At the heart of Spectra-Tech is creep-feed grinding

Creep feed Grinding, well established in Europe to meet quality and tolerance specifications, creep-feed grinding continues to grow in America. It replaces not only other forms of grinding, but also milling.


Some areas of successful applications are:

• Aerospace

• Automotive

• Electronic

• Medical

• Tool and Die Manufacturing


The materials adaptable to creep-feed grinding are many. They include: soft and hardened exotic alloys, steels, aluminum - even carbide, ceramic and plastics.


Rapid stock removal is accomplished by profile grinding with a crush roll, diamond roll, or by CNC dressing to the desired work piece configuration.


Other benefits include:

• Grinding can be done after heat treating, elimination distortion.

• Extremely tight tolerances are held throughout production runs.

• Most parts are finished by the grinding process - the need for deburring or other operations is minimized or eliminated.


Our creep-feed grinders are the finest in the industry. A key quality creep-feed production is proper featuring. At Spectra-Tech we have the engineering expertise to design or consult on fixtures or gages best suited for your project. Efficient fixturing also allows creep-feed grinding to be used effectively for short- run production.
