Every material provides its own set of machining challenges. With non-ferrous materials such as aluminum, brass, or plastic, the soft and gummy nature of the material can cause issues with chip packing, short tool life, inconsistence performance, and variations in surface finish. To achieve optimum performance, MITGI recommends considering custom tools that are designed for the material and application. We work with customers every day who look for ways to improve tool performance, extend tool life, and improve product outcomes.
How does this play out?
Application: COMPANY A is an aerospace manufacturer. As the company prepares to scale up for full production on a new line, the team is challenged by edge build-up they are currently experiencing when profiling. MITGI developed a custom tool to help the team achieve their goals in time to meet the production schedule.
Material: Aluminum
Tool type: Ball end mill
Coating: NACRO

Add-on request: While COMPANY A does see some improvement in the built-up edge, they would like to improve it further. With long cycle times, even a small improvement can provide significant cost improvements over the life of the product.
MITGI recommendation: Pre- and Post-coating flute polishing to help reduce heat and maintain cutting edge for longer periods of time. Flute polishing reduces friction, and in this application, allows the chip to form, making evacuation easier with less resistance.
Application: COMPANY B is running a contouring op where a radius is needed at the bottom of a wall. COMPANY B is tasked with reducing cycle times whenever possible; they want to remove chips quickly and efficiently to achieve a smooth finish and extend tool life. MITGI designed a ball end mill with a long length of cut to accomplish the task.
