Adding more 2D shape ideas to our online shop, today CNCROi.com will review the production of two wooden royal crowns out of MDF.
CNCROi.com is able to cut just about any shape at any resolution using any material for any application you have a need us to fulfill. In this case, we’ll transform scrap quarter-inch or 6 mm MDF into royal crowns fit for a 2D king or queen.
Although we could have made this out of anything, from stainless steel through Corian or wood veneer through laminate, MDF is a quick way to test out a design that we do with some of our customers in order to proof a design before going into real production.
We are CNC laser engraving these MDF royal crowns first to create additional accuracy in this design, creating optimal tool pathing and processes is half the job when it comes to making accurate results for our customers to spec.
For instance, cutting these crowns first and then engraving them may predispose them to moving ever so slightly, so you’d see a very light deviation to the left, right or overall in the design. This is avoided by engraving first then engraving these royal crowns.
This isn’t the only thing to keep under consideration when it comes to using our Austrian dual-sourced industrial wide-format laser. We can move the head of this laser incredibly fast but going too fast means the laser doesn’t have time to engrave deep enough into the base material.
Another factor that must be carefully balanced is power to speed ratios, using too much power while going too slow means we are cutting instead of engraving. As a result, we do lots of material testing when it comes to materials we aren’t familiar with or the customer requires a specific spec on a material that we have worked with previously.
The laser light blurring you see in the video and these photos is just some smoke that built-up on the under-surface of our protective acrylic laser top. We had just done a big production of custom polycarbonate parts and the smoke built-up on the covering and needed some cleaning so our camera was having trouble focusing on the proper areas.
After the custom engraving process was completed, our laser now cuts out these wooden royal crown shapes, the engraving was accurately done and now, the cutting will match perfectly to the cutting.
What’s really great is that due to the fact that CNCROi.com produces these 2D shapes realtime, they can each be individualized or personalized however you wish. For instance, each crown can be completely different engraving and cutting wise and additionally, we can add names, dates and any other information you wish.
What’s also unique about our industrial machine is that it’s made for industrial use, meaning it can run 24 hours a day, 7 days a week and all year! This is an important distinction, as it means that we can meet tight deadlines or massive production runs quickly, precisely and efficiently when the time comes.
The steps you’ve seen thus far are essentially the same regardless of the material we are CNC laser engraving or cutting. CNC processes don’t really deviate that much regardless of whether it’s done with a waterjet, plasma cutter or any other CNC machines short of a 3D printer.
After one custom royal crown is liberated from this quarter-inch or 6 mm MDF, it’s time to cut out the second one. The importance of these steps can’t be exaggerated enough, as each step leads to another step until the final product is created for our customer.
The fire you see during this custom laser cutting is also real, and yes, it is a hazard but when I bought this Austrian machine, I knew what our custom fabricated laser needed to safely do projects that most shops wouldn’t.
We have all the bells and whistles within our laser, from the premium Trotec Speedy 400 flexx with both a fiber and CO2 laser source to compressed air, extraction systems and a whole lot of other things. As a result of all of this, we are able to produce consistent results for our clients.
You can now see the results of this there is very little smoke that’s left on these royal crowns, for actual production, we’d generally mask the surface so that very limited sanding would be required.
Let’s take a look at these MDF crowns a little closer. For instance, you can see, even in these photos, the fantastic engraving that has a consistent depth in these pictures.
Additionally, you can notice the very minor material variances in density across the surface of this quarter-inch or 6 mm MDF.
You can see lots of our custom shapes in our Shapes Library and of course, send us your files and we’ll make whatever you want for your use as well. Contact CNCROi.com right now!
