The ultimate presentation of mechanical aesthetics
In the modern production workshop of Qingdao Puhua Heavy Industry, the latest hook-type shot blasting machine is waiting for the final surface treatment in its original metal state. This unpainted "bare metal" state provides us with a rare opportunity to directly appreciate the precise structure and excellent workmanship of high-end industrial equipment. From every welded seam to every machined surface, these equipment show amazing mechanical beauty.
A visual feast of precision manufacturing
Looking closely at these unpainted equipment, you can see:
Surface treatment process
After sandblasting pretreatment, the surface roughness of all large structural parts is strictly controlled within Ra12.5μm
The key load-bearing parts adopt double-sided welding technology, and the welds are tested by ultrasonic flaw detection with a pass rate of 100%
The surface finish of castings and non-standard machined parts reaches ▽4 level standard
Tolerance control system
The coaxiality error of the hook rotating axis is ≤0.03mm/m
The dynamic balance accuracy of the shot blasting machine impeller is G2.5 level, and the residual imbalance is <1g·cm
Complete machine assembly After that, the clearance of each moving part is controlled within the range of 0.05-0.1mm
Technical parameter highlights
Maximum workpiece size: diameter 2.5m × length 6 m
Shot blasting capacity: 600kg/min (adjustable)
Dust removal efficiency: ≥99.8%
Equipment noise: ≤82dB(A) (measured at 1m from the equipment)
Expert perspective
"Observing industrial equipment in an unpainted state is like admiring an unfinished sculpture," said the chief engineer of Qingdao Puhua Heavy Industry. "Every detail directly reflects the manufacturer's craftsmanship and quality awareness. The processing accuracy and assembly quality demonstrated by this batch of equipment represent the latest level of high-end equipment manufacturing in China."
