VIGERT Used Machining Center For Sale

A Used VIGERT 855 Machining Center, often referred to as a CNC (Computer Numerical Control) machining center, is a highly automated and versatile machine tool used for a wide range of precision machining operations. It combines several machining processes, such as milling, drilling, tapping, and sometimes even turning, into a single machine, controlled by a computer. Here’s an overview of the key components and functions of a Used VIGERT 855 Machining Center:

Key Components:

1. Machine Bed or Base: The machine bed forms the foundation of the machining center, providing stability and support for the entire machine. It’s typically made of a heavy, rigid material, such as cast iron, to minimize vibrations during machining.
2. Broche: The spindle is the part responsible for rotating the cutting tool. It can rotate at high speeds and often features various toolholders for different types of cutting tools. The spindle speed and direction are controlled by the CNC system.
3. Changeur d'outils : A Used VIGERT 855 Machining Center is equipped with an automatic tool changer (ATC) that can hold multiple cutting tools. The ATC automatically selects and changes tools as needed during machining operations, reducing downtime.
4. Table de travail: The worktable is where the workpiece is secured for machining. It can have various configurations, including rotary tables, pallet changers, and multiple axes of movement. The worktable’s movement is controlled by the CNC system.
5. Toolholders: Toolholders secure the cutting tools in the spindle. They are designed to accommodate different types of tools, such as end mills, drills, and taps.
6. Panneau de contrôle: The control panel includes a computer with CNC software that allows operators to program and control the machining operations. Operators input the toolpaths, cutting speeds, feed rates, and other parameters into the CNC system.
7. Système de refroidissement : A coolant system is used to lubricate and cool the cutting tools and workpiece during machining, which helps extend tool life and improve surface finish.
8. Chip Conveyor: As material is removed during machining, chips and debris are produced. A chip conveyor system removes these chips from the work area, ensuring a clean and safe machining environment.

Functions and Operations:

A machining center can perform various machining operations, including but not limited to:

1. Milling: This involves removing material from a workpiece by rotating a cutting tool (e.g., end mill) around its axis. Milling can create slots, pockets, contours, and complex 3D shapes.
2. Drilling: The machining center can drill holes of various sizes and depths into the workpiece.
3. Tapping: Threads can be cut into holes using specialized tapping tools.
4. Boring: Boring operations enlarge existing holes to precise dimensions.
5. Facing: The tool can be used to machine flat surfaces on the workpiece.
6. Contouring: Complex 3D shapes and contours can be machined with high precision.

Used VIGERT 855 Machining Centers are widely used in industries such as aerospace, automotive, medical device manufacturing, and general machining, where high precision, efficiency, and automation are crucial. CNC programming and operation are essential skills for working with machining centers, as they require the ability to create and edit programs and set up tooling correctly.
