Our CNC Machining Processes
We offer 3/4/5-axis CNC milling for precision components and molds. We process metals and engineering plastics, supporting prototypes to mass production. Backed by ISO9001 standards, our services serve medical, automotive, aerospace and industrial sectors.
Our live-tool turn-mill machines accomplish turning, milling, drilling and tapping in one setup. We custom-make precision shafts, bushings and connectors with stable quality for batch orders.
Simultaneous 5-axis machining removes repeated clamping errors to fabricate intricate components in one run. Our process engineers provide DFM guidance to cut costs and shorten lead times for high-complexity parts.

Surface Finishing Options
Karry Precision provides a range of surface finishing services to improve the appearance, corrosion resistance, wear performance, cleanliness, and service life of CNC machined parts.
-
Anodizing
Anodizing forms a controlled oxide layer on aluminum surfaces, improving corrosion resistance, surface hardness, and wear performance. It also supports a wide range of colors for functional identification or decorative purposes.
-
Bead Blasting
Bead blasting uses fine abrasive media to produce a smooth, uniform, non-reflective surface. It helps reduce visible machining marks and creates a clean matte appearance without significantly affecting part dimensions.
-
Powder Coating
Powder coating applies a durable protective layer to metal surfaces through electrostatic spraying and heat curing. It provides strong resistance to corrosion, scratches, impact, and outdoor exposure.
-
Electroplating
Electroplating deposits a thin metallic coating onto the part surface to improve corrosion resistance, conductivity, hardness, or decorative appearance. Common options include nickel, zinc, chrome, and tin plating.
-
Polishing
Polishing reduces surface roughness and produces a smoother, brighter finish. Depending on the application, parts can be finished to a satin, brushed, or mirror-like appearance.
-
Passivation
Passivation removes free iron and surface contaminants from stainless steel, helping restore and strengthen its natural corrosion-resistant oxide layer without changing the part’s dimensions.

CNC Machining Tolerance Guide
Dimensional tolerance directly affects part fit, assembly performance, interchangeability, and manufacturing cost. Karry Precision evaluates tolerance requirements according to part function, material properties, geometry, machining method, and inspection conditions.
Proper tolerance planning can reduce unnecessary machining operations and improve production consistency:
- Apply tight tolerances only to functional or mating features
- Use general tolerances for non-critical dimensions
- Avoid unnecessary tolerance accumulation across assemblies
- Maintain consistent wall thickness where possible
- Allow suitable radii in deep pockets and internal corners
| Tolerance Category | Typical Tolerance | Suitable Materials | Cost Impact | Manufacturing Considerations |
| General Linear Dimensions | ±0.10 mm | Metals and engineering plastics | Low | Suitable for most non-critical dimensions using standard CNC milling or turning |
| Precision Linear Dimensions | ±0.05 mm | Aluminum, stainless steel, brass, steel and engineering plastics | Medium | May require precision tooling, controlled setups and in-process measurement |
| High-Precision Dimensions | ±0.02 to ±0.03 mm | Dimensionally stable metals and selected engineering plastics | High | Requires stable fixturing, controlled machining conditions and detailed inspection |
| Critical Features | Up to ±0.01 mm | Evaluated by material and geometry | High | Available for selected dimensions after engineering review; not applicable to every feature |
| Hole Diameter | ±0.02 to ±0.05 mm | Most machinable materials | Medium | Reaming, boring or precision drilling may be required for tighter hole tolerances |
| Hole Position | ±0.05 to ±0.10 mm | Metals and engineering plastics | Medium | Datum definition and inspection method should be clearly specified on the drawing |
| Surface Flatness | 0.05 to 0.10 mm | Primarily metal parts | Medium | Thin walls, large surfaces and residual material stress may increase deformation risk |
| Parallelism or Perpendicularity | 0.05 to 0.10 mm | Most machinable materials | Medium | Performance depends on datum selection, setup stability and feature spacing |
| Metric Internal Threads | Typically 6H | Metals and engineering plastics | Low | Standard fit for most general-purpose internal metric threads |
| Metric External Threads | Typically 6g | Metals and engineering plastics | Low | Standard fit for most general-purpose external metric threads |
