The Citizen A20, an evolving 5-Axis CNCsliding head machine, furthers the questfor cost and performance featuring theability to switch between guide bushand non-guide bush types.Acclaimed for its excellent cost to performance ratio, the A20 has evolved as a 5-axis machine for 20 mm diameter applications withthe advantage that it can be used with or without a guide bush. It can be used as a regular guide bush automatic lathe whenmachining long slender workpieces, and without a guide bush for shorter parts with minimal bar end remnants. The guide bush can bequickly and simply mounted and removed.The performance of the machine has been improved too. The high speed 10,000 rpm spindle enables optimised machining operationson smaller diameter bar material. The machining length per chucking is now extended to 200 mm enabling the number of re-chuckingsand therefore cycle times to be reduced when machining long workpieces. As an option, bar material of up to 25 mm diameter canalso be machined extending the range of workpieces.02 Cincom A20

Along with machine performance, usabilitMore speed, more stroke, more capacity The A20 features a new capability to switch between guide bush and non-guide bush operating modes.The machine's performance, including spindle speed and machining length per chucking, has been increased.It is designed for ease of use and convenience with good chip clearance for fast set-ups.Maximum spindle speed of10,000 rpm.The maximum speed of the front spindle ishigh at 10,000 rpm enabling optimizedmachining conditions on small diameter barmaterial or using small diameter cutting tools.04 Cincom A20200 mm/ 1 chuckingA longer 200 mm machining stroke reducesthe need for re-chucking workpieces hencereducing cycle time.Support for stock materialup to 25 mm diameter (option)With its spindle through hole diameter of 26mm, the A20 is capable of machining bar stockup to 25 mm dia. by installing the optional 25mm size chuck device – enabling a wider rangeof workpieces to be produced over the standard20mm machine.

ty has also been upgraded. improved productivity.Work lightUSB/PC card slotLow energy illumination is provided as standardin the machining area giving an environmentthat is bright with ideal visibility.NC programs can be input and outputusing the USB slot or PC card slot on thefront face of the control panel.Coolant nozzleParts collectionCoolant nozzles are provided at the appropriatelocations to ensure that sufficient coolant canbe supplied to the point of machining.The large collection box reduces the frequency ofemptying. The optional workpiece conveyordischarges to the left front of the machine.Coolant tank/chip collection boxAdjustable operation panelA 150-litre coolant tank is standard,enabling extended periods of operation.The chip outlet port has been increased toimprove chip removal. Optional chipconveyors are available to suit the type ofchip material.The pivoting operation panel enables easyoperation whilst simultaneously viewing themachining process.Cincom A2005
