Sleeping car extended top (can be processed with drawings)

Top notch is a type of machine tool component that has a small outer diameter, fewer interference knives, and is suitable for high-speed and moderate cutting. It can support parts with complex end faces and parts that do not allow center holes. It mainly consists of a top pin, clamping device, housing, fixing pin, bearing, and core shaft. One end of the tip can be the center hole or the inner hole of the pipe material, and the other end can be a spherical or conical part with a top surface. The tip is fixed by a clamping device. When the part does not allow or cannot be drilled with a center hole, a clamping device can be used to directly clamp the turning machine.
