Wire EDM machine uprated to cut quicker
Fanuc has extended the capacity, specification and performance of its Robocut Alpha-1iA wire cut electro discharge machine (EDM) to provide high accuracy performance cutting at up to 300mm2/min.
Fanuc said that compared with the earlier VMC, the Alpha now drills larger holes in steel.
Two, the Alpha has a high speed toolchange mechanism (patent pending) giving a 'chip-to-chip' time of just 1.6s in the machine's range of working.
Available from 600 Centre in Shepshed, Loughborough, UK, the 'F' Series machine range, comprising the Fanuc Alpha T14 and T21iF, is delivered with 14 and 21 tool magazine capacities.
The Compact, Standard and Extended (FL) versions have X-axis travels of 300mm, 500mm and 700mm respectively.
An important aspect of Fanuc's VMCs is that they achieve high productivity, said the 600 Centre.
They do this by combining fast axis movements and rapid accelerations.
The 'F' Series has fast axis feedrate of 54m/min and acceleration of 1.5G.
The new main spindle allows larger drills and combination tools to be used, for example: step tools for chamfering.
A high speed 24,000 rev/min spindle is also available as an option.
As part of the Fanuc development programme, a fourth axis unit with built-in, backlash-free synchronous servomotor drive provides a rotational speed of 150 rev/min.
This unit takes just 0.4s to index 180 deg.
* Five axis machining - for 5-axis machining applications the high specification Fanuc 31i-A5 control has 3D cutter compensation along with 3D contouring compensation to offset thermal displacement effects.
Using NURBS interpolation software, Fanuc's A1 contour control with 200 block advanced read ahead has an option of 1,000 block advance.
Included in the specification is high speed rigid tapping up to 8,000 rev/min with quick extraction cycles.
It enables an override up to 20 times the normal infeed rate, said 600 Centre.
The Fanuc Alpha T14 and T21 are available in three sizes each with a Z-axis travel of 330mm, as follows.
* The Compact has 300mm in X and option of either 300mm or 400mm in Y.
* The Standard has a working envelope of 500mm in X and 300mm in Y.
* The 'FL' has 700mm in X and 400mm in Y.
