Micro-machining of 0.050 mm Micro Holes on a Makino V22 Vertical Machining Center

This micro fluid metering plate features (61) 0.050 mm holes drilled into a 0.50 mm thick 303 stainless steel plate. Micro-machining was performed on a Makino V22 vertical machining center equipped with a 0.050 mm micro drill. The machine's rigid spindle construction combined with a high precision collet holder assembly and Makino's hybrid ATLM tool tip contact sensor enabled successful machining of all 61 holes.

This test was conducted at Makino's micromachining R&D facility. For more on micromachining visit http://www.makino.com/micro and view our latest case studies.

What is the resolution and repeatability on a V22?

[MakinoMachineTools]

@douro20 Thanks for the inquiry. The V22 offers linear positioning accuracy of plus-or-minus 0.0015 mm (0.000060") with 0.05 micron scale feedback (*with proper foundation and environmental control*). It can hold repeatability within plus-or-minus 0.001 mm (0.000040").

What always amazed me more than the machined part itself, was HOW THE F*CK WHERE THE MICRO-DRILLS MACHINED IN THE FIRST PLACE ! Let alone the collects, mills, etc.
