The milling blade is configured to extend radially outward from and inwards toward the cutting block. One or more links may couple the milling blade to the tool body to cause the milling blade to move radially relative to the cutting block when the cutting block moves radially relative to the tool body. The milling tool may be used as a dual string section mill to remove any of an inner casing ...
· The OEDK recently purchased a new 4axis CNC Mill, and I wanted to work out a way to perform the ENGI 210 Final project using that machine. The machine, a fully enclosed Tormach PCNC 770 with a 10 tool automatic tool changer uses a flood coolant to increase work speed. The drawback however, is that you really should not use wood in the machine because it can get impossible to .
