EDM Machining – Makino says its new wire EDM UP6 machine improves performance, increases productivity and can machine with better part accuracies.
Featuring a hollow casting, parts of Makino's new UP6 is flushed through with dielectric water at constant temperature to prevent the machine suffering from heat displacement. The arm seal plate is constantly cleaned by a water curtain to reduce friction and ensure smooth operation in the X-axis. Very long, high-precision roller slides reduce motion vibrations and improve rigidity. High-precision ball screws are covered to prevent dirt ingress and extend their lifespan. According to the company, its new wire drive allow for better corner accuracy, more reliable wire threading in complicated shapes and small start holes. Also, the new automatic wire threading system now enhances threading capabilities and works dry as well as with water jets.
New CAM software
The company's new CAM software EDCAM 2017 allows for several automatic tasks. Among them are creating and adding cavities from a 3D model, ascertaining all electrode positions, recognising and calculating spark areas, recognising and acquiring depths, finding measuring points and recognising workpieces. The main benefit is thus, minimising input errors. New features of the Hyper i Control operating panel are smartphone, tablet-style flick, pan, pinch, spread and swipe functionality. Moreover, EDCAM data is editable at the machine control interface and machine settings can be automatically downloaded.
Makino's upgraded EDAF series now has a newly developed generator, the company's first implementation of its H.E.A.T. technology for sinker-EDM and a programmable flushing control. The improved EDAF comes with higher feed rates of up to 5,000 mm/min in the X and Y-axes. Another feature, HS-Rib, enables a jump speed of 20m/min in the Z-axis – a 31% increase over the current model. This more powerful generator has a 80A-peak current in standard, while reducing power consumption by 44%.
Makino CEO Dr. P. Anders Ingemarsson said: “The upgrades and extensions to our EDM portfolio have considerably improved their appeal to machining companies targeting a wide range of industries.”
Application fields for Makino's EDM portfolio are the die and mould, electronics, food and packaging, health and cosmetics and precision metalworking.
