Alpha CNC4000XM - Fanuc 21i - TB

Driven Tooling   Fanuc 21i - TB Control   The Alpha System   Alpha Link CAD/CAM

The award winning Colchester-Harrison Alpha CNC4000XM manual/CNC lathe is the first Alpha ever produced with the capability for high-precision C-axis milling as well as metal turning. Effectively ‘two machines in one’, this milling option builds on the features of the XS making it a highly versatile and cost-effective machine for a wide range of advanced machining applications, with full contouring capability and positional accuracy of +/- 0.01º it is already proving highly attractive to specialist engineering tool-rooms in many countries.

Unique control software developed by our engineers to enable you to double, triple or even quadruple your productivity compared with other turning methods. The reason our Alpha System is so simple, practical and shop floor friendly is that our engineers are lathe specialists.

The Alpha System uses easily recognizable screen graphics along with simple question and answer prompts to guide you. It is also the reason that the Alpha System uses a touch screen, so you can work directly on screen rather than hunt for the right button to press.

Manual Turning

Turn the key and you are turning manually.  It’s as simple as that! The manual screen display shows X and Z positions just like a DRO plus spindle speed, tool number and feed rate.

Even if you haven’t used a lathe since your schooldays you could walk up to an Alpha X now and cut metal.

Semi-Automatic Turning

With the Colchester-Harrison Alpha System, a wealth of semi-automatic turning operations can be performed. These include parallel turning to stop positions, chamfers and radii, tapers, threads, grooves, box cycles and even contour shapes.  These can be linked together to produce even the most complex of components quickly and efficiently.

What’s more, the easy to understand shop floor language coupled with touch screen simplicity means that an operator can learn to machine parts quickly.

One of the advantages of the Alpha System is that you are always in control of the machine and you can manually override machining at any time to gain confidence or to hit the optimum tool performance.
