This site video is organized around the work assigned to a Huada permanent-magnet trimming machine: small-area stone cutting, irregular-block shaping and splitting, with structural concrete segmentation named as another application.
Small-area quarry cuts
The source places the machine in stone mines where a limited cut is needed. It does not state the cut size, stone or machine position used in the recording.
Irregular blocks
Shaping and splitting irregular material is the second named duty. The target geometry and finished dimensions are not preserved in the old page.
Concrete segmentation
Bridge and building concrete are also listed. That work has a different support and removal context from quarry block trimming, even when the cutting principle is related.
What “on site” does and does not establish
The title confirms that trimming is shown at a work site, but the archived text does not identify a customer, country, machine rating, wire or measured result. The video can serve as an application reference where the work is visible. It should not be used to claim a universal cutting rate or to combine quarry and concrete duties into one unchanged setup. A project record must name one material and target before performance is evaluated.
