What to Focus on When Selecting a CMM Manufacturer

From Procurement to Long-term Operation of a CMM: What to Check
A coordinate measuring machine involves multiple stages throughout its lifecycle, including model selection, installation, training, calibration, maintenance and upgrade. The overall capability of the manufacturer directly determines the full-lifecycle value of the equipment. When selecting a supplier, enterprises are recommended to evaluate four key aspects: whether the manufacturer owns its production factory, whether it has independent core R&D capability, whether it holds accredited calibration qualifications, and whether its after-sales network covers your region.
