Final answer:
A universal-type milling machine has a horizontal spindle and a worktable that can move in three different directions, giving it its distinctive multi-directional machining capability.
Step-by-step explanation:
A universal-type milling machine has a horizontal spindle, and the worktable has three movements. Option C) Universal is the correct answer to the question. Universal milling machines are designed to perform a variety of operations with various angles and directions of feed possible due to the multi-directional movement of the worktable. This is in contrast to a horizontal milling machine, which typically has a worktable that can move in two axes (left-right and forward-back), or a vertical milling machine, which has its spindle oriented vertically and the worktable that usually moves in the same two axes. Meanwhile, a rotary milling machine is characterized by a worktable that can also rotate, hence the name.
