How to Machine Parts

Last Updated on October 13, 2023 by assistant

Precision machining plays a vital role in manufacturing, enabling the production of high-quality parts with tight tolerances and complex designs. In this blog, we will explore the precision machining processes commonly used today, providing valuable insights and examples to help you understand the various technologies involved.

CNC turning

CNC turning is a widely used machining process that involves rotating a workpiece while using cutting tools to remove material to form a cylindrical shape. This process is commonly used to make shafts, bolts, and other round parts. At Ruitai Platform, we most commonly use turning technology, but it is not limited to the following two types:
1. Cylindrical turning: In cylindrical turning, the cutting tool removes material from the outer diameter of the workpiece. This process is used to create precise cylindrical shapes and achieve dimensional accuracy.


2. Internal hole turning: The focus of internal hole turning is to remove the material inside the workpiece. It is often used to create holes, grooves, or precise internal features.


CNC milling

CNC milling is another versatile machining process used to remove material from a workpiece using rotating tools. It can produce a variety of shapes, including grooves, pockets, and complex contours. Some of our common milling techniques include:

Face Milling: Face milling involves cutting material from the surface of a workpiece to create a flat surface. The technology is used to produce engine blocks, molds and other large components.


Perimeter Milling: In perimeter milling, the cutting tool removes material from the perimeter of the workpiece to obtain a smooth and precise outer contour. It is often used to create complex contours or achieve a high surface finish.



Drilling is a machining process that involves using a rotating cutting tool to create a hole in a workpiece. This is a basic operation in many industries. Commonly seen in sheet metal processing, the following are two commonly used drilling techniques:
Twist drill: Twist drill is the most common method for processing round holes. It involves rotating a drill bit and applying axial force to penetrate the workpiece. The technology is widely used in the aerospace, automotive, and construction sectors.


Gun Drilling: Gun drilling is used to machine deep straight holes with a high aspect ratio. It is often used to make injectors, oil passages, cooling channels, etc.



Grinding is a precision machining process that typically uses a grinding wheel to remove material and achieve high surface finish and dimensional accuracy. It is often used for finishing operations or to create complex shapes. In grinding technology, we most often use the following two examples:

Surface Grinding: Surface grinding is used to obtain a smooth and flat surface finish on the workpiece. It is often used to create precise mating surfaces, such as sealing surfaces or bearing seats.


Cylindrical Grinding: Cylindrical grinding is used to produce cylindrical shapes with tight tolerances. It is widely used in the production of rotating parts such as shafts and pistons.



Precision machining processes are essential to obtain high-quality parts with tight tolerances and complex geometries. The techniques mentioned in this blog, including turning, milling, drilling, and grinding, represent only a small part of the vast array of precision machining methods available today.
