Tips for Choosing the Best Mill Cutting Tooling

There are a few things that you need to keep in mind when selecting the right milling cutter for your project. Here are some tips that can help you:

Milling Cutter Size and Diameter

The size of the milling cutting tools is determined by the milling depth and width. An increase in width and depth before mill tooling signifies an increase in the size of the milling cutter. However, the usual index milling cutter diameter range is 16–630 mm.

It is advised to use milling cutters with smaller diameters when machining objects with a lot of surface area. Ideally, 70% of the cutter's cutting blades should be actively engaged during any milling process.

The diameter of the spindle on the machine tool is another element that might affect the milling cutter's diameter. D = 1.5d, where d is the spindle diameter, is the suggested formula for choosing a face milling tool diameter.

Additionally, while cutting holes, the tool size must be carefully considered because if the milling cutter diameter is too big or too tiny for the hole, it could harm the workpiece or the tool.

Powerful Milling Cutter

Cutting power and workpiece processing size are the two main elements to take into account when choosing the best milling cutter. For instance, when choosing the diameter of a face mill cutting tool, the tool's power needs should fall within the milling machine cutting tool's power range.

Additionally, the machine's maximum revolution matching the minimum tool cutting speed (60 m/min) should be the primary consideration for a small-diameter end mill.

Optional Milling Tool Body Selection

The tool's tooth count should be taken into account while selecting a milling tool. With a 100-mm diameter, a dense-tooth milling tool can have 8 teeth, whereas a coarse-tooth tool can only have 6 teeth. Due to their broad chip flute, which lessens friction between the workpiece, cutter body, and chips themselves, coarse metal milling tools are perfect for rough machining.

Furthermore, it's crucial to remember that at the same feed rate, the cutting load per tooth of a milling tool with dense teeth is lower than that of a milling tool with coarse teeth.

Blade Selection for Milling Tools

The most effective choice for fine milling tools is to use a grinding blade. Better surface roughness and machining accuracy are made possible by this type of insert's improved dimensional precision and increased cutting-edge positioning accuracy. However, since a pressed blade can reduce processing costs, it is preferable to use one for roughing.

Furthermore, using carbide inserts without sharp rake angles would reduce the tool's service life, especially with small cutting depths and feeds.
