For a vertical mill that lacks an automatic table, what is the best technique for milling?

When milling on a vertical mill without an automatic table, the best technique is manual feed. Manual feeding allows the operator to have direct control over the movement of the table and the cutting tool. This is particularly beneficial because manual operation enables the operator to make fine adjustments to the feed rates and depth of cut, ensuring comprehensive control over the machining process.

Operators can intuitively sense how the material is reacting to the cutting tool and modify the feed rate or the approach to better accommodate variations in the workpiece material or geometric complexity. This hands-on approach can be essential when performing intricate milling tasks or working with materials that may require a more careful touch to prevent damage or excessive wear on the tool.

In contrast, other options, like using a band saw, are unsuitable for milling tasks as they are designated for cutting rather than shaping material. Power feed systems, while effective in providing consistent feed rates, are not an option here since the question specifically states that the vertical mill lacks an automatic table, which typically includes power feed capabilities. CNC programming would also not apply to a manual setup, as it relies on programmed instructions rather than operator control.
