What is CNC turning in parts manufacturing?
1、Introduction
1 、Explanation of CNC turning
CNC turning, which stands for “computer numerical control,” is a way to make cylindrical parts that are very precise and accurate. In CNC turning, a computer-controlled machine tool turns a workpiece while a cutting tool removes material from the workpiece to make the desired shape.
2、Importance of CNC turning in parts manufacturing
CNC turning is an important part of making parts because it makes it possible to make complicated parts that are accurate and consistent. It is used to make parts for a wide range of applications in industries like aerospace, automotive, medical, and more.
2、What is CNC turning?
1、Definition of CNC turning
CNC turning is a way of making things that uses a machine tool that is controlled by a computer to remove material from a rotating workpiece to make it into a certain shape.
The cutting movement is made by turning the part to be made, which is held in place by a chuck or clamp. The feed movement is made by moving the tool that does the cutting. When these two movements are put together, chips of material can be taken away. You can also change how fast these movements happen to get the results you want.
Mechanical turning is a great way to make parts out of many different materials, like steel, aluminum, copper, zinc, wood, and plastic, to name a few.
Mechanical turning is also often used as a secondary machining process to add or change features on parts that have already been made using another machining process. Turning is a great way to add precise rotational characteristics to a part that already has its basic shape. This is because it can provide high tolerances and smooth surfaces.
2、Equipment needed for mechanical turning
For mechanical turning, you need a workpiece, a fixture, and a cutting tool. You also need a mechanical lathe or turning machine.
The workpiece is a piece of material that has already been shaped. It is attached to the fixture, which is attached to the lathe, and can spin very quickly. Most of the time, the cutting tool is a single-point metal cutting tool made of high-speed steel (HSS) or carbide that is also fixed in the machine. In some cases, however, multi-point tools are used.
3、Comparison between CNC turning and traditional turning
Traditional turning is done with hand-held or semi-automated machine tools, but CNC turning is done with a machine tool that is controlled by a computer. Compared to traditional turning, CNC turning can be done with more precision, accuracy, and consistency.
During the mechanical turning process, the part can go through a number of steps to get the shape that is needed. These tasks can be categorized as either internal or external. The outside diameter of a part is changed by external operations, while the inside diameter is changed by internal operations.
3、How CNC turning works？
1、Overview of CNC turning process
The CNC turning process involves the following steps:
A、Design the part using CAD/CAM software
B、Program the CNC machine using the design specifications
C、Set up the machine and workpiece
D、Run the CNC machine to remove material from the workpiece and create the desired shape
2、Key components of a CNC turning machine
A CNC turning machine is made up of four main parts: a spindle, chuck, cutting tool, and tool turret.
3、Programming a CNC turning machine
To program a CNC turning machine, CAD/CAM software is used to create a digital design of the part, which is then turned into code that the machine can understand.
4、External turning operations
Shooting
A single-point cutting tool moves along the workpiece in an axial direction, removing material to make notches, tapers, chamfers, and contours, among other things. Most of the time, these parts are machined with a shallow radial depth of cut and several passes until the diameter is right.
Dressage
A single-point cutting tool moves radially along the end of the part, removing a thin layer of material to make a flat, smooth surface. The depth of the face, which is usually very small, can be cut in a single pass or by making several passes with a smaller axial depth of cut.
Grooving
A single-point cutting tool moves along the side of the workpiece in a radial direction, cutting a groove the same width as the tool. You can make multiple cuts to make a groove wider than the width of the tool, and you can use tools with different shapes to make grooves with different shapes.
Cutting
A single-point cutting tool moves along the side of the workpiece in a radial direction until it reaches the center or inside diameter of the workpiece. This lets a part of the workpiece be broken off or cut off. room.
The thread
A single-point cutting tool moves axially along the side of the workpiece, cutting threads in the outer surface. The cutting angle is usually 60 degrees. Threads can be cut to a certain length and distance apart, and they may need to beInternal turning operations
Drilling
A drill goes into a piece of work from the end and cuts a hole the same size as itself.
Boring
A cutting tool goes into the part axially and cuts the material along an internal surface to make notches, tapers, chamfers, and contours, among other things.
The boring tool is usually a single-point cutting tool with a boring head that can be changed to cut the diameter you want. Most of the time, reaming is done after drilling a hole to make the diameter bigger or get more accurate measurements.
Tapping
A cutting tool goes into the part from the end and cuts internal threads in a hole that is already there.
4、Advantages of CNC turning
1、Higher precision and accuracy
CNC turning is more precise and accurate than traditional turning, so it can make parts that are exactly what the customer wants.
2、Increased production efficiency
CNC turning is a very efficient method that makes it possible to make parts faster than with traditional turning.
3、Reduced labor costs
CNC turning requires less manual labor, resulting in reduced labor costs and increased productivity.
5、Applications of CNC turning
1、Examples of industries that use CNC turning
CNC turning is used in many different fields, such as aerospace, automotive, medicine, and more.
2、Types of parts that can be manufactured using CNC turning
CNC turning can be used to make shafts, bushings, bearings, and many other parts.
6、Conclusion
1、Recap of key points
CNC turning is a very accurate and efficient way to make cylindrical parts that fit together well and are always the same size. It is used in many different industries and can make a wide range of parts.
2、Future prospects of CNC turning in parts manufacturing
As technology keeps getting better, CNC turning is likely to be used to make even more parts. This will make it possible to make even more complex and precise parts.
