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-4A is intended for preparing conventional metallographic and petrographic specimens. Its automatic cooling tank supplies cooling during manual cutting. The design applies ergonomic principles to the operating arrangement, with an emphasis on convenient handling and low-noise operation. It provides a manual sectioning approach for laboratories preparing metal and rock specimens, with cooling incorporated into the specimen-cutting process.
