A VMC, or vertical machining center, is a type of CNC (computer numerical control) milling machine that is commonly used in manufacturing. It is called a “vertical” machining center because the spindle that holds the cutting tool is oriented vertically, as opposed to the horizontal orientation of a CNC horizontal machining center.

A VMC typically consists of a bed or table that holds the work piece in place, and a spindle that rotates a cutting tool to remove material from the work piece. The spindle is mounted on a vertically oriented column, and the bed is mounted on a horizontal base. This configuration allows the cutting tool to move in three dimensions (X, Y, and Z) to create the desired shape of the work piece.

VMCs are widely used in a variety of industries, including aerospace, automotive, and medical, due to their versatility, precision, and efficiency. They are often used to create complex shapes and features on parts that require high levels of accuracy and repeatability.

It is capable of performing a wide range of machining operations, including:

Milling: This is the process of using a rotating cutting tool to remove material from the surface of a work piece to create a specific shape or feature.

Drilling: This is the process of using a cutting tool to create a hole in the work piece.

Reaming: This is the process of using a cutting tool to enlarge and smooth an existing hole in the work piece.

Tapping: This is the process of using a cutting tool to create threads on the inside of a hole in the work piece.

Boring: This is the process of using a cutting tool to enlarge an existing hole in the work piece.

Knurling: This is the process of creating a pattern of ridges on the surface of the work piece.

Parting: This is the process of using a cutting tool to separate the work piece into two pieces by cutting all the way through it.

Thread milling: This is the process of using a cutting tool to create threads on the surface of the work piece.
