    Default How normal is the noise made by decelerating from 2400 to 0rpm in a SL40?

    I normally only work with small lathes (max 250mm diameter/10").
    Currently I am making my first steps with a SL40 and I am testing several things, including the spindle. This lathe have a massive chuck (18") and a gearbox. When rotating the spindle at max speed (2400rpm) and asking for a lower speed (for example 1000) the braking noise is very high, I would say a mixture of mechanical (probably from the gear box ?) and electrical.
    I understand that the mass that is rotating is very high due to the chuck size, but at the same time the audible noise even frightens me, and I would like to get an opinion on a Haas user with a similar machine.
    Does yours make too much noise when stepping down speed?

    Would it be possible to increase the deceleration time so that it would be more gentle?

    Thank you.

    It is possible to increase the deceleration time. Do you have a video?
