Working principle
How precision sectioning works
A rotating cut-off wheel advances into the specimen under flood coolant, keeping heat and deformation low enough to preserve the true section.
- Wheel matched to material
- 4-channel coolant
- Low feed rate protects edges
Product overview
The QG-4T uses a manual lever-operated cutting arrangement for specimen preparation. Its floor-standing configuration includes a recirculating cooling system intended to manage cutting heat and help reduce burning of the cut surface. The machine is aimed at small and medium laboratories preparing conventional metallographic and petrographic samples, with a straightforward operating approach for routine sectioning work.
