SCF Sigma – high productivity, low cost per cut
Maximum output through multiple cuts and extensive automation
The SCF-Sigma is a fully automated cutting machine, designed for maximum productivity and efficiency. By cutting multiple tubes simultaneously – up to 6 per cut – and thanks to a fully optimised process, this machine achieves an exceptionally high output. This shortens production times, keeps the cost per cut to a minimum and enables continuous and reliable production in large-scale applications.
Efficient processing of steel tubes, high volumes, high precision and low cost per cut. Bewo builds the integrated SCF Sigma production line to fully automate your production. Systems such as automatic bundle loaders, integrated product finishing, quality control and robotic packaging increase your output and reduce your costs.
The SCF Sigma can cut up to six profiles simultaneously. By servo-controlling the rotational speed of the saw blade and the feed rate, cutting times of less than one second are achievable, even when cutting multiple tubes simultaneously.
- High productivity,
- Suitable even for longer lengths thanks to the gripper with a stroke of 3,000 mm
- Low cost per cut
- Competitive tooling costs
- Maximum output: 12,000 pieces per hour
- Up to 6 tubes in a single cut
- Accuracy: 0.1 mm
- Conveyor speed 4 m/s
High-performance multi-cut
By utilising smart clamping devices and a powerful saw head, output is very high, whilst quality and accuracy are consistently maintained at a high standard.
Smart technologies, such as proportional cutting, ensure that, despite high hourly production rates, costs – for example, for saw blades – remain low. As a result, the final cost per cut is exceptionally low. For large volumes, the Sigma is consistently the best choice.
Examples of profiles that the SCF Sigma can process:
- Seamless round, square and rectangular tubes
- Welded precision tube
- Chrome steel tube
- Welded cold-drawn tube
- High-pressure pipes
- Solid bar stock: round, square, rectangular, flat
- Carbon steel, alloy steel, stainless steel
