ABSTRACT:
A milling apparatus for forming a key bit includes a base, and a key holding member positioned in front of the base. The key holding member includes an upper clamping plate and a lower clamping plate, which are adapted to clamp a key blank therebetween. A carrier is mounted movably on the base. A hollow body is mounted slidably on the carrier, and has an interior chamber and a concave front face unit which is formed with a cross groove. The cross groove has a vertical section and a horizontal section which is adapted to be aligned with the key blank that is clamped between the upper and lower clamping plates of the key holding member. A milling cutter is mounted rotatably within the interior chamber in the hollow body, and extends into the vertical section of the cross groove in the front face unit of the hollow body. A resilient unit biases the concave front face unit of the hollow body to contact the upper and lower clamping plates of the key holding member, thereby locating the upper and lower clamping plates on two sides of the horizontal section of the cross groove. A waste collector is adapted to suck metal waste from the interior chamber.
