CNC engraving and milling machines rely on vacuum pumps to generate strong suction force to fix wood workpieces, avoiding surface damage from physical fixtures. Dry rotary vane pressure pump provides stable negative pressure (vacuum degree up to -80kPa) to ensure cutting accuracy; Designed to withstand sawdust and extend lifespan, combined with frequency conversion technology to automatically adjust power according to workpiece size, reducing energy consumption by 25%. In customized furniture processing, the vacuum suction cup system supports efficient processing of irregular parts and reduces waste rates.
