A reader struggles with burrs between intersecting holes 1 mm and less in diameter. MMS Online’s micromachining expert offers advice.
This small hole is actually large enough that any of three different processes might be used.
Micro Waterjet LLC offers a machine that overcomes the lack of positioning accuracy and limited cutting stream control that have historically barred waterjet from work at the micro scale.
Advanced micromachining capabilities have had a monumental effect on the way parts are produced. But as parts continue to get smaller, complexities increase, as do corresponding tolerance requirements.
Making micro sized parts is one thing; measuring them is another.
“Tiny” usually comes to mind when the term “micro” is used. So it is easy to assume that micromachining equates to very small parts found in the medical and electronics manufacturing industries.
