Emuge-Franken USA has introduced PunchDrill, a new drill design that offers high feed drillingwhich doubles the feed rate compared to standard drills without increasing axial force or spindle speed.
Emuge-Franken says the benefits of PunchDrill include:
- reduced machining forces
- reduced machining times
- optimized chip-breaking
- cycle time savings of 50 percent or more when machining cast aluminum alloys with at least seven percent Si content and magnesium alloys
- reduced tool changes
- improved metal removal rates
- increased productivity
- reduced power consumption.
“At a time when aluminum usage is steadily growing, we are pleased to offer our customers the fastest drill available on the market – another innovative Emuge cutting tool solution that significantly saves time and enhances productivity,” said Bob Hellinger, president of Emuge-Franken USA.
PunchDrill features patent-pending geometry with a chip breaker that produces short chips to control machining forces. The new drill also has newly developed surface treatments and a hard diamond-like coating specially designed for this application to provide reliable chip removal and increased process reliability. When high-speed PunchDrill is used at the recommended feed and speed, axial force is reduced by half. The increase of the feed at the same rotational speed results in a significant decrease of machining time with less machine wear, while retaining tool life. This in turn reduces machine power consumption, saving costs and supporting sustainability.
The self-centering capability of the drill tip on PunchDrill optimizes positioning accuracy on holes. PunchDrill is available in drilling depth ranges up to approximately 8 x D, the nominal diameter range from 0.129″ to 0.472″ (3.3 mm to 12 mm). Machining is done with a normal drilling cycle on CNC machines with cutting speeds and coolant pressures similar to conventional drilling. Even on unstable parts and clamping, PunchDrill can perform with greater process reliability. PunchDrill can also perform as a step tool.
