DLC coated HM end mills for aluminium

DLC (Diamond-Like Carbon) coated carbide end mills are an excellent choice for machining aluminum on CNC machines. DLC coating combines properties of diamond with those of carbon, offering a number of benefits that significantly improve the performance of carbide (HM) tools.

Here are some of the main features of these end mills:

Advantages of DLC-coated end mills for aluminum processing

Friction Reduction: The DLC coating significantly reduces friction between the tool and the machined material. This is especially useful in aluminum, which tends to tools sticking.
Increased tool life: Thanks to the increased wear resistance and hardness of the DLC coating, tools last longer, reducing the need for frequent replacement.
Improved surface finish: Reduced friction and reduced sticking tendency of aluminum ensure a smoother, high-quality surface finish.
High wear resistance: DLC offers superior protection against abrasion and erosion, extending tool life even under severe cutting conditions.
Reduced chip buildup: Due to its smooth surface and low affinity for aluminum, DLC helps reduce chip buildup on the tool, improving the efficiency of the cutting process.

Characteristics of DLC coated carbide end mills

Carbide composition: this end mills are made of carbide, a material composed of tungsten carbide and metal binders, which offers high hardness and wear resistance.
DLC Coating: Diamond-Like Carbon (DLC) DLC coating is known for its extreme hardness, low coefficient of friction and high wear resistance.
Tool geometry: this end miils are designed with specific geometries for aluminum, with optimal rake angles and flutes designed for rapid chip evacuation.

Applications of DLC coated carbide end mills

Automotive industry: For the machining of aluminum components such as engine blocks, cylinder heads, and structural parts.
Aerospace Industry: For the production of lightweight and strong aluminum components, essential for reducing the weight of aircraft.
Consumer electronics: For the production of aluminum cases and components for electronic devices.
Precision mechanics: For the production of precision mechanical parts in aluminium, where the quality of the surface finish is crucial.
