Campbell Grinder Company proudly manufactures its 800 series creep feed grinders for superabrasive machining processes in the United States. Even though creep feed requires high metal removal rates and deep cutting action, our grinding machines stay accurate to within a micron, ensuring the manufactured parts are of the highest quality. 800A400 series grinders feature one of the smallest foot prints in our entire catalog and are ready to fit virtually anywhere.

This option allows for dressing the wheel straight and interpolating a form into the grinding wheel.
Roll form dresserA formed dressing roll allows for the final part form to be dressed into the wheel allowing shorter cycle times.
Crush dresserFree-wheeling form dress.
Spindle power up to 100HP and various RPM options.
Fire suppression system (for oil coolant)Certain applications require machining in oil. The spark risk is controlled through a fire suppression system. This includes a rapid deployment of the system once heat is detected and blast doors to force the remaining heat upwards and away from the operator. This creates a safe environment to operate in oil under extreme circumstances.
Part probeA part probe can be permanently mounted to the B-Axis for faster inspections of components.
Tool probeChecks the grinding wheel prior to the actual grind process to ensure accuracy.
Milling and drillingMilling and Drilling options are available to add auxiliary machining to the Campbell center.
Gap eliminatorGap elimination allows for the wheel to touch the part in a higher feed rate and then reduce to a feed rate for the specific grind.
Tool changerA tool changer is the most requested option. Storing multiple tools allows for many operations to be handled with a single clamping. Tool changers have been supplied with 40+ positions and can change the grinding wheel, Roll dresser, Turning tool, Milling tool, and Drilling tool for each cycle.
Wheel balance systemA wheel balancer is necessary when tight tolerances on surface finishes are required. Also, to extend wheel life.
Mist collectorA mist-free zone is required in many applications. Our mist collectors are sized specifically for the enclosure of each machine.
