Acclaimed for its excellent cost to performance ratio, the A20 has evolved as a 5-axis machine for φ20 mm applications with the advantage that it can be used with or without a guide bush. It can be used as a regular guide bush automaticlathe when machining long slender workpieces, and without a guide bush for shorter parts with minimal bar end remnants. The guide bush can be quickly and simply mounted and removed.

The performance of the machine has been improved too. The high speed 10,000 rpm spindle enables optimised machining operations on smaller diameter bar material. The machining length per chucking is now extended to 200 mm enabling the number of re-chuckings and therefore cycle times to be reduced when machining long workpieces. As an option, bar material of up to φ25 mm can also be machined extending the range of workpieces.

Along with machine performance, usability has also been upgraded. More speed, more stroke, more capacity = improved productivity.

Cincom A20 05

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.

Work lightLow energy illumination is provided as standard in the machining area giving an environment that is bright with ideal visibility.

Maximum spindle speed of 10,000 rpm.The maximum speed of the front spindle is high at 10,000 rpm enabling optimized machining conditions on small diameter bar material or using small diameter cutting tools.

200 mm/1 chuckingA longer 200 mm machining stroke reduces the need for re-chucking workpieces hence reducing cycle time.

Support for stock material up to φ25 mm (option)

With its spindle through hole diameter of 26 mm, the A20 is capable of machining bar stock up to φ25 mm by installing the optional 25 mm size chuck device – enabling a wider range of workpieces to be produced over the standard 20mm machine.

USB/PC card slotNC programs can be input and output using the USB slot or PC card slot on the front face of the control panel.

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 collection box reduces the frequency of emptying. The optional workpiece conveyor discharges to the left front of the machine.

Coolant tank/chip collection boxA 150-litre coolant tank is standard, enabling extended periods of operation. The chip outlet port has been increased to improve chip removal. Optional chip conveyors are available to suit the type of chip material.

Adjustable operation panelThe pivoting operation panel enables easy operation whilst simultaneously viewing the machining process.

On-machine program check functionUsing manual hand feed, operations can be run in the forward or reverse directions, can be paused to edit the program, and restart.

Display of code listThe function displays the list of G, M, and T codes including explanations-useful aid to programming.

Easy viewing with text size changeTwo text size settings can be applied to each screen (large text display illustrated).

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.

Direct C-axis indexing functionDirect C-axis indexing enables deceleration direct to chosen index position eliminating the wasted time of performing zero return.

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.
