The low end of the market is full of machines that are totally not suited to production work. This looks like an example of a machine that is built to work under very little load on the cutting head ie.. laser cutting and 3d printing and not hogging of guitar bodies with a decent spindle . To say this can cut guitar bodies all day long would be a lie, however if you take very shallow cuts it might do a good job of one or two hobby projects it would just take you 10 times as long as a proper wood working cnc.
