Steady rest for supporting a workpiece being machined

A steady rest for supporting a workpiece that is to be mechanically machined, comprising:

• a steady rest main body configured to be arranged in a device for mechanical machining of the workpiece, and
• two supports, wherein each of the two supports is arranged or formed on the steady rest main body and is intended for supporting the workpiece, wherein each of the two supports comprises at least one workpiece supporter configured to support the workpiece,
• wherein each of the two supports is arranged or formed on the steady rest main body so as to be movable, relative to the steady rest main body, in at least one degree of freedom of movement along a movement path of each respective support,
• wherein the two supports are motion-coupled via an actuating device arranged between and coupling the two supports to each other, wherein a first end of the actuating device is coupled to a first support of the two supports via a first coupling portion or a first coupling apparatus and a second end of the actuating device is coupled to a second support of the two supports via a second coupling portion or a second coupling apparatus,
• wherein the steady rest main body comprises two ramp-like guide portions that are arranged so as to be at an angle relative to one another, each of the two supports being arranged or formed on a respective ramp-like guide portion of the steady rest main body so as to be movable, in the at least one degree of freedom of movement, relative to the respective ramp-like guide portion of the steady rest main body,
• wherein opposing ends of the ramp-like guide portions extend towards each other and respective end faces of each of the opposing ends of the two ramp-like guide portions are opposite to and facing one another and;
• and
• wherein the ramp-like guide portions transition, in a region of respective opposing ends thereof, into a ridge formed by the respective opposing ends thereof.
