hollow end mill
Proficiently crafted from metal, hollow end mills are a type of milling cutter, created to cut a vast array of materials including wood, plastic, and even composite matter. These versatile cutting tools are often known as shell end mills and are utilized on a milling machine for a diversity of milling operations.

A plethora of different sizes and styles of hollow end mills can be found on the market. One of the most widespread types is the mill with either two or four flutes - sharp cutting edges which can either feature a straight or a spiral shape. The choice between these two patterns is dictated by the material that needs to be worked on - harder materials are best cut with spiral blades, whereas soft ones call for straight ones.

End mills come in a variety of finishes, including uncoated, Titanium Nitride (TiN), and Titanium Aluminum Nitride (TiAlN). While the uncoated option is the least costly, it is also the least durable. TiN and TiAlN are more expensive but offer superior sharpness retention, as well as enhanced resistance to wear and tear.

Before selecting a hollow end mill, attention should be paid to the mill size and shape that suit the material to be milled as well as the desired finish. Using a 2-flute type would be suitable for softer substances while harder materials are commonly processed with a 4-flute model. Additionally, coatings are another essential factor that should not be ignored.

Once the appropriate end mill is identified, the procedure to properly load it into the milling machine can begin. To begin, keyless chucks is placed within the chuck, then tightened. After this, the end mill can be moved and placed above the material which is meant to be cut.

As the end mill powers through the material, a trio of vital variables - cutting speed, feed rate, and depth of cut - are all taken into consideration on the milling machine. The former is determined by the rate at which the end mill spins, while the latter adjusts the rate at which it moves through the material. Ultimately, the last factor - depth of cut - decides how far into the material this tool will delve.

Once the necessary specifications have been finalised, the milling machine is fired up and the end mill is gently inserted into the material. Progressively, the end mill will meander through the materials repeatedly until it creates a cut of the desired depth.

After the cutting is done, the end mill is hoisted and the material is taken away. Subsequently, it can be conveyed to its next location and the method can be iterated until every necessary cut has been done.
