Common parts of the sewing machine are the bobbin winder, bobbin holder, presser foot, feed dogs, needle, and thread spool holder. The presser foot holds down the material. The feed dogs help the material move through the machine.

I don't know what you want to know about the mechanical parts? How it runs? How to clean and oil it? Most of that information is in the instruction manual. To find out the mechanical parts, go to the company webpage, then to repair/parts. Punch in the model # and you can usually come up with any part of the machine, the repair number and part numbers, photos/drawings, etc.
