CNC Machining

Tolerance requirements: The ISO 2768-m standard tolerance is ±0.1mm. To achieve high precision of ±0.01mm, cutting speed needs to be reduced and inspection frequency increased, significantly driving up costs.

Design complexity: Deep cavities, thin walls, small internal corners, and non-standard threaded holes all increase machining difficulty and tool change frequency.

Lead time: Rush orders require overtime or production rescheduling, which incurs expedite fees.

Certification requirements: Orders requiring certification documents such as IATF 16949 or ISO 13485 add administrative and inspection costs.

How to Get a More Reasonable Quote?

A few practical suggestions:

·Provide complete documentation: 3D models, 2D drawings, clear tolerances and surface roughness requirements, and material grades should be clearly specified (e.g., "Al 6061-T6" rather than just "aluminum")

·Loosen tolerances on non-critical dimensions, and only tighten precision on mating surfaces

·Use standard threaded holes and tool sizes

·Consolidate orders to spread setup costs across larger batch sizes
