Question: 1 / 400

What is an important characteristic of a CNC machine's design for optimal performance?

Lightweight construction

Greater rigidity

Greater rigidity is a crucial characteristic of a CNC machine's design that significantly contributes to its optimal performance. The rigidity of the machine ensures that it maintains its structural integrity during operation, effectively absorbing vibrations and minimizing flexing. This stability allows for precise cutting and machining, leading to higher accuracy and consistency in the finished parts.

A rigid structure also helps in reducing tool wear and extending the lifespan of both the tools and the CNC machine itself. With greater rigidity, the machine can handle higher cutting speeds and feeds, improving productivity and efficiency. Ultimately, a rigid design is essential for achieving high-quality machining results and meeting the demands of modern manufacturing processes.
