Wire EDM: Accuracy to +/- .0001 Inch
Snowflake is made from two pieces of steel. It takes 30 seconds or this 1“ snowflake to reach bottom of the surface plate.
Wire EDM: Machines Intricate Shapes
Wire EDM can machine all sorts of intricate shape into any electrical conductive materials, hard or soft.
A rotating chuck is programed with the wire EDM. As the chuck rotates, the wire can machine parts in the X and Y, and the top head can also move in the U and V.
Small Hole EDM
Drilling a hole on curved surfaces pushes away drills. Since EDM is a non-contact machining operation, holes can be easily drilled. Shown is a .010” electrode in a ball bearing. A dime is shown to see the comparison.
All sorts of blind cavities can be machined with sinker EDM. The vertical Z in many machines comes with the capability to move up and down and rotate. In addition the X and Y axis can be programed. Show is an electrode connecting two ports on a valve.
