Having slower speed is important if you want to work on heavier materials so that you prevent breaking needles and threads. Also for the beginners of industrial sewing machine, it is very necessary to slow down the speed of machine.

Increasing the speed of a machine is often acted because operators are working with lighter weight fabrics and want a fast output. High speeds are often associated with the clothing or fashion industries where the same pattern is being completed continuously.
