Watch me use CNC milling to craft a long slot on a rectangular metal workpiece in this video. On a CNC mill, I machine a precise slot (50 cm long, 5 mm wide) into a lengthy workpiece, tackling the challenge of its extended size. Using a 6 mm carbide end mill at 3000 RPM and 0.1 mm/rev feed, I ensure a smooth finish with coolant. The process showcases stable clamping and vibration control for accuracy. Ideal for machinists and engineers, this CNC milling demo highlights the skill needed for long parts in machinery or aerospace. Join me to see how CNC milling transforms a long workpiece into a precision component!
