CNC turning is a type of machining process in which CNC lathes are used to produce parts. In this process, the work piece is rotated on a rotating axis (spindle) and a cutting tool is used to remove the material from the piece. Unlike the milling machine where the tool rotates, in cnc turning it is the work piece that rotates to create the desired shape on the piece.
Benefits and Characteristics of CNC turning:
2. Speed and efficiency: cnc lathe can quickly produce complex parts due to high automation.
3. Ability to produce complex parts: Thanks to programming and precise control, it is possible to produce complex parts with special shapes with cnc lathe.
4. Reduction of human error: Because of the automation of processes, errors caused by human performance are minimized.
CNC Lash Applications:
CNC lathes have different types, each of which is designed for specific applications and production of parts with different characteristics. In the following, we mention some types of cnc lathes and the characteristics of each one:
1. Double -axis CNC
This type of lathe is the most common and simplest type of cnc lathe, which has two movement axes (z and x). In this machine, the work piece rotates to two z axes and the cutting tool moves along the x axis to remove the material from the piece. Application: Suitable for producing simple parts such as Shafts, bushings and screws.
Features: Simple control, high precision and suitable speed for producing parts with cylindrical forms.
2. Multi -axial CNC lathe
These types of cnc lathes use three or more axes (usually x,y,z and even c and b axes).
These axes allow the cutting tool to move in different directions and create more complex parts. Additional axes such as the y-axis for transverse movement and the c-axis for rotating the part around the vertical axis are used. Application: Production of complex parts with three-dimensional shapes. such as molds and precision machined parts.
Features High precision and complexity, suitable for parts that require several machining steps
3. CNC Live with Live Axis (Live Tooling)
In this type of lathe, in addition to the rotation axes of the part, the cutting tools are also able to rotate. This feature allows the lathe to simultaneously use rotating tools (such as drill and milling) for different operations such as drilling and milling.
Application: Suitable for producing parts that They require several machining operations (such as turning and milling in one machine).
Features: Reduction of production time due to the combination of several operations in one process.
4. CNC CNC multiple spindle
In this type of lathe, there are two or more spindles to rotate the workpiece. These devices work on two or more parts at the same time, which increases the production speed.
Application: Suitable for mass production of similar parts, such as automotive and electronic parts.
Features: Increased productivity and reduced machining time due to the use of multiple spindles
5. Swiss CNC Type (Swiss Type)
Swiss lathe is specially designed for very small and precise parts. In this type of lathe, the work piece is rotated axially in the spindle and the cutting tool is placed very close to the piece in order to provide higher accuracy. Application: Suitable for the production of parts. Small and precise such as medical, watchmaking and electronic parts.
Features: Very high precision, suitable for mass production of parts with small diameter and long length.
6. Vertical CNC (Vertical Turning LATH-VTL)
In the vertical cnc lathe, the spindle axis is vertical and the workpiece is installed vertically on the machine. This type of lathe is suitable for large and heavy parts.
Application: Suitable for producing large and heavy parts such as brake discs and large wheels.
Features : Ability to machine parts with large and heavy dimensions which is not possible horizontally.
7. CNC Cnc (Mill-Turn)
These devices are a combination of milling and cnc turning.
In this type of devices, turning and milling capabilities can be used simultaneously These lathes usually have additional axes for complex operations.
Application: Suitable for the production of complex parts requiring several operations, such as aerospace parts and complex equipment. b> Features: Multitasking, reducing the need to move the workpiece between different devices and increasing accuracy.
