The quality of a machined part is highly dependent on the type of turning insert used during production. Therefore, proper turning insert selection is essential in order to maximize tool life and get the desired results. This article will discuss the factors to consider when selecting a turning insert for a particular machining operation, and how to increase tool life using the correct insert.
The first factor to consider when selecting a turning insert is the material that is being machined. Different materials require different types of inserts in order to achieve optimal results. For example, harder materials require a tougher and more resilient insert, while softer materials require a more delicate insert. Additionally, it is important to select an insert with the correct geometry for the material being machined.
Another factor to consider when selecting an insert is the cutting speed. If the cutting speed is too high, the insert can become damaged due to excessive heat. Therefore, it is important to select an insert with the correct grade and geometry for the cutting speed. Additionally, selecting an insert with the correct geometry for the machining operation can help to minimize vibration, which can also lead to tool failure.
Finally, the type of coolant used can also affect tool life. Using a coolant with the correct lubricity can help to reduce heat, and also help to reduce wear on the insert. Additionally, selecting an insert with the correct geometry can help to minimize the amount of friction between the insert and the workpiece, which can also help to increase tool life.
In conclusion, selecting the proper turning insert is essential for maximizing tool life and getting the desired results. Factors such as the material being machined, cutting speed, and type of coolant should all be taken into consideration when selecting an insert. Additionally, selecting an insert with the correct geometry for the machining operation can help to reduce vibration and minimize friction, which can help to extend tool life.
