Knurling machines are used knurled or ridged surface in the bond zone of a composite profile. A knurled groove significantly increases the grip and the bond between two connected profiles. Knurling is therefore a cost-efficient way to optimize the static strength of profiles.
Profiles are knurled with the compound grooves facing down. Mainly used in the combined knurl/assembly process. Optionally CNC controlled, which shortens and simplifies the change over. By combining the LK1 and LK2 machines, the aluminum profiles can be processed by the knurling machines at the top and bottom at the same time. With this combination you get a fully automatic system, which increases the production time and the automation.
