Benchtop CNC Router Mills Metal as Well as Wood

The APSX Spyder CNC milling machine from APSX cuts metals, wood and plastic.

The APSX Spyder CNC milling machine from APSX cuts metal, wood and plastic. The company designed the Spyder to fill what it sees as a void in the CNC router market for machines that cut specifically metals, not just wood. The machine features a configured LinuxCNC and an embedded PC, monitor, keyboard and pendant. It uses a wall outlet to power its control box and monitor.

The liquid-chilled spindle operates in speeds ranging from 2,000 to 20,000 rpm and, according to the company, provides high torque at low speeds. A water-air mixing system facilitates cooling of the workpiece and the end mill. Steel shafts, hard anodized aluminum blocks, lead screws and strong stepper motors contribute to the machine’s rigidity. A solid concrete base is available as an option. 

The machine saves the X, Y and Z coordinates, enabling users to machine without homing the spindle. The system monitors spindle stress and can stop motion before too much workpiece or end mill damage occurs.
