Overview
The TFH-20CNC is the flexible all-rounder of the TFH family. Six cutter-head groups, the upper nylon cots and three pressure groups are under full numerical control, while front and rear separation cutter heads (3 segments each) correct forward/backward misalignment and the rear lower head adds 3-axis misalignment lifting. Special-shaped and misaligned profiles are adapted in minutes, not shifts.
The professional intelligent control system includes automatic nesting: scan the profile QR code and the data imports with one key, and every pressure parameter can be adjusted simultaneously or independently through servo motors. More than 2,000 profile programs stay in memory for instant recall.
Key Features
- 20-axis flexibility — six cutter-head groups, upper nylon cots and three pressure groups all numerically controlled.
- Super error correction — rear separation lower cutter head with 3-axis misalignment lifting; front and rear separation upper cutter heads adjust forward/backward.
- 80–100 mm strip compatibility with per-head width freely CNC-adjustable — no tooling change between strip widths.
- Fast straightening — nylon cots lift to correct bowed profiles and hold verticality and parallelism.
- Scan-to-produce — QR code one-key import with automatic nesting; 2,000+ stored profile programs.
- Solid drive train — linear guide rails, ball screws, Schneider electrics and simultaneous/independent servo pressure control.

Profile Misalignment States
The 20-axis configuration covers all three misalignment families with the fullest station setup of the mid-range machines.
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 misaligned and standard thermal-break sections in mixed series.
- Curtain-wall and facade profile lines with shaped sections and staggered strip grooves.
- 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.
