There are numerous places available from where you will be able to get components or machine parts for CNC Milling. You can get various CNC parts
from online stores and can also obtain them from different stores.
You may get machines for different purposes, such as for cutting wood, for engraving someone on metal surface or for doing scroll work etc. Even if you are getting used parts, it is suggested to get new ones because used parts may be defective. But in case you have a tight budget, then you can go for used parts too, especially in the case of costly machine products, like CNC routers. You can find various parts which can be used in all of the CNC milling machines, and few of them are listed below. An axis is present in all CNC machines, and it could be of ranges 1-6 axis that decides its functions and size. Other part which holds the cutting and milling components and moves along the axis is the column. Other important machine part that holds the keyboard, which is the medium to enter the G code into these machines, is the control panel.

You would also need coolant supply tubes to pump some coolant to keep the machine cool, and to make the cutting tools lubricated.
You should go for the components according to the kind of machine you are working with since a lot of CNC Machining are available. There are horizontal CNC milling machines and vertical CNC milling machines too, along with other types like knee mills.
