The Importance of Measurement of Mechanical Frames and Other Components
As a core part of the chassis, the frame must satisfy the following two critical requirements:
- Assembly Integration: Provide precise installation and positioning for the engine, suspension, transmission system, etc.
- Load Assurance: Ensure that frame deformation under extreme conditions does not cause part interference.
PMT Portable CMM Facilitates the Inspection of Agricultural Machinery Frame
As a high-precision portable coordinate measuring machine, the PMT portable measuring arm has emerged as an essential device for quality control in the agricultural machinery industry. The core application scenarios of the PMT portable measuring arm are as follows:
