MSLG Unité d'Étude des Engrenages de Tour

The Unit to Study Lathe Gears, "MSLG", represents the gears of a typical lathe in a machining workshop, including: a main adjustable transmission gear, one Norton gearbox for the machining of specific threads and pitches, a pinion switching gear and a reverse rotation gear.

The part to be machined is represented by an exchangeable cylinder and the cutting tool by a marker. This system allows a dummy test of the machining of the part, the thread pitch and the grinding produced, with the tool post carriage always moving longitudinally.

The unit works using a movable main shaft with three driving pinions of different size, which is driven by means of a graduated handle, and allowing the spindle to change speed. The movement produced in the main shaft is transmitted to the spindle by a gear mesh enabling the reverse rotation. At the same time, the spindle is connected to a Norton gearbox, which conveys the movement to the guide screw, enabling the production of threads of different pitch and the automatic forward movement of the tool post carriage. In parallel, the unit also has an operating lever for the tool post carriage.

Thanks to the lathe gears protective panel, the unit is totally visual and completely safe.
