The presetting machines available today are accurate, easy to use and provide closed-loop tool compensation on the CNC machine tool, saving significant time during job change-over.
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.
Moldmakers hoping to avoid problems such as chatter, poor tool life and molds that fail quality control muster need to consider a variety of factors when selecting a long-reach toolholder.
