China' s Own Brand 28/16 Flexible Welding Platform/Worktable 1000*3000
Typical application scenarios
1.Automobile manufacturing: Body welding, chassis parts fixing
2.Construction machinery: Welding of structural parts of excavators and cranes
3.Rail transit: Welding of high - speed rail/subway car bodies
4.Aerospace: Assembly and inspection of aircraft parts
5.Mold industry: Positioning and adjustment of large - scale molds
Core features of the product
(1) Professional hole system design
D28 platform: The large aperture is suitable for positioning heavy workpieces and has strong impact resistance.
D16 platform: The small aperture provides precise fine - tuning ability and more accurate positioning.
(2) Advantages of the extra - long worktable
A length of 3000mm meets the needs of long workpieces such as tracks and beam frames.
A width of 1000mm ensures work stability.
(3) High - precision manufacturing
The worktable surface is processed by precision grinding.
Vibration aging treatment is carried out to eliminate internal stress.
Surface anti - rust treatment (plating or coating is optional).
