Micro Machining Advantages
Sub-Millimetre Precision
Features as small as 0.05 mm with ±0.001" tolerances enable intricate designs. Miniaturisation of assemblies, reduced material use and enhanced performance — ideal for medical implants, optics and tight-dimension electronics.
Burr-Free Edges & Medical-Grade Finish
Inherently burr-free edges without secondary hand-finishing. Ra 0.05-0.2 µm — meets optical-grade standards. Reduces implant inflammation risk, improves optical performance and removes sharp edges.
Medical-Grade Quality & FDA Compliance
ISO 13485 quality management with full documentation and traceability. ISO 10993 biocompatibility, material certifications and process validation support FDA 510(k) submissions. Cleanroom manufacturing on request.
Optical-Grade Finishes & Dimensional Precision
Optical-quality finishes (Ra 0.05-0.2 µm) for fibre-optic connectors, lens mounts and optical instruments. Dimensional precision enables accurate optical alignment and minimal light loss.
Swiss-Type Single-Setup Production
Swiss screw machining turns and mills simultaneously, producing complete parts in one operation. Reduces secondary work, improves consistency and accelerates high-volume production of watch parts, connector pins and miniature fasteners.
High-Aspect-Ratio & Specialised Geometries
Machine high-aspect-ratio features (10:1 to 20:1): deep narrow slots, thin walls, intricate internal cavities. Micro-EDM enables features impossible with cutting tools.
Micro Machining Production Process
Design Analysis & Process Planning
Review CAD and specifications. Analyse features, tolerances, material and complexity to recommend optimal processes (micro-milling, Swiss turning, micro-EDM or combinations). Feasibility assessment flags challenges and optimisation opportunities.
Material Selection & Preparation
Source stainless, titanium, tungsten, ceramics etc. to spec. Material certs, chemistry and hardness verification ensure compliance. Stock prepared with proper grain orientation for optimal micro-machining.
Precision Setup & Tool Installation
Calibrate machine with micro-precision tooling. Work-holding with thousandths-of-a-millimetre repeatability. Thermal warm-up and calibration eliminate dimensional drift from temperature.
Micro Machining Production
Programs execute micro-milling, micro-turning or micro-EDM with real-time monitoring. Progressive depth-of-cut prevents tool breakage. Optimal coolant delivery. Operators monitor wear, vibration and dimensional drift.
Quality Control & Finishing
CMM verification, optical inspection for burr-free edges, surface finish measurement and hardness verification. Medical components receive biocompatibility testing and sterilisation validation. Full documentation.

Frequently Asked Questions
What is the smallest feature size you can machine?
Down to 0.05 mm (50 µm). For reference, a human hair is 0.07-0.1 mm — our capability rivals the finest precision manufacturing globally. Feature size depends on material, geometry and tooling.
What materials can be micro-machined?
Stainless steel (medical), titanium alloys, tungsten carbide, hardened tool steel, magnesium, brass, copper, beryllium (aerospace) and ceramics. Hard or brittle materials may require micro-EDM.
Are micro-machined components compliant with medical device regulations?
Yes. ISO 13485 manufacturing with full traceability and documentation. ISO 10993 biocompatibility, ASTM material testing and process validation support FDA 510(k) submissions. Cleanroom manufacturing available.
How does micro-machining cost compare to other processes?
Cost depends on complexity, quantity and material. Single prototypes cost more per unit (tooling amortisation); production runs scale down. Swiss screw machining offers excellent efficiency for high-volume intricate parts.
What tolerances can you consistently maintain?
Standard ±0.001" (±0.025 mm) across most features. Tighter ±0.0005" (±0.0127 mm) possible with optimised setups and extended cycle times. Ra 0.05-0.2 µm is inherent to the process.
Can you produce high-volume quantities?
Yes. Swiss screw machining is efficient for 100-500+ parts/day. For very high volumes (50 000+), we may combine with alternative processes for cost advantage.
