Using your Jet 321501 Large Spindle Bore Lathe is quite straightforward. First, make sure it's properly plugged into a 230/460V, 3Ph power source. Then, you can start adjusting the spindle speed according to your project, which can range from 42 to 1,800 RPM. When it comes to threading, the Universal gearbox allows you to easily switch between inch, metric, diametral, and module pitch threads without changing gears. Just set the right parameters and start working. For cutting operations, the one - piece cast iron base helps absorb vibrations, so you can make heavier cuts. But be careful not to overload the machine. As for maintenance, regularly check the lubrication of the carriage. The one - shot lubrication system is there to help, but it's still a good idea to make sure everything is well - oiled. Also, keep an eye on the bed ways, which are made of wear - resistant cast iron. Clean them regularly to ensure smooth operation. If you're working on large - diameter pieces, use the removable gap feature, but make sure the piece is properly secured. And don't forget to use the five - position automatic carriage stop to boost your productivity. Lastly, if you encounter any problems, refer to the industry - leading two - year warranty that comes with your JET Lathe.
