Hello, in my workshop we have a Haas VM3 we machine some pieces utilizing G10 FR-4 GLASS EPOXY COMPOSITE LAMINATE MATERIAL We machine it with coolant and Carbide tools, My question is: ¿What is the best way to machine this material? (to get better tool life and faster machining times) also ¿does it really need coolant? My guess is that at a higher feedrate and no coolant should work great but the machinist is not agreeing, any advice is welcome.
