Hochleistungs-Reibsystem DR

Friction system for drilling from 7.6 to 140.6 mm

The friction system DR und DR small of horn is now in the most common sizes stock. With the uncoated or coated friction cutting tool system has proven for years rubbing tasks with a diameter of 7.6 mm to 140.6 mm. The secure attachment and positioning of only 4.3 and 5.3 mm wide friction cutting of tungsten carbide or Cermet on the respective base support ensures a change of accuracy related to the concentricity ≤ 3 µm. In addition to numerous application of customized geometries can the user select almost for every cutting task the optimal combination of substrate, coating and geometry. Small allow the friction systems DR and DR reaming of holes using small cutting fabric, economically, accurately, and in very high speed. The efficient use of carbide or Cermetschneiden help to reduce cost per hole.
The friction system DR camp program includes following variants: for H7 holes 12 to 50 mm diameter in mm increments, and for holes from 52 to 100 mm diameter in eleven other sizes. Each size is available with two geometries. Straight teeth for blind holes and left helical teeth for through holes. ALCrN coating is of steel and cast iron with a very high hot hardness and a high resistance to oxidation when editing. Other positive features are the very good sliding properties and the low tendency to glue. With the standard friction cutting, also brass and bronze alloys can be economically machined. The system DR small, the smallest modular quick change friction system in the world, is available in four sizes for reaming diameter from 7.6 to 13.1 mm. Also DR small is in straight H7 dimensions ex stock available. Various cutting materials, cutting - and shank covering a very wide field of application also in the small friction system.

With the system DR small Horn leads the world's smallest patented quick-change friction system in the program. The diameter ranges of four system sizes ranging from 7,600 mm up to 13,100 mm.
It allows quick and uncomplicated change of friction cutting machine with high repeatability. High flexibility in cutting materials, cutting and Schaftsystemen covers a wide field of application. DR small reduces the cost per hole considerably, increases productivity and reduces the logistics costs due to system of change of elimination of Regrinding cost. The precise connection between shaft and interchangeable head is marked by grooves and springs. It allows a high power transmission with a removable precision of less than 5 µm. The fixing of the Exchange cut via a central clamping screw. Tops in steel or carbide available in versions for through holes or blind holes. They differ essentially because of the way of the inner coolant supply. DR small, the system for the grinding of small diameter, is therefore the economic and technical alternative to Carbide reamers.
