CAPABILITIES

Machined in-house. Qualified before it ships.

01

5-Axis Precision Machining

Simultaneous 5-axis CNC on forged blanks, held to ±0.02mm on bearing bore concentricity.

02

Forged Alloy Construction

42CrMo4 and Ti-6Al-4V forgings, sourced and traced from mill certificate to finished part.

03

Fatigue & Load Qualification

Every lever geometry cycles through shot-peened fatigue testing before design release.

04

Surface & Corrosion Treatment

Class 3 hardcoat anodize and cadmium-free corrosion protection for marine and desert theaters.
