Sinner, who is aiming to usurp Carlos Alcaraz as world number one, had not dropped a set in 18 ATP Masters 1000-level matches heading into Thursday's tie.
However, Machac took the second set to force a decider, with Sinner ultimately prevailing 6-1 6-7 (3-7) 6-3.
Fifteen unforced errors from Sinner caused a wobble in the second set, with Machac capitalising via a tie-break.
Yet Sinner regained his composure in the decider, teeing up a quarter-final against Felix Auger-Aliassime.
Sinner is a two-time semi-finalist in Monaco, but he has never won the event.
