The STMDRAGON STM-S4-3220 4 Axis CNC Bridge Saw Machine is designed for precision cutting and processing of stone materials in professional stone fabrication and processing operations. Its 3200 × 2000 mm worktable, 360 mm saw blade, 15 kW saw motor, and 4-axis configuration support accurate cutting and specialized stone-processing applications.
The machine supports 0°/45° blade tilting for standard cutting, four-sided chamfering, plane grooving, and basin/sink hole cutting. The worktable can tilt from 0–85°, helping operators load and unload large stone slabs more conveniently.

Main Functions & Applications
The STM-S4-3220 can be used for automatic stone slab cutting, 45° angled cutting, four-sided chamfering, plane grooving, basin/sink hole cutting, and other stone-processing operations. It is suitable for professional marble, granite and other stone fabrication and processing applications, subject to the final tooling and material requirements.
The machine can also be configured with optional infrared positioning and camera systems to improve cutting-position identification and operational accuracy. An automatic suction-cup system can assist with moving stone slabs and reducing interference from saw cuts.
Electrical & Configuration
The machine is specified for 380V / 3 Phase / 50Hz power with an 18.5 kW inverter and 15 kW saw blade motor. Final electrical installation requirements should be confirmed according to the machine configuration and installation location before ordering.
