Products Description
This 64mm titanium flat burr coffee burr has the characteristics of high strength and good corrosion resistance. Compared with some other materials' burrs, the titanium alloy burr is more durable, not easy to rust and wear, and can maintain the grinding performance for a longer time.
machining process
- Blank and foundation forming: titanium alloy round bar blank is selected, after annealing and softening, a flat disc matrix with a diameter of 64 mm is roughly turned by a high-rigidity numerical control lathe, and the finishing allowance is reserved, and at the same time, it is fixed by a special fixture to avoid clamping deformation.
- Precision cutting of tooth pattern: Five-axis CNC machining center, equipped with TiAlN coated cemented carbide cutter, milling radial or arc tooth pattern at low cutting speed and high feed rate, and controlling tooth pitch accuracy by rough milling and fine milling to meet the demand of coffee grinding.
- Post-treatment strengthening performance: cooling with 70-100 bar high-pressure emulsified coolant to avoid high processing temperature. After that, the surface is nitrided, and PVD coating can be made to improve the wear resistance, and then the burr is removed by numerical control polishing.
- Precision detection and calibration: use a three-coordinate measuring instrument to detect parameters such as diameter and flatness, and a tooth profile measuring instrument to verify the tooth profile accuracy, so as to ensure that the meshing gap between the dynamic and static grinding cores reaches the standard and ensure the grinding uniformity.
The influence of titanium alloy on grinding effect
Titanium alloy has the advantages of high strength (close to steel), low density (lightweight), rust resistance, and excellent wear resistance. Some stainless steel burrs will be "titanium-plated". CNC machining of titanium alloy burrs can make the tooth pattern more refined (such as thinner burrs ), force is evenly distributed during cutting, and the particle uniformity is close to that of ceramics, but it is more impact-resistant than ceramics (not easy to crack). Titanium alloy has better heat dissipation than ceramics and stainless steel, generates less heat during grinding, and can retain the aroma of coffee beans to the greatest extent (especially suitable for the floral and fruity aroma of lightly roasted beans). However, the cost is high (the price is 3-5 times that of stainless steel), and it is only used in high-end grinders. It is suitable for commercial high-end grinders and home scenes with extremely high requirements for flavor and durability (such as professional coffee studios).
About us
We support processing of a variety of materials, mainly including metals (stainless steel, aluminum alloy, carbon steel, brass, copper, titanium alloy, etc.) and plastics (POM, ABS, PET, PP, etc.).
Our experts will provide advice on the most suitable material selection based on your project needs.
CNC milling (with carbide milling cutter) to process the outer circle, center hole, and back positioning step. Using custom-made forming tools (tooth shape matches the cutter head tooth pattern) on CNC machine tools for slotting or hobbing can ensure that the pitch error is ≤0.01mm.
We support a variety of surface treatment processes, including anodizing, electroplating, polishing, knurling, etc.
Titanium alloys can be anodized (forming an oxide film to enhance surface hardness and rust resistance).
Our services include demand communication, drawing/sample confirmation, process optimization quotation, contract signing, production quality inspection, logistics delivery, etc. Customers first communicate their needs with us and provide relevant drawings or samples. Then we optimize the process and quote. After both parties reach an agreement, we sign the contract and enter the production stage. Quality inspection is carried out during the production process, and finally logistics delivery is completed.

Material selection
Materials that can be used to make coffee machine burrs:
1.Standard burr: Usually oil-hardened steel burr, the most common type of burr, mostly gray in appearance. This burr has a hardened layer and a soft "inner core". When the hardened layer wears out, the burr will wear faster. A 64mm standard steel burr can grind about 650-750 pounds of coffee beans before it needs to be replaced.
2."Enhanced" burr: The hardened layer is strengthened through a high-frequency quenching process, which increases the service life of the standard burr and can be identified by the increased gloss and more silver on the burr. The 64mm "enhanced" burr can grind about 1000-1100 pounds of coffee beans before it needs to be replaced.
3.Chrome-molybdenum steel burr: Made of chrome-molybdenum alloy steel, it is slightly more expensive and has the characteristics of high strength, high hardness, wear resistance, and high temperature resistance. A 64mm chrome-molybdenum steel burr can grind about 1500-1600 pounds of coffee beans before it needs to be replaced.
4.D2 tool steel burr: This is an expensive type of burr that is hard and wear-resistant, but it needs to be heated to very high temperatures during processing, and manufacturers need special equipment to produce this type of burr. A 64 mm D2 tool steel burr can grind 2400-2500 pounds of coffee beans before it needs to be replaced.
5.TiN-coated D2 tool steel burr: Titanium nitride coating is applied to the surface of the D2 tool steel burr. Titanium nitride has a low coefficient of friction, super hardness and wear resistance, and provides additional protection for the D2 tool steel burr. It has a golden appearance. A 64 mm TiN-coated D2 tool steel burr can grind 3000-3100 pounds of coffee beans before it needs to be replaced.
6.Ceramic burr: The service life is similar to that of the TiN-coated D2 tool steel burr, and it can grind 3000-3100 pounds of coffee beans. The advantage of ceramic burrs is that they can dissipate heat fairly quickly and are more resistant to high temperatures than metals. However, ceramic burrs have poor toughness and are prone to cracking or breaking after long-term use.
This "64mm titanium flat burr coffee burr" is made of titanium alloy material and CNC processing technology. Some high-end home grinders use titanium alloy blades, such as the Ep60 coffee grinder, which is equipped with a 60mm diameter titanium alloy blade. It is sturdy and durable, can enhance the aroma of coffee brewing, and is suitable for home users to make various types of coffee such as Italian, mocha, and hand brew. In commercial coffee making scenarios, such as cafes and restaurants, due to the need to frequently grind a large number of coffee beans, the durability and grinding effect of the blade are required to be high, and titanium alloy blades are also widely used. For example, the Black Hawk MYTHOS1 grinder uses a 75mm diameter nano-coated titanium alloy blade, which can grind up to 1200KG of coffee, ensuring efficient and long-lasting grinding.
