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.


Through-feed Grinding
Our in house Alplanalp grinders offer our customer's quality through-feed grinding. It gives us the capacity to economically grind large volumes of parts normally produced on Blanchard, surface or Double-Disc grinders.


OD Grinding (plunge form)
We can handle parts with forms 3-in. wide and a 4-in. OD. Our machines are Model 10 CNC - equipped Sheffield crush-form grinders.


Our Equipment
The type of grinders we operate include:
• Creep-feed
• Surface
• Through-feed
• OD

These precision grinders have up to 110 HP at the spindle. Most have programmable controls for fully automatic cycles.
