When a tiny machined component has to survive inside a medical device, an aerospace assembly, or a piece of automation equipment, precision is not a luxury—it is a requirement. A deviation of just a few microns can mean the difference between a part that fits perfectly and one that fails in the field. That is why design engineers and procurement teams increasingly turn to a dedicated
precision cnc machining partner rather than a general-purpose shop.
ANOK Precision Manufacturing, a custom precision machining factory founded in 2007 in ShenZhen, China, has built its reputation around holding tolerances down to ±0.002 mm and surface finishes down to Ra 0.2. From a single prototype to medium and large production batches, the company delivers turnkey parts in metals and plastics for industries spanning medical, aerospace, food, agriculture, and automation.
What high precision CNC machining really means
True precision machining is measured in micrometers. Achieving ±0.002 mm tolerance requires more than capable machines—it demands rigid process control, skilled programming, careful tooling, and repeatable measurement. ANOK combines a full spectrum CNC machine shop with first-class equipment and seasoned technicians to hold these tolerances across complex geometries, including
5 axis cnc machining services that synchronize X/Y/Z linear axes with A/B rotary axes for multi-angle cuts without part repositioning.
Capability at a glance
Tolerances down to ±0.002 mm (up to ±0.005 mm for complex geometries), surface roughness down to Ra 0.2–0.4 µm, 50+ machining facilities in machining centers, and 4-axis and 5-axis machining capabilities in-house.
A full complement of processes under one roof
Precision is rarely the work of a single operation. ANOK provides six core services so that a part can move from raw stock to finished component without changing suppliers: CNC milling,
cnc turning, precision
surface grinding,
wire edm, coating and surface treatment, and high precision assembly.
- CNC machining: 3-axis, 4-axis, and 5-axis milling of metals and plastics, with tight tolerances down to ±0.002 mm.
- CNC turning: nearly 15 machines running up to 20 hours a day, handling bars and blocks into cylindrical parts with threads; max part diameter 520 mm and max length 3600 mm.
- Surface grinding: flatness, parallelism and finish down to Ra 0.4 (mirror Ra 0.2 achievable via polishing), with tolerance within ±0.002 mm.
- Wire EDM: precision cutting of hardened steel, titanium, carbides, and graphite with tolerance as tight as 0.003 mm and smallest hole diameter 0.07 mm.
- Coating and surface treatment: anodizing, electroplating, powder coating, passivation, blackening, and chemical treatments, with aluminum surface variance under 5 µm.
- High precision assembly: machining fixtures, assembly fixtures, checking fixtures, and module assembly to micrometer accuracy, plus sheet metal, 3D printing, and injection molding.
Pushing the limits on difficult materials
Many shops struggle with tough-to-machine materials. ANOK is experienced with titanium alloy (Ti-6Al-4V), Inconel nickel-based alloy, and PEEK, alongside a broad catalog from aluminum and stainless steel to brass, copper, magnesium, tool steel, and engineering plastics like nylon, POM, PTFE, and ULTEM. This material depth matters when a design calls for high strength, low weight, or high-temperature resistance—and it is one reason the factory is trusted for
cnc machining services china buyers rely on for demanding applications.
Built for demanding industries
Precision only means something in context. ANOK serves eight industries with custom machined parts: medical and dental components from titanium and 316/304 stainless steel, food equipment and packaging parts,
cnc machining services for motorcycle and automotive components, precision agriculture components, mechanical parts for energy and oil & gas, telecommunication parts for 5G and satellite communication, aerospace parts meeting MIL-STD-810G and FAA/EASA airworthiness requirements, and automation and robotics components.
A few examples illustrate the level of work: endoscope tubes with an inner diameter of just 0.2 mm and roughness up to 0.05 µm, MPO guide pins for fiber connectors with roundness tolerance ±0.0001 mm, and dental articulator components assembled to 0.015 mm. These are the kind of parts where a general machining vendor cannot deliver.
Quality, certification, and accountability
Meeting tight tolerances once is not enough; they must be held consistently. ANOK is certified to ISO 9001:2015 and references ISO 13485 and AS9100 standards for medical and aerospace work. The company traces its history from a 2007 mold workshop through an overseas-owned factory in 2009, a dedicated precision machining department in 2011, ISO 9001:2015 certification in 2018, and a move to a new factory in 2021. It has exhibited at HANNOVER MESSE and visited customers across Denmark, Germany, Switzerland, Norway, and the Netherlands—evidence of a partner comfortable working with demanding international buyers.
