Frequently Asked Questions About CNC Machining Parts Manufacturer
Why Do Production Capacity and Fast Delivery Matter?
A top CNC machining manufacturer needs to have the capacity to meet both urgent and large-scale demands. A factory with a large footprint, like VMT’s 5,000 m² facility, and a significant number of employees demonstrates the scale needed for efficient production. The number of machines, especially 100 sets of advanced CNC centers, is a direct measure of their ability to handle multiple projects simultaneously.
Is CNC Machining Part of Manufacturing?
Yes, CNC machining is a fundamental part of modern manufacturing. It uses computer-controlled tools to precisely cut and shape materials like metal, plastic, and wood into finished parts.
It is widely used across industries such as aerospace, automotive, electronics, and medical for making both prototypes and end-use parts due to its accuracy, consistency, and efficiency.
How Many Parts Can a CNC Machine Manufacture Per Year?
The number of parts a CNC machine can produce per year depends on part complexity, material, cycle time, and shift hours. Simple parts can be made faster, while complex parts take longer.
Roughly, one machine working 8 hours a day can make:
-
Simple parts: 20,000–100,000+ annually
-
Complex parts: 1,000–5,000 annually
With 24/7 operation or multiple machines, production can reach into the millions.
