![]() I know there are other manufacturers of quality CNC Routers and I hope people will chime in and provide some useful information. I do own a ShopBot and I run another ShopBot at CNU so you can see I am a real fan. I can't offer much in the way of advice concerning a comparison between ShopBots and other manufacturers.

I give you my thoughts on those if you'd like.įull disclosure: I work in the industry for a company that offers CNC routers from around 20k to over 200k. Again look upmarket, what do the most respected machine builders use?Īlso compare spindles, and controls. A loose hold on the handles impacts your quality of cut. If your want a nice cut you white knuckle the handles. Think of it as your grip on your hand held router. "Profiled rails" use an interference fit. ![]() An ability to preload the bearings is key. Things like squareness and parallelism are locked in at the factory. Welded is prefered because the stiffness is greater and accuracy is machined into the frame. bolted together or welded into a single piece. Next point of comparison is how is the frame assembled. ![]() The downside, for the machine builder, is that the equipment for cutting steel frames is more expensive, and slower that aluminium cutting machines. Steel is more temperature stable than aluminium and is a better at vibration dampening (from cutting). All the upscale machines, and I'm talking 150K and north are steel. First compare the frame, steel or aluminium. This is a very non partisan way to grade machines, and the service life. Start by a gereral comparison of construction methods and components. All machine builders today are reputable so it is a matter of trying to seperate the sales talk from the fact. Every machine maker has an idea of where, on the price performance curve, they want to target.
