Types of Mini CNC 4 Axes

A mini CNC 4 axis machine has all the regular benefits of CNC machines with an additional rotation axis. The additional rotational axis makes the machine capable of having four axes instead of just three. Here are some types of 4 rotor CNC machines capable of doing extra tasks because of the additional axis.

• Mini CNC Router 4th Axis Rotating:

  This device's main feature is a rotary table or cylinder as its fourth axis. Generally, it will have three linear motion axes that are controlled like all CNC machines. The additional fourth axis will have a cylindrical object or a flat rotating table. The device can then carve out objects like logs of wood or metal cylinders with ease. This is done without the need for manual intervention. It can be used to make products with circular symmetry like bottles, candles, or vegetable containers. It is usually made out of a sturdy material like aluminum alloy. The load-bearing capacity can sometimes hold objects of up to 150 kg. They have a precise stepping motor and gear ratio to accurately do the rotary works.

• Mini CNC Mill 4th Axis:

  This machine is specifically for milling processes. It is designed to easily handle a workpiece of up to 60 X 70 cm. No other clamping or fastening tools are needed for the workpiece of this dimension. Its fourth rotational axis allows for more complex parts to be machined and crafted precisely and easily. Like other 4 axis CNC machines, the fourth axis here is controlled mathematically by software using a stepping motor to rotate the workpiece with precision.

• Mini CNC Laser 4th Axis:

  In this device, the fourth axis is used to carry a laser beam to etch or engrave objects like wood, metal, or plastic. The object to be marked is usually mounted on a rotary cylinder. The workpiece is then rotated to allow easy marking and engraving of the object. The laser can sometimes be a Laser Engraving Machine or even a Laser Cutting Machine. The problem of manually marking an object with irregular shapes is made easy here. The operator does not need to manually move the laser around to mark the object. The laser does its job automatically by the fourth rotational axis,.
