10,200 complex components; incorporating 61,200 sprung arms, each attached to a circular platform with a precision pierced 0.1mm diameter hole in the centre; for delivery in 48 hours. This was a challenge asked of Precision Micro, Europe’s leading photo chemical etching company.
The customer had already dismissed laser cutting as a possible solution because of the time it would take to profile the parts, the possibilities of thermal distortion and the possibility of underside burrs being generated using this single point ablation profiling method.
Stamping was also ruled out as this technique was unable to produce the holes with the required 1:1 aspect ratio, even if the precision tool could have been produced in time. The material in question was a Sandvik special alloy that is notorious for causing tool wear.
Using LEEP (Laser Evolved Etch Process) technology, Precision Micro was able to meet the customers.
