EDM Die-Sinking and Drilling Machines
QMT supplies precision EDM die-sinking and small hole drilling machines for Australian toolmakers, mould makers, and precision engineers. Every machine in this range is built by a reputable & proven manufacturer and backed by local support.
What Is EDM Die-Sinking?
EDM die-sinking (also known as ram EDM or spark erosion aka “sparker”) is a non-conventional machining process that uses a shaped electrode to erode material from a conductive workpiece. The electrode and workpiece are submerged in dielectric fluid, and controlled electrical discharges remove material to form a negative impression of the electrode shape.
Die-sinking EDM is widely used for:
- Complex cavity machining in moulds and dies
- Intricate detail work in hardened or exotic materials
- Precision components for aerospace, medical, and automotive applications
- Textured surface finishes that are difficult to achieve with conventional cutting
What Is EDM Drilling?
EDM drilling (also known as hole-popping or fast hole drilling) uses a rotating tubular electrode and deionised water to produce small, accurate holes in conductive materials, regardless of hardness.
Common applications include:
- Start holes for wire EDM operations
- Cooling holes in turbine blades and injection moulds
- Air passages and venting holes in hardened dies
- Blind hole tapping in tool steels and carbide
