Bantam PCB



Bantam PCB

From mills to lathes to industrial grinders, there are many types of CNC machines, each with their own unique capabilities. The Fabrication Studio offers 2 types of CNC machines, a Bantam Printed Circuit Board (PCB) cutter and a Carvey 3 axis router. 

The Bantam PCB cutter is a small 3 axis mill specifically designed to cut traces on single sided or double sided copper coated circuit boards.


Understanding the Technology

What is CNC: Computer Numeric Control (CNC) machining is a process where pre-programmed computer software directs the movement of factory tools and machinery, like lathes, mills and routers. 

CNC Materials: Pre-cut flat wood, plastic stock and PCB board.

CNC Benefits: CNC is used by many industries because it offers a high level of automation, greater accuracy and repeatability over the manual machining processes. 

CNC Disadvantages: CNC programming requires an understanding of the manual machining process, raising the barrier to entry beyond other manufacturing processes, such as 3D printing.
