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.
New Cutting Tools Unveiled
Among the 10 products being introduced in the U.S. for the first time are the 109 type Supermini series grooving and boring tools and the S100 cutting insert with internal cooling.
Road Report: Wish You Were Here, Day 4
This year, the volcano in Iceland didn’t stop Chris Koepfer, editor-in-chief of Production Machining magazine, from visiting grooving tool maker P.H. Horn for its Technology Days open house and seminar in Tubingen, Germany.
Complete Machining Products
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 Tooling Solutions
Horn USA offers Solutions Plus, a combination of the company’s custom tooling solutions for difficult machining applications and a guaranteed 2-week delivery with free overnight shipping. The company indicates when a tool is available for the program on its official quotation.
Milling System Uses Triple-Edged Indexable Inserts
The DA multi-milling system offers solutions for face milling, corner milling, plunge and pocket milling, chamfering and pre-drilling tasks. The system’s positive geometry helps reduce the risk of vibration because the tools and drive units are only slightly loaded. Diameter-specific inserts with helical reliefs ar
Horn USA Celebrates 10th Anniversary
This year marks the 10th anniversary of cutting-tools manufacturer Horn USA, which is located in Franklin, Tennessee. The Horn USA headquarters occupies approximately 25,000 square feet and can grind over 50,000 cutting tool inserts per month for grooving, parting-off and small-boring applications. A subsidiary of
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.
