Endless wire saw
Requirements list
-
Cut to be performed with constant wire speed
-
Use of small segments of diamond wire
-
Possibility to find the same diamond grains for wire wear investigation
-
Low waste of workpiece material
-
Possibility to increase cutting speed higher than 30 m/s
-
Possibility to use different cutting fluids
-
Possibility to change distance between rotatory axes to control eventual wire vibrations
-
Clear vision of the cutting gap and wire bow
-
Controllable wire tension
-
avoidance of non-cutting wire wear (damage caused by the wire-wire contact)
Ultra-precision lathe to be reconfigured
Based on the requirements list, it was identified the opportunity to build a new endless wire saw test rig by the reconfiguration of an ultra-precision machine tool. The machine is fully based on aerostatic bearing technology and features two axes of movement and a rotary air bearing (yates bearing).
