10mm 4-Flute TiSiN Solid Carbide Ball Nose End Millfor HRC55 3D Contouring & Mould Work

The 4-flute TiSiN ball nose end mill is engineered for finishing passes and semi-finish Z-level contouring in steel and stainless steel up to HRC55. More cutting edges reduce per-tooth chip load, enabling higher feed rates while maintaining lower surface scallop height (Ra). TiSiN coating withstands the elevated temperatures of continuous 3D contouring on hardened mould surfaces without edge chipping.

R5mm TiSiN 4F — Recommended Applications

  • Large mould cavity semi-finish and finish passes
  • Automotive stamping die contouring
  • Compound curve aerospace structural parts
  • Forging die cavity profiling
Machining Tip: At R5mm, balance step-over and feed rate to manage thermal load in HRC55 hardened steel. Recommended: 8–15% D1 step-over for semi-finish, 3–8% for finishing. Use trochoidal Z-level strategy to maintain constant chip load on curved surfaces.

Scallop Height vs Step-Over — R5mm

Residual scallop height (cusps) between adjacent tool paths, calculated for R5mm ball nose:

Step-OverStep-Over mmScallop Height (µm)Typical Ra (µm)
2% D10.201.00.20
5% D10.506.31.25
8% D10.8016.03.21
10% D11.0025.15.01
15% D11.5056.611.31
20% D12.00101.020.20

h = R − √(R² − (ae/2)²). Actual Ra depends on feed rate, chip load, and material.

TiSiN — Why It Works for Ball-End Machining

  • TiSiN hardness > 3,500 HV — superior to TiAlN on ball-end profiles
  • Low friction reduces heat at ball-tip during 3D contouring
  • Suitable for dry, MQL, or flood coolant environments
  • 4-flute: lower scallop height per pass for finishing operations
