Description

The S 420 DI is a semi-automatic horizontal band saw designed for cutting large steel tubes, profiles, and solid bars in fabrication and industrial environments where increased capacity and controlled automation are required. Its rigid saw frame, hydraulically regulated cutting motion, and automatic head return support consistent cut quality while reducing operator effort between cycles.

The DI operating configuration provides a semi-automatic cutting cycle using hydraulic control for both the cutting descent and the return of the saw head to its raised position. This setup improves productivity while maintaining direct operator oversight and a mechanically robust design.

– Semi-automatic band saw operation with hydraulic cutting descent and hydraulic head return.
– Variable speed inverter allows blade speed adjustment to suit material type and cross-section.
– Supports straight and miter cutting for heavy fabrication and structural applications.
– Reduces operator fatigue by automating head movement between cuts.
– Rigid saw structure and heavy-duty vice clamping support stable cutting of large sections.

Operating Cycle:
Cycle start is initiated by the operator after material positioning and clamping. Once activated, the machine performs the following operations automatically during each cutting cycle:
1. Closing of the material vice and activation of the blade motor.
2. Cutting head descends under hydraulic control, regulating cutting pressure throughout the cut.
3. The cut is completed and the blade motor stops.
4. The cutting head returns automatically to the raised position under hydraulic control.

Common Uses:
The S 420 DI is used in heavy fabrication, structural steel processing, and industrial production environments where larger material sizes and repeatable cutting cycles are required. Its semi-automatic operation makes it well suited for shops seeking higher capacity and productivity than manual band saws while retaining controlled operator involvement.
