CNC Milling & Drilling Services
Built for Tight Tolerances and
Fast Turnarounds.
Our CNC milling services and CNC drilling services support engineers and product teams who need precision machined components without the overhead of maintaining their own machine shop. From one-off prototypes to repeat production runs, we machine brackets, panels, enclosures, heat sinks, fixtures, and structural components using vertical machining centers, horizontal machining centers, and multi-axis equipment programmed with CAM software and verified through CMM inspection.
- 3-axis, 4-axis, and 5-axis milling capability across vertical machining centers and horizontal machining centers, handling complex geometries, undercuts, and multi-sided parts in a single setup.
- Tolerances down to ±0.001" with geometric dimensioning and tolerancing (GD&T) per ASME Y14.5, verified through CMM, optical comparators, calipers, micrometers, and first article inspection.
- Materials span metals and plastics including aluminum alloys, steel alloys, stainless steel, titanium, brass, copper, bronze, Delrin, and engineering composites machined with carbide tooling and coated tools.
- DFM review built into every quote to catch issues with wall thickness, corner radius, hole diameter, thread specifications, and fixture design before toolpaths are programmed.

Why Cusack
What Sets Our CNC Milling Services Apart
Integrated Workflow, Faster Delivery
CNC milling services, CNC drilling services, powder coating, UV printing, and product assembly all happen in the same facility, eliminating shipping delays and vendor coordination while compressing your overall timeline.
No Minimum Order Quantities
We machine single prototypes and production runs of 10,000+ pieces with the same attention to tolerance, surface finish, and delivery commitments. No job is too small or too large.
Engineering Team on Staff
Mechanical engineers review your designs for DFM issues, recommend material alternatives, optimize toolpaths for cycle time, and answer technical questions throughout the project without charging engineering fees.
Material Traceability & Certifications
Full material certifications, mill test reports, and first article inspection documentation available on request, supporting quality systems aligned with ISO 2768, ASME Y14.5, and customer-specific requirements.
Prototype to Production Continuity
Start with quick-turn prototype machining, refine the design, then scale directly into low-volume or high-volume production with the same fixtures, programs, and quality standards already validated.
Competitive Pricing Without Quality Compromise
Custom CNC milling services priced to compete with offshore shops, delivered on domestic timelines, with engineering support and quality inspection you can verify before shipment.
