The headstock is a cast-iron box inside, which houses the main working parts of the machine - the spindle and gearbox. At the right end of the spindle, a device is attached that clamps the workpiece, which receives rotation from the electric motor located in the left cabinet through a V-belt drive and a system of gear wheels and couplings located inside headstock. This mechanism is called a gearbox and allows you to change the speed.
