Swiss CNC Machining
Precision machining of small, intricate plastic components with high accuracy and repeatability. Ideal for medical, aerospace, and electronics applications requiring tight tolerances.
CNC Milling (3-Axis,4-Axis& 5-Axis)
High-precision milling for complex geometries, pockets, and surfaces. Supports prototypes and production parts across multiple industries.
CNC Drilling
Precision drilling of plastic components to create accurate holes for assemblies and functional features.
CNC Grinding
Precision grinding of plastic surfaces to achieve tight tolerances, smooth finishes, and exact dimensional specifications for critical components.
Tolerances Of Plastic CNC Machining
Xtproto delivers high-precision CNC plastic machining with tight dimensional tolerances and excellent repeatability. Standard tolerances are typically maintained at ±0.01 mm, while tighter tolerances of up to ±0.005 mm can be achieved depending on material type and part geometry. Our advanced multi-axis CNC equipment allows machining of fine features as small as 0.2 mm, while optimized cutting parameters help achieve smooth surface finishes typically ranging from Ra 0.8 to 3.2 μm. Each component is inspected through strict quality control procedures to ensure consistent dimensional accuracy for both prototypes and production parts.
Xtproto’s quality assurance goes beyond basic checks — we use a structured inspection process from start to finish to ensure every plastic part meets your exact requirements. Upon arrival, raw materials are verified before machining begins. During production, key features are monitored at defined checkpoints using advanced metrology tools such as coordinate measuring machines (CMM) and precision optical measurement systems.
We offer multiple levels of verification reports, including dimensional inspection reports, first article inspection (FAI), and certificates of conformance, enabling traceability and conformance documentation tailored to your needs. All finished parts undergo thorough final inspection, ensuring critical dimensions, tolerances, and surface criteria are verified before shipment. Our in‑house quality controls, calibrated equipment, and documented procedures deliver consistent performance and measurable confidence for every job.
