What is High Volume CNC Machining?
High volume CNC machining refers to the production of large quantities of identical parts or products in a single run using computer numerical control (CNC) technology. This process is ideal for mass production, where efficiency, consistency, and precision are critical. Kesu Group’s high volume CNC machining services cater to projects ranging from hundreds to millions of parts, ensuring cost-effective manufacturing without compromising quality.
Key Processes in High Volume CNC Machining
Kesu Group employs a variety of CNC machining processes to meet the demands of high volume production:
- CNC Milling: Uses rotating cutting tools to create complex geometries, ideal for flat surfaces, slots, and 3D shapes.
- CNC Turning: Rotates the workpiece against a stationary tool to produce cylindrical parts like shafts and bushings.
- Swiss Machining: Utilizes sliding headstock lathes for high-precision, small-diameter parts, perfect for medical and electronics components.
Our facilities house over 100 CNC machinings, enabling us to handle projects of any scale with rapid turnaround times.
Small Batch vs. Mass Production
CNC machining can be categorized by production volume:
- Small Batch CNC Machining: Typically involves several to a few hundred parts, ideal for prototyping or low-volume needs.
