Live demonstrations on Horn stand at EMO 2025

On its 580 sq m stand (A32, hall 5) at this year’s EMO exhibition in Hanover, cutting tool manufacturer Horn will show live machining on four different machine tools. An Index G220 fixed-head lathe, a Citizen L12 sliding-head turning centre, a DMG Mori DMU65 monoBLOCK five-axis vertical machining centre and a Grob G150 five-axis horizontal machining centre will put Horn’s prismatic machining tools through their paces.

The company’s managing director Markus Horn says: “We’ll be presenting machining at the highest level. Demonstrations will include high surface finish machining, machining of lead-free materials, aluminium machining with rotating PCD tools and high technology component production requiring numerous sequential turning operations. In my opinion, the best results are achieved through dialogue and EMO offers the ideal platform for this.”

In addition to live machining, Horn will present numerous tooling innovations. Among them is the Mini system with sintered chip-breaker geometry, which was unveiled for the first time at the Horn Technology Days in May 2025. The sintered I-geometry is aimed at workpiece materials withpoor chip formation properties. It is suitable for copy turning, longitudinal turning, back turning and facing.

Especially when taking a shallow depth of cut during the machining of steels and stainless steels, Horn reports that a tool system with this geometry demonstrates superior chip control, leading to high process reliability and long tool life. When developing the I-geometry, the company also took into account the machining of lead-free materials, which are being phased out owing to their toxicity. As their replacements pose a challenge due to their inferior chip formation properties, the tool manufacturer offers inserts with small corner radii, starting from 0.05 mm for small lateral infeeds. Corner radii from 0.05 mm to 0.2 mm are available from stock.
