I have been offered a job cutting wing struts out of aluminium I have a large cnc router with out coolant. what is the max depth people think I can cut and what speed do people think will be ok to use with out coolant.
i know coolant will be best to use. i don't know at this stage how much work I will be doing, so not going to invest in setting up coolant pump and gutters on machine unless its $1000`s of dollars of work
any suggestions will betaken on board
