What Is CNC Turning?

CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a cutting tool is fed to the piece to remove material to create the desired shape. This process is typically used to create round or tubular shapes， Қосымша, CNC turning allows the generation of complex external geometries and internal holes, including the machining of various threads、hexagons.

CNC Turning Process Overview

1. Workpiece Preparation

Материалдық таңдау: The process begins with choosing an appropriate material for the workpiece, which could be metal, пластмасса, орман, or other materials.

Clamping: The workpiece is clamped into the chuck of the CNC lathe. The chuck holds the workpiece securely and rotates it during the machining process.

2. Бағдарламалау

CAD/CAM Software: Engineers use Computer-Aided Design (Ата-тор) software to create a detailed model of the part to be produced. This model is then imported into Computer-Aided Manufacturing (Камер) software to generate the machining instructions.

G-код: The CAM software translates the design into G-code, a language CNC machines understand. This code contains all the instructions for tool movements, spindle speeds, Беру бағалары, and other parameters.

3. Құрылғыны орнату

Құралды таңдау: The appropriate cutting tools are selected and loaded into the turret of the CNC lathe. Common tools include turning tools, boring bars, and threading tools.

Tool Calibration: Each tool is calibrated to ensure it is correctly positioned relative to the workpiece. This involves setting the tool offsets and ensuring the machine’s coordinate system is properly aligned.

4. Өңдеу процесі

Spindle Rotation: The CNC lathe’s spindle rotates the workpiece at a predetermined speed. The speed is selected based on the material and the desired surface finish.

Tool Movement: Holding the cutting tools, the turret moves along the X and Z axes (and sometimes the Y axis) to engage the tools with the rotating workpiece. The CNC system precisely controls the movement.

Материалды жою: The cutting tool removes material from the workpiece in a controlled manner.

5. Сапаны бақылау

In-Process Inspection: As the machining progresses, measurements are taken to ensure the part meets the specified dimensions and tolerances. This can involve manual measurements or automated probing systems.

Final Inspection: Once the machining is complete, the part is removed from the machine and undergoes a thorough inspection for dimensional accuracy, Бетті аяқтау, and other quality criteria.

6. Post-Processing

Deburring and Finishing: The machined part is often subjected to additional processes such as deburring (removing sharp edges), жылтырату, or coating to achieve the desired final properties.

Жиналыс: If the part is a component of a larger assembly, it may be assembled with other parts as required.

3. Drilling: Creating holes along the rotational axis of the part. Advanced centers can drill in various orientations.
4. Boring: Enlarging an existing hole by feeding a cutting tool into the hole’s inner wall.
5. Threading: Cutting threads on the inner or outer diameter of the workpiece.
6. Grooving/Parting: Creating features like O-ring grooves or separating the finished part from the stock using a grooving tool.
7. Тоқырау: Producing a diamond pattern on the outer diameter by compressing the material, commonly used for adding grips.
