High-Precision SKD11 Tool Steel Machining Services
Achieve uncompromising dimensional accuracy and exceptional wear resistance with our custom SKD11 precision machining solutions. As an ISO 9001:2015 certified manufacturer specializing in heavy-duty tooling steel, we engineer complex components that withstand severe abrasive wear, extreme mechanical stress, and high-impact industrial operations.
SKD11 (JIS grade high-carbon, high-chromium cold-work die steel, equivalent to AISI D2) is notoriously challenging to cut due to its high alloy content and tendency to work-harden. Our facility utilizes advanced 5-axis CNC milling, Swiss turning, slow-wire EDM, and precision surface grinding to process SKD11 in both annealed and vacuum heat-treated states (achieving stable hardness up to 58–62 HRC). By controlling thermal expansion and stress release during cutting, we consistently maintain micro-level tolerances within $\pm 0.005\text{ mm}$.
Manufacturing Capabilities & Engineering Advantages
Tight Tolerances: Precision grinding and wire-cut EDM achieving linear accuracy down to $\pm 0.002\text{ mm}$.
Advanced Heat Treatment Control: In-house vacuum hardening and cryogenic treatment to eliminate residual stress, preventing micro-cracking and post-machining distortion.
Surface Integrity: Fine finishing techniques reaching $Ra\ 0.2\ \mu\text{m}$, dramatically extending tool die lifespan.
Comprehensive Quality Assurance: 100% CMM (Coordinate Measuring Machine) inspection, optical profiling, and material certification (MTR) provided with every shipment.
Primary Industrial Applications
Our machined SKD11 components serve critical roles across high-wear environments:
Stamping & Blanking Dies: High-durability punches, matrix inserts, and slitting cutters.
Automotive Tooling: Form rolls, draw dies, and heavy-duty wear plates.
Recycling & Plastics Equipment: Industrial shredder blades, pelletizing knives, and granulator components.
Precision Gauges: Custom plug gauges, master ring gauges, and high-hardness fixtures.

Frequently Asked Questions (FAQ)
Q: What is the optimal machining sequence for hard SKD11 parts?
A: We perform heavy roughing and feature creation in the annealed state ($\sim 200\text{ HB}$), leave precise finishing allowances, execute vacuum heat treatment to target HRC, and finish-machine via hard milling, jig grinding, or EDM to prevent warping.
Q: Can you provide full material traceability for international shipments?
A: Yes. Every batch includes chemical composition reports, heat treatment hardness logs, and full CMM dimensional inspection sheets tailored for global procurement standards.
