Latest Version Work-Bee CNC Mechanical Kit with Tingle Tension System
Bulk-Man 3D is the largest wholesaler of Open Source CNC parts to the world. By having the parts produced ourselves, or sourcing the parts directly from the factory, we eliminate the middle man and in doing so are able to provide the best wholesale price direct to the public!
The Bulk Man 3D Work-Bee Newest Version is based on the original WorkBee design by Ryan Lock of Ooznest. Our kit has some differences to the original design by Ryan including additional wheels and an Upgraded Tension System with longer leadscrews, which allows for stronger and more reliable tension to be placed on the X and Y Axis lead screws, and helps to solve the " Whip" problem for long lead screws or faster Speed.
It is reliable based on C-Beam, V-Slot, Xtreme Solid V-Wheels and TR8x8(P2) Leadscrews. It has been carefully designed and can accurately cut foams, woods, plastics and aluminum to 0.1-0.2 mm accuracy or better.
The Work-Bee 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 Work-Bee CNC Machine uses specific lengths of Extrusions and Leadscrews.
With a Work-Bee CNC Kit you can manufacture functional engineering parts, toys, signs, or whatever you can imagine without leaving the workshop.
Advantage:This kit is the latest version comes with a new Tension System to minimise Lead Screw ‘Whip’ !

Z Height
54mm Or 94mm Travel, 27mm Or 47mm Workable depth, with a 12mm spoilerboard.
The spoilerboard supports have two height configurations, these are the maximums for each configuration.
Motion
Drive System- ACME Lead Screws or GT3 Timing Belts
Linear Guides- Polycarbonate wheels on anodised C-Beam V-Slot Extrusion.
Motors- NEMA23 175oz Stepper Motors (X, Y & Z)
Accuracy- 0.05 - 0.10mm (Screw Driven) or 0.10 - 0.20mm (Belt Driven)
Note- Maximum recommended speed for Lead Screws 1000mm or greater is 400RPM.
The Work-Bee is available from regular size 500x750mm up to 1500x1500mm both for screw driven and belt driven!
The Work-Bee CNC also has two different spoiler board configurations. One for shallow work up to 27mm deep, and a lowered setup to 47mm deep. Having this option is beneficial. If the plan is to only cut thin materials, it is a waste of rigidity to have the Z-Axis reach down more than needed. The Screw Driven version, right image above, shows the lowered configuration.
Z Travel Explained
The Work-Bee has two spoilerboard support configurations. One with a travel of 66mm, and a lower one with a travel of 106mm. The reason for the two configurations is that if the machine is always used to cut thin materials, for accuracy reasons it is better to have the work piece as close to the Z-Actuator as possible, so in this case the machine should be setup in the higher 66mm travel configuration.
The higher configuration has a Z travel of 66mm, with a 12mm spoiler board, this will reduce the Z travel to 54mm. In this case 54mm is maximum thickness of material that will fit on the machine.
To calculate the max cutting depth for a chosen piece of material it is:
Max Cutting Depth = Z travel – Material Thickness
For instance a setup with a 12mm spoiler board, the max Z travel is 54mm, so when cutting into a material 30mm thick the max cutting depth would be:
Max Cutting Depth = 54 – 30 = 24mm
This means with a 30mm piece of material it would not be possible to cut it the whole way through.
The max thickness that can be cut the whole way through is half the Z travel. So with a Z travel of 55mm, 27mm is the maximum thickness of material that could be cut the whole way through. And for the lower configuration the maximum thickness that can be cut the whole way through is 47mm.
