OD / Cylindrical Grinding

Valley Tool has the expertise to provide Cylindrical Grinding services of the highest quality.

Our decades of experience in cylindrical grinding combined with the most advanced CNC technology offers accurate and precise grinding for applications from single piece prototypes or reworks to large scale production applications.

Cylindrical grinding is ideal for parts with single or multiple diameters that need to run concentric with each other. It is also ideal for outside diameters with slots or other features that cause an interrupted cut.

Our CNC dressing units and rotary dressers can produce complicated profiles, radii and spherical radii.

Dimensional accuracy and location of critical areas are enhanced, during the grinding cycle through in-process gauging on many of our cylindrical grinders.

We pride ourselves in using only the best cylindrical grinders, including our newest addition, the 2011 Studer S33 CNC Grinding Machine.

Surface Grinding

By surface grinding, we achieve flat, square, and parallel surface finishes on parts up to 12" x 24" in size. Achieving surface finishes 8 RMS or better, is not a problem for us. With our ability to hold grinding tolerances to 0.0002" you know you will receive the quality you need to optimize your final product. When the flatness of the surface is critical, trust our experienced craftsmen who understand the intricacies involved in grinding metal to this level of precision. We offer quick turn-around on our OD / Surface Grinding services, including 24-hour rush service.



Honing

honing

Valley Tool specializes in the highest quality bore sizing and micro finishing for all industrial applications. We hone prototypes as well as production work on all types of materials.

Honing is a specialty internal bore finishing process that provides exceptional roundness, surface finish, as well as bore sizing accuracy and precision.

The rotational and stroke movement of the honing tool produces a bore action that removes peak points present on the inside of components.

  • High Precision bore sizing
  • Roundness to .000030 Max

Features

  • Close tolerances
  • Surface finish to 4 RA
  • Precision Sunnen Hones& Gauging
  • Minimal lead times

Tolerances

  • Diameter tolerances to .000050
  • Straightness to .000050 Max
  • Roundness to .000030 Max
  • Surface Finish to 4RA
