The labor cost is higher and higher, and the management is more and more difficult. The former labor cost is cheaper than the machine, and the machine is cheaper than the labor. Only by improving the quality and reducing the cost can the core competitiveness of the enterprise be improved. The manual vision measuring machine can find the defective parts in each stage of the production process. The defective parts will be directly removed from the earliest production process, no longer continue to carry out accurate processing, which saves the cost.Sometimes, the defective parts can be put into the production process again for repair or grade treatment. This also saves the material, no matter how defective products will not enter the subsequent processing process, to prevent the additional costs of subsequent production.
