DLTUPR650 series - Roughing Application

Literal statement:
We offer a variety of high performance carbide roughing designs. The Rough-Tech is designed specifically for steel and aluminum alloy milling, solid or coolant fed, with a coarse tooth profile. The Aero-Rough (RS100 U/F) incorporates a truncated roughing tooth profile for maximum efficiency in aerospace alloys such as stainless steel, titanium and Inconel. The Rough-tech 48/56 (GS100 U/H) is designed for roughing materials up to 48 HRC and 56 HRC respectively and a coolant.
Features:

• Suitable for roughing of steels & cast iron (≤ 60 HRC).
• Special chip-breaking cutting edge design, for roughing applications.

Attention:

• Make sure work piece and machine are stable and use a precision holder.
• Please adjust the speed,feed and cutting depth according to actual cutting conditions.
• The milling conditions are for an end mill where the tool overhang length is less than 4*D(mill diameter). When the tool overhang length is longer, please adjust the speed,feed and cutting depth.
