Consumer Goods Industry, Coffee Grinder Components, Machining Capabilities

With our expertise, CNC multi-axis machining centers, 5-axis simultaneous milling machines, and precision Swiss turning machines are able to deliver high quality and precision made coffee grinder components. Knowing the consumer goods industry, the company transfers to every part the attention to detail that creates coffee grinder components. Every part, such as conical hardened steel burrs, grinding steel burrs, micro-stepped grind adjustment rings, static dissipative bean hopper bodies, polished flat burrs, and anti-vibration motor shafts, is designed and highly reliable for food practices and for processing over 500 kg of coffee beans.

We do precise CNC milling for burr tooth patterns keeping dimensional accuracy of ±0.008 mm and cutting angle tolerance of ±0.3 degrees and for complex conical burr geometries involving 5-axis machining with profile tolerance of ±0.010 mm. We also do precise turning for burr mounting surfaces with diameter tolerances of ±0.010 mm and Eccentricity of 0.008 mm, and precision flat face burr grinding with flatness achievable to ±0.005 mm and surface finishing of Ra 0.4μm, thread adjustment mechanism milling with pitch accuracy of ±0.012 mm and backlash control of 0.05mm, as well as precision boring of bearing seats with tolerances of ±0.008 mm. Finally, we do bulk material particle size distribution and wear testing for 100 kg grinding capacity.

We manufacture food-grade compliant burr sets from hardened stainless steel 420 with a hardness rating of HRC 58-62 and grinding chambers from stainless steel 304 with FDA CFR 21 certification and corrosion resistance. Our premium burrs are made from hardened tool steel (D2) giving them extreme wear resistance and edge retention. We also manufacture 6061-T6 Aluminum motor housings with anodized protection and heat dissipation. Other materials we use are food-grade ABS plastic for bean hoppers with static dissipative additives and food-grade polycarbonate (PC) for transparent UV resistant hopper windows. We also use brass for adjustment mechanism threads with consistent friction characteristics and ceramic coatings on burrs to extend wear life without altering the flavor of the coffee. We pride ourselves in food safety compliance to FDA CFR 21 and EU Regulation 10/2011, grind consistency down to a particle size deviation of 10%, and the ability to operate mechanically for more than 500 kg of coffee processing in a 5-year continuous daily use.

FAQs: Precision Coffee Grinder Components for Consumer Goods Industry Applications

Components of precision coffee grinders are hardened stainless steel conical burrs (outer diameters 38-71mm) with tooth geometry tolerances of ±0.008mm and hardness HRC 58-62, flat burr assemblies (diameters 58-83mm) with flatness of ±0.005mm and surface finishes Ra 0.4μm, grind adjustment rings with micro-step (18-40 settings) and thread pitches of ±0.012mm, bean hoppers (200-500g, wall thickness 2-4mm), motor coupling shafts with diameters tolerances of ±0.010mm and concentricity of 0.008mm, and grinding chamber housings with mounting hole errors of ±0.020mm. All components will be FDA CFR 21 compliant for food contact.

Hardened stainless steel 420 provides food safety and permits HRC 58-62 hardness for longer burr life. Its excellent corrosion resistance prevents rusting in humid conditions, zero flavor transfer keeps coffee taste pure, and wear resistance aids in processing 500+ kg beans. Also, stainless steel 304 provides FDA CFR 21 compliance in coffee grinding chambers, and other superior corrosion resistance from coffee oils and rancid cleaning solution, ease of cleaning and aesthetically good appearance in consumer appliances. Furthermore, Tool steel D2 has excellent wear resistance (HRC 60-62 hardness) superior edge retention to sustain consistent grinding for 1,000+ kg capacity and to grind into precise tooth geometry ±0.008mm of such gradeability.

The CNC milling machines create the burr pattern with a tolerance of ±0.008mm within the burr cutter profile and a cutting angle tolerance of ±0.3 degrees. The 5-axis machines are able to create cone burr profiles with a tolerance of ±0.010mm in the profile. The lathes use precision turning to create the mounting surfaces with a tolerance of ±0.010mm in the diameter and 0.008mm concentricity. The grinding machines are able to achieve burr faces with a tolerance of ±0.005mm in flatness and a Ra surface finish of 0.4μm. The adjustment mechanism was created with a thread milling with a pitch tolerance of ±0.012mm and a backlash of <0.05mm. The surfaces of the parts go through several treatments like vacuum heat treatment (HRC 58-62), electropolishing (Ra 0.3-0.5μm), passivation per ASTM A967 and in the case of stacks or woven burrs we also finish with a ceramic coating to improve the application.

We maintain burr tooth geometry tolerance ±0.008mm ensuring consistent particle size distribution ±10% standard deviation, cutting angle accuracy ±0.3 degrees for optimal grinding efficiency, flat burr flatness ±0.005mm preventing uneven wear and channeling, mounting surface concentricity 0.008mm ensuring wobble-free rotation at 400-1,400 RPM, adjustment thread pitch accuracy ±0.012mm with backlash <0.05mm for precise grind setting control, bearing seat tolerance ±0.008mm, surface finish Ra 0.4-0.8μm optimizing particle flow, and burr hardness HRC 58-62 providing wear resistance for 500+ kg grinding capacity.

Yes, we provide rapid prototyping with CMM inspection (±0.005mm accuracy), burr tooth geometry verification using optical microscopy, flatness measurement with precision dial indicators (0.001mm resolution), particle size distribution analysis using laser diffraction (measuring 100-1,000 microns), hardness testing per Rockwell HRC scale, concentricity measurement using precision runout gauges, grind consistency testing with 10+ kg coffee samples, and food safety certification per FDA CFR 21. We support low-volume production (1,000-15,000 annually) for specialty grinders and high-volume manufacturing (tens of thousands to millions) with dimensional certification, material compliance per FDA and EU 10/2011, particle distribution reports, wear testing data, and ISO 9001 quality documentation.
