Holding precision tolerances for your parts
are our #1 priority. The largest of our grinders is 16" wide
x 30" high x 96" long. Rotary surface grinding is also
at your service which can generate your concave or convex surfaces.
Where toolroom tolerances or special angles are required,
Columbia's reciprocating surface grinders are available. These machines
are also good on production runs, especially on small or thin pieces
(1/4" dia., .013" thick).
