Grind setting conversion
Rancilio Rocky vs Timemore Sculptor 064
Two grinders cross-shopped at the same money. The Sculptor 064 is numbered 0–16; the Rocky is numbered 0–55.
| Rocky | Sculptor 064 | |
|---|---|---|
| Brand | Rancilio | Timemore |
| Scale | Numbered dial | Numbered dial |
| Dial range | 0 – 55 | 0 – 16 |
| Burrs | Flat | Flat |
| Espresso → filter | 20 numbers | 3.5 numbers |
| Filter → coarse | 23 numbers | 12.5 numbers |
The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 8 sits at grind index 5.6 on the Rocky but 58 on the Sculptor 064 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the Rocky
A stepped espresso grinder that has been the budget recommendation for a very long time. The 55 steps across 50mm flat burrs are its limitation — for espresso you will sometimes want a setting between two of them and there is not one, and a single step can move a shot by seconds. Twenty of those steps cover espresso through filter, which is more resolution than the fine end usually gets at this price. Two things make it an espresso grinder in practice rather than a general one: changing setting means holding the locking lever while twisting the hopper, and it keeps a couple of grams in the chute, so every switch between espresso and pour over costs you both fiddling and coffee. Most owners pick one end and stay there.
Dialing in the Sculptor 064
Timemore's move upmarket into electric flat-burr grinding, with a genuinely usable espresso range unlike their hand grinders. Single dose oriented, and noticeably more consistent through filter than the C-series it sits above.
