Tenkku Precision Grinding specializes in CNC cylindrical external and internal grinding. We have the capabilities to hold the tightest tolerances and surface finishes by using our precision equipment coupled with over 35 years of grinding expertise. We have the equipment to run small prototype quantities or large production runs. Our machines are capable of a wide range of sizes, however we specialize in grinding smaller diameters and lengths with more complex features.

Cylindrical External (OD) Grinding Capabilities

  • Diameters from 0.030"-6.000" Diameter

    o Specializing in 0.030"-1.500" Diameter

  • Shaft length capacity to 39"

    o Specializing in shaft lengths < 6"

  • Tolerances to .00005"

  • Cylindricity to .00002" (.5 micron)

  • Concentricity to .00004" (1 micron)

  • Surface finishes to 2 micro inch

  • CNC Cylindrical Center Type grinding allowing for multiple diameters, angles, tapers, or radius grinding to be completed in one machining operation.

Cylindrical Internal (ID) Grinding Capabilities

  • Diameters from 0.030"-6.000" Diameter
