Overview
The TFH-11CNC is an 11-axis CNC rolling & crimping machine for thermal-break aluminium profiles. After knurling and PA66 strip insertion, the profile and the insulating strip are permanently locked together by precision rolling — the step that decides the shear strength, thermal performance and long-term stability of the finished thermal break profile.
Six groups of cutter heads, the nylon pressure rollers and three pressure groups are all positioned by CNC. More than 2,000 aluminium profile programs are stored in the control system, so a change of profile is a one-button recall instead of half an hour of manual re-adjustment. Precision guide rails, precision ball screws, Schneider electrical components and stepless frequency-converter speed control keep batch after batch consistent.
Key Features
- 11-axis CNC adjustment — six cutter-head groups, nylon rollers and three pressure groups positioned numerically for repeatable, batch-consistent crimping.
- One-button changeover — more than 2,000 aluminium profile programs stored in memory; recall saved parameters instead of re-adjusting by hand.
- Free strip-width adaptation — the upper and lower width of each upper cutter head is CNC-adjustable, so different strip widths run without changing tooling.
- Built-in straightening — nylon cots move up and down to straighten bowed profiles and hold verticality and parallelism after pressing.
- Misalignment ready — the rear separation lower cutter head (3 segments) is manually adjustable for profiles with staggered grooves.
- Industrial-grade hardware — precision guide rails, precision ball screws, Schneider electrics, servo pressure control and stepless speed regulation.

Working Process
- Feeding — the knurled and strip-inserted profile enters the rolling station on the infeed conveyor.
- Positioning — stops, presses and pushers center the A-side profile, insulating strip and B-side profile for precise alignment.
- Rolling & crimping — servo-driven cutter heads press the groove walls over the strip to the standard crimp value.
- Output — finished profiles leave straight and parallel, ready for packing or machining.
Quality & Standards
Every TFH machine is assembled and inspected above industry standard with a three-step pre-delivery inspection. Rolled profiles hold longitudinal shear force to GB/T 5237.6-2017 and bending to the high-precision class of GB/T 5237.1-2017, with high batch consistency and a low defective rate.
Applications
- Aluminium window and door profile plants crimping standard thermal-break sections in mixed series.
- Profile shops upgrading from manual or electric crimping machines to full CNC control.
- Factories that need repeatable changeover between many profile programs on one machine.
FAQ
Which axis configuration do I need?
It depends on the misalignment states of your profile cross-sections. Standard profiles run on the 11-axis machine; up/down and compound misalignment needs 14–37 axes. Send us your profile drawings and we will confirm the right configuration.
How fast can we change profiles?
More than 2,000 profile programs are stored. Recall the saved program and the machine positions itself — no manual re-adjustment of cutter heads or pressure.
Do different strip widths need different tooling?
No. The upper and lower width of each cutter head is adjustable, so the machine runs different strip widths without changing cutters.
