How much does CNC machining cost per hour?

Usually, if it's precision cnc machining like Swiss style machines for example, it's not an hourly rate. You would normally talk with the customer and bid a price on it, which is like a lump sum for the whole job depending on complexity, material, 2nd processes, etc. So if you tell them two weeks and it goes over, it's your loss. It's generally easy to judge it by the machine, if your Tornos is banging out 120 parts an hour on something small for 45 cents each, or is your machine making 20 parts and hour at 55 dollars a piece?

Most machine shops would love to work on an hourly basis because they know what they need to make an hour to make money. In the Midwest, if you can make $50-$60/hr on your mid-range CNC equipment, you are making money. As such, this is the type of price you would be charged if you ask for CNC time on an hourly basis. More expensive machines (e.g 5 axis) command higher rates.
