Precision CNC Machining for Demanding Industries
We machine production components from your drawings — aluminium, stainless, titanium and engineering plastics — for semiconductor equipment, photonics, medical instruments and high-reliability industrial hardware. Every quote includes a written DFM review, and every new part number receives first-article inspection.
Shenzhen Xinyuanmu Precision Manufacturing is a contract manufacturer of precision machined and turned components based in Shenzhen, China. The company produces custom CNC milled and turned parts for semiconductor equipment, photonics and optical-communication systems, medical device instruments and high-reliability industrial equipment, serving customers in North America, Europe and Asia-Pacific with DFM review, first-article inspection and material traceability.
What we manufacture
Each product page states the tolerance and order range up front, so you can tell in ten seconds whether it fits your requirement.
CNC Machined Precision Parts
CNC machined parts are metal or plastic components produced by subtractive cutting on computer-controlled milling and turning centres. Xinyuanmu Precision machines custom parts from customer drawings across aluminium, stainless steel, titanium and engineering plastics, targeting ±0.05 mm on general dimensions and tighter bands on critical features, with a written DFM review before every quote and first-article inspection on new part numbers..
Specifications and process
CNC Turned Components
CNC turned components are rotationally symmetric parts produced on lathes where the workpiece spins and a stationary or driven tool removes material. Xinyuanmu Precision turns shafts, pins, bushings, fittings and threaded parts with live tooling for cross-drilling and milling in the same setup, targeting ±0.05 mm on diameters with tighter bands confirmed by inspection, from a single prototype to small-batch production..
Specifications and process
Semiconductor Equipment Components
Semiconductor equipment components are the structural, vacuum and optical-mounting parts inside wafer-handling, inspection and process tools. Xinyuanmu Precision machines these parts from aluminium, stainless and specialty alloys to tight tolerances, with first-article inspection, material traceability and clean handling appropriate to the tool environment..
Specifications and process
Photonics & Optical Components
Photonics and optical components are the mounts, housings and structural parts that hold lenses, fibres and optical sub-assemblies in alignment. Xinyuanmu Precision machines these parts from dimensionally stable materials to tight tolerances, with surface finish and clean handling controlled so that alignment and stray-light performance are preserved..
Specifications and processProcesses under one engineering gate
Milling, turning, tight-tolerance work, DFM/NPI support and inspection are handled under the same engineering review, so a part does not lose its dimensional record when it moves between operations.
CNC Milling (3/4/5-Axis)
CNC milling from 3-axis to simultaneous 5-axis for complex prismatic parts.

Sectors we supply — and the constraints each one imposes
Semiconductor Equipment
Semiconductor equipment manufacturing requires components with tight tolerances, stable materials and clean handling so that wafer-handling, inspection and process tools hold alignment and vacuum integrity. Xinyuanmu Precision machines structural, vacuum and optical-mount hardware from aluminium, stainless and specialty alloys, with first-article inspection, material traceability and packaging suited to the tool environment..
Requirements and partsPhotonics & Optical Communications
Photonics and optical-communication systems depend on mechanical parts that hold lenses, fibres and optical sub-assemblies in alignment. Xinyuanmu Precision machines mounts, housings and structural frames from dimensionally stable materials to tight tolerances, with surface finish and clean handling controlled so alignment and stray-light performance are preserved..
Requirements and partsMedical Devices
Medical device machining requires material traceability, documented process control and surfaces that resist corrosion and cleaning. Xinyuanmu Precision machines instrument bodies, housings and equipment components in stainless steel, titanium and engineering plastics, with first-article inspection, material certificates and heat-number traceability, limited to non-implantable, non-patient-contact parts under our current quality system..
Requirements and partsHigh-Reliability Industrial
High-reliability industrial equipment — automation, instrumentation, test and measurement — needs low-volume, high-mix parts where design iteration speed and repeatable fit matter more than unit cost. Xinyuanmu Precision machines brackets, fixtures, end effectors and instrument hardware in short lead times, holding mounting-interface tolerances so parts from different batches assemble without rework..
Requirements and partsWhat the production area actually looks like
Procurement teams get burned by suppliers whose website shows a gleaming showroom and whose shop floor is four tired machines. So the facility page describes the workflow honestly — what happens in each area, and what we do not do in-house — rather than publishing an equipment count we cannot verify.
Engineering reference, written for buyers
Definitions, tolerance tables and cost mechanics — the questions that come up before a purchase order, answered with numbers rather than adjectives.

What is your minimum order quantity?
One piece for machined and turned parts. There is no tooling charge on machined work, so a prototype and a small production run use the same process — only the per-unit price changes with volume.
Which industries do you supply?
We focus on semiconductor equipment, photonics and optical communications, medical device instruments and equipment, and high-reliability industrial and instrumentation hardware. Controlled defence, aerospace-flight and nuclear work is reviewed through our compliance gate before any data is exchanged.
Do you supply material and inspection certificates?
Material certificates are available with shipments, and heat-number traceability can be provided on request. First-article inspection reports accompany new part numbers. We state clearly which documents we can issue and which require a certified partner.
How do you handle shipping and duties?
We ship FOB Shenzhen by default, and EXW or DAP where you prefer. For US and EU customers we provide the commercial invoice and country-of-origin details needed for customs entry.
Can you work from a 3D model without a 2D drawing?
Yes, but tolerances must then be agreed in writing, because a model carries nominal geometry only. We propose a tolerance table for your approval before machining — assuming tolerances silently is how disputes start.
Do you claim ISO or aerospace certifications?
No. We do not claim management-system certifications we do not yet hold. We operate a documented inspection and traceability process and are transparent about which records we can provide today.
