The CNMG120404-HF NH205 is a high-precision turning insert specifically designed for aluminum machining, including alloys with high silicon content. Aluminum and its alloys have unique machining properties, and this insert is engineered to address them. Its ultra-sharp edge and optimized chip control system enable burr-free, high-speed cutting, which is essential for achieving the high-quality surface finishes demanded in many aluminum applications. It is a preferred choice for manufacturers seeking precision and efficiency in aluminum machining.
CNMG120404-HF Geometry: The 80° diamond shape, paired with a 0.4 mm corner radius and the specialized NH205 chipbreaker, is designed to ensure smooth chip evacuation even at high speeds. This geometry minimizes chip clogging, which can lead to poor surface finish and tool damage.
Uncoated Carbide: The insert features a polished, uncoated surface that reduces friction between the tool and the aluminum workpiece. This property is critical for preventing aluminum adhesion, which can mar the surface finish. The uncoated design also contributes to achieving mirror-like finishes on aluminum components.
High-Speed Capability: Capable of operating at 200–300 m/min cutting speeds and 0.1–0.3 mm/rev feed rates, this insert is ideal for CNC lathes with high spindle power. Its high-speed performance allows for increased productivity in aluminum machining operations .
Precision Grinding: Undergoes precision grinding processes to achieve tolerances of ±0.01 mm. This level of precision ensures consistent dimensional accuracy across long production runs, which is vital for maintaining interchangeability of components.
Industry: Widely used in aerospace, automotive, and electronics industries. These sectors rely heavily on aluminum components due to their lightweight and high strength-to-weight ratio, and require precise machining.
Operations: Specialized in finishing of aluminum components such as engine parts, heat sinks, and precision housings. The insert's ability to produce high-quality surface finishes makes it suitable for these critical components.
Machining Scenarios: Recommended for dry machining to avoid coolant-related surface defects. Aluminum is prone to staining and other surface issues when exposed to certain coolants, so dry machining with this insert helps maintain the integrity of the workpiece surface.
Q: How is the NH205 chipbreaker optimized for aluminum?
A: Its concave design is specifically engineered to promote the formation of short, curly chips. This chip shape prevents tangling around the tool or workpiece and avoids surface scratches, ensuring a smooth machining process.
Q: What is the maximum hardness of aluminum alloys it can handle?
A: It performs best in aluminum alloys with a hardness up to 150 HB, such as 6061-T6 and 7075-T6. These alloys are commonly used in various industries, and the insert is well-suited to meet their machining requirements .
