What are the main components of a CNC turret punch machine?

Turret punch machines are an indispensable part of heavy part manufacturers. It is different from a laser-cutting machine in the sense that it punches the metal sheets to form different shapes applicable to the concerned industry. However, turret punch machines have limited applications because they cannot carve out custom shapes for various applications. These machines are best for repetitive shapes such as air conditioning cases and such.

However, if you work in a niche industry, turret machines are your best bet for metal shaping because they work faster than laser-cutting machines. Hence, you can shell out more number of parts in a limited amount of time.

Additionally, turret machines today are CNC-enabled, which means that the entire process is automated via CAD and CAM tools. Manual supervision and frequent adjustments are not required, which makes turret machines quite efficient. In this article, we will talk about the main components of a CNC turret punch machine to make your job easier.

Upper and Lower Turret

Upper and Lower turrets are the components where several tools are set. You can mount a wide range of tools on these turrets depending on your needs and requirements. The turrets on CNC turret punch machines are then rotated with the help of CNC control to get the desired output with accuracy. It is pertinent to note here that one must be very careful with the alignment of the upper and lower turret.

In case of misalignment, there is a high chance of tool breakage, which can increase the production cost due to repairs. Therefore, it is recommended by the experts that regular maintenance with alignment fixtures must be done by the operators.


Striker, as the name suggests, is the driving force behind the turrets. It is shaped like a slider that operates with the help of hydraulic force, servomotor, etc. It has two functions mainly; one is to facilitate the transmission of driving force to the tool. And another is to provide the downward movement of the upper turret as a punch.


The clamp is based on the base of the turret machine. This part is used to hold the material in place. The tools on the turret are applied to the material by moving the base using CNC control. This is done in accordance with the CAD and CAM design.

Turret Key

A turret key is used to position the tools that have a certain angular design to them. The turret key is the main component if you want your tools to move properly in the direction of rotation of the turret. It is pertinent to note here that just like the upper and lower turret, the turret key also requires proper upkeep and maintenance. Any damage to the turret key leads to misalignment, which may result in tool damage. Therefore, we recommend you hire industry professionals to take note of the turret maintenance.


Lifters, as the name suggests, are tasked with holding the upper tools in place once their task is done. This means that this component is used to send the upper tools back up after they have punched the material positioned on the base.

Die Holder

In contrast to the lifters, a die holder is set on the lower turret. However, one must be diligent with the contamination that may occur on the die. This happens when powdered dust or slug gets mixed with the holder. In such a case, there is a high risk of tool failure.


In this article, we have listed down all the important components of a turret press machine, so you can ensure proper maintenance. Additionally, knowledge of components will allow you to work diligently with the machine and diagnose the damages without delay.
