Uraohjaukseen

Uraohjaukseen is a Finnish term used in mechanical engineering to describe a class of guiding arrangements in which a moving component is constrained to follow a groove. The groove acts as a rail, and a matching guiding element—such as a pin, roller, or tongue—fits inside it to determine the path and limit lateral motion. The concept is commonly applied in machine tools, fixtures, and automated equipment to achieve accurate, repeatable motion along a defined line.

Typical implementations include grooves machined or formed into a bed or slide, with a mating follower or limiting member engaging the groove’s profile. Common groove types include straight, dovetail, and T-slot configurations, each offering different balance of load capacity, stiffness, and ease of assembly. The guiding element may run directly within the groove or be separated by low-friction bearings or bushings.

Uraohjaukseen is used to improve positional accuracy, reduce tilt (pitch and yaw) of the moving part, and simplify alignment during setup. It is often paired with lubrication and wear-resistant materials to extend service life. Debris and wear particles are typical maintenance concerns, as they can increase play and degrade accuracy.

Related concepts include linear guides, track-guides, and cam-follower systems. The term reflects a broader family of guided-motion technologies that rely on a physical groove or track to constrain movement and define contact geometry.
