Desktop CNC from China. cnc milling machine from china

The topic is quite specific, but I was going to post a similar brief review for a long time, and they often ask in messages.
I will give a list of the main components for CNC homemade products: milling cutters, printers, engravers, etc., using the example of a homemade mini-milling cutter

I have long been interested in the topic of CNC and related information and monitor the cost of "desktop" devices on the market, for example, CNC1610 or CNC2418. There were already a couple of reviews on the first one on the muska (reviews on the CNC1610 from and from). There has not yet been a review on the CNC2418 here, reviews on other resources are not comforting. If anything, the numbers in the title are the working area of ​​the machine. Although knowing the Chinese comrades - this is rather the size of the machine.
But seriously speaking, the market value of such assembly kits is greatly overestimated. I'm not ready to pay under $300 for a similar set. But to assemble it with your own hands is three times cheaper - please! For comparison, in the photo on the left is CNC1610, on the right is CNC2418. They like to hang an additional laser head on the latter.


By the way, having a similar desktop CNC machine, which will always be "in the wings" in the manufacture of printed circuit boards and small crafts, is a big plus for a home craftsman.

So, at one time I was puzzled by the assembly, and even assembled it. Now I am assembling from profile 2020. The set of components is approximately the same for both plywood and CNC2418. I will try not to miss anything and give a complete list of components.


As a rule, you need to buy a set of guides: rails or polished shafts, lead screws (most often T8, GT2-6 belts can be installed in laser machines, it is not desirable in a router), Nema17 motors, spindle (most often a DC motor type RS775 or more powerful) and various small things such as bearings, calipers, hardware. The issue of electronics is separate: someone uses Arduino Nano / Uno + CNC Shield boards, someone Mega + Ramps, there are options for more serious kits for Mach3.

I quote prices from banguud, because I'm tired of buying 1 lot from different sellers with Ali and waiting for a bunch of parcels arriving at different times. Prices comparable to Ali, somewhere cheaper, somewhere more convenient to apply. As a result, I received one large parcel with a kit. I also give keywords for self-search if you need to find something similar on Ali or Tao.

Now in order. Received a parcel of various kits for machine tool mechanics.

Polished guide shafts.
Linear Shaft (Rod). Still found optical axis(polished axle). There are 5-6-8-10-12-16-20 mm. The current diameter is 8 mm. For 16-20mm it is better to use round rails like SBR16 or SBR20 as they have support. Shafts of different diameters are used, for example, in the Ultimaker printer (6-8-10 mm). 12mm shafts - in the Z axis for the ZAV 3D printer.
In the photo 6 mm, 8 mm, 12 mm.


Shafts 8 mm. I took a part in size (they are chamfered), I cut a part myself

There are shafts from 5 mm to 12 mm and lengths 300-600 mm


Individual lots are slightly cheaper. I try to take the length either in size or much more in order to independently cut 2-3 pieces of the desired size from one shaft.


Here is a cut with a miter saw. It is desirable then to clean, chamfer.



with lengths 300...500 mm
with lengths 100…350 mm
Comfortable when sized. Yes, and from time to time they make promotions for different lots, if you don’t rush to assemble the machine, you can save money.

Lead screw T8 ( Lead Screw T8, screw T8 Nut)

Considered in detail in, a screw with multiple threads. It is better to take immediately with a nut.


If sawing, then in addition it will be necessary to buy more brass nuts

(Pay attention to which warehouse you choose in the store, the price is different).


from 100 to 600 mm
I usually take more, plus one nut. I cut to size, the rest goes somewhere else


screw T8 on the end surface ( Flange Bearing KFL08)
T8 screws on the profile Mount Bearing KP08



Profile accessories
2020 Corner Bracket
To assemble a machine type 2418, a minimum of 16 pieces will be required. Take with a margin)))


for profile 2020 (slot 8mm) 100 pcs. It's also better not to be trifled. One hundred pieces will scatter in a moment, especially considering that they can attach anything to the profile. To order: T Nut M4 (there are M3, M5, for a groove of 6 mm)


And here is the 2020 profile itself. This is a structural one. This is probably the cheapest option, since a profile from China will cost more, and there is a limit on the maximum length of parcels in Chinese mail (500mm).
I bought a set of profiles cut to size for 2418 right away.

Under the spoiler, the dimensions of the segments, tips for ordering.

There are two options - uncoated profile (cheaper) and coated (anodized). The difference in cost is small, I recommend coated, especially if used as roller guides.

Select the desired profile type 2020, then enter "cut to size". Otherwise, you can buy one piece (whip) for 4 meters. When calculating, keep in mind that the cost of one cut can be different, depending on the profile. And that 4 mm is laid on the cut.

Enter the dimensions of the segments. I made machine 2418 a little larger, these are seven pieces of 260 mm and two vertical pieces of 300 mm. Vertical can be made smaller. If you need a longer machine, then two longitudinal sections are larger, for example, 350 mm, transverse ones are also 260 mm each (5 pcs).


We confirm (must be added to the nesting map)


I usually take the leftovers (small pieces) for something else, for example, a holder for a 3D printer spool.


The profile is obtained at 667r along with the cutting service.


Delivery is carried out by shopping mall, you can calculate the cost using the calculator, since you know the dimensions of the profile, the weight is very well calculated in the cutting chart. Plus "pick up the goods from the supplier." That is, the cost to me before Tula came out 1450 (30 kg of profile for different purposes). Delivery by business lines will cost less, about 1000 rubles.

Can be picked up by self in Moscow.


In one place there is an office, a warehouse and a workshop where the profile is cut to size. There is a showcase with samples, you can evaluate the profile. I was just choosing a profile for the SBR20, it has seats through 30 mm, this is a profile, 3060, 3090. Initially I wanted 4040, rummaged through the assortment, I realized that even 6060 is better.

But the profile "in place"

About a large machine is a separate issue.

Well, except that I forgot to specify about the spindle. These 1610 and 2418 machines use

Milling machines are machines classified according to the type of material processing (metal, plastic or wood). Milling machines are designed for processing metal or wood with a milling cutter of both flat and shaped surfaces, rotating bodies, gears, etc. The cutter, while fixed in the machine spindle, performs the main (rotational) movement, in turn, the workpiece, fixed on the table, performs translational or curvilinear movement.

Milling and engraving machines are controlled both by manual, automated methods and by means of the CNC system.

The main movement in milling machines is the rotation of the cutter, and the auxiliary movements are the translational movement of the cutter and the workpiece, they are necessary for the preparation and implementation of the milling process.

Application of CNC milling machines

CNC milling and engraving machines are most widely used in the production of furniture, souvenirs, milling and engraving of curly wood elements.

CNC engraving machines are designed for processing wooden flat surfaces. They implement the processing of flat and three-dimensional (3D) workpieces. Any image is applied to a tree according to a program sketch. Delivery of milling machines of various types, with and without CNC, from China has been carried out by our company for more than a year.

Delivery process of milling equipment from China

If you want to deliver large volumes of milling machines from China yourself, you will encounter certain difficulties. The first one is related to the dimensions of the equipment. If the dimensions of the machine are larger than allowable for rear loading, a side loading vehicle must be provided.

The second problem is that there is always a need for equipment for loading and unloading machines, such as loaders or cranes. In addition to everything, the delivery vehicle must have the appropriate dimensions. If the dimensions exceed the maximum allowable, then special transport is required for transportation.

As for the issue of delivery, as a rule, people who deliver engraving machines from China on their own have difficulties with the process of preparing documentation and customs clearance of the delivery. Factories producing machine tools and equipment, of course, provide all the documents necessary for import to Russia. But customs representatives often change the TN VED code in the process of declaring. This is due to previous deliveries of such equipment, which may increase the amount of customs payments, delay the release of a consignment and provoke a customs inspection. A high reputation at the Altai customs allows the specialists of STA "SibirTransAsia" to minimize the risk of increasing customs duties and customs clearance time.
