CNC Kits and Components
Here you will find products to help in the building of your own CNC machine. There
are variations and alternatives, so I am making an effort to provide the most useful
products to conform to any type of build. If there is a product that you would like
to see, let me know. Please read the
conditions of purchase and shipping prior to purchasing any products offered
by BuildYourCNC.com.
blueChick CNC Kit 4.2 - Complete Kit
The desktop sized CNC machine with a routing area of 12"x36". (Driven by Roller
Chain)
Timing Belt
Single sided timing belt (belt with trapezoidal teeth) to keep a good position with
linear motion applications. Urethane with Kevlar cords, pitch is .200" and the width
is 3/8". This item is sold by the foot. Update the quantity with the number of feet
desired.
Machine Assemblies Quick Links and How to Purchase:
It's easy to get overwhelmed with what to purchase to create you very own CNC Machine
or CNC Router. The following list wil provide you with generally what you will need
for certain condition:
Electroincs:
All Machines will need power to move each axis. This is done with
Motors, Drivers, Breakout board and Power Supply. You will generally need
3 motors and drivers in all. Other components that accompany the motors and drivers
are a power supply to provide power to the motors, and a breakout board which conveniently
interfaces the computer to the motor drivers.
Machines with Roller Chain Based Drives:
Roller chain drives will move the machine's axes using
sprockets that ride along a roller chain.
Generally, you will need 4 main components per motor. These components consists
of one drive sprocket, one
collar to allow the drive sprocket's bore to securely fasten to the motor
shaft, one idler sprocket, and a specific
length of chain. The chain will be
the length of the axis to which it will be applied with additional length to account
for structure.
Machines with Lead Screw drives:
If you are interested in creating motion with lead screws and nut, you will first
need a lead screw. The lead screw will need to be stabilized and be able to turn
freely. This is done with bearings and collars. For
each lead screw, you will need two bearings with the inside diameter that matches
the diameter of the lead screw, and you will need two collars with inside diameters
that match the diameter of the lead screw. To couple (attach) the motor's shaft
to the lead screw, you will need a coupling. Couplings offered here come in three
parts, one hub (end) that matches the motor shaft diameter, another hub that matches
the diameter of the lead screw, and an insert (rubber spider) that fits between
the two hubs to permit a flexible connection.

Bearings - For Linear Slides
These package counts are based on the common machine requirements. Specification:
5/16" inner diameter, approimately 1/4" thick, and the outside diameter is approximately
7/8".
8 pack One Axis Set
24 pack Three Axes Set
30 pack (Three Axes and two for each leadscrew)
Bearings - Position 1/4" Lead Screws
Use these bearings to stabilize your 1/4" lead screw next to the coupling. Two per
axis is usually needed to secure the entire lead screw.
6-pack
Bearings - Position 1/2" Lead Screws
Use these bearings to stabilize your 1/2" lead screw next to the coupling. Two per
axis is usually needed to secure the entire lead screw.
6-pack
Bearings - Position 3/8" Lead Screws
Use these bearings to stabilize your 3/8" lead screw next to the coupling. Two of
these bearings are typically used for each lead screw, one bearing at each end of
each lead screw.
6-pack
Bearings - Position 5/8" Lead Screws
Use these bearings to stabilize your 5/8" lead screw next to the coupling. Two of
these bearings are typically used for each lead screw, one bearing at each end of
each lead screw.
6-pack
Limit Switch
Limit switches serve as the mechanism that tells the computer the limits of the
CNC machine. When one of the axes moves to an axis limit, the switch is activated
and the machine stops. These limit switches are also use to inform the computer
of the home position. Typically, 6 of these switches are needed, two per axis.
