What is a 3-axis CNC machine?

A standard 3-axis CNC milling machine has a table that moves the part to provide one or two planes of movement and a tool that provides the other one or two planes of movement. 3-axis machines are ideal for simple tasks that don't require intricate detailing or depth.
3-axis CNC machining evolved from rotary filing. With a 3-axis CNC machine, the workpiece is stationary while the cutting tool moves across the X-, Y-, and Z-axes. The X-axis (vertical axis) is left to right along the lathe table, the Y-axis (horizontal axis) is from front to back of the table, and the spindle that drops from the top marks the Z-axis (depth). A standard 3-axis CNC milling machine has a table that moves the part to provide one or two planes of movement and a tool that provides the other one or two planes of movement.
3-axis machines are ideal for simple tasks that don’t require intricate detailing or depth. As such, it is one of the most preferred techniques for creating mechanical parts for automation. Additionally, you can also use it for cutting sharp edges, boring, milling slots, tapping, and drilling holes.

Frequently Asked Questions
What is the difference between 2.5 and 3-axis CNC?
-
A 2.5 axis machine really has three moving axes, but only two axes can move together (most machines sold today are full three axis machines). For machining centers, a three axis machine will have three linear axes. A four or five axis machine will have three linear axes as well as one or two rotary axes.
What is the difference between 3 and 4 axis CNC?
-
The primary distinction between the two is that, unlike 3-axis machining, the 4-axes machining process provides an additional axis of rotation besides the regular 3-rotational axis. A user can conveniently machine four sides of a component for a single fixture setup.
What is the difference between 3-axis and 4 axis CNC?
-
The 3-axis machining center can only do single-surface machining but is the most widely used. The 4-axis machining center has an additional rotation axis which can realize multi-surface machining and improve processing efficiency.
