Polishing/Buffing
Refine surfaces with abrasives/polishes to enhance smoothness, shine, and remove minor imperfections.
Passivation
Removes free iron contaminants and enhances stainless steel’s corrosion resistance.
Sandblasting/Shot Peening/Bead Blasting
Use particles (sand, shots, beads) to clean, texture, or strengthen surfaces via high-velocity impact.
PVD (Physical Vapor Deposition) Coating
Physical vapor deposition forms thin, hard films (e.g., metals, nitrides) on surfaces for wear, corrosion resistance, and aesthetics.
Chemical Conversion Coating
Forms protective films via chemical reaction on metal surfaces, enhancing corrosion resistance and paint adhesion.
Electroplating (e.g., Nickel, Chrome, Zinc)
Deposits metal layers onto substrates via electrolysis, improving appearance, wear and corrosion resistance.
Electropolishing
Smooth metal surfaces by removing surface material, enhancing shine and corrosion resistance.
Heat Treatment
Controlled heating/cooling of materials to alter properties like hardness, ductility, or strength.
Painting (e.g., E-Coating)
Applying liquid coatings (paints) to surfaces for protection, decoration, or corrosion resistance via brushing/spraying.
Laser Marking
Using laser beams to engrave permanent marks (text, logos) on surfaces with high precision and minimal damage.
Special CNC Machining
Precision Swiss Machining
Swiss machining represents the pinnacle of precision for small, complex components where tolerances and surface finish are critical.
At Fecision, we've mastered this specialized process to deliver exceptional results across medical, aerospace, automotive, and electronics applications.
Tight Tolerances
Our Swiss machining capabilities routinely achieve tolerances of ±0.0001" (2.5 microns) on diameter and ±0.0002" (5 microns) on length, with surface finishes as fine as 16 Ra microinches. For specific applications, even tighter tolerances may be possible.
Material Selection
Material selection significantly impacts Swiss machining results. The process requires high-quality bar stock with consistent diameter and straightness. Our materials experts can recommend optimal materials for your application, balancing machinability, mechanical properties, and cost considerations.
Whether you’re designing a new product that requires tight-tolerance components or looking to improve an existing design, our Swiss machining expertise can help you achieve superior results. Our engineering team works closely with you from concept to completion, ensuring your parts meet or exceed specifications while optimizing for manufacturability and cost-effectiveness.

CNC Machining Design Guidelines
General Design Recommendations
- Design with uniform wall thickness when possible
- Avoid sharp internal corners; use fillets with minimum radius of 1/3 the depth
- Maintain minimum wall thickness of 0.8mm (0.031″) for metals and 1.5mm (0.059″) for plastics
- Design parts to be machined from standard stock sizes
- Consider tool access and workholding requirements
Feature-Specific Guidelines
- Minimum hole diameter should be at least 1/3 of the depth
- Maintain minimum thread engagement of 1.5× the diameter
- Avoid deep pockets with small corner radii
- Design undercuts to be accessible by standard tools
- Specify critical dimensions and tolerances clearly

Start CNC Machining
Submit Technical Files
xport your design to a CNC-compatible CAD format. For CNC machining, we advise STEP format as it’s more standardized and can be used across platforms. A technical drawing is helpful, especially for threads, tolerances, or specific finishes.
DFM & Quotation
Our engineers analyze your design for manufacturability, check tolerances and materials. Please be aware that further discussions may be needed during the process. We then provide a detailed quote including lead time, costs, and other infomation you may need.
Precision Manufacturing
Upon your confirmation to the design, our team will begin CNC machining. Using advanced CNC machines, we mill, turn or grind parts per your design. Real-time monitoring ensures adherence to tolerances, with material traceability maintained throughout production.
Inspection & Delivery
Parts undergo strict QC via CMM or 3D scanning. We issue inspection reports, pack securely and ship, offering tracking info. Rush delivery options are available upon request.
