A manual milling machine cuts flat faces, slots, steps and keyways with a rotating multi-tooth cutter while the operator moves the table. Vertical, horizontal and universal types are still widely used for tool-room work, repairs and simple batch jobs.

Manual mill or VMC?
- Manual mill: no programming, good for quick one-off jobs and repairs
- VMC: faster, more accurate and repeatable, handles complex shapes and batches

Questions
- What is a DRO on a milling machine?
- A digital readout that shows the table position, so the operator can set sizes accurately without counting handwheel turns.
- Can a manual mill cut gears?
- Yes, with a dividing head and form cutters, for small quantities. Batches are cut faster on gear hobbing machines.
