What is the CNC turning?
"CNC turning is based on the technical requirements of parts and its processing, to create the machining program, and input the machining program into the NUMERICAL control device,through numerical control device control the movement of machine tool spindle and feed, change cutters, and workpiece clamping and releasing, Make tool parts and other auxiliary devices work in strict accordance with the specified sequence of trajectories and parameters, to get parts machined and meet the drawing requirement"
The advantages
- Rapid prototype producing
- High-accuracy and small tolerance
- Stable processing quality
- Cost effective and efficient when small and medium-volume runs
How CNC Turning works?
Turning the rotary body surface, can use the forming tool method or tool tip trace method. When turning, the workpiece is driven by the spindle of the machine tool. A tool clamped on a tool rest for feeding motion. The cutting speed v is the linear speed (m/min) at the contact point between the rotating workpiece surface and the turning tool; The cutting depth is the vertical distance (mm) between the workpiece surface to be machined and the machined surface at each cutting stroke, but the contact length (mm) between the tool and the workpiece perpendicular to the feed direction when cutting and forming turning.
Features of CNC Turning
1. It is easy to ensure the position accuracy of each machining surface of the workpiece.
2. The cutting process is relatively stable, avoiding inertia force and impact force, allowing the use of large cutting parameters, high-speed cutting, which is conducive to the improvement of productivity.
3. Suitable for finish machining of non-ferrous metal parts.
Advantages
1.High turning efficiency.
2.The cost of equipment input is low. At the same time of productivity, the investment of lathe is obviously better than that of grinder, and the cost of its auxiliary system is also low.
3.Suitable for small batch production.
4.Hard turning can make parts obtain good overall machining accuracy.
