If you want machine tools for commercial work you need to stop messing about with hobby machines and starting looking at industrial machines. They will have the power, rigidity and accuracy to make consistent parts over production runs.
The Wabeco is likely to be the more accurately built of the two machines but as it is of much lighter construction ( almost half the weight) than the Opti you will not be able to take as large a cut with it. As you want these machines to earn you money the Wabeco will make your profits less or your selling price a lot higher as it could take twice as long to machine a component due to the smaller metal removal rate.It's down to you to work out the economics as to sale price vs accuracy
When I was looking after a sub-contract machine shop in London the maxim was "If it isn't coming off blue then it isn't making any money!"
I agree with Jo trying to help the OP is a complete waste of time NO BLUE CHIPS for you.Cheers Dan
The machines belonged to a good friend of mine that spent the last couple years preparing for retirement. He paid off his bills, collected tools and set up a great shop. Then he dropped dead 2 weeks before his retirement date.
For manual milling I'd look at Bridgeport Series I, or one of the clones. Depending on production quantities a CNC mill might be better, in which case I be looking at one of the smaller Haas mills. Neither are big machines, or high end, but should meet your requirements.Andrew
As Andrew says and I said in your other thread in this day and age for production and batch work CNC is likely to be the best way to go. Haas Mini mill or a Syil X7 or if space is at a premium the Haas compact will fit through a standard doorway but is a bit more expensive. They will cost more initially but you will be able to produce parts faster and with good repeatability so volume of sales should be higher and capital outlay recovered.Even the lower end hobby CNC machines are more solidly constructed than similar sized milling machines, as an example my KX3 mill is about the same size as the Wabeco yet weighs twice as much as the castings are far more substantial to damp out vibration and make the machine more rigid, Andrews machine will be more substantial again being a bit higher up the ladder. Some owners even put them to use for production work but for the difference in current cost between a KX3 and a Haas I would go with the Haas or Syil with a tool changer if I wanted to earn money with them..
