Centre d'usinage à portique OKUMA MCV-AII-R

A OKUMA MCV-AII-R Gantry Machining Center, also known as a gantry machining centre (in British English), is a type of machining center distinguished by its design and structure. It utilizes a gantry-style architecture, characterized by a bridge-like frame or structure that spans over the work area. The gantry typically supports the machine’s major components, such as the spindle, tool changer, and other associated systems.

Here are the key features and components of a OKUMA MCV-AII-R Gantry Machining Center:

1. Gantry Structure: The gantry is a large, rigid structure that bridges the machine’s work area. It provides support for various components and allows for movement along the X, Y, and sometimes Z axes.
2. Bridge: The horizontal beam that connects the columns on either side of the gantry, forming the top part of the gantry structure.
3. Columns: Vertical structures that support the bridge and guide its movement along the X-axis. They provide stability and rigidity to the overall gantry.
4. Table de travail: The worktable is typically positioned below the gantry and can move along the X and Y axes. It holds the workpiece and allows for multi-axis machining operations.
5. Broche: The spindle is a high-speed rotating component that holds cutting tools and performs various machining operations such as milling, drilling, and cutting.
6. Changeur d'outils: Similar to other machining centers, a gantry machining center often has an automatic tool changer that can hold multiple cutting tools and change them automatically during the machining process.
7. Contrôleur CNC: The CNC controller interprets programmed instructions and controls the movement and actions of the gantry machining center, including the spindle, tool changer, and worktable.
8. Guides linéaires et vis à billes: These components guide the movement of the gantry and worktable, ensuring precise and smooth motion along the X, Y, and Z axes.
9. Système de refroidissement: A coolant system is used to cool the cutting tools and workpiece during machining, improving tool life and machining efficiency.

OKUMA MCV-AII-R Gantry Machining Centers are favored for their stability, high precision, and ability to handle large and heavy workpieces. They are commonly used in industries such as aerospace, automotive manufacturing, die and mold making, and large-scale production where precision and productivity are critical. The gantry design allows for efficient machining of large parts and complex geometries by providing a spacious and accessible work area.
