Mitsubishi EDM technology has long set the bar for quality, durability and innovation, and its sinker EDM machines are no exception. Built to the highest quality standards and designed to deliver cost-efficient precision, Mitsubishi sinker, wire and drill EDM machines drive manufacturing around the world.
When it comes to razor-sharp accuracy, nothing beats sinker EDM machines from MC Machinery. Advanced controls, EDM automation capabilities and a superior power supply make these sinker EDM machines the ideal choice for tight-tolerance applications, including die and mold.
SINKER EDM TECHNOLOGY
Sinker EDM (also referred to as conventional or ram EDM) utilizes a custom-made electrode that “sinks” a shape into a material. Sinker EDM allows you to produce intricate shapes without stressing the material.
Electrodes appear as a reverse, or negative, of the required shape. As with all EDM services, the tool-electrode degrades with use, which requires additional electrodes for long-run sinker applications.
Unlike wire EDM, sinker EDM does not cut all the way through the material (unless desired). As a result, sinker EDM has a wider variety of applications, such as blind cavities/keyways, thin walls, or cross sections, making it a versatile and efficient choice for stamping dies and injection molds.
EDM TECHNOLOGY: WIRE VS SINKER VS DRILL
All EDMs use an electrical current to cut material; it’s how the current is used that differs.
Wire EDM utilizes a thin wire to discharge the electric current sent into the electrically conductive metal workpiece. Both the wire and workpiece sit beneath a layer of dielectric fluid. It acts as a cathode in the process, generally cutting completely through the material with extraordinary precision. Wire EDM is ideal to machine complex, intricate and highly accurate tooling.
Sinker EDM uses an electrode, an insulating fluid, and a power supply. The power supply connects the electrode and the workpiece. The spark resulting from the connection produces a channel. Unlike wire EDM, sinker EDM do not cut completely through the material, allowing for the production of complex shapes without affecting material integrity. Sinker EDM is ideal for producing blind and high aspect ratio pockets, injection molds and stamping dies.
EDM Hole Drilling is a unique and quick way to produce semi accurate holes in conductive materials regardless of their hardness at relatively high speeds. Unlike a wire EDM, which uses a wire to cut, an EDM drill uses an energized rotating tube electrode with high pressure flushing to “burn” a hole through conductive material for faster, more accurate machining.
WHY BUY MITSUBISHI EDM
Innovation is the name of the game at Mitsubishi, with sinker EDMs designed to independently accelerate burns when conditions are appropriate, conserve electrode wear without operator intervention, or adjust current shape to meet exact discharge requirements.
Sinker EDMs from MC Machinery almost think for themselves: by adjusting on the fly, these innovative sinker EDMS are able to turn out the highest quality parts in optimum cycle times across multiple applications, no matter the electrode shape, material or cutting conditions.
The Mitsubishi EA series features high-accuracy, high-grade sinker EDMs you can trust for micro-fine finish, mold & die, or small-hole applications. Designed with highly durable components to keep maintenance costs in check, the EA series is as reliable as it is versatile. Adaptive controls, such as the Power Master GF2 Adaptive control reduces graphite electrode wear, specifically in sensitive graphite electrode burns, by as much as 80% for less downtime and minimized maintenance and part replacement. Fast machining, accurate cuts and energy savings make this series a valuable investment for any shop.
Not to be outdone, the Gantry Eagle series comes with a host of advantages all its own. For example, independently responsive controls, such as the world’s first Adaptive Current-Shape generator, make this line of sinker EDMs a must for high capacity, high precision machining. The generator calculates and creates the ideal current shape for the exact discharge requirements of each pulse. Rough machining speed is doubled while spark gap is reduced resulting in reduced electrode wear, enhanced accuracy and superior finish. Thermal stability, rigidity, all-around work area access: Gantry Eagle sinker EDMs provide a flexible, state-of-the-art EDM machining solution for the tool and mold industry.
MC Machinery sinker EDMs are best-in-class when it comes to power, precision and profit. Equipped with a suite of standard options to save time and money, these machines are built to excel in modern sinker applications.
For example, intuitive Fuzzy Pro Plus software examines pulse and conditions to make incremental amperage adjustments, decreasing or increasing amperage without burn interruption. By adjusting the machining settings in degrees following burn trends, the machine efficiently removes the most material possible for high-performance, unattended sinker EDM machining.
Temperature sensors continuously monitor ambient conditions to regulate thermal displacement, resulting in highly precise machining, regardless of the environment or operator experience.
Mitsubishi sinker EDM machines include revolutionary power supply technology which reduces electrical consumption by 20% as compared to previous generations, while machine stabilizing jump controls reduce the load on less rigid electrodes by ensuring smooth jump-up movement for stabilized machining and increased speed.
