GRINDING
SURFACE GRINDING
Delva provides precision surface grinding services for aerospace, defense, and medical components requiring tight dimensional control and superior surface finishes. We achieve flatness, parallelism, and perpendicularity tolerances in accordance with customer drawings and GD&T specifications, supporting requirements commonly held to ±0.0002” or better depending on geometry and material.
Our surface grinding capabilities support hardened steels, tool steels, stainless alloys, titanium, and specialty materials used in structural aerospace brackets, defense system components, and medical device tooling. Controlled material removal processes minimize thermal distortion and preserve metallurgical integrity. Surface finishes are achieved to specification, including fine micro-inch requirements critical for sealing surfaces, bearing interfaces, and precision mating components.
All grinding operations are performed with calibrated inspection equipment to verify flatness, thickness control, and surface quality, ensuring repeatability and compliance with high-reliability industry standards.
OD GRINDING
Delva performs precision OD grinding for cylindrical components requiring concentricity, roundness, and tight diameter tolerances. We support shafting, pins, bushings, and precision rotational components used in aerospace assemblies, defense mechanisms, and medical instruments.
OD grinding processes are controlled to maintain diameter tolerances commonly held to ±0.0001”–±0.0003”, with careful attention to cylindricity, concentricity, and surface finish requirements per engineering drawings. We routinely grind hardened and heat-treated materials while preserving dimensional stability and avoiding burn or micro-cracking.
Applications include precision alignment pins, actuator shafts, medical device drive components, and high-performance aerospace hardware where rotational accuracy and wear resistance are critical. All parts are inspected for dimensional compliance and surface integrity to ensure performance in high-load, high-vibration, or sterile operating environments.
