General Info

Serving the Pacific Northwest since 1979

Grind All’s mission is to operate with the principles of quality and on time delivery. We have begun the journey to quality excellence through the implementation of our Quality Assurance Program.

Grind-All is able to achieve dimensional tolerances and surface finishes that are impossible with machining alone.        


Behind Office Depot, just off SR167


Centerless Grinding

Centerless Grinding is an OD grinding process where the part is not physically held at its centers, achieving a round surface tolerance with surface finish and dimensional tolerances that are impossible to achieve with machining alone.


Parts - .060” diameter to 5.0” diameter

Long Bar - 12’ bars to a maximum diameter of ¾”

Cable  - up to 40’ long at a .00005 tolerance

Tolerance:  .0005 /.0002

Finishes:  to better than 4 micron finish

Outer Dimension

(OD) Grinding


OD grinding is performed on external surfaces of an object between the centers. The centers are end units with a point that allow the object to be rotated.


Up to 14” diameter x 60” center to center.  Overall weight is a determining factor on the size of part we can accommodate

Tolerance:  .0005 /.0002

Finishes:  to better than 4 micron finish

Internal Dimension

(ID) Grinding


ID grinding occurs on the inside of an object. The grinding wheel is always smaller than the width of the object.


      Parts as long as 24-28” long.  We can hold .0002 concentricity and a 4 micron finish with tight tolerance .0002. We can also provide face grinding with .0002 flatness.


Tolerance:   .0005 /.0002


Finishes:  to better than 4 micron finish


 Precision Honing

Honing produces a precision surface on a work piece. The process is primarily used to improve the geometric form of a surface, but may also improve surface texture.  High-precision parts are usually ground and then honed. Grinding determines the size, and honing improves the shape


All types of materials

From .175” to 3” Bores

Holding .0002 tolerance with 4 micron finish

Max Length 15” long   

Surface Grinding

 Surface grinding is used to provide precision ground surface, either to a critical size or for the surface finish


Up to 12” x 24” on magnetic chuck. Larger parts must be blocked and evaluated on a case by case basis 

Tolerance:  within .0002

Finishes:  to better than 4 micron finish

Flatness:   within .001 per foot

Cylindrical Grinding

 The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes however, the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.






14” x 60”  center to center.  We can grind angles, radius, grooves or length while holding .0002 tolerance. 

Tolerance:  .0005 /.0002

Finishes:  to better than 4 micron finish



Tolerance:  .0005 /.0002

Finishes:  to better than 4 micron finish
