Used VIGERT VMC-855L Machining Center For Sale

VMC-855L Machining Center. A machining center, often referred to as a CNC machining center, is a type of manufacturing equipment used in modern machining processes for the production of precision components. It is a highly automated and computer-controlled machine tool that can perform a variety of machining operations with high precision and efficiency.

Here’s a comprehensive description of a typical machining center:

1. Machine Structure and Components: VMC-855L Machining Center. A machining center consists of a sturdy machine structure, typically made of cast iron or other high-strength materials, to provide stability, rigidity, and vibration dampening. It comprises several essential components:
   • Bed or Base: VMC-855L Machining Center. The foundation of the machine that provides stability and support for other components.
   • Column:VMC-855L Machining Center.  A vertical structure that supports the spindle head and houses the Z-axis movement components.
   • Spindle Head: VMC-855L Machining Center. The unit that holds and drives the cutting tool. It can move in the X and Y directions.
   • Tabelle: The work surface where the workpiece is securely held during machining. It can move along the X, Y, and Z axes.
   • Werkzeugwechsler: An automated tool-changing system that stores and selects various cutting tools for different machining operations.
2. CNC-Steuerungssystem: The heart of the machining center is the CNC control system. It includes a computer and software that controls the movement of the machine components and the cutting tools. The CNC system interprets the part program (G-code) and generates the necessary signals to move the spindle, tool changer, and table accurately.
3. Axis Movements: A typical machining center operates in three or more axes:
   • X-Achse: Horizontal movement along the length of the machine.
   • Y-axis: Horizontal movement along the width of the machine.
   • Z-Achse: Vertical movement of the spindle head and tool.
4. Werkzeuge und Werkzeughalter: Machining centers utilize a variety of cutting tools for different operations such as milling, drilling, tapping, and more. Tool holders securely grip and position these tools, allowing for efficient tool changes.
5. Automation and Tool Changer: Machining centers are equipped with automatic tool changers that can hold multiple tools. The tool changer selects the appropriate tool for the specific machining operation, enhancing productivity and reducing downtime.
6. Workholding Devices: Different workholding solutions, such as vises, fixtures, or chucks, are used to secure the workpiece firmly to the table during machining.
7. Anwendungen: Machining centers are used across various industries, including aerospace, automotive, medical, and more, to produce complex and precise parts like engine components, aerospace structures, medical implants, and mold components.
