EMO 2023
Precision machining of bores
Paul Horn is presenting an innovative extension for the Supermini system in the field of ultra-fine machining at EMO 2023. The system has been supplemented by a variant with an ultra-fine ground cutting surface.
In combination with the precision grinding of the cutting edge profile, the tool cutting edge is virtually free of nicks. The tool system can be used from an inside diameter of 0.3 mm. The sharp cutting edge geometry enables a reliable cut even with very small infeeds and feed rates. The specially developed coating is suitable for stainless steels, non-ferrous metals and other metallic materials.
The cutting insert of the Supermini type 105 system requires only one tool carrier for well over 1,000 variants of cutting inserts. This applies equally to left-hand and right-hand versions. The carbide cutting inserts are available in coated and uncoated versions in different grades for every application up to hard machining up to 66 HRC. The patented teardrop shape of the cross-section has a vibration-damping effect and enables high repeat accuracy when changing the cutting insert. Internal coolant supply up to the cutting edge increases tool life, improves cutting conditions and chip removal. Horn offers the tools with face clamping elements for face clamping. This makes it easy to change the insert, for example, without having to remove the holder.
In 1989, Horn presented the Supermini system for the first time at the world's largest trade fair for metalworking, EMO in Hanover. With considerable development effort, it was possible to develop grooving tools for the internal machining of bores up to 5 millimetres in diameter. The Supermini system was born and became one of Horn's most successful products over time. In addition, the Supermini system was the first precision tool to be given Horn's own coating.
