Cnc router kit for home or small business
This Cnc Router Kit that is available on www.cncconversionkit.com is a complete set to build a Cnc Router Machine it is design for machining metals such as : steel, aluminium, capers and more. Machine comes with 4 TBI ball screw, Q16 mm pitch 5 mm precision C7. Thickness of the aluminium plates that we use to build the machines are 3/4 ” and 1/2” , aluminium extrusion model 6060,
6 x 25 mm V linear with 12 linear guide block. These Instructions will show you step by step how to build a Cnc router machine . If you have any question please call us.

Cnc router kit machine Frame
(Step 1) Build Cnc Router Frame made of 6060 aluminium extrusion.
You have 8 pieces of aluminium extrusion
2x for Y axis ( the longest )
2x for X axis ( middle size )
4x support for the frame ( the shortest )
Now we need to take 2x Y axis aluminium extrusion ( the longest ) and the 4x support aluminium extrusion. ( the shortest )
( Step 2 ) Now we need 4x big corner brackets and 8x smaller brackets. For each big bracket you need 8x 1/4 – 20 screws and 8 T- nuts total of 32 screws and 32 T-nuts. Smaller brackets 4x screws 1/4 -20 and 4 T-nuts total of 32 screws 1/4-20 and 32 T-nuts.
( Step 3 ) The Small corner brace bracket has to be tighten with 4x 1/4 – 20 1/2 L T-Nut.
( Step 4 )
Now is time to add legs on to the Cnc router frame, Take 4x 80 mm aluminium extrusion and 4x smaller brackets each bracket goes to each leg we need 16x 1/4-20 1/2L screws and 16x T-Nuts.
( Step 5) You have 6x Guide linears 25 mm with 12 V block, first tighten the M6 screws 20 mm long with T-nuts.
after slide it in to the extrusion set up and tighten only one side.
( Step 6 ) Now we have to take the 2 aluminium side plate and setup the Y axis ball screw nut mount, the mount is made from 20 mm aluminium plate.
( Step 7 ) Add the ball screw nut mount to the big aluminium side plate to do that we need a square angle ruler.
( Step 9 ) It is very important to setup the ball screw nut mount perpendicular to the side aluminium plate because after we slide the Y axis ball screw in the Y axis nut mount.
( Step 10 ) The picture below shows how to setup the ball screw nut mount. Place the angle square ruler setup the ball screw nut mount and tighten with 2 M8 screws and 2 M8 washers.
( Step 11 ) It is to very important to setup the linear bearing block mount perpendicular to the side aluminium plate, set the angle square ruler to 100 mm, take the 4 M8 screws and 4 washers.
( Step 12 ) After you set the mount tighten the 4 M8 screws
( Step 13 ) Time to add 3 linear bearing block support mount you will need 19 M6 30 mm L screws and washers , 4 M6 25 mm screws and 4 washers.
First we have to tighten the 4 25 mm M6 screws.
Now we have to add 9 M6 screws 30 mm L same with the other side.
3 linear bearing block support mount
( Step 14 ) Place the second aluminium side plate to the linear, do not tighten them. now we have to add the X axis Ball screw but before you add it tighten the nut mount with 10 32 7/8 screws.
Our Cnc router is ready for the X axis V linear and bearing.
Take the X axis aluminium extrusion , X axis linear setup and M6 20 mm L and T-NUT.
Take 24 M8 screws with washers and tighten the extrusion to the aluminium side plate.
Now we can tighten the Y axis linear bearing to the bearing support.
( step 15 ) Now its time to add the Z axis to the machine, first take the ball screw and tighten the ball screw nut mount to the ball screw with 6 10-32 7/8 screws.
Next add the first 20 mm aluminium plate to the X axis Linear bearing and tighten it with 12 M6 30 mm , 4 M6 25 mm and 12 M6 washers.
Now we have to tighten the Z axis plate to the X axis ball screw nut bracket with 2 M8 35 mm screws.
( 16 ) The Z axis big aluminium plate, first we have to add the V linear and tighten it with M6 screw, then we need to set the linear to 12 . 5 mm from the edge of the big aluminium plate.
now we have to add the Z axis ball screw , first we need to tighten the ball screw nut mount to the ball screw with 6x 10-32 7/8 screws then we have to add the ball screw bearing housing on the top of the ball screw and on the bottom, Top bearing housing has to be tighten with 2 10-32 1/14 and bottom bearing housing with 2 10-32 7/8
Last part on the Z axis we have to add is spindle mount the spindle mount we have to tighten with M8 25 mm screw.
We have to take the big Z axis plate and tighten it to the a small Z axis aluminium plate with M6 30 mm screws with washers.
after tighten the ball housing to the small Z axis plate with 2 10-32 1 1/4 washers.
Z axis stepper motor mount has to be tighten with 2 10-32 1 1/4 screws and washers.
Now add the stepper motor to the Z axis Mount with 4 10-32 1/2 screws .
( step 17 ) Y axis ball screw , take 12 10-32 7/8 and tighten the Y axis nut to the nut housing.
The front bearing mount , remember you can only setup one side at a time, you need 8 M8 35 mm screws and washers for the front and the same for the back the same screws.
