Engraving -From Burrs to Clean Edges. A successful story in Semiconductor industrial.
 |
In the semiconductor industry, the components are often made from non-ferrous or delicate materials such as aluminum, copper, stainless steel, or ceramics. Cooling by dry, air blow or fine-mist coolant is commonly used to avoid coolant residue contamination. Flood coolant is rarely applied as it risks affecting cleanroom environments or sensitive parts. A customer previously using carbide ball nose tools faced burr formation along the engraved edges of aluminum (Al6061), requiring manual deburring and secondary finishing that slowed down the production. Tests were conducted under dry, coolant, and air blow conditions at spindle speeds from 10000 to 15000 r.p.m. and feed rate between 200/300/600 mm/min. Result: ● Both 45° and 60° engraving inserts achieved clean engraving with minimal burrs. ● By dry or coolant usage both improved chip evacuation and surface finish. • 15,000 rpm / 300 mm/min (Dry cutting) • 15,000 rpm / 600 mm/min (With coolant) -> double the feed rate. ● Cycle time reduced up to 3× faster compared to baseline conditions. Now, the customer switched to the Nine9 X060 engraving tool, the improvement was impressive. Win! ● Nine9 X060 engraving tool – one holder supports 30° / 45° / 60° / 90° engraving inserts. Good potential for mass engraving works needing various widths and depths. Grades are available for steel and hardened steel and non-ferrous metal. ► To learn more >> Nine9 Engraving Tool |
