End Mill Tools

What is an end mill tool? In the metal processing industry, an end mill is a milling cutter that mills. This is a cutting tool used in industrial cutting. It differs from drilling tools in corresponding applications, geometry, and production.

The drill can only be cut in the axial direction, while mills’ cutting can usually cut in all directions, though some cannot cut axially. End mills are used in profile milling, tracer milling, face milling, and many other milling applications.

 

Classifications

There are many kinds of machining tasks such as grooves, slots, and pockets in the workpiece and the mills may be processed from a variety of tool bits for cutting. Common types of cutter heads are square end cutters, ball end cutters, T-slot cutters, and shell mills.

Besides, the square end cutter mills square slots, pockets, and edges. Ball end mills can mill radius slots or fillets. T-slot milling cutter mills T-slots. Shell end mills are used for large flat surfaces and angle mills. These tool types are also different.

Each cutting tool has four critical angles, including the end cutting edge angle, axial relief angle, radial relief angle, and radial rake angle. Depending on the material to be milled and the milling task to be performed, different tool styles and methods can be used for mills.

For example, when milling materials like aluminum, it may be advantageous to use tools with very deep, polished flutes, which is a very sharp cutting edge and high rake angles in the aspect of mills.

Other Variables

When the cutter mills hard materials, such as stainless steel, the shallow grooves, and square-cut edges will optimize material removal rates and prolong the tool lifespan. Various materials are used to produce cutting tools.

Carbide inserts are the most common style because they are suitable for efficient mills. When special tool shapes are needed, high-speed steel is usually used, and it is not usually used in high-speed production processes.

Materials such as ceramic blades and end mills are commonly used mills for high-speed machining. Diamond inserts are usually used for products that require tight tolerances and are usually composed of high surface quality (non-ferrous or non-metallic materials).

In the early 1990s, the use of coatings to reduce wear and friction (among others) became more common in conventional mills and other functional mills.

 

Installation and Application

End mill cutters are usually installed on a milling machine or machining center for general end milling tasks. On the milling machine, whether it is a manual type or a programming model, you can precisely control the process on the end mill task. The machining center can also be equipped with an end mill, and the purpose is to perform the latter process after completing the main machining process.

Therefore, the machining center is more convenient nowadays for the manufacturer to conduct the manufacturing process related to the end mill machining. For this reason, the installed tool magazine usually has the ability to accommodate more tools to complete multiple tasks.

 

Why Machining Centers

The machining center is a highly developed machine tool that can handle multiple milling tasks at once. Initially, the machining center evolved from the milling machine in the 1960s. Since then, the development of this specific type of machine has made good progress in the industry.

The machine tool center has been widely used in various industries and worked hard for the industry. Milling is a process that uses a rotating tool to remove material by advancing the tool into one or more workpieces. This processing method can be done in different directions.

In addition to turning, milling also involves a variety of operations, ranging from a single tiny part to large and heavy milling tasks. Similar to turning, milling is one of the most commonly used machining methods to provide precise tolerances.
