Developed for American customers · serial volumes 15,000–35,000 units / year per component
Landing-Gear Barrel
Precision-machined main structural component of an aircraft landing-gear assembly, developed for HAL — machined, measured and delivered to aerospace tolerances. Explore the actual component in 3D below.
CUSTOMER // HAL · AEROSPACE
PROCESS // PRECISION CNC MACHINING
A single machined component that carries the aircraft's landing loads: deep concentric bores, thin-wall webs, pocketed gussets and cross-tube interfaces — every datum referenced to aerospace tolerances, machined from solid alloy with zero appetite for error.
Dimensionally cleared on our Mitutoyo CMM and delivered to Hindustan Aeronautics Limited — the development that anchors BDS Defence inside India's aerospace manufacturing ecosystem, with serial production capability standing ready.
Digital Validation
CAM programming & toolpath simulation in Siemens NX / SolidCAM before a single cut.
Multi-Setup CNC
Precision machining across multiple setups on our high-accuracy vertical machining centres.
CMM Verification
Full dimensional report on the CRYSTA-Apex V — every critical feature measured and traceable.
Delivered to HAL
Inspection-cleared, protected and documented — ready for landing-gear assembly integration.
Mission-Critical
The barrel is the primary load-bearing member of the landing-gear assembly — machined from solid to aerospace tolerances.
Complex 5-Sided Machining
Deep bores, thin-wall webs, pocketed gussets and cross-tube interfaces — validated on our Mitutoyo CMM.
Gateway Programme
A milestone development that anchors BDS Defence inside India's aerospace manufacturing ecosystem.
