High Volume CNC Machining Services
Automated, Scalable, Cost-Efficient Precision Parts at Unmatched Volumes
When your production demands high volumes of parts per year, Coley’s delivers. We provide fully customized, automated CNC machining solutions designed for the long-term production of hundreds of thousands to millions of precision parts annually.
Is High Volume Machining Right for Your Business?
High-volume CNC machining offers an unmatched ROI for OEMs, multi-brand conglomerates, and any other company producing repeat-use parts at scale. This approach is ideal if you:
- Require hundreds of thousands to millions of parts per year
- Can commit to a long-term production agreement
- Produce parts with minimal design changes over time
- Want to reduce operational costs, floor space, and labor
- Need fully automated, just-in-time delivery at scale
Don’t worry, smaller volumes may still qualify. If your part and forecasted demand justify automation, we’ll find a solution.
