6. Operating the Lathe
This section covers the fundamental procedures for operating the South Bend Nordic 15 lathe, including startup, speed and feed selection, and engaging feed motions.
6.1 Start-up and Running In
Before starting, ensure all safety guards are in place and the workpiece is securely mounted. Follow the recommended start-up sequence, allowing the machine to run briefly at low speeds to ensure proper lubrication and function.
6.2 Starting, Stopping, and Reversing Direction of Rotation
Use the designated controls to start and stop the spindle. The direction of rotation can be reversed using the appropriate lever or switch, typically located on the headstock or control panel. Always ensure the spindle is fully stopped before changing direction.
6.3 Selecting Speed and Feed
The Nordic 15 offers a range of speeds and feeds. Consult the speed and feed charts, usually located on the headstock, to select appropriate settings for your material and tooling. Adjust levers on the headstock and gearbox to achieve the desired speed and feed rate.
6.4 Longitudinal or Cross Feed Motion
Engage the longitudinal feed for cutting along the length of the workpiece or the cross feed for facing operations. Ensure only one feed motion is engaged at a time unless specifically required for a combined operation. Use the feed engagement levers on the apron.
6.5 How to Use Thread Chasing Dial
The thread chasing dial is essential for cutting threads accurately. It indicates when to engage the half-nuts to ensure the cutting tool re-enters the existing thread groove correctly. Follow the specific instructions for your thread pitch and lead screw combination.
