What is Sinker EDM?
Sinker EDM (Spark Erosion; Die-Sinking) uses an energized shaped electrode in a submerged bath of dielectric fluid to machine conductive metals, and offers an efficient manufacturing method to produce complex part details that are difficult to machine by other methods.
Where is Sinker EDM best used?
Sinker EDM is used as alternative to conventional CNC machining for a variety of reasons, including:
- The creation of an exact mirror of the shape of the electrode within the component.
- Capabilities to work with a large variety of materials.
- Precision of delicate or intricate details without damaging the component material.
Are Sinker EDM machines limited to certain industries?
No. EDM machining benefits multiple industries including:
- Die & Mold
- Aerospace
- Medical
While EDM may be a slower process than conventional CNC methods initially, the production of highly accurate, repeatable parts with high-quality surface finishes offsets this, as there is less of a need to complete different machining processes on different machines, ultimately saving time. Sinker EDM excels at producing small deep features that are beyond the capability to mill to repeatable high accuracy.
Why Makino EDM?
What sets Makino EDM apart from other manufacturers is the ease of use. Operators of all skill levels can use the intuitive Hyper-i control system; an easily accessible high-definition touchscreen that functions much like a smartphone or tablet. This interfaced is identical across all Makino EDM machines: sinker, wire, and hole drilling, to ensure consistency and reduce training requirements by users.
With more than 140 patents, a Makino EDM means faster processing times and superior surface finishes for even the most complex part geometries.
With improved flushing and debris removal through an increase in the Z-Axis cycle jump rate, Makino EDM are four times faster with an acceleration rate 30 times faster than previous technology. This results in a reduction of electrode wear, and therefore, fewer electrode required.
