We are excited to offer CNC milling at the Hunterdon County Headquarters Library Makerspace. The machine is available for use free of charge after a safety and materials orientation. The Bantam is optimized to mill aluminum but can also be used with other soft metals such as brass and copper, engineering plastics and hardwoods.
CNC milling is a form of subtractive manufacturing that transforms a stock piece of material such as a block of aluminum into a finished product (many times a prototype) using digital instructions to tell it the path to follow. The CNC machine follows the computer-aided manufacturing (CAM) or computer-aided design (CAD) file uploaded to the machine. Different size end mills are used to make a variety of cuts.
