What is Tool Steel CNC Machining?

Tool steel CNC machining focuses on high-carbon and alloy steels engineered for wear resistance, hardness, and toughness. Typical grades include O1/A2/D2 for cold work, H13 for hot work, S7 for shock resistance, and P20 for mold bases.

Tooling: Fine-grain carbide, tough coatings (TiAlN/TiCN) to handle abrasion and heat.
Coolant: Flood or high-pressure coolant; through-tool preferred for deep features.
Feeds/Speeds: Maintain chip load—avoid rubbing to limit work-hardening and edge chipping.
Rigidity: Rigid fixturing + short stick-out = better surface and dimensional control.

Precision Tool Steel CNC Machining

3, 4, 5-Axis CNC Milling

Multi-axis machining for complex cavities, ribs, and hard-milling. Rigid setups, balanced holders, and coated carbide deliver clean walls and consistent geometry in both annealed and hardened tool steels.

CNC Turning & Mill-Turn

From punches and sleeves to core pins and shafts, combined turning + milling in one setup improves concentricity, finish, and lead time—ideal for prototype to production.
