Cnc milling machine 5 axis

Types of 5 axis CNC milling machines

A CNC (Computer Numerical Control) milling machine 5 axis has five controlled movement parts or axis. This machine makes the work easy and cheap. It also gives accurate work. Some of the types of five-axis CNC machines are as follows:

• Fifth Axis Tilting Table:

  A CNC milling machine with a fifth axis rotating part is usually called a 3+2 axis machine. In this, the part that rotates is usually called a worktable or vice. Here, the first three axes are the normal ones, and in addition to this, there are two more stationary ones that are perpendicular to each other. This axis increases the number of positions of a product without any extra tooling. This kind of axis is easy to use and is cheaper than other five-axis milling machines.

• Direct Five Axis Machines:

  In this type of machine, all five of its axes move at the same time. The first three axes are normal ones, while the next two are those in which the parts rotate and tilt. These two rotating parts can be a part of the machine itself or a part of the product that is being worked upon.

  This type of machine gives the best accuracy and flexibility. It is good for complicated work. But it costs a lot of money and needs high skills to operate.

• Vertical Five Axis CNC Milling Machines:

  This kind of milling machine has a worktable in a vertical position. Many kinds of vertical machines are available in the market now. Most of the work on this kind of machine is done while standing. It cuts in a downward motion. This type of machine is good for a lot of work.

• Horizontal Five Axis CNC Milling Machines:

  This kind of milling machine has a worktable in a horizontal position. It is in line with the axis of the machine. When the worktable is in a horizontal position, it is good for work when it comes to accuracy and cutting power.
