Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option.
Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.
