Milling Cutters

Material characteristics dictate the ideal tool geometry:

1. For Aluminum & Non-Ferrous Metals: We recommend 2 or 3-flute end mills with high helix angles ( typically 45° to 55° ) and polished flutes. This wide-groove design ensures maximum chip evacuation space and prevents the material from welding to the cutting edges.
2. For Stainless Steel & Exotic Alloys: We recommend 4 to 7-flute end mills with variable pitch and unequal helix designs. This structure minimizes harmonic vibration (chatter), increases tool rigidity, and distributes the heavy cutting load across multiple edges to maximize tool life.

Achieving high MRR while maintaining surface finish requires balancing your cutting parameters with tool design. JIAYI SEIKO's high-performance end mills utilize specialized core diameters to increase rigidity against deflection. For optimized results:

1. Deploy Trochoidal Milling (High-Efficiency Milling - HEM) strategies,

utilizing a smaller radial depth of cut ( ae ) and full axial depth of cut (ap).

1. Use tools engineered with variable helix geometries, which constantly disrupt harmonic patterns to eliminate chatter even under aggressive feed rates.

We engineer specific coating solutions based on the abrasive nature of the workpiece:

1. For Hardened Steels (up to 65 HRC): We utilize advanced AlTiN or nACo (nanocomposite) coatings. These coatings exhibit exceptional hot-hardness and oxidation resistance, thriving in high-temperature, dry-machining conditions.
2. For Carbon Fiber (CFRP) & Abrasive Composites: Standard coatings wear out almost instantly. JIAYI SEIKO provides CVD Diamond-coated routers and end mills, offering extreme micro-hardness to prevent abrasive flank wear and ensure clean, delamination-free edges.
