FAQ
SW-400 Questions
Answers to common questions about the SW-400.
Any electrically conductive material regardless of hardness — hardened tool steel, carbide, titanium and other exotic alloys cut cleanly since the process erodes material with electrical discharge rather than mechanical cutting force.
The SW-400's automatic threading system re-threads the wire and resumes the cut without operator intervention in almost all cases, which is critical for unattended overnight runs.
Standard 208-230V three-phase power and a water supply for the dielectric system; our install team confirms exact requirements and drain considerations during your site survey.
Yes, on-site training covers wire threading, taper programming and dielectric system maintenance, with follow-up classes available at our Vaughan Tech Centre.

sinker EDM
SE-600
The SE-600 is Sparion's sinker (die-sinking) EDM, purpose-built for burning deep cavities, sharp internal corners and fine surface detail that no cutting tool can reach mechanically. A 400 x 300 x 300 mm travel envelope, a 600 kg workpiece capacity and a 0.1 μm servo head resolution let it hold electrode positioning tight enough for mold cavity and core work at Ra 0.05 μm best finish. Tollaston sells the SE-600 into mold, die and precision tooling shops that need to complement their wire EDM capability with cavity-sinking for closed-end pockets a wire simply can't cut. The oil-based dielectric and automatic level control keep the process stable through long unattended finishing burns.
