There are many reasons to look into automation. The list of reasons can be endless but I want to touch on a few of the more common. My goal is to answer some of the questions many have but do not know who to ask or have faith they will get honest answers. These are just some of the more common ones and by no means a full list. If you have your own questions as always please feel free to ask and I am happy to answer.
Setting up a weld removal cell
Automated weld dressing
Just about every market can find benefit in process automation. From labor reduction to improving the total time in production there is value in the automation. For some it is the need to improve part to part consistency or just the basic improvement in the over all finished product.
Robotic application in finishing
From detailed sanding tasks to simple weld removal robotics have a place in finishing. We will take a look at an enclosure application and touch on some of the main points that the company was looking for and how we got there. As always I respect the privacy of the people I work with and to that I will not share more than the company involved approved. So I can not show the final system in detail but can give a good idea of it in general.
Follow up on enclosure finishing.
I received so many really good questions I thought it may be helpful to share some with the answer to help others that may be faced with the same questions or problems. I am going to try and not go too deep and keep it easy to understand. Be aware the dynamics of each situation and the parts will be different. Keep sending me those questions as I enjoy good questions.
Working with extrusions
Working with an extrusion is one of the things that seems easy but the devil is in the details. Its a product where the final finish can make or break its acceptance. In some cases it can be as difficult or more than mirror polishing. As you tend to see the grain finish through the top coating on an extrusion the margin for error is much smaller. If the finish is not even or straight it will at minimum mean rework or possibly rejection. When you apply the grain you have to be careful not to over round any profile and go just the right depth with the grain. Too shallow and the top coat fills it in and it vanishes, but too deep and coating ends up thin in places and the grain is too pronounced. With the cost and headaches involved with top coating extrusions rework and rejection need to be avoided.
Some of the most common questions.
I thought I would share some of the most common questions I get and the related answers. This will not be a deep dive by any means but rather a few of the most common.
When to automate or how to improve retention?
Automating a finishing process is one of the more complicated things you can take on. When it comes to finishing the definitions tend to be more in the eye of the beholder. There is not one clear standard for finishes and in some cases the end user will confuse all manner of words. It is not uncommon for companies to say they need to polish something and when you dig a bit deeper you find they need a standard #4 type grain. To them that is polishing but to someone else it would not be. This is what complicates finishing processes the most. With bending or cutting the specs and tolerances are more clearly defined for example. The labor consumed by finishing makes it a prime candidate for automation. Being able to free up 3 to 5 people by automating finishing is common and it allows the labor to be moved to other areas of need. It is also an area that tends to have poor retention as it can be some of the dirtiest work in the facility. You can gain repeatability and more consistency as well as speed while reducing labor needed and improving retention.
Well here we go “the salesman” trying to pitch me his machine above the others, right? Well no, we want you to buy the machine that has the most impact for you and your business. You may not believe it but I have advised plenty of people that one of our machines is not the solution to their problem. Selection of the machine that is going to have the most impact on our business and our bottom line is always a challenge. Whether that is a new laser, punch press, brake or a finishing machine.
More of the basics
After touching on the difference between polishing, graining and bur removal I wanted to give some information on how each is done. I do not intend to go too far but rather the basic how and why for each. As with all things there is often more than one way to do anything. This is just pulling from my own experience of over a decade and what others have shown and taught me as well.
