Micro End Mills are precision cutting tools made of high-strength carbide alloy, designed for machining brass and gold. These miniature end mills are available in a range of cutting diameters from 0.2mm to 0.9mm, with 2 teeth on each end. Our 1/4" solid micro carbide 4 flute carbide end mill, mini flat end mill, and other micro end mill products are perfect for precise and efficient cutting operations. With superior cutting edge strength and durability, our micro end mills provide consistent and reliable performance even in the toughest of environments.
Using carbide micro diameter end mills offers several advantages compared to other types of end mills.
Precision and Accuracy: Carbide micro diameter end mills are specifically designed for high-precision machining applications. Their small diameter allows for intricate and detailed cuts, providing excellent precision and accuracy in producing fine features and tight tolerances.
Rigidity: Carbide is a rigid and durable material, which translates into reduced tool deflection during machining. This rigidity helps maintain dimensional accuracy and improves surface finish, especially when working with delicate or thin-walled workpieces.
Wear Resistance: Carbide end mills possess exceptional wear resistance due to the hardness of the tungsten carbide particles in the composite material. This wear resistance allows the end mills to maintain their cutting edge sharpness and performance over extended periods of use, resulting in longer tool life.
Heat Resistance: Carbide micro diameter end mills exhibit excellent heat resistance, enabling them to withstand high cutting speeds and temperatures generated during machining. This characteristic is crucial for achieving efficient material removal rates and preventing premature tool failure due to thermal damage.
Versatility: Carbide micro diameter end mills are versatile tools suitable for a wide range of materials, including metals, plastics, composites, and even some ceramics. They can effectively machine different materials with varying hardness levels, making them suitable for a broad spectrum of machining applications.
High-Speed Machining Capability: The combination of rigidity, wear resistance, and heat resistance of carbide micro diameter end mills enables them to handle high-speed machining operations. This capability helps improve productivity by reducing machining time while maintaining precision and surface finish.
Reduced Machining Forces: Due to their small size, micro diameter end mills generate lower cutting forces compared to larger end mills. This characteristic minimizes the stress on the workpiece and machine tool, reducing the risk of part deformation and improving overall machining stability.
It's important to note that while carbide micro diameter end mills offer numerous advantages, they are best suited for specific applications that require fine details and tight tolerances. For general-purpose machining or roughing operations, larger diameter end mills or different tool types may be more appropriate.
When using carbide micro diameter end mills it is essential to adjust cutting parameters to optimize machining performance for different materials. Here are some key cutting parameters to consider when machining specific materials.
Feed Rate: Generally, a higher feed rate can be used for softer metals like aluminum, while a lower feed rate is suitable for harder metals like stainless steel or titanium. Spindle Speed: Higher spindle speeds are typically employed for softer metals to increase material removal rates, while lower spindle speeds may be used for harder metals to reduce tool wear and heat generation. Depth of Cut: The depth of cut depends on the specific application and the stability of the machining setup. It is important to balance material removal rates with tool life and avoid excessive cutting forces.
Feed Rate: Plastics can be machined at relatively higher feed rates compared to metals. However, the feed rate should be adjusted based on the specific plastic material and its characteristics, such as hardness and heat sensitivity. Spindle Speed: Spindle speeds for machining plastics are typically moderate to high to prevent melting or excessive heat buildup. It is important to avoid excessive heat that can lead to material deformation or poor surface finish. Depth of Cut: Similar to metals, the depth of cut in plastics should be chosen carefully to balance material removal rates and prevent excessive cutting forces that might cause workpiece deformation or tool breakage.
Feed Rate: Composites like CFRP and FRP have unique machining properties. A lower feed rate is often recommended to prevent delamination or fiber pull-out during machining. Spindle Speed: Moderate to high spindle speeds are generally used for composites to maintain cutting efficiency and prevent excessive heat buildup. Depth of Cut: Composites are often machined with shallow depths of cut to minimize the risk of delamination and fiber damage. Multiple passes with increasing depth may be employed for roughing operations.
Feed Rate: Ceramics require lower feed rates compared to metals or plastics due to their high hardness and brittleness. Slow and controlled feed rates are necessary to prevent tool fracture and chipping. Spindle Speed: Moderate spindle speeds are typically used for ceramic machining. Excessive speeds can lead to tool wear or thermal damage, while too low speeds might result in poor surface finish. Depth of Cut: Ceramics are typically machined with shallow depths of cut due to their hardness. Multiple passes and proper cooling or lubrication methods are employed to dissipate heat generated during machining.
These parameters serve as general guidelines, and it's important to consider the specific material properties, machine capabilities, and desired machining outcomes. It's recommended to start with conservative cutting parameters and make adjustments based on the actual cutting performance and results achieved.
Carbide micro diameter end mills are capable of effectively machining a variety of materials. Depending on the job, different metals, plastics, composites, ceramics, and printed circuit boards (PCBs) may be machined. When using carbide micro end mills, it's important to consider the specific properties of each material and adjust cutting parameters accordingly.
Metals: Carbide micro diameter end mills can be used for machining various metals, such as aluminum, stainless steel, tool steel, brass, copper, and titanium. These end mills are well-suited for creating intricate features and precise cuts on hard metals.
Plastics: End mills with small diameters can be used to machine plastics, including acrylic, polycarbonate, PVC, nylon, and ABS. The sharp cutting edges of carbide micro diameter end mills help create clean cuts and smooth finishes in plastic components.
Composites: Carbide micro diameter end mills can be employed when machining composite materials, such as carbon fiber reinforced polymers (CFRP) and fiberglass reinforced polymers (FRP). Composites are often used in aerospace, automotive, and sporting goods industries.
Ceramics: Machining ceramics can be a difficult task, due to their hardness and brittleness. However, carbide micro diameter end mills may be used when machining certain ceramics, such as alumina and zirconia. Machining ceramics requires special care in terms of tool selection, cutting parameters, and coolant/lubrication methods.
PCBs: Carbide micro diameter end mills are often used when machining printed circuit boards (PCBs). These end mills can accurately produce traces, drill holes, and create fine features on the PCB surface.
Different coatings or geometries can be applied to the end mills to further enhance performance and improve tool life when working with certain materials.
