What Is Micro Machining, and What Can MW+ Hold?

Micro machining is precision manufacturing of parts and features measured in microns — typically below 1mm — using CNC micro machining methods such as micro milling, micro turning, and micro EDM. It is specified whenever standard CNC machining cannot hold the required tolerance or resolve a feature that small.

MW+ is a precision micro machining company and micro machining Chinese company based in Shenzhen, China, operating a 5,000 m² ISO 9001:2015 facility with 70+ process engineers. As a micro machining manufacturer, we hold ±1µm (±0.001mm) across 150+ qualified materials, with full CMM documentation on every order — from a single prototype through 100,000+ unit production runs.

Our precision micro machining services span CNC micro milling, micro turning and Swiss micro machining, backed by 100% dimensional inspection and complete material traceability — so procurement teams can qualify MW+ as a micro machining supplier on data, not claims.

Decision Guide

Micro Machining vs. Standard CNC Machining

Engineers often ask when a part needs precision micro machining rather than standard CNC machining. The table below sets out where each process is the right specification.

ParameterPrecision Micro MachiningStandard CNC Machining
Typical tolerance±0.001–0.005 mm±0.05–0.1 mm
Typical feature sizeBelow 1 mmAbove 1 mm
Tooling & setupSub-millimeter tooling, thermal controlStandard tooling, ambient shop conditions

Common processesCNC micro milling, micro turning, Swiss micro machining, micro EDM3/4/5-axis milling, turning
Typical industriesMedical, aerospace, electronics, opticsGeneral industrial, automotive, structural

In practice, many components require both: a body machined on standard CNC equipment, and micro-featured details — bores, pins, threads, or micro-geometry — produced through precision micro machining in a second operation. MW+ runs both under one quality system, so tolerance handoffs between operations don't get lost.

FAQ

Micro Machining Questions, Answered

Common questions from engineers and procurement teams evaluating a micro machining supplier or micro machining manufacturer.

What is micro machining?+
Micro machining is precision manufacturing of parts and features measured in microns, typically below 1mm, using CNC micro milling, micro turning, or micro EDM. It's used where standard CNC machining can't hold the required tolerance or produce features that small.
What tolerances can precision micro machining achieve?+
MW+ routinely holds tolerances to ±1µm (±0.001mm) on precision micro machining orders, with measurement uncertainty as low as ±0.00005 inch, verified on CMM equipment with 0.5µm resolution.
Is MW+ a micro machining Chinese company?+
Yes. MW+ is a micro machining Chinese company headquartered in Shenzhen, Guangdong, operating a 5,000 m² ISO 9001:2015 certified facility and supplying micro-machined components to 30+ countries.
What's the difference between micro milling and micro turning?+
Micro milling uses a rotating cutting tool to create small pockets, slots, and complex 3D micro-geometry. Micro turning rotates the workpiece against a stationary tool to produce small-diameter cylindrical, stepped, or threaded parts.
What is Swiss micro machining used for?+
Swiss micro machining supports the workpiece close to the cutting tool, reducing deflection on long, slender parts. It's the standard method for micro shafts, connector pins, and medical screws with length-to-diameter ratios up to 20:1.
What materials can be used for precision micro manufacturing?+
MW+ micro machines 150+ qualified materials, including titanium Ti-6Al-4V, 316L stainless steel, nickel superalloys, copper and brass alloys, tool steels, and engineering polymers such as PEEK, PTFE, and POM.
How do I choose a reliable micro machining supplier in China?+
Look for ISO 9001 certification, published tolerance and Cpk data, 100% CMM inspection, material traceability, and a track record in regulated industries such as medical and aerospace. MW+ meets all of these as a micro machining manufacturer supplying worldwide.
What's the minimum order quantity and lead time?+
MW+ accepts orders from a single prototype piece up to full production runs of 100,000+ units, with typical lead times of 7 to 15 business days depending on part complexity and quantity.
How is micro machining different from standard CNC machining?+
Standard CNC machining typically holds ±0.05mm to ±0.1mm on parts above a few millimeters. Precision micro machining uses smaller tooling, thermal-controlled environments, and finer feedback control to hold ±1µm on features often below 1mm.
What does a micro machining manufacturer actually do?+
A micro machining manufacturer runs the tooling, CNC micro milling and micro turning programs, material certification, and 100% CMM inspection needed to produce micron-tolerance parts at production volume, not only single prototypes.
Can a micro machining supplier in China serve medical and aerospace OEMs?+
Yes, provided the supplier holds ISO 9001 certification, offers full material traceability, and can document Cpk and CMM inspection data. MW+ supplies precision micro machining services to medical, aerospace, and electronics OEMs in 30+ countries.
