ø 83 mm blind flat burrs in DLC-coated K110
83 mm flat burrs in K110 steel with DLC (Diamond-Like Carbon) coating to minimize the coefficient of friction.
Designed without exposed screws to provide a homogeneous grinding surface and reduce ground coffee retention.
The special three-phase geometry (breaking, slicing, and compressing) maximizes flavor expression from filter to espresso.
The long exit terminals cause additional fragmentation by compression, allowing for increased TDS in the cup.
Asymmetric geometry between the upper and lower burr optimizes coffee flow in
single-dose use.
Lifespan up to 10 tons.
The production process of Ceado burrs
01 Machining and shaping
It all begins with high-alloy steel bars of selected quality, cut into raw discs according to the required diameter (50, 64, 83 mm). On twin-spindle robotic lathes and Ceado’s customized machines, each disc is processed to create holes, parallel surfaces, and the unique toothed geometry that will define the aromatic profile in the cup.
02 Heat treatments
To achieve optimal hardness, the burrs are hardened at over 1000°C and cooled in oil or through cryogenic treatment at -70°C. The subsequent grinding process removes thermal deformations, ensuring perfect flatness and parallelism between the grinding surfaces.
03 Finishes and coatings
Ultrasonic cleaning, brushing, and precision lapping bring flatness down to the micron. Special coatings (Opalglide, Red Speed, DLC, Titanium Nitride) improve smoothness, reduce friction, and enhance durability or cup performance according to specific requirements.
04 High-precision alignment
Ceado ensures perfect perpendicularity of the rotation axis to the burrs by controlling three key factors: surface leveling, burr pair parallelism, and perpendicularity to the motor shaft. This guarantees consistent performance even after burr replacement.
Burrs are the heart of flavor. At Ceado, we design and manufacture each burr in-house, with focus on the desired aromatic coffee profile while ensuring perfect integration between grinder and burr. Ceado Burrs Machinery is a unique place, entirely dedicated to burrs: here, the selection of the purest steels meets ultra-precise mechanical processing and specialized coatings that define performance and durability.
