How to Clean the Timemore Sculptor 064S Chute and Knocker
The Timemore Sculptor 064S keeps its chute clear with a rotary knocker and needs only dry tools day to day. This guide is researched from Timemore product pages, retailer documentation and a published long-term review.

Quick answer: Timemore Sculptor 064S cleaning
Turn the Sculptor 064S rotary knocker a few clicks after every dose with the cup still in place, brush the chute outlet daily, and blow out the chute with an air blower. Open the six-screw Sculptor 064S burr chamber only when the chute clogs or grind output changes, then recheck the dial's zero point.
What the Timemore Sculptor 064S rotary knocker does
The Timemore Sculptor 064S rotary knocker is a ring around the chute that you turn by hand to jolt loose grounds out of the spout. Timemore says the Sculptor 064S rotary knocker reduces leftover fines, and Timemore Australia calls it a knock collar for clearing old fines. The Coffee Chronicler review describes the Sculptor 064S knocker as clicky and easy to grip, and reports retention getting closer to zero when the knocker is used.
The Sculptor 064S knocker replaces the bellows or hand-tapping that other single-dose grinders rely on. Because the knocker works on the chute rather than the burrs, it keeps day-to-day cleaning to a few seconds and delays the need to open the grinder.
After-every-dose routine for the Timemore Sculptor 064S chute
- Close the Sculptor 064S magnetic lid before grinding; retailer guidance notes the closed lid reduces popcorning, which keeps beans in the burrs and chaff out of the chute.
- Let the grind finish. The Sculptor 064S shuts off automatically after 60 seconds.
- Leave the grind cup in place and turn the rotary knocker a few clicks, so dislodged fines land in your dose rather than on the counter.
- Remove the cup and sweep the chute outlet with a soft brush.
- At the end of the day, blow out the chute with an air blower. Retailer guidance for the Sculptor 064S is to clean with a brush or air blower and avoid disassembling internal parts unless necessary.
Weigh the Sculptor 064S output against the input dose once in a while. If the output drops noticeably below the input, fines are building up in the Sculptor 064S chute and need clearing before they go stale. For why a gram or two matters, see grinder retention explained.
Clearing a clogged Timemore Sculptor 064S chute
A clogged Timemore Sculptor 064S chute usually shows up as a slow or spitting grind, clumps in the cup, or output weighing well under the dose. Work through the Sculptor 064S chute clog from least to most invasive:
- Unplug the Sculptor 064S.
- Turn the rotary knocker repeatedly over an empty cup.
- Push a soft brush into the chute opening and sweep outward.
- Use an air blower from the outlet side to lift compacted fines.
- If the Sculptor 064S chute stays blocked, the packed coffee sits at the burr exit, and the burr chamber has to be opened (next section).
Oily dark roasts and very fine espresso settings pack chutes faster, and static makes fines cling; for static fixes, see how to reduce grinder static. A similar chute problem on another 64mm grinder is covered in DF64 chute clogged: cleaning and prevention.
Deep cleaning the Timemore Sculptor 064S burr chamber
The Timemore Sculptor 064S burr chamber rarely needs opening. The Coffee Chronicler review found only tiny amounts of build-up in the Sculptor 064S chamber after extended use, but it also notes that burr access requires removing six screws rather than a tool-free release. Timemore does not publish a Sculptor 064S teardown on its product pages, so treat burr removal as an occasional job, not a routine.
Before opening the Timemore Sculptor 064S
- Unplug the Sculptor 064S power cord; the Sculptor 064S cord is detachable, so remove it from the grinder entirely.
- Photograph each stage so the Sculptor 064S parts go back in the same orientation.
- Keep the Sculptor 064S dry. Use the brush and air blower only, and handle burr edges carefully because they are sharp.
- Note the current dial number, because the Sculptor 064S zero point needs checking after reassembly. The Sculptor 064S magnetic dial indicator pops off so you can realign it to zero without tools. For the concept, see burr alignment and calibration.
Reference: Sigma Coffee's Sculptor 078 teardown
Sigma Coffee UK publishes a step-by-step teardown for the Sculptor 078, the larger-burr sibling of the Sculptor 064S. Sigma states that its guide applies only to the Sculptor 078, so use it as a picture of the general layout rather than as Sculptor 064S instructions. The Sculptor 078 sequence removes the friction-fit adjustment dial, a locating plate, six 3mm hex screws on the burr support plate, and then the burr plate; Sigma also warns to disconnect power first and to avoid wiping lubricant off the motor spindle. If a Sculptor 064S step does not match, stop and contact Timemore support rather than forcing a part.

Timemore Sculptor 064S cleaning FAQ
How often should I clean the Timemore Sculptor 064S?
Use the Sculptor 064S rotary knocker after every dose and brush the chute outlet daily. Open the Sculptor 064S burr chamber only when grind output changes, the chute clogs, or you switch to a very different roast; a published review found little build-up inside the chamber, and retailers advise avoiding disassembly unless necessary.
How do I use the knocker on the Sculptor 064S?
After the grind stops, turn the Sculptor 064S rotary knocker a few clicks while the grind cup is still in place, so dislodged fines fall into the cup rather than onto the counter. Timemore says the rotary knocker reduces leftover fines in the chute.
How many screws hold the Sculptor 064S burrs?
The Coffee Chronicler review reports that reaching the Sculptor 064S burrs means removing six screws, and it notes that many competing grinders offer tool-free burr access instead.
Can I wash Sculptor 064S parts with water?
Clean the Sculptor 064S with a brush and an air blower. Retailer guidance for the Sculptor 064S names only dry tools, and Timemore does not publish washing instructions, so keep water away from the grinder body, chute and burrs.
Do I need to recalibrate the Sculptor 064S after cleaning the burrs?
Check zero after reassembling the Sculptor 064S burrs. The Sculptor 064S magnetic dial indicator pops off, so you can realign it to the true zero point without tools.
