Huada's archived description presents a new-generation double blade stone-cutting machine as a drive-and-structure package: permanent-magnet speed control, two large saw blades and four-axis transmission. These are presented as parts of one machine rather than separate options.
Permanent-magnet drive
The machine uses a permanent-magnet motor with frequency-conversion speed regulation. Huada links this arrangement with efficiency and energy saving, but no electrical comparison is published.
Double-blade cutting arrangement
Two large saw blades are named. Their diameter, spacing, segment and usable cutting geometry do not appear in the old page.
Four-axis transmission
The transmission and stable structure are presented together as machine features. The source does not provide an axis diagram, guide arrangement or tolerance.
Stone range and evidence limit
Granite and marble are the examples given for mining use, followed by a broader reference to various stone. A configuration for one material cannot be inferred for the other from this short description. The video can introduce the machine form and named drive technology; it cannot establish energy savings, cut quality or output without a baseline. Selection still requires the actual stone, planned bench and supplied machine specification.
