Integrated Tube Cutting Line – Standard Configuration

The integrated tube cutting line is a fully automated system for the precise processing of tubes and profiles. It combines cutting, brushing/deburring, washing, drying, measuring, and stacking into one continuous process.
All workpieces are 100% inspected within the line for length, inner and outer diameter, and defective parts are automatically sorted out.

System Components

Bundle loading magazine

Tube separation unit

Sawing unit

Brushing and deburring machine

Washing machine with dryer

Length measurement control

Outer and inner diameter inspection (Keyence sensors, measuring mandrels up to 500 mm)

Stacking handling with magnetic gripper

Safety devices (protective fence, light barriers, etc.)

The bundle loading magazine is designed for tube lengths up to 9 m. The system allows for damage-free separation and positioning of the tubes. After cutting, the tubes are deburred, cleaned, dried, and automatically stacked for further transport.
