The characteristics of CNC turning shaft parts:
High precision: It can achieve high dimensional and positional accuracy, ensuring the smoothness of shaft rotation and transmission accuracy.
Good surface quality: makes the shaft fit more tightly with other parts, reducing wear.
Key points of processing technology:
Clamping method: Select an appropriate clamping method based on the length and diameter of the shaft, such as a three jaw chuck, tip, etc., to prevent deformation of the shaft during processing.
Tool selection: Hard alloy tools are usually used, and for shaft materials with higher hardness, ceramic tools may be chosen.
Cutting parameters: Reasonably set cutting speed, feed rate, and cutting depth to improve machining efficiency and quality.
Quality inspection:
Dimensional inspection: Use measuring tools such as calipers, micrometers, etc. to measure the diameter, length, and other dimensions of the shaft.
Geometric tolerance detection: The roundness, cylindricity, coaxiality, and other geometric tolerances of the shaft are detected through equipment such as a coordinate measuring instrument.
The automation level of CNC Turning is reflected in the following aspects:
Programming control: CNC machine tools execute machining tasks through programming. Once the program is input into the control system of the machine tool, the machine tool can automatically perform machining without the need for manual intervention.
Precision control: The CNC control system can precisely control the feed rate, cutting depth, rotation speed and other parameters of cutting tools, thereby ensuring machining accuracy and surface quality.
Good repeatability: Due to the high precision of CNC control systems, CNC Turning can achieve high repeatability. This means that once the program is validated and optimized, it is easy to replicate the same machining results, ensuring that each workpiece meets quality requirements.
Reducing human errors: Due to the high automation of CNC Turning, the likelihood of human intervention and errors is reduced. This helps to improve processing efficiency and product quality.
Strong adaptability: CNC machine tools can adapt to different processing needs. By modifying the program, it is easy to adjust machining parameters and tool paths to adapt to workpieces of different shapes and sizes.
