Some years ago now I got a job as a CNC Operator, and from there progressed to a Setter, then a Programmer. In my current job I program, set, and operate a CNC Lathe with milling capabilities, producing mostly components for the oil and gas industry.
I would kindly disagree with the guys claim that it is easier, or you do not have to be as highly skilled to produce parts on a CNC machine compared to a manual machine. In fact, I would say that being a good CNC machinist is probably a MORE highly skilled job than being a manual machinist.
To be a CNC machinist you still need to understand the basic fundamentals of material removal, i.e speeds and feeds for cutting tools for cutting all different kinds of materials / selecting the best tool to carry out any particular operation / how to cure problems with materials not chipping or stringing up / tools cutting oversize / Also, when using a manual machine you can 'feel' when something isn't right, when a tool isn't cutting properly whereas a cnc will melt the tool before you realise that something isn't right, and actually learning how to program and operate these machines is not something that everyone has even the capacity to learn. Different people are good at different things, and CNC part production isn't for everyone. It is for people who are technically minded, preferably with some kind of engineering understanding or qualification. Small mistakes in this game can be very expensive. A guy in a place I used to work had a little lapse in concentration and crashed a CNC lathe. The bill for repair came to £30,000.
Also, CNC lathes are more expensive than you claim, more than a few thousand dollars. The haas lathe you show in your video is an automatic toolroom lathe, not a serious cnc lathe which would at least have a 12 station automatic tool turret. If you had 10,000 of your 'great inventions' to produce, I'm pretty sure you'd get sick of manually changing tools every minute or so.
A proper CNC Lathe or Machining Centre is prohibitively expensive to Joe Public. The cost of tooling for these machines is huge also, thousands of £'s. You usually need a decent size air compressor to run one as well, which isn't cheap to buy or run, and cnc's also use a fair bit of electricity.
If you want to learn how to use these machines, do a college course in preferably manual machining first to understand the fundamentals, then cnc machining, or try and find an engineering apprenticeship.
If you just have an idea to make something like the guy in the video says, you'd be better just making up an engineering drawing, and paying your local job shop to produce a prototype for you. If you then decide that your little invention is going to sell by the million, you'd better be pretty sure, 'cos you'll be looking at spending £70,000 to get yourself a half decent new CNC Lathe or mill, or £250,000 on a good one if you've got money to burn, and these prices are for a fairly small machine, for example a lathe able to turn components a maximum of 700mm long. You could go second hand and save some money but remember - you've got no manufacturers warranty, and you'd better hope it doesn't break down, 'cos I promise you they ain't cheap to fix.
If your part has turned features and milled features then you'll be looking at spending a minimum of £100,000 for a new machine, and that's a cheap Taiwanese machine, by no means Rolls-Royce material. We're not talking pocket change here.
And all this is before you think about tooling the machine up, or running it. And like I said, if you took the cheaper second hand option, you maybe got a half decent little cnc lathe for £25,000 or so, but you'd better hope it doesn't break down.
It is a good skill to have, and can be a fun and rewarding job to do, but it is prohibitively expensive to set up for yourself without large financial backing, or a big bank loan.
If it was straightforward to set up yourself, then I'd be working for my own company, not someone elses. But it isn't, so I'm not.
Don't let that put you off if you want to learn though, because if you find a decent company it can be a fairly well paid job.
