The MAST Metalltechnik M-BS 450TURN is a high-performance metal bandsaw machine, specifically engineered for precision cutting of large-scale metal stock. This cutting machine combines a rigid gravity-fed design with an advanced hydraulic control system, making it indispensable for production facilities and metalworking shops.
NOTE: This model features a SWIVEL FRAME (miter head), not swivel vises. This allows for angle cutting without moving or rotating heavy workpieces, significantly saving workshop space and reducing operator labor.
Key Functional Blocks and Advantages
Hydraulic Control System
The machine utilizes a hydraulic downfeed cylinder for smooth, controlled lowering of the saw frame. The operator can precisely adjust the descent speed, ensuring uniform blade contact and protecting teeth from premature wear or chipping.
Industrial Induction Drive
The 2.2 kW 3-phase motor is designed for heavy-duty 2-3 shift operations. The induction design provides stable torque even when cutting viscous alloys or large solid bars.
4-Speed Transmission
Mechanical speed adjustment via belt drive (25/ 40/ 51/ 71 m/min) is more reliable than electronic frequency inverters, as it maintains full motor power at low RPMs — a critical factor for cutting tool and stainless steels.

Saw Blade Specifications
Cutting stability in the M-BS 450TURN is guaranteed by the use of professional-grade blade standards:
- Blade Dimensions: 3300 x 27 x 0.9 mm. The 27mm width minimizes blade deflection during deep cuts.
- Tensioning: An integrated pressure gauge (manometer) allows for precise blade tensioning, preventing breakage and ensuring straight cuts.
- Guide System: Carbide inserts combined with roller bearings ensure perfect vertical alignment and minimize vibration.

Frequently Asked Questions (FAQ)
Why does this professional bandsaw weigh 340 kg?
Mass equals rigidity. The heavy cast iron base and steel frame absorb vibrations, which directly improves the surface finish of the cut and extends the life of the cutting blade.
What is the purpose of the automatic shut-off?
Once the cut is complete, a limit switch stops the motor. This allows a single operator to manage multiple machines simultaneously without worrying about the blade running unnecessarily.
How does the coolant system help?
The flood coolant system flushes chips away from the teeth and cools the friction zone. Without it, the blade would overheat and lose its tempering within the first few hours of operation.
