Milling is the manufacturing of metal products using inserts to remove material from a workpiece. The variety of shapes and sizes determines the cutting or removal of these materials from the object. This is why the quality of inserts are as important to the machinery as well as the workpiece.
Most beautifully finished metal products that are available for everyday use or production have been smoothed or finished by a metal milling insert. Milling inserts are replaceable bits that are used to machine tough some of the toughest materials. Some of the materials that they shape or cut are steel, stainless steel, cast iron, non-ferrous materials, Titanium, hardened steel, and plastic.
These inserts are generally made of carbide, which allows them to be durable at extremely high temperatures and during high-speed applications for tasks such as drilling, hole making, finishing, etc.
Once limited to basic shapes, optimizations by manufacturers now allow for a wide variety of milling insert geometric styles that are referred to as elliptical, frustum and helical. Each shape is specific in size, figure, and tolerance determined by the temperatures, elements, and manufacturing task that are required of it.
Some features that will be important to consider when purchasing inserts are:
- Teeth, which actually cuts the material
- Flutes, which are the grooves between the teeth
- Coating, which impacts the cutting process and tool life
What are the benefits of inserts?
There is a monumental amount of force placed on a milling insert while it’s at work. This use of an insert will:
- Ensure safe and precise machining
- Provide high metal removal rates in challenging conditions
- Increase tool life
- Provide reliable performance in dry and wet machining
