Difference Between Pocket NC And Desktop NC
Mar 29, 2025
Leave a message
Pocket NC and Desktop NC are both desktop 5-axis CNC machine, but there are differences in their design goals. Desktop NC has performed well in medical and precision manufacturing fields such as invisible tooth socket cutting and aircraft model parts processing, supporting direct import of G-code and CAD/CAM software. Pocket NC is mainly used for basic teaching of metal cutting, and its fully enclosed protective cover and pneumatic lifting door design enhance teaching safety, making it suitable for vocational colleges to carry out five axis programming training. The actual case shows that Desktop NC can process 0.3mm stainless steel micropores, while Pocket NC focuses on demonstrating basic five axis machining principles such as four axis linkage.

In August 2021, we delivered a similar set to MIT professor Ben Katz (MIT Mini Cheetah: https://www.youtube.com/watch?v=xNeZWP5Mx9s and the fastest Rubik's cube solving robot in the world: https://www.youtube.com/watch?v=nt00QzKuNVY) using our Desktop NC machine to make parts for similar robotics projects as follows:
