Hi everyone. I have sourced and cut various makes of MDF now and i am having the same problem with all of them, and that is the edges are furring quite badly. Is there a type of MDF i can use that leaves nice crisp edges? I need to stock 4, 6, 9, 12 and 18mm. I am aware that spindle speeds etc can cause the furring but have also tried slowing right down and speeding up to try and get round this...but no joy. I have used a straigh twin flute bit and a single flute upward spiral but am getting the same results. I am fairly new to CNC and everthing i do is a bit trial and error but need to get this sorted. Can anyone help me?....please? :) Sean
