Coffee Grinder Burr

The coffee grinder burr set is the core fixed component of a coffee grinder. The MIM (Metal Injection Molding) coffee grinder burr features an integrated design, incorporating progressive cutting teeth, an internal cooling structure, and precise mounting interfaces. Through metal injection molding technology, we have achieved complex internal cavity structures and optimized tooth profiles that are difficult to produce with traditional machining, ensuring a smooth transition from coarse crushing to fine grinding and minimizing the production of fine powder..

Product Feature And Application

The coffee grinder burr is the core component determining coffee grinding quality and must simultaneously meet stringent requirements for high hardness, extreme wear resistance, precise tooth profile, lightweight design, and hygiene safety. MIM technology provides a breakthrough solution for this:
Achieving Integrated Molding of Complex Blade Structures
Enables one-step precision molding of microscopic blade arrays for conical, flat, or specially shaped burrs, including complex geometric features.Traditional processes (such as wire cutting + grinding) require multi-step assembly, whereas MIM achieves near-net shaping of the entire component, eliminating assembly errors.
Enhancing Performance and Lifespan
Utilizes MIM 440C stainless steel material, achieving a hardness of HRC58-62 after sintering and heat treatment, with wear resistance 3-5 times higher than traditionally cast burrs.Through pore control technology, the burr achieves uniform density, preventing localized chipping and extending service life.
