The Lead Machine is a robust CNC router platform.  Designed by OpenBuilds, this platform is  designed to use standard parts with no custom plates.   It is made entirely of extruded aluminum sections with good strength and rigidity.   A sturdy base with front and back full width legs provides stability, and C-Beam extrusions form the axis tracks.  The V-groove profile provides very good rigidity with little weight.  The kits include all mechanical parts needed for the machine, including standard NEMA 23 motors.  Travel is somewhat less than the overall length to allow for width of the carriage, etc.

The Y-Axis rides on a pair of 8 wheel carriages on the c-beam extrusions.  An additional 2 or 4 wheels can easily be added to each plate for more stability.   Each carriage has an inner stiffener plate to further reinforce the carriage.  The Y - Gantry plates are machined aluminum, (not plastic as on some versions) and connected to each other with a c-beam extrusion that forms the track for the X-Axis.  The wide wheel spacing provides maximum strength and stiffness, while allowing the carriages to move freely.  There are 2 Y-Axis NEMA 23 motors, one for each side of the Y-Axis.   For screw drive, the motors are mounted on the integral plates on the back of the c-beams, with the screw drive also running inside the c-beam pocket and protected from debris.

The side plates support an 80x20 extrusion on each side to support the X/Z gantry.  This can be optionally lengthened to provide more Z travel.  It may be rquired to increase the Z axis length if this is done. 

The X-Z axis carriage rolls over the c-beam extrusion connecting the side gantry plates, with a screw drive system.  This beam is very strong.  There are 2 sets of double v-wheels that roll on top of the track for strength, and two sets of double wheels on the bottom of the X-Axis carriage. Either of these can have an extra pair of wheels added to strengthen the carriage.  The wheels connect a pair of gantry plates front and back of the track extrusions for added strength and stiffness.  The motor mounts on the end of the axis on one of the end plates.  The front gantry plate mounts the 4 vertical v-wheels for the Z-Axis traveller.  2 more wheels can be added for increased rigidity.

The Z-Axis C-Beam extrusion is 250mm in length, with a travel of a little over 80mm.   The Z axis is supported by 4 widely spaced v-wheels.  The Z-Axis actuator is lead screw driven by a top mounted stepper motor.  NEMA 23 motors are used throughout give additional torque for heavier spindle motors.   A 71mm heavy router mount is an option to use a Bosch Colt or a Dewalt Router.

An MDF spoil board is mounted in the bottom of the frame.  (Not included).
