Acaia Orbit Grinder

Overview

Acaia's first-ever coffee grinder, the Orbit lands with unique features to meet your coffee brewing needs. The grinder is single-dosing friendly with features like an automatic cleaning purge that helps to reduce retention when grinding. If you prefer to pair with the latest Acaia Lunar, you can also activate Orbit’s grind-by-weight function and enjoy an effortless dosing experience. It is built and designed with Acaia’s proprietary tech-nology from the motor driver to the companion app, offering advanced control of RPM and overall energy savings.

64mm Flat Burr Platform & Burr Options

At the heart of the Acaia Orbit is a set of 64mm flat steel burrs, placing it firmly in prosumer and light commercial territory. Burr diameter at this size supports strong grind consistency and balanced particle distribution across espresso and filter ranges. The Orbit is not locked into a single flavor philosophy either. Acaia offers multiple burr options tailored to different brewing goals, from classic espresso profiles to high clarity light roast extractions.

For those chasing modern flavor expression, certain burr sets lean toward higher clarity and sweetness, especially appealing for lighter roasts and filter brewing. Others are tuned for traditional espresso body and texture. It is not just a grinder. It is a platform designed to evolve with your brewing style.

RPM Stability Control Technology

One of the Orbit’s most technically interesting features is Acaia’s RPM Stability Control Technology. In many grinders, motor speed fluctuates as bean load decreases. RPM can spike near the end of a dose, increasing heat and affecting particle consistency. The Orbit actively stabilizes motor speed throughout the grind cycle, maintaining consistent revolutions per minute regardless of hopper load.

The practical outcome is reduced noise, lower heat generation, and more uniform particle size. From a mechanical standpoint, consistent rotational speed means more predictable shear forces at the burr interface. From a cup perspective, that translates to repeatable extraction and balanced flavor.

Single Dose Workflow & Retention Management

The Orbit was purpose built for single dosing, and that intention shows in its design. It features a knocking chute and automatic purge system that work together to minimize retention between doses. Automatic cleaning helps clear residual grounds from the burr chamber, reducing cross contamination between coffees and tightening dose accuracy.

For users who rotate beans frequently or value precise workflow, minimizing retention is not just convenient. It is essential. The Orbit’s approach is engineered rather than improvised.

Grind by Weight Integration with Acaia Lunar

When paired with the Acaia Lunar scale, the Orbit enables true grind by weight functionality. The grinder communicates directly with the scale to automate start and stop functions, grinding precisely to your programmed dose without pre weighing beans.

This integration supports both single dose and batch workflows. Instead of relying on timed approximations, the system responds dynamically to real time weight data. It is a measurable upgrade in dosing precision, particularly for espresso where even small deviations can alter shot time and extraction balance.

Stepless Adjustment & App Based Customization

Grind control is handled via a stepless adjustment dial, allowing fine micro adjustments from espresso to filter. The Black and White models feature a wide dial for tactile control, while the Space Gray version adds a detent ring to help mark repeatable positions across brewing methods.

Beyond the physical interface, the Orbit connects to a companion app that unlocks customizable grinding presets and RPM profiling. Users can tailor three programmable presets and adjust motor speed directly from their smartphone. It blends mechanical precision with digital control in a minimalist design that remains highly technical under the surface.

Features

SINGLE-DOSE: Weigh your whole beans and grind with minimum retention. Pull a perfect shot without waste.

64 MM BURRS: Available with Mazzer 33M 64 mm burrs or SSP Multi-Purpose burrs, the Orbit is perfect for espresso and filter brewing.

ADJUSTABLE RPM: Use the Orbit App to customize your grinding experience: adjust the grind speed between 600-1500 RPM, swap the Orbit button actions, save profiles for grind-by-weight or grind-by-time, and more.

ORBIT TOLERANCES: All Orbit parts are individually measured and tested during the quality control process. This is to ensure they meet our precise standards and allow for the best burr alignment. For example, our grinders must meet or exceed the following: Burr mounting surfaces - 10 microns in flatness Motor drive shafts - 20 microns in concentricity Other critical parts - 20 micron tolerances

GRIND-BY-WEIGHT: Connect your Lunar scale to the Orbit. Grind precisely the right amount every time.

STEPLESS ADJUSTMENT: Orbit’s 0.75 mm thread pitch allows you to fine-tune your grind settings to dial in your shot accurately, from light roast to dark roast coffee.

ENERGY EFFICIENT: Developed with our in-house technology over the years, Orbit is designed to minimize energy consumption while delivering exceptional industrial performance and smart grinding.

BURR ALIGNMENT: Following assembly, we conduct thorough testing on each grinder to guarantee optimal functionality, alignment, and grind quality. We use optical imaging software to assess ground coffee for an expected level of uniformity, and measure the distance between the burr lock point and burr touch point. Acceptable distances are < 1.5 marks for Mazzer 33M burrs and < 1 mark for SSP Multi-purpose burrs
