Rat Rig Mill
Introducing the Rat Rig Mill - an all-metal, compact, and sturdy desktop CNC machine designed to meet the demands of hobbyists, makers and fabricators.
All Metal Construction
All metal construction, no plastic on structural or kinematic components.
40 series extrusion based frame
The 40 series extrusion based frame, M8 fasteners, and the full size XY plates provides a sturdy and stable platform for your work, allowing you to cut aluminium and steel. The double MGN15 rails with double carriages and TR8x8 lead screws transmission on all axes ensure smooth and precise movement, giving you great accuracy and repeatability.
Rat Rig Rodent Mainboard
We partnered up with BTT to develop a custom universal mainboard (grblHAL / FLUIDNC) for CNC machines with powerful drivers for high torque motors, a small form-factor, and an unmatched price.
Bellows
Bellows protect moving parts from dust and debris, keeping the machine precise and reliable over time.
FULL SIZE SPINDLE and milled aluminium Spindle mount
If you are a heavy duty user, you can choose the Advanced Electronics Bundle which features a Full size 2.2KW / 80mm spindle and VFD, for a no compromises experience. For lighter work, you can choose the basic electronics bundle for a sub 1000€ fully capable mill. The super rigid Rat Rig Spindle mount, made from aluminum and available in various diameters, opens the possibility of working with a wide range of tools and materials with ease and efficiency.
Compact size and Electronics Enclosure
With its compact size and configurable electronics, high-quality construction, advanced features, and an optional machine enclosure, the Rat Rig Mill will become an essential part of your workshop.
Optional machine enclosure (Coming Soon)
The optional enclosure is the perfect add-on for your mill, so you can keep your workshop clean and tidy from all the dust, chips, and burrs.
