Overview
The TKC-7CNC is the lower-side specialist. Paired with an upper knurling machine, it takes profiles straight from the upper station — no 180° flip, no repositioning — and finishes the B-side groove and strip insertion. Skipping the flip removes the bumps, scratches and tooth damage that turning causes, and keeps the whole line flowing continuously.
Seven CNC axes adjust knurling depth, pitch and angle to the profile specification. The machine works with ordinary roller conveyors and standard support racks, so it drops into an existing line without special tooling or layout changes.
Key Features
- Lower-side specialist — profiles flow straight from the upper knurling machine without a 180° flip.
- No collision, less scrap — no turning means no knocks against machines or racks; surfaces and tooth precision stay intact.
- No special pallets — works with ordinary support racks and standard conveyors, no extra investment.
- 7-axis CNC precision — knurling depth, spacing and angle adjust precisely to each profile specification.
- Continuous line logic — designed for linked production with upstream and downstream equipment.

Working Process
- Load & clamp — the profile is sensed and clamped automatically at the knurling station.
- Knurling — CNC-controlled cutters roll a uniform tooth pattern into the strip groove, raising contact friction.
- Strip insertion — the PA66 strip is fed and clamped into the knurled groove in the same pass.
- Outfeed — the finished profile continues to the rolling machine or buffer rack without repositioning.
Quality & Standards
Precision square guide rails, precision ball screws and Schneider electrical components keep the machine stable around the clock. Combined with CNC automatic operation, tooth precision and insertion quality stay uniform from the first profile to the last in every batch.
Applications
- Aluminium window and door profile plants inserting PA66 strips into thermal-break sections.
- Profile shops pairing an upper and lower knurling machine into a continuous two-station line.
- Lines that need fast changeover across many profile families and strip widths.
FAQ
Which profiles can it handle?
The CNC-adjustable cutter covers strip widths and groove heights within the specification table above. Send us your profile drawings and we will confirm compatibility before you order.
Do I need a special support rack?
No. The TKC-7CNC works with ordinary roller conveyors and standard support racks, so it drops into your existing line without extra investment.
What about changeover between jobs?
Profiles are sensed and parameters recalled automatically — most changes need only a one-button reset instead of manual strip-height tuning.
