CNC and conventional machining with process-specific grinding for new parts and dimensional restoration.
Technical detail
Core features
Separate stated milling156×108×84 in/44,000 lb and turning62 in diameter×156 in/14,000 lb options
Four- and five-axis milling and supplier-listed live tool changers; stated positioning accuracy of ±0.0002 in is distinct from finished-part tolerance.
Cylindrical grinding: 48 in swing × 144 in stroke; internal grinding: 48 in swing × 48 in stroke; vertical grinding: 48 in height × 55 in diameter; surface grinding: 16 in width × 60 in stroke.
Materials include titanium, stainless, nickel aluminium bronze, Inconel and tool steel
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Current commercial supplier service; Dartmouth Intertek management-system scope includes machining/grinding. Patent and unnamed valve case establish method and attributable example, not universal tolerance or naval acceptance.
Commercial availability
