Cheap large Routers

[Boyan Silyavski]

It has at least one ton of metal, probably around 1.5-2. My machine has mere 750kg which cost me here around 1000euro. Also i had to weld much more as i coudnt obtain nor manipulate at home that kind of steel profile they are using, which is enormous. That said its obviously better to use large steel profiles, machines and means to manipulate them, to have space to store and larger machine sou you can machine the rail surfaces.

All rails are Hiwin so thats also not cheap.


As i said, not a Ferrarri / i like to think about my machine like that true or not/ but pretty damn good.

Well according to the listing, the net weight is 1500kg.
Looking at the photos, to me the metal doesn't look that thick, so at most I'd guess the basic metal work is somewhere around 1000kg. Having just had a quick look at bulk steel costs, the price guides I can find are in the region of 3-500USD per tonne/ton.

As you mention, the big problem is handling the large sections. If you have the capabilities, and buy enough steel to get it at near market prices, the cost of building multiples of this size of machine is far less than what most people would think. Once you've worked out any teething issues with the manufacturing process, it's as simple as cut, weld, paint, assemble.

Plus if you don't have to worry too much about support, that's part of the cost you can greatly reduce.

I've converted similair chinese machine and the boxsection was mere 2mm and felt like tin can. However the Frame rails which rails and R&P were mounted on was Cast steel which was machined. It was thin brittle nasty shity casting which snapped if you looked at it funny. Couldn't remove bolt without it stripped threads.

The machined surfaces were so badly machined may has well not bothered. The bed supports which spanned between castings were made from U section and not very strong or straight.
All drilled holes looked like they'd been done by blind man who'd had 10 pints.!! . . . . Z axis was joke and it's now door stop.!!

Yes they are cheap but they need plenty of fetteling IMO which is beyond most people. The electrics are mostly junk and to have reliable machine will at some point need replacing or upgrading so not saving anything there really. This just leaves the main components like linear rails R&P.

I'm with MC in that cost of steel is small in the grand scheme and far better frame could be made for not lot of money. While It's not possible to build same machine cheaper but certainly is possible for DIY builder to build one better for same money.

Here you go lads have look under her skirt and see exactly what I mean poor workman ship and that looks lot better than others I've seen and the one I converted.!!

Got to admit it's poor workmanship! Castings are also soft, and skimming the gantry looks like it's been done with a fly cutter in a grinder

Disappointing insides, i have to agree. i looked at the link so they have the same internal bracing.

There was a promising bar beneath the rails, but if as you say sb machines that with angle grinder, then no point.

Ok, i can sleep better now :-)
