CNC machining micro parts manufacturer

Core Micro Machining Technologies

With 26 years of specialized experience in miniature component manufacturing, we have mastered the most advanced micro machining technologies to overcome the unique challenges of miniaturization:

• Swiss-type CNC Machining: We use top-tier Tornos Nano, Tsugami and Star CNC Swiss lathes, with guide bushing support that eliminates tool deflection, perfect for machining 0.010″-0.5″ diameter micro shafts, pins and connectors. Our machines achieve spindle runout as low as 0.5μm, ensuring ultra-stable precision.
• 5-Axis Micro Milling: Our 5-axis micro milling centers enable one-setup machining of complex 3D micro features, with spindle speed up to 60,000 RPM to eliminate burrs on miniature parts, achieving 99.9% burr-free rate for medical components (test data for reference only).
• Centerless Grinding: For ultra-precision micro shafts, we apply precision centerless grinding to achieve cylindricity control down to 0.0001″, meeting the strictest requirements for medical implant and aerospace actuator parts.

Overcoming Micro Machining Challenges

With 26 years of experience, we have developed specialized solutions to solve the common pain points of micro parts manufacturing that trouble most general CNC shops:

• Tool Deflection Control: We use ultra-rigid micro carbide tools with TiAlN coating, and optimized cutting parameters to eliminate tool deflection, even for 0.1mm diameter tools.
• Thermal Deformation Elimination: Our 20℃ constant temperature workshop, combined with in-process thermal compensation system, controls thermal expansion to within 0.2μm, ensuring stable precision during long production runs.
• Part Holding Solution: We use custom vacuum fixtures and adhesive clamping for tiny parts, eliminating clamping deformation that is common with traditional jaw chucks, ensuring 100% part integrity.
• DFM Optimization: Our engineering team provides free DFM (Design for Manufacturability) report for every project, helping you optimize design to reduce cost by 30% and shorten lead time by 50% (client case data for reference only).

Medical & Healthcare

The medical industry is the largest demand driver for micro CNC parts, with a 7.15% annual growth rate, as minimally invasive surgery and implantable devices require smaller and smaller components. We are ISO 13485 certified, and specialize in manufacturing:

• Orthopedic & dental micro titanium screws (as small as 0.2mm diameter)
• Surgical instrument components and minimally invasive tool parts
• Medical sensor electrodes and diagnostic device components
• Implantable device housings and spacers

Case Highlight: We helped a Fortune 500 medical client manufacture 0.2mm×0.1mm micro sensor electrodes, with ±0.005mm tolerance. Our solution improved the client’s product signal collection accuracy by 20%, and increased yield rate from 65% to 99.5% (project data for reference only).

Aerospace & Defense

With the reshoring trend in US aerospace industry, more and more manufacturers are looking for reliable micro parts suppliers that can meet AS9100 standard. We provide fully traceable micro components for:

• Lightweight sensor brackets and actuator parts
• Turbine engine micro cooling holes and fuel system components
• Defense electronics connectors and micro pins
• UAV and drone miniature transmission parts

Case Highlight: For an aerospace client, we manufactured titanium alloy micro connector parts with 1.5mm diameter bore, ±0.005mm tolerance. We solved the deformation issue of thin-wall parts, improved yield rate from 75% to 99.2%, and reduced the client’s supply chain cost by 42% (project data for reference only).

Electronics & Semiconductor

The semiconductor and electronics industry is driving miniaturization to new levels, requiring tiny components for 5G devices, semiconductor equipment, and robotics. We manufacture:

• Micro connectors and contact pins for high-speed electronics
• Semiconductor equipment thermal management parts
• Robotics end effector miniature components
• Optical device micro mounts and alignment parts

Case Highlight: For a semiconductor equipment client, we manufactured micro aluminum heat sink parts with 0.2mm wall thickness, ensuring no deformation during machining. The parts helped the client’s equipment achieve 15% better thermal performance, supporting their 3nm chip processing line.

For micro parts, quality control is far more critical than standard parts, as even a micron-level error can lead to complete product failure. We have built a full traceable quality system to ensure 100% compliance:

1. 1. Quotation & DFM Review: Our engineering team reviews your design, provides free DFM feedback and manufacturability analysis within 24 hours.
   2. Programming & Tool Setup: We use Mastercam for micro part programming, with custom tool path optimization to avoid tool breakage and deformation.
   3. Micro Machining
      
   4. 100% Inspection: All parts are inspected by Zeiss optical CMM and vision measurement system, complying with ISO 10360 standard, with full dimensional report provided.

1. 1. Cleaning & Packaging: Medical-grade cleaning and sterile packaging for medical parts, with anti-static packaging for electronics parts to avoid part damage.

We implement SPC (Statistical Process Control) for all mass production, ensuring Cpk > 1.33 for all critical characteristics, which guarantees long-term consistency of your parts (test data for reference only). We can also provide PPAP, FAIR, AS9102 and other documentation as required by your industry.

What tolerances can you hold for micro CNC parts?

We can consistently hold tolerances as tight as ±0.0001″ (2.5μm) for critical features of micro parts, and standard tolerance for micro parts is ±0.0005″. This is far tighter than standard CNC machining, to meet the requirements of medical and aerospace applications.

What is the smallest part you can machine?

Our minimum machining diameter is 0.1mm (0.004″), and we can machine features as small as 0.05mm. We can handle parts with wall thickness down to 0.2mm, which is perfect for the smallest medical implants and electronics components.

What certifications do you have for medical micro parts?

We are ISO 13485 certified for medical device manufacturing, and all our medical grade materials are compliant with ASTM and ISO biocompatibility standards. We can provide full material traceability, cleanroom packaging, and validation documentation as required.

What is the lead time for micro parts?

For prototype parts, we can deliver in 3-5 days. For small batch production, lead time is 10-14 days, and for mass production, it is 14-21 days. This is much faster than general micro machining shops, as we have dedicated production lines for micro parts.

Do you offer DFM support for micro part designs?

Yes! We provide free DFM (Design for Manufacturability) analysis for every micro parts project. Our engineering team will review your design, point out potential manufacturing issues, and provide suggestions to optimize your design for lower cost, higher yield and shorter lead time.

Can you ship to US and Europe?

Absolutely. We have extensive experience shipping to North America and Europe, with full customs documentation. We can handle DDP shipping, and we are compliant with US reshoring requirements, ensuring your supply chain is stable and compliant.
