NOTE ON FEED SYSTEM:

The F.P. Miller Co Re-manufactured Blanchard A series grinders use the Allen-Bradley Compactlogix PLC to control machine functions and motion control. Mating the PLC with an A-B touch screen, simplifies the set up and allows the operator full control of the grinding process.
Components are connected via Ether Net cables for the quickest response time, coupled with an A-B servo motor for accuracy.
Both Continuous and Impulse feed types are available with feed rates of .001 to .100 inches per minute in Coarse feed and .0001 to .010 inches per minute in Fine feed, with the Auto Cycle Function Repeat, cycles for production runs are available. With the simplified setup process single run grinds are done with a minimal amount of time. The operator panel will have hard buttons to control the machine functions: Magnet, Wheel, Head Jogging, Chuck rotation, Table Traverse and Coolant pump. Use of a panel mounted HIM allows variable RPM control of the Chuck.
