Why Choose AXALLOY for D2 CNC Machining?

D2 tool steel is renowned for its exceptional wear resistance, high hardness, and toughness—making it ideal for dies, punches, and wear parts. However, these same properties make it notoriously difficult to machine, especially post-heat treatment.

At AXALLOY, we don't just cut metal; we specialize in difficult-to-machine alloys. We evaluate material behavior, geometry, tolerances, and surface requirements before a single chip is made. Whether your D2 parts require heavy pre-machining or ultra-precise post-hardening finishing, we provide a stable, controlled production route.

Our Approach to D2 Tool Steel

  • Rigid Machining

    Utilizing high-torque 3, 4, and 5-axis CNC milling centers to efficiently rough and finish annealed D2.

  • Hard Machining & Grinding

    Precision surface and cylindrical grinding (down to ±0.002 mm) to achieve critical dimensions after heat treatment.

  • Precision EDM

    Wire and Sinker EDM for intricate features, sharp internal corners, and narrow slots on hardened D2 components.

  • Full Process Management

    We manage the entire value chain, including heat treatment, deburring, and final inspection.

Technical Capabilities for D2 Components

We are equipped to handle the most demanding technical profiles, including thin walls, critical interfaces, and tight geometric tolerances.

CNC Milling & Turning

  • Equipment: 3, 4, and 5-axis CNC milling; Mill-Turn centers with live tooling.
  • Tolerances: Precision dimensional tolerances down to ±0.005 mm.
  • Capabilities: Complex contours, pockets, off-center machining, and precision threading (down to M1.0).

Wire & Sinker EDM

Ideal for Hardened D2

  • Wire EDM: Cutting accuracy down to ±0.005 mm, minimum cutting width of 0.15 mm. Perfect for punches, dies, and precision inserts.
  • Sinker EDM: Surface finish down to Ra 0.4 μm, minimum internal corner radius of R0.05 mm. Ideal for deep cavities and complex internal profiles.

Precision Grinding

  • Types: Surface, cylindrical, and centerless grinding.
  • Tolerances: Grinding tolerance down to ±0.002 mm, flatness to 0.003 mm.
  • Surface Finish: Down to Ra 0.2 μm for critical sealing or bearing surfaces.

Built for Engineering, Procurement, and Quality Teams

We partner with OEMs, Tier 1/Tier 2 suppliers, and engineering firms in Aerospace, Medical Devices, Semiconductor Equipment, Robotics, and Industrial Automation across North America, Europe, and advanced Asian markets.

We know you aren't just looking for the lowest unit price—you need manufacturability, process control, and dependable communication.

For Engineering

  • DFM Support

    Comprehensive drawing review, tolerance analysis, and manufacturing-process development before production begins.
