At EMO Hannover, Paul Horn will demonstrate high-precision machining on four advanced machine tools, highlighting techniques for lead-free materials, aluminium and complex components. Visitors can also explore the company’s latest tooling developments, including the new sintered chip breaker geometry for challenging materials.

On its 580 square metre stand, number A32 in Hall 5, at this year’s EMO exhibition in Hannover, cutting tool manufacturer Paul Horn will show live machining on four different machine tools. There will be a pair of lathes, an Index G220 fixed-head model and a Citizen L12 sliding-head turning centre, while two 5-axis machining centres, a DMG Mori DMU65 Monoblock vertical-spindle model and a Grob G150 horizontal-spindle machine, will put Horn’s prismatic machining tools through their paces.

Markus Horn, Managing Director of Paul Horn said: “We will be presenting machining at the highest level on the four machines. Demonstrations will include high surface finish machining, machining of lead-free materials, aluminium machining with rotating polycrystalline diamond 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 be presenting 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 particularly aimed at machining materials having poor chip formation properties. It is suitable for copy turning, longitudinal turning, back turning and facing.

Especially when taking a shallow depth of during the machining of steels and stainless steels, the tool system with this geometry demonstrates superior chip control, leading to high process reliability and long tool life. When developing the I-geometry, Horn 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.
