Precision OD Grinding & Tolerance Calibration of Heavy-Duty D2 & DC53 Steel Ironworker Dies

Publish Time: 2026-07-13     Origin: Site

Watch the 20-second cylindrical outer diameter (OD) grinding process for ALAS ironworker tooling, ensuring perfect concentricity for high-frequency metal punching applications.

⚙️ Cylindrical OD Grinding & Strict Metrology:

Precision outer diameter grinding ensures a perfect slip-fit matching alignment with the hydraulic ironworker machine's die base. This eliminates offset tool wear and stabilizes the structural cold forming performance at a premium 58–62 HRC hardness range.

Strict Micrometer Tolerance Calibration

Every single production batch of our heavy-duty round ironworker punch and die sets is rigorously inspected using external micrometers, maintaining a strict dimensional tolerance within -0.01 mm to -0.03 mm to prevent eccentric failures.
