Band saw for plastic pipes Ø 630 mm (45° mitre cuts):
BSM 631
Do you require a robust and precise band saw for plastic pipes that can reliably handle all common angle cuts for standard fittings?
The BSM 631 is our proven, semi-automatic solution for diameters from 200 mm to 630 mm. Thanks to the double-sided mitre cut from 0° to 45°, you can create T-pieces and segments with maximum precision and efficiency – an indispensable tool for modern pipe manufacturing.
Product highlights
- Cutting range: Precise machining of pipe diameters from Ø 200 mm to 630 mm.
- Mitre cuts: Angle adjustment from 0° to 45° on both sides for all common T-pieces and segments.
- Safety & precision: Double-sided saw arm bearing guarantees exact cutting path and repeat accuracy.
- Full control: Infinitely adjustable electric feed for optimum cutting speed depending on the material.
- Easy handling: Angle scale and angle lock on the front for quick, error-free adjustment.

Highest precision thanks to double-sided saw arm bearing
Maximum angular accuracy is crucial in the manufacture of fittings such as T-pieces, elbows and segments. The BSM 631 is equipped with a double-sided saw arm bearing. This design minimises vibrations and guarantees a precise cutting path across the entire cutting area.
The double-sided mitre from 0° to 45° makes the machine extremely flexible for standard fittings. The bearings and precision guides work together to ensure optimum cutting performance and maximum repeat accuracy – even under maximum load.
Functions and advantages of the BSM 631 in operation
The BSM 631 electric band saw is designed for maximum user-friendliness and efficient process control:
- Optimal speed: The electric drive with infinitely variable feed rate allows you to perfectly adjust the cutting speed to the respective material (PE, PP, PVC, PVDF). This protects the saw blade and improves the cutting quality.
- Reliable process control: Thanks to the integrated cutting depth limiter, you can prevent accidental cuts and ensure consistent process reliability.
- Intuitive adjustment: The angle scale and lock on the front of the machine allow you to quickly and easily read and fix the desired cutting angle.
- Safety and clarity: The laser cutter detection shows you the exact cutting line on the workpiece, which makes positioning easier and reduces the error rate.
Options for maximum efficiency
Pneumatic clamping

For companies that produce large quantities, optimising set-up times is crucial.
The optional pneumatic clamping is the ideal addition to your BSM 631. It ensures that the plastic pipe is fixed quickly, securely and reliably throughout the entire sawing process. The pneumatic mechanism significantly reduces manual set-up times, increases process speed and improves safety for operating personnel. This leads to a measurable gain in productivity in daily operation.
