EDM - When Milling Just Won't Cut It

When conventional milling reaches its limits, Electrical Discharge Machining (EDM) provides the solution. This highly controlled, repeatable process uses energized spark erosion to machine conductive materials of any hardness with extreme precision. Makino EDM excels at machining harder workpiece materials and intricate part features that would be difficult—or impossible—to achieve through traditional milling.

Makino EDM technology benefits industries such as die & mold, medical, aerospace, electronics, military, and general manufacturing. While EDM may be slower than conventional machining, it offers unmatched accuracy, repeatability and fine surface finishes. Plus, it’s easily automated for unattended, 24/7 production, maximizing efficiency without increasing labor costs.

Why Choose Makino EDM?

What sets Makino apart from other EDM solutions? Ease of use and superior performance. Our machines feature an intuitive, large HD touchscreen interface—so simple, it operates like a smartphone. The advanced Hyper-i control system provides a consistent interface across Makino Wire EDM, Sinker EDM and EDM Drilling machines, dramatically reducing operator training time.

Beyond usability, Makino EDM machines require half the maintenance of competing models, consume fewer machine consumables, reduce cycle times, and operate faster—delivering greater productivity and lower overall costs.

Discover how Makino EDM can transform your machining capabilities.

Types of EDM Machining:

Sinker EDMs 

• Sinker EDM machines are ideal for hardened materials and complex part details that are difficult to machine by other methods. The EDM process uses a charged, shaped electrode in a submerged bath of dielectric fluid to machine conductive materials. The sinker EDM machine sinks the electrode into the workpiece, removing particles through spark erosion. 
• Makino Sinker EDM machines stand apart because of their improved speed, lower electrode wear, reduced cycle times and finer finishes. They’ll increase your part production and profitability.

Wire EDMs 

• Traditional wire EDM machining consumes more than one pound of wire per hour, making wire consumption the biggest expense of operating wire EDM machines.  
• Some of our wire EDM machines can cut at twice the industry standard speeds without increasing wire consumption.
• Our wire EDM machines utilize advanced adaptive control technologies that automatically adjust for workpiece thickness while maintaining excellent part accuracy and straightness with the industry’s lowest wire consumption rates.  
• A Makino wire EDM machine reduces wire consumption by up to 50% less over competitive models, providing a significant long-term savings in $1,000’s of dollars per year in operating cost.

EDM Hole Drilling 

• EDM machining for hole drilling uses an energized rotating tube electrode with high pressure flushing to produce fast, accurate machining of small, deep holes in conductive materials.
• Makino EDM hole drilling technologies achieve reduced cycle times and increased accuracy with advanced machining break-thru detection.  
• Makino offers EDM Drilling machine solutions designed for small diameter high-precision applications, and high-volume production machining of cooling film holes for turbine engine components.
