Applications & Industries

Graphite EDM Electrode Manufacturing

The used Makino V77 GRAPHITE is designed for high-speed milling of graphite electrodes used in electrical discharge machining (EDM). It supports the production of complex electrode geometries, detailed contours, and tooling features required for precision mold manufacturing.

Precision Mold and Die Making

This CNC graphite machining center is suitable for electrode production in plastic injection mold manufacturing, die-casting tooling, automotive molds, and other precision mold-making applications.

Large Graphite Workpiece Machining

With a 1,400 × 700 mm worktable and 1,200 mm X-axis travel, the V77 GRAPHITE provides a practical machining platform for larger graphite electrodes and multiple-workpiece setups. Actual machining capacity depends on workholding arrangements and available clearance.

High-Speed Graphite Milling

The 20,000 RPM spindle configuration supports high-speed cutting strategies for graphite components with intricate features, fine details, and complex 3D contours. Machining results depend on tooling, cutting parameters, spindle condition, and material characteristics.

EDM Workshops and Tooling Manufacturers

For EDM service providers, mold shops, and industrial tooling manufacturers, a second-hand Makino V77 GRAPHITE can be a cost-conscious option for expanding dedicated graphite machining capacity.

FAQ

What is the difference between a Makino V77 and a V77 GRAPHITE?

The Makino V77 GRAPHITE is designed specifically for graphite machining applications. Compared with a general-purpose vertical machining center, the graphite configuration emphasizes dust management and protection of important machine components against graphite contamination. The actual equipment fitted to a used unit should be confirmed before purchase.

Can this used Makino V77 GRAPHITE machine large EDM electrodes?

Yes, the specified 1,400 × 700 mm worktable and 1,200 × 700 × 640 mm axis travels support a range of medium-to-large graphite electrode machining applications. The actual workpiece size will depend on fixture height, tooling, and machining clearance.

Are EROWA ITS tooling and electrode holders included?

The supplied equipment information lists EROWA ITS workholding components, electrode holders, and related accessories. Please confirm the final inventory, quantities, and included equipment before purchasing.
