Abstract
A method for producing a mechanical locking system for a first panel and a second panel. The method includes providing a tongue, including a first locking surface, at a first edge of the first panel, forming a tongue groove, including a second locking surface, at a second edge of the second panel, the first locking surface and second locking surface are configured to cooperate for locking the first edge to the second edge in a first direction, providing a first guiding surface at the first edge and a second guiding surface at the second edge, wherein the first guiding surface cooperates with the second guiding surface during an assembling of the first edge and the second edge, and working of the first guiding surface and/or the second guiding surface to reduce the coefficient of friction between the first guiding surface and the second guiding surface and/or a surface roughness.
