Thin-wire EDM below 0.15 mm is machine-dependent. Evidence from three configurations shows stable 0.10 mm cutting when the machine is converted for the wire size, the correct wire technology is selected, and flushing is controlled. A separate AGIE 200 configuration with an HSS generator handled 0.05 mm wire, but workpiece-thickness limits were reported without numerical values.
Separate Wire Capability from Process Stability
Do not treat wire diameter alone as proof that a machine can run the process. Confirm the transport hardware, threading capability, generator strategy, and permitted workpiece thickness for the exact machine. On a Charmilles Robofil 1020si, 0.10 mm wire reportedly cut copper, carbide, and hardened tool steel with rare wire breaks when the correct wire table and effective flushing were used.
Cutting time with 0.10 mm wire was reported as not significantly longer for a single cut because the wire removes a 0.10 mm-wide section. Treat that as configuration-specific experience rather than a guaranteed production rate. The evidence provides no hourly rate, so estimate cost only after measuring setup time, cutting time, intervention time, and wire consumption on the intended job.
Compare the Documented Machine Configurations
| Machine configuration | Wire diameter | Required preparation | Automatic threading | Reported result |
|---|---|---|---|---|
| Charmilles Robofil 1020si | 0.10 mm | Select the correct wire table, keep the upper nozzle close to the workpiece top surface, and flush effectively | Not available with this wire in the reported configuration | Stable cutting with rare wire breaks |
| AGIE 200 with HSS generator | 0.05 mm | Install suitable components, including special wire transport belts, and use AGIE-specified strategies | Available in the reported configuration | Smooth operation, subject to unspecified workpiece-thickness limits |
Threading behavior is not transferable between machines: the Robofil configuration could not automatically thread 0.10 mm wire, while the two AGIE configurations could. With 0.05 mm wire, initially routing the wire through the transport belts was difficult because visibility depended strongly on lighting.
Configure and Verify a Thin-Wire Job
- Confirm that the exact machine configuration supports the intended wire diameter. Identify any required transport components or minor conversions before loading the wire.
- Load the manufacturer-provided wire table or machining strategy for that wire size. Do not substitute settings intended for a larger wire.
- Route the wire through the transport system. Improve task lighting when handling 0.05 mm wire because the wire may be difficult to see.
- For the documented 0.10 mm Robofil setup, position the upper nozzle close to the workpiece top surface and establish effective flushing.
- Run a controlled cut and verify stable transport, acceptable flushing, and the absence of repeated wire breaks. If automatic threading is required, test it on the installed machine configuration rather than assuming support from the wire diameter alone.
- Measure actual setup and run time on the target material and thickness before setting an hourly rate. No supported rate or universal thickness limit is available from the evidence.
FAQ
Can a wire EDM cut reliably with 0.10 mm wire?
Yes, the documented Charmilles Robofil 1020si and AGIE 200D configurations both ran 0.10 mm wire stably. Success depended on machine preparation, the correct wire strategy, and controlled flushing.
Can wire EDM automatically thread 0.10 mm wire?
It depends on the machine configuration. Automatic threading was unavailable on the documented Robofil 1020si setup but available on the AGIE 200D after its thin-wire preparation.
What setup is required for 0.05 mm EDM wire?
The documented AGIE 200 with HSS generator required modifications including special wire transport belts and AGIE-specified strategies. Automatic threading worked, although initial manual routing was difficult when lighting made the wire hard to see.
