Manufacturing engineers review drawings
±0.005 mm
Achievable on suitable geometries and materials
A production network matched to the part
From small, high-precision diameters to larger stock sizes and repeat orders, we align machine capability, process steps, and production capacity with your requirements.
Part scope
Turning capabilities for critical components
We assess part geometry, material, tolerance, and production volume to select a suitable machine configuration and manufacturing partner.
Shafts and spindles
Precision turning with close attention to concentricity and runout for rotating assemblies.
Bushings and sleeves
Controlled internal and external diameters for demanding fits and high-performance assemblies.
Flanges and fittings
Structural connectors with complex threads and coordinated hole patterns.
Fasteners and standoffs
Custom hardware produced to drawing for specialized equipment and assemblies.
Technical scope
Material, process, and finish in one plan
Choose from a broad range of metals and engineering plastics, with secondary operations coordinated to deliver parts ready for assembly.
Turning processes
2-axis, 3-axis, and multi-axis turning, including live tooling. Standard tolerances can reach ±0.005 mm where part geometry and material allow.
Materials
Stainless steel 303, 304, 316, and 17-4PH; aluminum 6061 and 7075; carbon steel; brass; copper; and engineering plastics including POM, PEEK, and Nylon.
Secondary operations
Grinding, thread rolling, knurling, and broaching, coordinated alongside turning to suit the drawing and application.
Finishing and treatment
We can coordinate heat treatment such as hardening and nitriding, as well as anodizing, black oxide, passivation, and powder coating for finished, ready-to-assemble parts.
Supplier matching
The right turning resource for your production profile
Rather than forcing every project into one factory, BG CNC matches diameters, lengths, tolerance needs, and order volumes to the relevant equipment and supplier capacity.
Engineering-led manufacturing
Resolve drawing risks before production
Our team of 10 manufacturing engineers reviews drawings for manufacturability, balancing functional requirements with cost, material choice, and process capability.
-
Optimize tolerances
Identify unnecessarily tight tolerances that add cost without improving functional value, while preserving requirements such as concentricity, thread fit, and dimensional stability.
-
Select the right material
Review material grades against the application, machinability, mechanical properties, and cost.
-
Consolidate process steps
Coordinate turning with heat treatment and surface finishing through the supplier network, reducing the burden of managing multiple vendors.
Quality and consistency
Quality oversight throughout the supply chain
Depending on your industry and project requirements, we match production with partners holding relevant certifications such as AS9100D, IATF 16949, ISO 13485, or ISO 9001.
First article inspection
FAI reports to review initial parts against drawing requirements.
Material traceability
Documentation to support material verification and production records.
Inspection checkpoints
In-process and pre-shipment inspections tailored to the part and project.
Protective packaging
Controlled packaging helps protect precision threads and polished surfaces during international shipping.
