Long Neck Carbide Ball Nose End Mills for Steel Machining
Product Detail
PEX Series Long Flute Ball End Mill – The Extending Hand for Deep Cavity Curved Surfaces, Engineered for Extreme Depth-to-Diameter Ratio Contour Machining
Long Flute Ball Nose Design · Reinforced Core · Mirror Finish Polishing · Specifically Built for Deep Cavity Curved Surfaces, Deep Slot Contours, and High Side Wall 3D Machining
Core Positioning: The Choice for Rigidity and Precision in Deep Cavity Curved Surface Machining
In mold deep cavity core, deep slot contour, and high side wall 3D curved surface machining, excessive tool overhang, insufficient rigidity, difficulty maintaining ball nose profile accuracy, and poor chip evacuation are the four major challenges restricting machining quality and efficiency. The PEX Series Long Flute Ball End Mill, featuring an ultra-fine grain carbide substrate and optimized long-flute ball nose geometry, is specifically designed for demanding scenarios that pursue large depth-to-diameter ratio curved surface machining and ball nose profile accuracy. While maintaining sharp ball nose cutting edges, it achieves the perfect combination of rigidity and precision in deep cavity curved surface machining through a reinforced core design, precision ball nose grinding, and polished flutes. It is the ideal tool for deep cavity core curved surfaces and deep slot contour 3D machining.
Product Features
PEX Series Core Advantages: Precisely Solving Machining Pain Points
Long Flute Ball Nose Design for Extended Curved Surface Machining Depth
Pain Point: Standard ball end mills have insufficient flute length, making it impossible to complete deep cavity curved surface machining in one pass, requiring multiple step-downs or extended tool holders, which affects surface continuity and profile accuracy.
Solution: A long flute ball nose ratio design is adopted, with flute lengths reaching 3-5 times the diameter or even higher. While ensuring tool rigidity, it maximizes cutting depth, enabling one-pass forming of deep cavity curved surfaces and deep slot contours, avoiding step marks, and improving surface continuity and processing efficiency.
Precision Ball Nose Profile for Ensuring 3D Accuracy
Pain Point: In deep cavity machining, the ball nose profile is prone to wear or deformation, leading to 3D curved surface distortion and increasing the difficulty of subsequent polishing.
Solution: High-precision optical grinding technology is adopted to strictly control the ball nose profile accuracy and runout tolerance. This ensures that every tool can accurately replicate the programmed path when machining deep cavity 3D curved surfaces, reducing manual rework and improving mold assembly precision.
Reinforced Core Structure for Resisting Radial Deflection
Pain Point: Long flute ball nose tools have excessive overhang, making them prone to deflection during cutting, leading to curved surface profile errors or chatter marks.
Solution: A significantly reinforced core diameter design greatly enhances the tool's bending rigidity. Even under deep cavity side milling and large radial cutting forces, it effectively suppresses tool deflection, ensuring curved surface profile accuracy and surface finish.
Polished Chip Flutes and Diverse Coatings for Smooth Chip Evacuation and Multi-Material Adaptability
Pain Point: In deep cavity curved surface machining, chips have a long evacuation path and are prone to clogging, scratching the machined surface; different materials have varying requirements for coatings.
Solution: Deeply optimized chip flutes with mirror-like polishing treatment greatly reduce the friction coefficient between chips and the flute surface, ensuring smooth chip evacuation from deep cavity areas & Coated with AlTiN/AlCrN (Aluminum Titanium Nitride / Aluminum Chromium Nitride) multi-layer composite coating , offering high red hardness and oxidation resistance to enhance heat resistance and tool life.
