Anatomy of a High-Feed Insert
An examination of Horn’s recently expanded DAH series sheds light on the design features that make high-feed milling inserts effective. These particular tools also offer their own advantages.

Event Highlights Growing, Diverse Tool Supplier
Horn’s biennial “Technology Days” proved aptly named, as attendees were treated to a wealth of technical information. That included a tour of a new carbide plant where “green” inserts are shaped via extrusion and injection molding.

Indexable Inserts from Powder
During the 2013 edition of its biennial “Technology Days” event, Horn treated the press to a tour of its entire manufacturing operation. Here are a few highlights.

Horn’s System DR Reaming system features narrow cutter inserts for precision machining of steels, cast materials, non-ferrous metals and plastics. The DR product, produced under license from Urma AG, is available with cutting edge diameters ranging from 0.465" to 5.518" (11.9 - 141 mm).

Tech Days and the Volcano
On April 17, I was ticketed on a flight from Atlanta to Stuttgart, Germany at the invitation of cutting tool maker Horn USA. Unfortunately, the eruption of the Eyjafjallajökull Volcano disrupted my trip.

More Effective Groove Milling For Gearboxes
A cutting tools supplier developed a grooving tool with an 18-inch gage length and a radial runout of just 0.004 inch. That tool enabled a gearbox manufacturer to increase its groove milling feed rate tenfold for a hard-to-reach bore.

Custom Tools For Critical Grooves
This tier-one auto supplier pooled metalworking talents to develop custom groove milling tools to deliver the accuracy and finish necessary for precision brake caliper grooves.

Widening Range Of Grooving Tools
Traditionally, a grooving tool grooves, a facing tool faces and, of course, special tools do special cuts. Improved insert manufacturing technology and toolholder design is changing this tradition, allowing specialized tooling to be used more generically in a wider variety of metalcutting applications.
