Hello Leo and fellow CNC producers,
I would like to recommend the BlueElephant machine for those who are looking for a cost-effective option that comes with standard generic parts and a sturdy build. BE is one of the biggest machine producers in the world and can produce ANY type of machine and customiz it to your specific needs. Compared to a German machine, BE costs only 15% of the price, even after container transport and import taxes. You can purchase approximately 6 BE machines for the price of 1 German machine.
After conducting a multi-year study comparing many Chinese producers and their specifications, I can provide advice on which parts to choose and technical advice if you give a referral to BE using my name. The machine I purchased from BE has a CE certification shield, and they provide basic electrical schematics. However, you will need to connect all pumps, extraction, and compressor yourself. It is recommended to have an expert check your wires and wire thicknesses to ensure everything is properly connected.
BE provides support directly on a WhatsApp group of factory floor engineers and even gave me a live video call to change a setting in the control computer. However, keep in mind that in Chinese culture, they may not say “no” and may avoid answering a difficult question instead. But no hard feelings, you need to communicate as simple as possible and they are happy to answer the next after. BE sends spare parts for free if under warranty or at a significantly lower price than what you would pay in the EU. Although they cannot come to your door to install or fix, they do have resellers in some countries that can sell you a standard machine and come to your door.
When considering the quantity of use, it’s essential to estimate your main purpose for the machine, maximum electricity connection, and how much space you have in your workshop. I recommend staying away from self-made or very slow machines like Maslo, as a WikiHouse can have up to 500 sheets of plywood, which can be costly and time-consuming if your machine is slow or under-equipped. You don’t want to risk of failure or expensive complications due to cheeping out on the machine.
For those who want to produce more than a few houses and have a big enough workshop, I suggest investing in an automatic loading and unloading system for plywood sheets. But this limits general use with blocks of wood thicker than 6cm. And @Leo_098 this will stil fit in your budget.
A strong vacuum table, preferably with multiple pumps, is essential, but keep in mind that you will need a capable electricity connection for it. The frame of my BE machine is double the size of normal machine and made of welded iron, which is absolutely sturdy and doesn’t shake or deform. With the whole installation of tables and accessories, the machine takes up 10x5m floor space, and you will need about 4 times that for a workshop.
With 2x 11kW vacuum pumps on the table holding down the sheets, 2 pressure rollers on top for holding down support, I can cut with an 8mm compression router bit at 24,000 rpm at about a 7m/min feed rate, cutting 18mm thick plywood in one go. For an average WikiHouse sheet of 40m cutting distance, with engraving numbers, drilling, and pockets, it takes me about 10 minutes to cut a sheet. More straightforward sheets take less time (5 min), while very complex sheets [full of bow ties] may take longer (25 min).
I hope this information helps those looking to purchase a CNC machine for plywood house production. If you have any questions or would like further advice, please don’t hesitate to reach out to me.
