Carbide Ball Nose End Mills for Steel Machining

Product Detail

PEX Series 2-Flute Ball End Mill – Born for Precision Curved Surface and Contour Machining

2-Flute High-Efficiency Chip Evacuation Design · High-Finish Ball Profile · Suitable for Curved Surface Machining of Non-Ferrous Metals and Steel Parts

Core Positioning: The Precision Choice for Curved Surface Machining

In mold cavity machining, electrode manufacturing, and precision part contour milling, the quality of the curved surface directly determines the workload of subsequent processes and the performance of the final product. The PEX Series 2-Flute Ball End Mill, featuring an ultra-fine grain carbide substrate and precision ball nose profile grinding technology, is specifically designed for machining scenarios that demand exceptional surface finish and dimensional accuracy. Whether it's complex curved surfaces in aluminum alloys or small-radius contours in steel parts, the PEX 2-flute ball end mill delivers "mirror-finish" machining results with its sharp cutting performance and excellent stability.

Product Features

PEX Series Core Advantages: Precisely Solving Machining Pain Points

• Precision Ball Profile for Accurate Forming

  
  

Pain Point: Errors in the ball profile lead to curved surface distortion, increasing the difficulty of subsequent polishing.

Solution: High-precision optical grinding technology is adopted to strictly control the ball profile accuracy and runout tolerance. This ensures that every tool can accurately replicate the programmed path when machining 3D surfaces, reducing manual rework and improving mold assembly precision.

• 2-Flute Large Chip Pocket Design for Worry-Free Chip Evacuation

  
  

Pain Point: During curved surface machining, chip clogging can easily scratch the machined surface, affecting surface quality.

Solution: The 2-flute structure provides spacious chip pockets. Combined with an optimized helix angle and polished flutes, it ensures chips are evacuated quickly and smoothly, preventing surface damage caused by recutting. It is particularly suitable for curved surface machining in deep cavities or narrow slot areas.

• Sharp Cutting Edges with Strong Support: Combining Strength and Flexibility

  
  

Pain Point: Small-diameter ball end mills often lack rigidity, making them prone to chatter or breakage during machining.

Solution: While maintaining an extremely sharp cutting edge to reduce cutting resistance and achieve better surface quality, the overall tool rigidity is enhanced through a reinforced core diameter design. This enables it to withstand the impact of radial cutting forces, remaining stable even when machining hard materials, and effectively suppressing chatter marks.

• Diverse Coating Options for Different Materials

  
  

Pain Point: steel parts have vastly different requirements for tool coatings, making it difficult for a single coating to meet both needs.

Solution: Coated with AlTiN/AlCrN (Aluminum Titanium Nitride / Aluminum Chromium Nitride) multi-layer composite coating, offering high red hardness and oxidation resistance. This significantly enhances heat resistance and tool life.
