Benefits of Micro Machining

Efficiency:

Micro parts can be fabricated quickly, it offers a solution of single process machining, which reduces the machines required and shortens the lead time.

Repeatability:

Micro machining can repeatedly produce small, intricate components with high precision and tight tolerances.

Increased Safety:

Micro machining’s micron level tolerances reduce the likelihood of part failure. The tight tolerances fit parts securely together and prevent safety hazards from broken or loose parts.

Increased Lifespan:

Micro machining tight tolerances also benefit component lifespan. When parts securely fit together, there’s less friction between them, and thus, less wear and tear, lending to a longer lifespan.

Versatility:

Micro machining is applicable for the production of both prototypes and parts with micro features, made from metals and plastics.

Quality Assurance for Micro Machining

To ensure the quality of our micro-machining processes, we use specialized validation methods capable of micron-level measurement. Our inspection systems are equipped with high-precision instruments whose resolution and accuracy are carefully matched to the manufacturing process requirements.

Optical measuring systems provide rapid non-contact assessment of two-dimensional features, offering efficient verification of critical dimensions. For comprehensive three-dimensional analysis, ultra-precision coordinate measuring machines (CMM) deliver exacting measurements of complex geometric tolerances and form characteristics. These systems validate part conformity to the most stringent dimensional requirements.

Advanced scanning technologies, including laser and white light scanners, enable complete digital capture of component surfaces through non-contact metrology. This capability supports full-field deviation analysis and facilitates reverse engineering of delicate micro-components. For the most detailed surface examination, scanning electron microscopy reveals microscopic structures and material characteristics that remain invisible to conventional inspection methods.
