WORKING PRINCIPLE, ADVANTAGES AND APPLICATIONS

1. What is CNC Turning?

CNC turning is a precision machining method that utilizes Computer Numerical Control (CNC) technology. In this process, the workpiece (usually metal, plastic, wood, or other solid materials) is fixed on the chuck of the CNC lathe and rotates with the rotation of the spindle. At the same time, the cutting tool controlled by the CNC system moves linearly along one or more axes to cut material from the rotating workpiece.

2. The main features and advantages of CNC turning include:

High Precision and Consistency

Through preset computer program control, it can ensure that each processed part has a high degree of dimensional and shape consistency.
 

Flexibility

Easy to modify machining programs, adaptable to different part designs, suitable for small to large batch production.
 

Automation

Reduces manual intervention, improves production efficiency, and reduces the labor intensity of operators.
 

Strong Material Adaptability

Suitable for processing various materials, including hard alloys, stainless steel, engineering plastics, etc.

COMMON PROBLEMS IN CNC TURNING

  • Q How can we ensure surface quality in CNC turning technology?

    A
    Choose appropriate cutting parameters
    Cutting speed: Choose the appropriate cutting speed based on the hardness of the material and the material of the tool. Excessive or insufficient cutting speed can affect the surface quality.
    Feed rate: Appropriate feed rate can reduce surface roughness, and excessive feed rate can lead to surface scratches.
    Cutting depth: Smaller depth of cut helps to get better surface finish.

    Use high-quality cutting tools
    Tool material: Choose high-quality tool materials such as hard alloy, ceramic, or cubic boron nitride (CBN), which can maintain sharpness and are not easily worn.
    Tool geometry: Adopt appropriate geometric parameters such as rake angle, rake angle, and blade inclination angle to reduce cutting force and improve surface quality.

    Ensure the stability of workpieces and cutting tools
    Workpiece clamping: Use appropriate clamping methods to ensure that the workpiece does not vibrate during the machining process.
    Tool clamping: Ensure that the tool is firmly clamped on the tool holder to reduce tool vibration.

    Use measuring tools
    Surface Roughness Test: Use a surface roughness tester to monitor and adjust surface quality.
    Online detection system: Use advanced on-line inspection system to monitor the surface quality in real time during the machining process.

  • Q What parts can be machined by CNC turning?

    A CNC turning produces cylindrical and axisymmetric parts. This process is commonly used to manufacture items such as shafts, pins, rods, bushings, and pulleys. It is also very suitable for manufacturing complex contours on external threads, internal holes, and even cylindrical surfaces. The precision of CNC turning can achieve strict tolerances and smooth surfaces, making it very suitable for parts that require precise fitting and motion, commonly found in automobiles, aerospace, and manufacturing machinery.
