The CNC Turning Process

In mechanical engineering, you cannot bypass the shaft to transfer power from the motor to the moving part. Of course, the shaft needs to rotate. But CNC turning and boring have many uses in various industries to produce parts that are usually axis symmetrical.

What is turning?

Turning is a subtractive machining process that uses cutting tools to remove material to create cylindrical parts. As the part rotates, the tool itself moves along the axis of the machined part, resulting in a helical tool path.

 

The term turning refers to the production of a part by performing a cutting operation on an external surface. The opposite of turning is boring, for example, lathes are used to create hollow parts.

 

Historically, this lathe was one of the first machines of its kind to produce parts in a semi-automated manner. Today, most companies offer CNC turning services. This means that the process is largely automated from start to finish.

 

CNC means Computer Numerical Control, which means that a computer system controls the machine. The input is a digital code. This controls all tool movements and rotation speeds as well as other supporting actions, such as the use of coolant.

 

The CNC Turning Process

What does the turning process actually involve? While the cutting itself is very simple, we will look at the entire sequence here, which actually starts with the creation of a CAD file.

The steps of the process are

● Create a digital representation of the part in CAD

● Creating the machining code from the CAD file

● CNC lathe setup

● Manufacturing of the turned part

Advantages and Applications of Rolling Machines

图片
Rolling machines , also known as roll forming machines, are a crucial component in the manufacturing and fabrication industries. These machines utilize a continuous bending process to shape metal sheets or strips into desired profiles. The process involves feeding the material through a series of rolls, which gradually shape it into the required form. Advantages of Using Rolling Machines Cost-Efficiency and Material Savings Rolling machines offer significant cost advantages over traditional fabrication methods. The continuous process reduces material wastage, leading to material savings. Moreover, the streamlined production process minimizes labor requirements, further reducing operational costs. Versatility in Material Selection One of the key advantages of rolling machines is their versatility in handling various materials. Whether you need to work with steel, aluminum, copper, or other alloys, a well-designed rolling machine can adapt to different material thicknesses and properties...

Introduction to Facing and Centering Machines: A Comprehensive Overview

图片
Facing and centering machines   are essential tools in the field of machining and manufacturing. They play a crucial role in achieving precise and accurate results by preparing workpieces for subsequent machining operations. This comprehensive overview will provide an introduction to facing and centering machines, including their functions, types, operation, and applications. Function of Facing and Centering Machines: Slanting Facing and centering machines  are primarily used to ensure the proper alignment and positioning of workpieces before machining. These machines perform two fundamental operations: Facing: The facing operation involves removing material from the surface of a workpiece to create a smooth, flat surface that is perpendicular to the rotational axis of the machine. This process helps achieve parallelism, flatness, and desired surface finishes. Centering: Centering refers to aligning the rotational axis of the workpiece with the spindle axis of the machine...
