What Are the Best Practices for Maintaining and Caring for Aluminum Milling Inserts

Deep hole drilling inserts have become an essential part of the machining industry as they are used for cutting holes that are longer than 20 times their diameter. As such, it is important to ensure that the right coolant pressure is used for these inserts to ensure their optimal performance.

The recommended coolant pressure for deep hole drilling inserts depends on the material being machined and the tungsten carbide inserts type of insert being used. In general, the recommended coolant pressure should be between 50 to 70 bar for all types of inserts and materials. This is because higher coolant pressures result in increased cutting force, which in turn increases tool wear.

It is also important to note that the optimum coolant pressure is also influenced by the cutting speed. Generally, the higher the cutting speed, the higher the coolant pressure should be. For example, when machining aluminum, the coolant pressure should be around 60 bar, whereas when machining stainless steel, it should be around 70 bar.

In addition, it is important to ensure that the coolant pressure is maintained properly during operation. This is because fluctuating pressures can cause the insert to vibrate, resulting in poor surface finish and increased tool wear. As RCMX Insert such, it is important to use a pressure regulator or flow meter to ensure that the correct coolant pressure is maintained throughout the machining operation.

Overall, the correct coolant pressure is an important factor for achieving optimal performance from deep hole drilling inserts. The recommended coolant pressure should be between 50 to 70 bar, depending on the material being machined and the type of insert being used. It is also important to ensure that the coolant pressure is maintained properly during operation.
