Overview
The TFH-14CNC adds a 3-axis CNC misalignment function to the proven 11-axis platform: the rear separation lower cutter head lifts up and down independently, so profiles whose strip groove sits higher on one side than the other — the common high/low-groove family — can be crimped without rework.
Everything else stays as forgiving as the base machine: six cutter-head groups numerically adjusted for 80–100 mm strips, nylon cots that straighten bowed profiles, and 2,000+ stored programs recalled with one button when the profile changes.
Key Features
- High/low-groove misalignment — rear separation lower cutter head with 3-axis CNC lifting compensates staggered grooves between upper and lower cutter heads.
- Six cutter-head groups under numerical control, adapted to 80–100 mm height insulating strips; nylon cots lift by CNC; three CNC pressure groups.
- 2,000+ profile memory — one-button positioning makes changeover between profile families fast and repeatable.
- CNC-adjustable cutter width — run different strip widths without changing cutters.
- Quick straightening — nylon cots correct bowed profiles and protect verticality and parallelism.
- Quality hardware — precision guide rails, precision ball screws, Schneider components and stepless speed regulation.

Profile Misalignment States
The 14-axis configuration covers the standard profile plus up/down misalignment between strip and profile.
Working Process
- Feeding — the knurled and strip-inserted profile enters the rolling station on the infeed conveyor.
- Positioning — the program recalls 14 axes. The rear separation lower cutter head lifts on three CNC axes, so a profile whose strip groove sits higher on one side is levelled by the machine instead of being shimmed by hand.
- Rolling & crimping — the cutter heads press the groove walls over the strip to the stored crimp value, and the lifted lower head holds both sides of a high/low groove at the same depth.
- Output — finished profiles leave straight and parallel, ready for packing, machining or the thermal break assembly line.
Quality & Standards
Every TFH machine is assembled and inspected above industry standard with a three-step pre-delivery inspection. On the 14-axis model the check adds a high/low-groove test piece with a 5 mm step between the two sides: crimp depth is measured on both sides and must match within the machine’s ±0.05 mm positioning accuracy, with no shimming. Rolled sections hold longitudinal shear to GB/T 5237.6-2017 and bending to the high-precision class of GB/T 5237.1-2017.
Applications
- Window and door plants whose catalogue includes high/low-groove sections — casement and awning families where the strip groove sits higher on one side.
- Plants crimping standard and offset profiles on one machine, without stopping a batch to shim the lower head by hand.
- Mixed-series production with several changeovers per shift; 2,000+ programs keep recall to one button.
Part of the TFH rolling & crimping range — five models from 11 to 37 axes. If your sections are offset front-to-back as well as up-and-down, the TFH-17CNC adds translating front upper heads.
FAQ
What is a high/low-groove profile?
A section where the PA66 strip groove sits at a different height on the two sides. On a fixed lower head one side is over-pressed and the other under-pressed, so the strip either deforms or never seats. The 3-axis lifting head compensates for the step automatically.
Can the TFH-14CNC still run standard profiles?
Yes — same 11.5 kW frame, same 6–60 m/min speed, same 2,000+ program memory. On a standard section the lifting head simply returns to zero, so nothing is lost by choosing this model over the 11-axis.
Do different strip widths need different tooling?
No. The upper and lower width of each cutter head is CNC-adjustable, so different strip widths within the 80–100 mm range run without changing cutters.
