Overview
The TKC-11CNC combines upper and lower knurling with PA66 strip insertion in a single 11-axis CNC machine. A traditional layout needs two separate machines and a manual 180° flip between them; this machine knurls the A-side groove and inserts the strip, then knurls the B-side and inserts — one load, one operator, no flipping.
CNC control covers knurling depth, tooth pitch and insertion speed, so the tooth pattern stays uniform across every batch. The machine saves floor space, removes the flip-damage risk entirely, and connects directly to rolling machines and conveyors for linked production.

Key Features
- Two machines in one — upper (A-side) and lower (B-side) knurling and strip insertion integrated into a single frame.
- No flipping, no re-clamping — one load completes both sides, removing flip damage and repositioning error.
- 11-axis CNC control of knurling depth, tooth spacing and insertion speed for different profile specifications.
- One operator for the whole process — major savings in floor space and labour versus a two-machine layout.
- Line-ready — integrates into existing production lines for linked, continuous operation.
- Standardised output — CNC automatic operation keeps tooth precision and insertion quality uniform across batches.

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.
- Workshops moving from manual strip insertion to CNC-controlled, one-operator production.
- 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.
Can it connect to a rolling machine?
Yes. The machine is designed for linked production — profiles pass straight from knurling and insertion into the rolling & crimping station without flipping or re-clamping.
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.
