This is the build log of the housing I built for my Shapeoko 3 desktop CNC machine from Carbide 3DIf. You would like to learn more about some of the technical aspects of the shell and the machine itself, please go through my blog: Please check my youtube channel: the idea behind this building is to create something that my machine can install inside and it will surround all the dust and most of the noise.
This is an ongoing project that has been around for some time and started shortly before the delivery of my Shapeoko 3 desktop CNC machine.
With my previous CNC, Shapeoko 2, I pieced together a wooden case with a polyester side and a removable front panel.
It works in controlling dust and isolating some noise, but it doesn\'t look much.
I want to get things done this time.
When I started planning this building, I thought that the two architectural techniques were the most effective and beautiful approach.
The first method is to use the length of the aluminum extrusion to construct the frame, fill the gap with an insulating board, and then clamp with plywood or medium fiber board.
Alternatively, I can buy a unit where the machine can be placed in it and make proper modifications to it as needed to increase the sound insulation effect.
I have chosen the latterSteel frame shelving unit which can be purchased relatively cheaply and can produce rigid structures with only a very small number of components, only two 18mm mid-fiber boards that can act as top and
The 3mm steel provides a sturdy structure that allows easy installation of parts through drilling and tapping.
The two main goals I would like to achieve with this shell are to include all the dust and debris in the unit and provide noise isolation at maximum speed which is a pretty irritating sound profile, when the machine runs on longer jobs, it would be nice to be able to stay in the same room without having to wear hearing.
To achieve this, I decided to suppress the Poly with noise-
In the middle, there are two polyurethane foam with a 6mm medium fiber board.
I used about 60mm of the foam in the wall cavity and combined the layer with the spray on the contact adhesive.
After the insulation foam is installed, the wall cavity can be closed with a 6mm medium fiber board, the sides are kept in the appropriate position, and the top and bottom are matched with more spray glue and friction.
The rear of the panel is assembled in almost the same way, but fully mounted on the outside of the steel frame to maximize the space inside the housing.
The aluminum frame at the front of the unit is definitely the most beautiful and functional feature of this building, and it is needed for several reasons.
It will provide a smooth and perfect square surface to mount the polycarbonate door onto the housing, but more importantly, it allows the spindle installation of the Shapeoko to extend itself over the base of the cnc machine.
The size of the aluminum I use is 50mm x 100mm x 3mm.
The extra 100mm at the front of the outstretched housing allows the spindle to mount the gap.
Fixing the aluminum tube extension frame to the front of the housing allows Shapeoko to maximize its working area without having to keep the door of the housing open so that the spindle holder does not touch them.
In addition, you can also see in the picture that the drill bit itself hangs on the edge of the Shapeoko work area, so the aluminum tube frame also allows the construction of an extended work holding table, in this way, Shapeoko can definitely maximize its cutting capacity.
I will build and expand the workbench in the near future.
Connecting the aluminum frame steel frame requires me to drill holes in the front of the aluminum frame so that I can pass the bolts through the aluminum frame and then add nuts to create a secure fixture for the rigid frame steel frame unit.
I could have simply drilled the back of the aluminum pipe and then bolted it from the inside of the steel frame.
The problem with this is that since the aluminum is only 3mm so the thread is not particularly strong, I am worried that I will strip the thread if I try to tighten the bolt.
Finally, the 3D printed plastic cap I designed makes the overall frame more industrial aesthetic.
The next key feature I aspire to include in this version is to keep all airbourne dust in the machine.
Even if the door is closed, due to the fan in the Dewalt spindle, some dust can still be avoided as the air inside the housing is thrown around.
So in order to achieve the negative pressure inside the machine and prevent the dust from leaking through the gap, I added this entrance, which receives the hose of my vacuum cleaner and installs it smoothly but tightly.
The door of the shell is definitely one of the most challenging aspects of the building.
Because the doors will be set inside the frame and keep the finish clean and flush, they have to be completely cut . . . . . . I do have some room as I intend to leave a gap at the top to allow air to flow in to help the vacuum create negative pressure inside the shell what I want
I used 10mm of polycarbonate in the local workshop and had a sheet that was not needed.
This is a fantastic plastic, very crushed
Used in bulletproof cups.
It will certainly protect me from any tool damage or anything that could happen inside the shell.
I took a break as an interesting little test
Cut polycarbonate and pat a front
The charged air rifle, it stopped the bullet, so I thought it would stop a broken tool on the router!
Anyway, I cut it into small size with a saw and track, I didn\'t cut it perfectly, but it was enough for his app.
The only unreliable cut-out is the cut-out that divides a panel into two doors, which leaves a slightly larger gap in the middle of the top than the bottom, but I can cover it if needed
The last step at the front of the shell is to connect the handle.
These are very bulky ABS machine shop handles specially designed for doors in industrial environments.
These are simply connected with two large bolts via a polyester.
After that, I connect some LED strips to the top of the case and set them to Blue White.
I like cool (
Such as temperature)
Video and photo effects.
I also installed a magnetic buckle to close the door.
Start working on some projects with this machine now! ! !
