Carbon steel orbital tube-cutting machine SCF Sigma

coldhigh-speedCNC

Product overview
The SCF Sigma is a fully automated tube cutting saw engineered for continuous high-volume production. It performs multiple simultaneous cuts (up to 6 tubes per cut) with servo-controlled blade speed and gripper feed, minimising cycle time and cost per cut while ensuring repeatable dimensional accuracy.

Key features

• Multiple simultaneous cutting: up to 6 tubes per cut
• Maximum output: up to 12,000 pieces/hour (project dependent)
• Accuracy: 0.1 mm (for Ø < 25 mm)
• Saw blade max diameter: 400 mm; saw motor: 9 kW
• Gripper stroke: 3,000 mm; transport speed: up to 4 m/s
• Hydraulic multi-clamping and servo gripper feed

Performance and processing
The machine combines intelligent clamping, a powerful saw head and proportional cutting strategies to maximise throughput and extend blade life. Servo regulation of blade rotation and feed ensures short cut times (below one second in optimal conditions) and stable quality in high-volume runs.

Examples of profiles that the SCF Sigma can process

• Seamless round, square and rectangular tubes
• Welded precision tubes; chrome steel and cold-drawn welded tubes
• High-pressure pipes
• Solid bar stock: round, square, rectangular, flat
• Materials: carbon steel, alloy steel, stainless steel, non-ferrous materials
