Description
A recent model Knee Mill made by the Bridgeport company. This is the gold-standard small shop manual milling machine in the US. Most other mills of the same size are direct copies of the bridgeport design. This particular machine is a Series I, J-head with a mechanical variable speed drive. The machine has a power quill feed built into the head, in addition to the additional equipment listed below. This machine is capable of facing, surfacing, drilling and slotting in materials ranging from plastics to mild steel. Harder metals may be cut if special cutters and coolant are available. This machine is not equipped with CNC controls, consequently curved paths are limited to circular arcs. These can be cut on pieces that can be mounted on the 8" rotary table or approximated to a desired precision using the simple or smooth arc functions of the DRO.
This tool may require training to be used correctly.
