How to choose the best milling cutter?

There are a few considerations to make while choosing the best milling cutter for your project. Here are some pointers to get you started:

Milling Cutter Size and Diameter

The size of the mill cutting tools is determined by the milling depth and width. An increase in width and depth before mill tooling implies an increase in milling cutter size. However, the usual index milling cutter diameter range is 16630mm.

When cutting objects with a large surface area, smaller diameter milling cutters are recommended. Ideally, 70% of the cutter's cutting blades should be engaged in cutting throughout any milling process.

The diameter of the machine tool spindle is another component that might influence the milling cutter diameter. The recommended diameter for a face milling tool is D = 1.5d, where d is the spindle diameter.

When milling holes, the size of the tool must also be carefully considered because if the milling cutter diameter is too large or too tiny in comparison to the hole, it may cause damage to the workpiece or tool.

Power of a Milling Cutter

The most important elements to consider when choosing the correct milling cutter are cutting power and workpiece processing size. For example, when choosing the diameter of a face mill cutting tool, the power demand of the tool should be within the milling machine cutting tool's power range.

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

Selection of Milling Tool Body

The number of teeth on a milling tool is an important consideration when selecting one. A dense-tooth milling tool with a diameter of 100mm can contain 8 teeth, but a coarse-tooth tool with the same diameter has only 6 teeth. since their broad chip flute, coarse metal milling tools are good for rough machining since they reduce friction between the workpiece, cutter body, and the chip itself.

Furthermore, for an equal feed rate, the cutting load per tooth of a dense-toothed milling tool is less than that of a coarse-toothed milling tool.

Selection of Milling Tool Blade

For fine milling tooling, the best alternative is to use a grinding blade. This sort of insert improves dimensional precision while boosting cutting-edge placement accuracy during milling, allowing for superior surface roughness and machining accuracy. However, it is better to use a pressed blade for roughing because it reduces processing costs.

Furthermore, employing carbide inserts without acute rake angles will diminish tool service life, especially when working with short-cutting depths and feeds.
