WorkBee CNC Router Machine Full Kit


The WorkBee is a culmination of all our experience, feedback, and suggestions from selling the OX CNC Machine.

Based on C-Beam, V-Slot, Xtreme Solid V-Wheels and Tr8*8(P2) Lead Screws it is strong, accurate and reliable.

Please note:

  • High Torque Stepper Motors are recommended with the 2.2kW Water Cooled Spindle.
  • With the GRBL Controller bundle we recommend using external stepper drivers when pairing with High Torque Stepper Motors in order to utilise them at their maximum capacity.


The Bulk Man 3D WorkBee was originally designed by Ryan Lock of Ooznest UK, and it incorporates many upgrades. It is a super-strong, accurate and easy to assemble CNC machine.


The WorkBee CNC design has gone through different changes. WorkBee Version 1 originally had the leadscrews placed in compression. All Bulk Man 3D’s WorkBee kits now sold are Newest Version, with the major differences being the use of Tingle Tension System and longer leadscrews in the X and Y Axis. This helps to solve the problem of Whipping when for long length or faster Speed,which is very popular in CNC machine market.

Based on C-Beam, V-Slot, Xtreme Solid V-Wheels and TR8x8(P2) Leadscrews it is reliable. It has been carefully designed and can accurately cut foams, woods, plastics and aluminum to 0.1-0.2 mm accuracy or better.

The WorkBee CNC Machine is a 4 axis (3 + 1) machine, this means there are 3 physical axis (X,Y,Z) and a slave axis of Y which is called the A Axis. The WorkBee CNC Machine uses specific lengths of Extrusions and Leadscrews.

With a WorkBee CNC Kit you can manufacture functional engineering parts, toys, signs, or whatever you can imagine without leaving the workshop.


The Cable Drag Chain bundle contains all the hardware for mounting Cable Drag Chains on your WorkBee, Ox CNC or other CNC machine to help with cable management.

Mach3 (NVUM / STB5100 / UC300) and GRBL / GRBL Nano High Torque Controller Bundle are perfectly used for engraving machine.

The 1.5kW or 2.2kW Air / Water Cooled Spindle Bundle contains all the hardware for mounting a the Spindle on your WorkBee or other CNC machine.
