Speed Adjustment
| |
|---|---|
| The speed control on the Bridgeport mill. |
The spindle speed is adjusted manually with the crank on the right-hand face of the headstock. Only adjust the spindle speed when the spindle is turning!
A range-control lever on the left side of the headstock switches between "Tortoise" and "Hare" speed ranges. Change the position of this lever only when the spindle is stopped! The spindle may need to be rotated manually when changing the speed range to allow the gears to mesh. The direction of the spindle reverses between the two modes (note the directions the two animals are facing) so the power switch (top left) also has two positions.
This machine has variable-speed motor drives (Not CNC) on the two axes of the table.
Manual Draw-Bar
This machine has manual tool-changing with a wrench.
