Alloy CNC Parts
NOWARUN produces custom alloy CNC parts machined to customer drawings using 4-axis and 5-axis CNC machining, milling, and grinding. Parts are held to tolerances down to +/-0.005 mm in alloy steel, carbon steel, stainless steel, or aluminum. Secondary heat treatment options including carburizing, quenching, tempering, and induction hardening are performed to meet specified core and surface requirements before final surface finishing.

Key Benefits
- Machining tolerance down to +/-0.005 mm on critical alloy CNC features for consistent assembly fits
- Multi-axis 4-axis and 5-axis CNC milling and grinding handle complex geometries in fewer clamping setups
- Heat treatments such as carburizing, induction hardening, and QT provide required hardness and wear resistance
- Wide finishing options including Geomet, Dacromet, anodizing, plating, and powder coating protect against corrosion
- Manufactured strictly to print or sample rather than catalog standards to fit bespoke assemblies
- Quality management verified through ISO 9001 and ISO/TS 16949 / ISO/TS 16949 manufacturing standards
Problems It Solves
- Machining distortion and tolerance drift on multi-sided parts resolved through 4-axis and 5-axis machining operations
- Premature component wear in demanding service resolved by induction hardening, carburizing, or quenching and tempering

Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| 3-axis CNC machining | 5-axis CNC machining handles complex multi-sided geometries in fewer setups, though programming and machine hourly rates are higher |
| Standard catalog machinery brackets | Custom alloy CNC parts match your exact housing geometry and fit requirements, but require upfront engineering review and production lead times |
| As-machined unhardened alloy steel | Carburized or induction-hardened parts resist surface wear under heavy mechanical loads, though thermal processing adds steps to manufacturing |
