Various Shapes and Sizes In Blind Cavities: Threads Into Hardened Materials, Molds, Hexes Into Bolts, and Keyways
There are many operations where Sinker/Ram EDM is the most efficient way to machine parts. Sinker/Ram EDM can be done in the vertical or horizontal position. We are able to even EDM parts upside down.
Extreme Accuracy and Fine Finishes
Tolerances of up to +/- .0001" can be achieved with very fine finishes.
Miniature Parts
400 pins were Sinker/Ram edmed. The coin shown is a dime, and the pins are .012 inch diameter to a depth of .030 inches.
Helical Gears
Orbiting machines can machine helical gears and shapes. Our Sinker/Ram EDM machines are capable of orbital, vectorial, directional, conical, horizontal planetary, cylindrical, helical, concave and convex spherical machining.
Production EDM
Since all our machines are computer numerically controlled (CNC), they are excellent for production work and repeatability.
Machining at an Angle
Sinker/Ram EDM is capable to machine parts on an angle.
Innovating Machining
By modifying machines, tall parts can be EDMed.
Heavy Parts
Work tank size on this machine is: X 79.5 inches, Y 126.7 inches, Z 53 inches. Table load is 66,000 pounds.
Tall Parts
Tall parts can be machined in large Sinker/Ram EDM machines.
