Maumee Pattern has CNC machined hardened steel tooling in unattended fashion since 1987. Today Vertical and Horizontal machining is performed 24 hours a day, 7 days a week on Makino's latest high speed machining centers with travel up to 2000 x 1200 mm. State of the art R.P.M., speed and feed rates must be witnessed to be appreciated. Delivery times are greatly reduced while at the same time improving surface finish and virtually eliminating hand work.

High Speed CNC machined graphite electrodes provide an extremely accurate and stable medium to transfer graphite shape into steel, stainless, iron, or aluminum without the use of cutters. Electrode wear is minimized by use of a finisher electrode. Any impact of wear is further reduced by compensation in the spherical orbit.

Graphite (carbon) is CNC machined undersize according to planned spark gap and orbit. Large computer controlled sparks rough burn. Spark length is reduced as the finisher electrode polishes the cavity and nearly eliminates the need for hand work. Tooling tolerance +/- .002" (.05mm) can be held even in deep draw areas because cutter deflection is not an issue. Maumee Pattern can CNC-RAM-EDM tooling up to 1500mm x 1100mm in size.
