It is necessary for a machine to communicate with a robot if the features are to be exploited, safety assured and optimum performance achieved. The link means that the robot system and the CNC machine can work together.
A good example of this is that the robot must know whether the door of the machine is open or not. For this, the machine sends a signal to the robot that the door is open. The robot then knows that it may load the product into the machine’s clamp. After this, the machine needs to know once again that the product is in place, so that it can grab it. It can then, in turn, send a signal to the robot to tell it that it can release the product.
What is needed to link a machine?
Before a robot unit is sold, we always ask the question: “What type of robot interface does your machine have?” The answer to this question allows Cellro to determine which machine link we need to configure. That can, for example, be Profibus/Profinet, Ethernet, hard-wired IO or Fanuc IO link. Cellro is flexible in this regard; machine manufacturers have their own protocols and machine controls. As a manufacturer of automation solutions, Cellro is able to adapt accordingly.
It is beneficial for us if we receive the CNC machine’s technical data from the customer. This usually consists of the following:
- CNC machine electrical diagrams;
- Description of the robot interface;
- Description of the interface connectors use;
- On the basis of the above information, Cellro is able to advise you on which machine link will function with your machine.
I have no idea what type of machine interface I have.
The age of the machine does not have to be a reason for a link to not be made. It depends on how the machine was designed and produced. Cellro would be pleased to examine whether a type of machine is suitable for a machine link. Do you have more questions about this? If so, contact one of our experts today.
My machine still has to be updated. What are the requirements?
Machine interfaces are extremely different. A standard list of requirements cannot be drawn up. If you would like to automate using robot automation, Cellro will willingly indicate what the update of your machine should include. (We prefer to work with Profibus/Profinet or hard-wired IO.) The machine manufacturer can prepare the link based on the document received. Do you have any additional questions? If so, contact one of our experts today.
Machine link and safety
It is necessary for the machine to send a signal to the robot and vice versa for them to work together. The machine link at Cellro goes a step further. In exceptional cases, something could go wrong. If this happens, the systems must be able to detect the problem and switch the machine and the robot cell off. The same applies in the event that an employee presses the emergency stop button; the machine and/or robot cell must be switched off. Cellro is able to send these safety signals.

Automating several machines
Xcelerate can be linked to different CNC machines. The software allows four machine interfaces to be prepared. Thanks to a “smart” connector, Xcelerate knows to which machine it is linked. The only thing the customer has to do is move Xcelerate mechanically from machine A to B. The rest is done automatically.
Collet and Fixture Exchange and machine link
If you want to use a Collet or Fixture Exchange module, a more extensive interface is required so that it, too, can be automated. The interface must now have “number” communication. This enables NC numbers/names to be sent from the Xcelerate Jobmanager to the machine. Want to find out all about this feature? Please do not hesitate to contact one of our experts.
What else is required to automate your machine?
- Machine link.
- Automatic door (using an air cylinder or servo-drive)
- It is possible to automate your machine even if the machine manufacturer is not able to automate the door. Cellro may be able to do this for you.
- Fixture Exchange Module
- Air flow(s) through the table (for a 5-axis machine)
- Zero-point clamping system
- Automatic machine clamping
Collet Exchange Module
- Hainbuch Interface for Collet Exchange
