CNC Turning / CNC Lathe
CNC turning is a manufacturing process in which a computer numerical control (CNC) machine is used to produce cylindrical parts. The process involves using a lathe or turning machine, which is a machine tool that rotates a work piece on its axis while a cutting tool is used to remove material to create the desired shape.
In CNC turning, the cutting tool is mounted on a tool holder that is attached to a turret or tool post. The turret or tool post is mounted on a slide, which moves the tool in and out of the work piece as it rotates. The movement of the tool is controlled by a computer program, which allows for precise and consistent cuts to be made.
CNC turning is a highly efficient and accurate method of producing cylindrical parts. It allows for the production of complex shapes and geometries with a high degree of precision, and is widely used in a variety of industries, including aerospace, automotive, and medical device manufacturing.
There are several types of operations that can be performed on a CNC lathe, including:
Turning: This is the process of rotating the work piece and using a cutting tool to remove material from the surface to create a cylindrical shape.
Facing: This is the process of using a cutting tool to remove material from the end of the work piece to create a flat surface.
Chamfering: This is the process of using a cutting tool to create an angled edge on the work piece.
Threading: This is the process of using a cutting tool to create threads 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.
Drilling: This is the process of using a cutting tool to create a hole in the work piece.
CNC Milling / Vertical machining Center (VMC)
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.
