Professional CNC Bar Machining Services Services

AOOM Technology's CNC bar machining services combine high-speed automated production with precision engineering to deliver consistent quality components at competitive prices. By utilizing advanced CNC turning centers equipped with automatic bar feeders, we achieve efficient lights-out production that reduces per-part costs while maintaining tight dimensional control. Our expertise spans simple shaft turning through complex multi-operation components requiring milling, cross drilling, and threading in a single setup, eliminating secondary handling costs.

Key Technical Specifications

• CNC turning centers with automatic bar feeders supporting bar diameters from 3mm to 80mm for flexible production capability
• Multi-axis Swiss-type turning machines for complex bar-fed components with secondary operations in a single setup
• Tolerance capability of ±.005mm on diameters and ±.01mm on axial positions with SPC monitoring and adjustment
• Material range encompassing aluminum, stainless steel, titanium, brass, copper, steel alloys, and engineering plastics in bar stock
• Live tooling capability for cross drilling, milling, slotting, and threading without secondary setups or extra operations
• Bar length capacity up to 4 meters with automatic remnant management for optimized material utilization
• Surface finish as-machined Ra 1.6μm standard, with finishing options to Ra 0.4μm and electropolishing available
• Automated part evacuation and sorting for high-volume production with minimal operator attention required
• In-process gauging and tool wear monitoring for consistent dimensional control across extended production runs
• Polygon turning and eccentric turning capability for non-round bar-fed components requiring specialized machining
• Thread rolling and thread whirling for high-strength threaded components in medical and aerospace applications

Applications

• Precision shafts and spindles for electric motors, pumps, and rotary actuators requiring concentricity within microns
• Hydraulic and pneumatic piston rods, valve spools, and cylinder components for fluid power system applications
• Automotive fuel injector components, ABS sensor housings, and transmission valve body parts for high-volume production
• Medical bone screws, drill guides, and instrument shafts machined from implant-grade stainless steel and titanium bar stock
• Electronic connector pins, sensor housings, and terminal blocks for industrial and consumer electronics applications
• Fastener-grade components including studs, bolts, and custom threaded parts for assembly applications
• Hydraulic fitting adapters and swivel joints for mobile equipment and industrial machinery fluid systems

Quality Assurance

AOOM Technology maintains ISO 9001:2015 certification with quality processes specifically adapted for bar-fed production environments. Statistical process control is implemented on critical dimensions with real-time monitoring and automated adjustments where applicable. First-article inspection provides comprehensive dimensional verification before production release. Bar material certifications are verified against purchase specifications and maintained in our traceability system. Final inspection includes dimensional measurement, surface finish verification, and visual inspection per defined acceptance criteria.
