What is face turning?
In addition to CNC turning and milling, many operations can be done on CNC machines for different purposes. Today, we will learn about face turning, which is one of the machining methods, and how it is done.
What is face turning?
Face Turning; It is a machining operation that can be performed on a lathe or milling machine. Face turning, which ensures that the face of the workpiece to be machined is smooth and flat, can also be called transverse turning. In the face turning process, the excess piece at or around the material end is cut to give shape and size to the piece. During this process, either the workpiece or the cutting tool rotates to remove excess material.
Face Turning is the process of removing metal from the end of a workpiece to obtain a flat surface. Most of the time, the workpiece is cylindrical, but using a 4-bladed chuck it is possible to work with rectangular shapes to create cubes and other non-cylindrical shapes.
Face milling on a milling machine is primarily used for face milling. On the lathe, surface treatment is generally used in turning and drilling operations. Face turning is one of the main ways we can do it on a lathe when we want to give any shape to a particular part.
The function of facing on a lathe is mainly to reduce the length of the workpiece. In other words, it is to bring the workpiece to the desired size.
As Aktif Lazer, we use many different methods for your machining processes. The most commonly used metal removal method is face turning. You can also get detailed information by contacting us for your face-turning operations.
What is the turning process?
A certain sequence of operations should be followed while face turning. At this point, the following sequence should be followed for the face turning process;
- When the straight right side pen is selected, it must be connected inclined 10 degrees to the left.
- The speed of the lathe should be adjusted according to the cutting speed.
- The chip removal setting is given from the sport.
- Face turning should be done from the center of the workpiece to the edges.
Face turning from the center to the periphery is correct. At this stage, it will be WRONG if you operate from the outside to the center while facing. If you do it from the center outward, you are doing a RIGHT operation. In addition, if the lathe tool is connected with an angle of 10 degrees, it is TRUE, if it is not connected, it is WRONG.
After the workpiece is fixed on the CNC lathe and the face lathe tool is mounted on the tool holder of the lathe carriage, the workpiece must be cut vertically along the axis of rotation to cut the workpiece, while the tool rotates at the mouth of the chuck.
The first thing you need to do is to set up the lathe machine. Loosen the tool holder at this stage, open a tool about 10 to 15 degrees from the end of the workpiece to leave some clearance at the tip. We also need to center the tooltip vertically.
Factors Affecting the Quality of Face Turning
- The speed of the lathe and the progress of the process,
- dimensions and material of the cutting tool,
- types of material to be processed, and workpiece clamping method
will affect the quality and effectiveness of the face turning process on the lathe. Choose to rough or finish based on the materials that need to be removed. So every step should be done carefully while face turning. A skip should not be made during the face-turning process. The face turning process performed by following the rules is both very successful and very high quality and smooth-surfaced products are obtained.
The turning surface allows the workpiece (which is stationary) to rotate against the cutting tool. Several factors can affect the performance of lathe operations:
- The type of material from which the workpiece is made
- Size and material of the cutting tool
- Method of holding the workpiece
- rotational speed
When we talk about any face turning operation, especially on a lathe, we draw attention to the importance of “qualifying the surface”. In simple terms, qualifying the surface is the process of eliminating microscopic defects on the surface of the workpiece to make the surface as uniform as possible.
