CNC machining of small parts - Comprehensive quality inspection

When CNC machining small parts, the dimensional accuracy of the small parts (e.g., ±0.001 mm), surface defects (e.g., scratches, dents), and burr residues must be inspected using magnification equipment.

Inspection tool selection:

1: Optical microscope: magnification 10–100x, used to observe surface burrs, scratches, and edge flatness.
2: Metallographic microscope: Magnification range of 50–500x, suitable for inspecting microstructures or micro-cracks (e.g., defects caused by processing stress).
3: Tool microscope/image measuring instrument: Combines optical imaging with software analysis to precisely measure dimensions (e.g., length, angle, hole diameter) and automatically determine compliance with tolerance requirements, suitable for batch inspection.

With the assistance of the above magnification tools, we can ensure that the processing accuracy and edge quality of small parts meet requirements while strictly controlling product.

Regardless of size, we must ensure perfect delivery of every product!
