Holding tolerances on roundness, straightness, and/or diameter size 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.
Industries/applications served by high-end precision grinding:
Spool/Sleeve match fits to .000050" (1.2 micron) – Aerospace, Prosthetics & High Pressure Hydraulics
Rods ground for the Mass Spectrometry Industry
Motor Shafts for the manufacture of Hard Drives Anything that needs to spin fast or have a close fit!Special features and capabilities include:
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"** 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 Precision Centerless Grinding.
Throw your tightest tolerances at us! We’ll show you that we’re up for the challenge!
We buy only new CNC grinding equipment – today’s tolerances require today’s technology.
