MZG Deep Ditch End Milling Cutter System
The Deep Ditch End Milling Cutter is a specialized cutting tool engineered for efficient and precise machining of deep grooves, slots, and cavities. Characterized by its extended flute length and optimized helix angle and core design, these cutters overcome challenges associated with deep machining including chip accumulation, heat buildup, and deflection. Available in flat bottom and ball head configurations with uncoated and nano-coated variants for materials from aluminum to HRC60° hardened steel.
Deep Cutting Excellence
Specialized design for deep grooves, slots, and cavities with extended flute length and optimized helix angles for superior chip evacuation and stability.
Advanced Geometries
Available in flat bottom and ball head configurations with 2-flute and 4-flute options, uncoated and nano-coated variants for different material applications.
Precision Performance
Diameter range from Ø0.5mm to Ø4mm with deep ditch lengths up to 35mm, suitable for materials from aluminum to HRC60° hardened steel.
System Performance Analysis
The performance of a Deep Ditch End Milling Cutter is primarily driven by its ability to maintain cutting efficiency and dimensional accuracy in deep recesses. It exhibits excellent chip evacuation capabilities due to its optimized flute design, often featuring wider chip gullets and a specific helix angle that promotes upward chip flow. This minimizes chip re-cutting and packing, which are common issues in deep slotting and can lead to tool breakage or surface finish degradation.
These cutters are engineered for enhanced rigidity and stability, often employing a larger core diameter relative to their cutting diameter or through-tool coolant channels to withstand higher cutting forces and minimize deflection over extended reaches. The cutting edges are typically sharpened to maintain sharp cutting capabilities over long cutting depths, ensuring smooth, precise cuts and preventing excessive burr formation.
Many Deep Ditch End Milling Cutters incorporate advanced coatings like AlTiN (Aluminum Titanium Nitride) or TiAlN (Titanium Aluminum Nitride) which provide superior hardness, heat resistance, and lubricity, significantly extending tool life, especially when machining tough or abrasive materials. The deep ditch characteristic refers to their design with a long neck and extended flute length, allowing them to reach and mill deep features or slots in a workpiece.
Available in both flat bottom and ball head configurations, these tools feature tungsten steel construction with two cutting edges. Uncoated versions are designed for milling steel and nonferrous metal materials such as copper and aluminum, while nano-coated versions are specifically applied for milling HRC60° steel, cast iron, and stainless steel.
