Precision CNC Machining Services
JADE-CNC provides precision CNC machining service for precision machined parts, precision components, and custom precision components that require tight tolerance machining, practical process planning, and inspection support. We manufacture metal and plastic parts from customer drawings, including complex milled parts, turned parts, large components, prototypes, and low-volume production parts for global projects.
Precision CNC Machining for Critical Features
Precision CNC machining is the convergence of state-of-the-art
machinery, controlled processes, and expert execution to achieve near-
perfect part geometry. It is the enabling technology behind modern
medical devices, aerospace innovation, and scientific instrumentation.
Precision CNC machining is used when a part has critical dimensions, tight-fit areas, datum references, threads, bores, flatness, concentricity, or surface finish requirements that affect assembly and function.
Advantages Of Precision CNC Machining
Tight Tolerance
Machining tolerance as tight as +/- 0.005 in (0.127 mm)
Complex Shape
Machine complicated parts and features.
Consistent Production
Automated process ensures consistent quality across high volume production.
Quality Standards
Machined parts adhere to highest quality standards (ISO 2768, ISO 9001 and AS9100).
Precision Machining Capability Review
Precision machining depends on controlled setup, suitable material, clear tolerance priorities, stable tooling, and inspection planning. JADE-CNC focuses on the features that affect assembly, function, and repeatability instead of treating every dimension as equally critical.
Drawing-Based Tolerance Review
Critical dimensions, datum references, thread notes, hole positions, flatness, and mating surfaces are reviewed before machining.
Stable Setup Planning
Workholding, tool access, part rigidity, setup direction, and deformation risk are checked before production planning.
Complex Feature Machining
Milled features, turned features, cross holes, pockets, threads, slots, and multi-side features are reviewed according to part geometry.
Inspection and Documentation
Dimensional reports, CMM checks, gauge checks, visual inspection, and customer-required records are confirmed when needed.
Multi-Axis and Large Part Precision Machining
For rapid prototyping and high precision machining, JADE-CNC owns multi-axis CNC machines that can produce complex products on a single workpiece at one time. 5 axis milling reduces waste and highly cost-effective for prototype development.
