4-Flute vs 5-Flute End Mills for Titanium: Which One Boosts Productivity?

Leave a Comment / End Mill for Mold Steel / By

Recently, a CNC supervisor from Munich, Germany, sent us a video of an on-site operation: a new 5-axis machining center was cutting Ti-6Al-4V (TC4) aerospace parts with high-pressure internal coolant. The cutting noise was piercingly sharp. Within twenty minutes, chatter marks appeared on the workpiece, and the tool’s flank face showed severe built-up edge (BUE) […]

High Speed Milling of Graphite Using Diamond Coated End Mills for Precision Machining Applications

Leave a Comment / Graphite Machining System / By

In real-world manufacturing, producing high-precision graphite electrodes in volume presents a distinct challenge. As demand for higher efficiency rises, traditional graphite milling methods quickly reveal their limitations. High-speed machining with standard carbide tools often leads to rapid tool wear, thermal variations, poor surface finish, and severe dust contamination. We recently collaborated with a mold manufacturer

Roughing Endmills for Steel in Mold & Die Manufacturing: Best Practices

Leave a Comment / Cutting Tools / By

During a technical consultation with the chief process engineer at a long-established German mold manufacturer, he showed us several worn-out roughing endmill for steel tools. Every single cutter exhibited severe micro-chipping and thermal cracks on the cutting edges. They had been machining an H13 die-casting mold (HRC 48–52) for an automotive headlight bracket.
