Pushing tolerances beyond the limit
Holding tolerances on diameter size and cylindricity to the sub-micron
level – with Ultra-Precision Centerless Grinding we work closely with
engineers who require a much higher level of precision for many of their
high-tech parts. We use only new CNC grinding equipment because today’s tolerances require today’s technology.

Ultra-Precision Centerless Success
Aerospace - spool/sleeve match fits to .000050" (1.2 micron)
Mass Spectrometry - quadrupoles
Semi-Conductor - pick & place tooling
Prosthetics - spool/sleeve match fits to .000050" (1.2 micron)
High Pressure Hydraulics - spool grinds to .00005" (1.2 micron) cylindricity
Unique Capabilities
-
Diameter tolerances to +/-.000020" (20 millionths) (.5 micron)
-
Roundness to .000010" (10 millionths) (.25 micron)
-
Cylindricity to .000040" (40 millionths) (1 micron)
-
Surface finishes to < 2 Ra (.05 micron)
-
We strive for six-sigma capability on all applications
-
Centerless Thrufeed and Infeed – straight parts or parts with a head
-
Diameter sizes to .750"*
-
Lengths to 10"
-
Work with difficult materials; Tungsten, Titanium, Nitinol, Molybdenum, Exotic Alloys (Inconel, Hastelloy)
*Parts much larger than .750 x 10” can be ground, but sub-micron tolerances become much more difficult to hold as the part size grows. For parts larger than .750" x 10” please see PrecisionCenterless Grinding.
