring the ability to switch between guide bush and non-guide bush types
The A20 has further evolved as a 5-axis machine for φ20 mm applications with the advantage that it can now be used with or without a guide bush in a simple, easy to use procedure.
In standard guide bush mode it can machine both short parts and also long slender workpieces, and without a guide bush for shorter parts (maximum 3 x material diameter) with reduced bar end remnants.
Machine performance has also been improved with the main spindle now capable of up to 10,000 rpm enhancing machining operations on smaller diameter bar material and the machining length per single chucking has been extended to 200 mm. C axis is also available on both spindles.
The through bore of the main spindle has also been increased to 26 mm allowing the option of using bar material of up to 25 mm with optional oversize kit.

Machine performance & usability upgraded
The A20 machine now features the capability to switch between guide bush and non guide bush.
Spindle speed and main spindle chucking length have both been increased with good chip clearance and Citizens’ renowned ease of use and user friendly features.
Maximum spindle speed of 10,000 rpm.
Main spindle speed has been increased to 10,000 rpm enabling enhanced efficiency when using small diameter material.
200 mm/1 chucking
A longer 200 mm machining stroke reduces the need for re-chucking work-pieces hence reducing cycle time.
Support for stock material up to φ25 mm (option)
The spindle through bore is now 26mm enabling the use of up to 25mm / 1” material by installing the optional oversize kit.
A20 | Citizen 5
Machine performance & usability upgraded More speed, more stroke, more capacity = improved productivity
LED work lightAn energy efficient LED worklight is provided as standard giving a well illuminated working environment.
NC program transferNC programs can be input and output via. USB memory stick, CompactFlash card or RS232 connection.
Coolant nozzleCoolant nozzles are provided at the appropriate locations to ensure that sufficient coolant can be supplied to the point of machining.
Parts collectionThe large capacity collection box reduces the frequency of emptying.An optional workpiece conveyor is also available.
Chip collectionThe large capacity tank reduces the frequency of emptying.An optional chip conveyor is also available.
Adjustable operation panelThe pivoting operation panel enables easy operation whilst simultaneously viewing the machining process.

On-machine program check functionThe program can be ran round using the handwheel giving enhanced user confidence. The program can run in forward or reverse directions and can paused to edit before restarting.
Direct C-axis indexing functionDirect C-axis indexing enables deceleration direct to chosen index position eliminating the wasted time of performing zero return.
Display of code listThe function displays the list of G, M, and T codes including explanations - useful aid to programming.
Axis feed overlap functionThe next axis feed motion starts without waiting for completion of the current motion of another axis. This cuts out wasteful idle time and also suppresses unwanted vibration.
Easy viewing with text size changeTwo text size settings can be applied to each screen (large text display illustrated).
Productivity improvements
Screen display is easy to view and read
Idle time is slashed using the pre-processing function in the ‘Cincom Control’ that analyses the machining program before it is run to minimise processing and calculation times.
