Machine Tending
With a Cobot

Machine tending is one of the most common applications for cobots. Collaborative robots automatically load workpieces into CNC machines. They increase the efficiency of the production line and shorten production times because CNC machines are utilized to their maximum capacity.

How Automated CNC Tending with Cobots Works

Machine loading, or CNC loading, with a collaborative robot is revolutionizing the manufacturing industry. By integrating robots into the machining process, not only are efficiency and precision increased, but workplace safety is also improved.

Collaborative robots, also known as cobots, work hand in hand with human employees because they are flexible and adaptable to various applications, for example, through simple tool changes.

In CNC machining, cobots take on tasks such as loading and unloading machines with workpieces. Human workers are relieved. Collaborative robots enable optimal utilization of machines. Resources can be used predictably and efficiently, which leads to an increase in productivity and enhanced competitiveness.

A robot-controlled machine tending process can be repeated endlessly as long as the robot continuously receives raw parts. Manual intervention in the process is possible at any time.

1 Door Opening and Part Removal

The robot opens the machine door, takes the part from a magazine, and places it into the machine.

2 Start of Operation

The robot closes the machine door and starts it.

3 Completion and Reloading

The machine signals the end of its process. Subsequently, the robot opens the machine door, removes the finished part, and places it into a magazine.

Additional Automation Options

Cobots can take over CNC machine tending and operate all types of processing machines, e.g., press brakes and milling machines. Depending on requirements, further steps can also be automated through add-ons:

Automatic Door Opening System
Automatic Clamping of the Workpiece in the Vice
Automatic Air Blasting of Workpieces
Simultaneous Operation of Multiple Machines
Robot Portability: If it is not needed at one machine, it can be moved to the next.

We Support You During Implementation

1

Evaluation of Your Processes
The process flow and components (weight, size, etc.) are coordinated on-site, and all necessary components and functions are documented by our team.

2

Configuration of Your Individual Application Afterwards, the appropriate robot model (payload between 6 – 25 kg, reaches from 900 – 1,700 mm) is selected, including the suitable tools and add-ons. A special focus is placed on cycle time. To keep this as short as possible, the question of possible interfaces must be asked in advance to make the process even more effective.

3

Delivery and Commissioning
After receipt of order and delivery, commissioning by a SPIE AUTOMATION expert follows.

How You Benefit from Automated CNC Tending

More Efficient Production

Production can be run more efficiently and without delivery delays, as a robot continuously loads and unloads. Thus, companies produce without interruptions. Even increased utilization is possible, as robots take on additional shifts when the last employee has already left the factory floor.

More Flexible Production

After the installation of an automated CNC machine, companies are competitive again and can react more quickly to short-term changes. Due to simple programming and quick retooling, the system can be rapidly adapted to new requirements.

More Value-Added Production

A worker, with the robot colleague by their side, can tend to multiple machines simultaneously and take on more value-adding tasks. Manual intervention is still possible at any time, e.g., for smaller batch sizes – a clear advantage over industrial robots.
