That looks more like a viscometer since that arm is way to puny to handle much in the way of stress or torque from a cutting head biting into something gummy like titanium(http://img.directindustry.com/images_di/photo-mg/69528-9964713.jpg)The drawing is definitely a much older model than what is in this image though - my google-fu is weak
This is what I worked with years back and they have not changed all that much since except having actuators replacing the hand cranks and a PLC attached to the side.

In the original picture that can is a big give away as is the horizontal support being so slim with such a huge control box mounted on it.
What you think is a cutting head is much too big for a tool holder on such a small piece of equipment but is the right size for a strain gauge based torsion sensor

My guess is that drawing a retort stand was more of a challenge than just going with the go-to industrial extrusions for the support fixture and the large control box reflects that the design is a few decades old
I have worked with one like the pic on the right that had a bigger head and sample were in paper coffee cups - super cheap and disposable - which is good since the polymer cures to a very hard and durable insulating material that does not combust easily - which was a very good thing since they were making industrial insulators (https://sc02.alicdn.com/kf/HTB1EtbjKVXXXXX_aXXXq6xXFXXXT/High-voltage-Power-line-insulators.jpg)
and now back to our regularly scheduled sillyness
Sam: Help? My drawstring got pulled into this thing.
Faye: I'm not sure how you even managed to do that.
Bubbles: I think we found our Raven or our Raven found us.
Not knowing anything about it myself, what exactly would you do with a rotational viscometer in a robot repair shop?
Custom blended hydraulic fluid for the discerning android-about-town?
Or, indeed, measuring the fluid they just drained off to make sure it’s within spec.
My experience has been with the QC testing of polymers. Either thermo-set or epoxy. You need a specific level of viscosity for molding or potting parts but not too thin else it will leak like water and be weak or too thick and leave voids.
Testing thinner fluids like lubricants or blood is usually relegated to a custom glass tube type system, a stopwatch and a look-up table. (http://pim-resources.coleparmer.com/item/l/cannon-9721-r59-viscometer-size-1-2-to-10-centistokes-9893413.jpg)
