British lathe specialist T S Harrison has significantly enhanced its successful Alpha XT Manual/CNC lathe range with the introduction of 'Operations Link' software, which now offers operators further important advantages in time-saving, automatic linking of operating cycles and workshop efficiency. Technical designers at Harrison, part of the internationally-renowned 600 Group machine tools company based at Heckmondwike, West Yorkshire, have worked closely with the market-leading control systems provider, G E Fanuc, to develop this new software. 'Operations Link' will be incorporated on all newly-supplied Alpha XT machines.

It is also being offered to existing Harrison XT customers free of charge as an easily-installed update.

The four-version Alpha XT range (XT 1350, XT 1400, XT 1460 and XT 1550), is equipped with Fanuc's latest Oi TC Mate control which enables no fewer than 40 advanced, individual machining cycles to be programmed and stored, using the system's Fanuc TurnMate i conversational shop floor programming.

Now, thanks to the launch of 'Operations Link' these cycles can be linked together to create a fully-automatic and continuous machining sequence from start to end, without the need for the lathe operator to tend the machine or switch between cycles.

Philip Stockdale, technical support engineer at T S Harrison, said: 'The early versions of the Alpha XT required the operator to complete each operation and then move from one cycle to the next.

For example you might want to create cycles for a facing operation, followed by a rough and finish turning cycle, and then a threading cycle.' He said: 'Fanuc and Harrison engineers have created the ability to link together these separate operations to produce a complete program, which operates the whole sequence completely automatically with just one press of a button which makes it more like a CNC machine.' The second major benefit of 'Operations Link' is that multi-cycle programs can be transferred via a memory card and stored on a PC for future use - or, crucially, for off-line programming/simulation of complex parts and safety-checking prior to machining.

Furthermore, up to five of these complete programs can be stored on the Alpha XT's Oi Mate control itself, for maximum operating flexibility.

Stockdale explained: 'For small to medium numbers of turned components, the new software speeds up the all-important 'floor-to-floor' time, especially when the Alpha XT lathes are used with the multi-station tool turret.

For these types of turning operations, the quicker and easier it is to complete the machining, the better and more cost-effective it becomes for the toolroom.' He added: 'There are also important benefits in programming time, because large numbers of complete turning programs can be stored.

Operators can create a directory of complete programs on their PCs, which can be downloaded onto the lathe again and again.' As well as Fanuc TurnMate i conversational programming, the advanced Alpha XT lathe range features the ability to switch to full ISO (CNC) functionality.

All Alpha XT customers also receive Harrison's 'Alphalink' CAD/CAM software which is a fully Windows-compatible system for flexible off-line programming.
