CNC Turning Metal Parts

CNC turning, also known as CNC lathing, is a machining process used to produce cylindrical parts from a workpiece. It is commonly used for creating metal parts with high precision and accuracy. In CNC turning, a computer-controlled machine tool, known as a lathe, rotates the workpiece while a cutting tool removes material to create the desired shape.

 

CNC turning is a versatile and efficient process for manufacturing metal parts with high precision and repeatability. CNC turning metal parts are essential components of various machinery, equipment, and devices. It is widely used in various industries, including automotive, aerospace, electronics, and machinery manufacturing. They require high precision and accuracy in their production to ensure the smooth functioning of the end-product. Dongguan Henghui Hardware Co., Ltd which specializes in the research, development, production, and sales of CNC turning parts.

What is turning process?

When begining to make a CNC turning metal parts, we need to do these things.

 

1. Design: Begin by creating a design for the metal part using computer-aided design (CAD) software. The design will include the dimensions, shape, and features of the part. In general, our customers provide the design, and we will checking it beofre machining. Or we could help our customer to draw the drawings.

 

2. Material selection: Choose the appropriate metal material for your part based on its mechanical properties, such as strength, durability, and heat resistance. In general, we will bought the material according to our customers requirement.

 

3. Workpiece preparation: Prepare the metal workpiece by cutting it into a suitable size and shape. The workpiece is typically a cylindrical rod or bar.

 

4. Workholding: Secure the workpiece in the lathe using a chuck or collet. This ensures stability during the machining process.

 

5. CNC programming: Use CNC software to program the lathe with the required tool paths, speeds, feeds, and other machining parameters. The program controls the movement and actions of the lathe during the machining process.

 

6. Tool selection: Choose the appropriate cutting tools based on the material and design requirements. Different tools may be needed for roughing, finishing, threading, or other specific operations.

 

7. Machining operation: Start the CNC turning process by running the programmed instructions. The lathe rotates the workpiece at high speed while the cutting tool removes material to shape the part. The tool may move along the X, Y, and Z axes to achieve the desired dimensions and features.

 

8. Inspection: Regularly inspect the machined part during the process to ensure it meets the required specifications. Use measuring tools, such as calipers or micrometers, to verify dimensions and tolerances.

 

9. Finishing operations: After the main turning process, additional operations like threading, grooving, or chamfering may be performed to complete the part.

 

10.Quality control: Once the part is finished, conduct a final inspection to ensure it meets all quality requirements. This may involve using various measurement techniques and inspection equipment.

 

All of our CNC metal parts are strictly executed according to the process, so that the quality of the product can be guaranteed

What are the types of turning?

There are several types of turning operations commonly used in CNC turning. Such as:

 

1. : Facing is the process of removing material from the end face of a workpiece to create a flat surface that is perpendicular to the rotational axis of the lathe.

 

2. External Turning: In external turning, the cutting tool removes material from the outer diameter of the workpiece. It is used to create cylindrical shapes, reduce the diameter, or create grooves and threads on the external surface.

 

3. Internal Turning: Internal turning, also known as boring, involves removing material from the inside diameter of a workpiece. It is commonly used to create holes, cylinders, and other internal features.

 

3. Taper Turning: Taper turning is the process of gradually reducing or increasing the diameter of a cylindrical workpiece along its length. This is achieved by adjusting the position of the cutting tool relative to the workpiece.

 

4. Contour Turning: Contour turning involves machining complex shapes and contours on the external or internal surfaces of a workpiece. It requires precise tool movement and often involves the use of specialized tooling or programming techniques.

 

5. Thread Turning: Thread turning is the process of cutting threads on the external or internal surface of a workpiece. It is commonly used to create screw threads for fasteners or threaded holes for mating parts.

 

6 Grooving: Grooving is the process of creating narrow, linear recesses or grooves on the surface of a workpiece. These grooves can serve various purposes, such as accommodating O-rings, creating snap-fit features, or improving aesthetics.

 

7. Parting: Parting, also known as cut-off, is the process of cutting a workpiece to separate it into two or more parts. It involves using a special cutting tool to make a deep, straight cut through the workpiece.

 

There are so many kinds of lathe processing parts, we can have general lathe processing, precision automatic lathe, centering machine, and so on various lathes, we can make various requirements of lathe parts to meet the production needs of customers. Depending on the complexity of the part and the desired features, multiple turning operations may be combined to create the final shape and dimensions of a metal part.

 

What are the benefits of CNC turning?

CNC turning provides numerous advantages. It enables precise and consistent machining, enhances efficiency through automation, accommodates various part designs with versatility, saves time and cost, and facilitates the production of complex parts with exceptional accuracy. These advantages make CNC turning a preferred method for manufacturing metal parts in terms of quality, productivity, and cost-effectiveness.

 

What is the accuracy of CNC turning?

The accuracy of CNC turning depends on various factors such as machine capability, tooling, programming, and part complexity. However, CNC turning can achieve high levels of accuracy. Typically, it can achieve tolerances within a few thousandths of an inch (0.0254 mm) or even tighter, depending on the specific requirements and capabilities of the machine and tools used. This level of accuracy allows for precise and consistent machining, ensuring that the final parts meet the desired specifications. We could provide the CNC turning parts tolerance with +/-0.0001mm.
