Our specialized knowledge in micro component manufacturing sets us apart in the precision machining industry. We have dedicated equipment, processes, and personnel focused entirely on the unique challenges of producing parts at microscopic scales.
We excel at producing components with features so small they are barely visible to the unaided eye, yet must meet exacting precision standards.
1. Minimum structure size: 0.005mm — features smaller than the diameter of a human hair.
2. Minimum part size: 0.08 × 0.08mm — complete components smaller than a grain of table salt.
3. Minimum micro-rod diameter: 0.01mm — ultra-fine shafts for medical and electronic applications.
4. Minimum micro-hole: 0.003mm — precision micro-drilling at the edge of possibility.
Beyond micro-scale size, we also produce larger parts that require the same level of extreme precision in their critical features.
1. Maximum precision: 0.001mm on the highest accuracy parts we produce.
2. Fine surface finishes: Surface roughness as low as Ra0.05μm on precision-ground components.
3. Tight geometric tolerances: Flatness to 0.0003mm and roundness to 0.0005mm on critical features.
Manufacturing micro components with ultra precision requires a carefully orchestrated process that accounts for every variable that could affect dimensional accuracy at microscopic scales.
Every micro component project begins with thorough process planning to ensure manufacturability and quality from the outset.
1. Design review: Our engineering team reviews part designs for micro-machining feasibility and suggests optimizations.
2. Process selection: Choosing the optimal combination of machining technologies for each feature.
3. Tooling strategy: Selecting and preparing specialized micro-tools appropriate for the material and feature size.
Our micro component machining process follows a carefully sequenced workflow designed to maintain accuracy at every stage.
1. Material preparation: Careful selection and preparation of raw material stock appropriate for micro-scale processing.
2. Rough machining: Initial material removal with larger tools, leaving minimal stock for finishing.
3. Semi-finishing: Intermediate passes to bring features close to final dimensions while managing cutting forces.
4. Finish machining: Final precision passes using specialized micro-tools to achieve target dimensions and surface quality.
5. Post-processing: Surface treatments, deburring, and cleaning appropriate for micro-scale components.
At micro scales, even tiny cutting forces can cause significant part deformation. We have developed specialized techniques to manage this challenge.
1. Material science: Deep understanding of how different materials behave at micro scales under cutting forces.
2. Stress management: Strategic processing sequences and intermediate stress relief steps.
3. Custom fixturing: Innovative workholding solutions designed specifically for micro components.
4. Cutting parameters: Optimized feed rates, spindle speeds, and depth of cut to minimize forces.
