# spectraLIGHT CNC Mill

## Description

The spectraLIGHT is a mini mill from Sherline contained in an enclosure and adapted to CNC. It uses specialized Morse 1 taper collets that hold tools up to 1/4". It can hold tools with a larger shank (up to 1/2"), as well as a drill chuck and other tooling (such as a fly cutter), via an external thread on the spindle. The spindle is electronically controlled and variable from \~0-10,000 RPM

VCarve can be used for toolpath generation, though Fusion360 is recommended for greater flexibility.
