Custom CNC Mill-Turn Brass Precision Component
This custom brass component combines CNC turning and milling for cylindrical features, precision threads, bores, radial holes and complex machined details.
CNC mill-turn machining allows turned and milled features to be produced efficiently with fewer setups, making it suitable for precision components used in automation, industrial equipment and mechanical assemblies.
Parts can be custom manufactured according to customer drawings, material specifications, tolerances and surface finish requirements.
Typical Applications
• Automation Equipment
• Industrial Machinery
• Sensors & Control Systems
• Valves & Fluid Components
• Electrical & Mechanical Assemblies
• Custom Equipment
