Choosing the right corner radius end mill cutter can be a difficult task. Here, we’ll provide an overview of the types of cutters available, their purpose and applications, and tips on how to select the best one for your specific needs.
Choose the Correct Cutting Flutes.
The number of cutting flutes determines the efficiency and smoothness of the cutting process. A lower number of flutes means a slower cut but greater chip clearance, while a higher number allows for deeper and faster cuts in hard materials. When deciding on your corner radius end mill cutter, remember to choose one with good chip evacuation capacity and low vibration noise for maximum productivity and performance.
Select The Ideal Cutting Diameter.
The cutting diameter of the end mill needs to be appropriate for the material being cut. Too large a cutter will require more power in order to make cuts, while too small a cutter won’t have enough reach. To choose the ideal cutting diameter, consider the application and material type. For instance, larger cuts are suitable for harder materials that are difficult to penetrate with smaller diameters, while softer materials require smaller sizes in order to provide increased accuracy and precision.
Look at Shank and Helical Lengths Carefully.
Additionally, consider the shank and helical length when choosing an end mill cutter. The shank diameter should securely fit into the spindle of your machine, while the helical length of the cutting edge needs to be taken into consideration depending on how deep you want to make your cuts. A longer helix can reach deeper depths, so if you need more depth than usual in your cut, opt for a longer cutter than normal.
Know the Insert Compatibility Properties.
It’s important to know the insert compatibility properties of your end mill cutter. To ensure it will cope with the material you’re cutting, check the coating and geometry of the inserts. For example, AlTiN (aluminum titanium nitride) coated cutters are great for machining cast iron and stainless steel, while an uncoated cutter can be used on a wide range of materials such as plastics, aluminum, wood and copper.
Compare Between Utilization Coatings and Materials Used to Create the Cutters.
Before selecting an end mill cutter, you should understand how the utilization coating and material used in creating the cutters affect their performance. The correct combination can help increase accuracy and control tool wear. Depending on the application, consider coatings such as Carbide, AlCrN (aluminum chromium nitride), TiAlN (titanium aluminum nitride) and TiC (titanium carbide). These coatings are specifically designed for different material substrates to deliver maximum performance and precision. Additionally, explore materials like steel alloy or HSS that have unique characteristics suitable for certain tasks such as drilling large blind holes.
