A lathe is a machine tool that rotates the work piece on an axis to perform various operations such as cutting, sanding, knurling ,drilling, facing, and turning. It does this with a stationary tool that is applied to the work piece to remove material. The lathe will create an object that is symmetrical about the axis of rotation it was rotated about. It is useful for creating flywheels and other circular parts. There are two lathes available in the machine shop and there are some small differences between them, namely the start/stop procedure.
- Spindle - The part of the lathe that rotates
- Chuck - Clamping device that holds the material
- Tailstock - Adjustable mount that is used to support the of the material, drill holes, and ream holes.
A common difficulty with using these lathes is activation. The images below demonstrate the differences between Lathe 1 and Lathe 2, please refer to the video below for more information. Note that the activation lever on Lathe 1 needs to be pulled out before being moved up and down. It also has a neutral position. The lever must be in neutral position for the machine to turn on. If this happens, ensure that the lever is fully in forward or reverse. It is safer to run the machine in forward because the chips will tend to fall down and into the tray rather than fly up and out.
Face a 1” aluminum bar down to 0.75”, drill a hole through the middle, and then ream the hole. Check out the image below to see what this should look like.
This video contains specific information for using the lathe in the Maker Hub as well as a basic overview of what will be expected in your live demonstration.
- Never wear gloves, long sleeves, jewelry, or have long hair down as all of the can get caught in the rotating portion of the machine.
- Make sure to remove the chuck key. Sounds simple but this is probably the most common mistake in the machine shop.
This machine requires minimal maintenance. Like all the other machines in the Maker Hub it is important to clean the machine of metal chips and any other debris after each use. Anything more advanced will be taken care of by Justin.
