1000mm*1200mm*200mm 3D D28 Welding Table With Clamps
This welding workbench is a high-precision, modular welding and assembly platform. It adopts the D28 standard hole system, provides three-dimensional (3D) positioning capabilities, and is equipped with special fixtures. It is suitable for various industrial applications such as welding, assembly, inspection, and sheet metal forming.
Detailed Explanation of Core Parameters
1.Dimension Specifications
Length (L): 1000mm (1 meter)
Width (W): 1200mm (1.2 meters)
Height (H): 200mm (usually refers to the tabletop thickness or the overall height, and the specific design needs to be confirmed)
If it is the tabletop thickness: 200mm is an ultra - thick design, suitable for heavy - duty welding with strong anti - deformation ability.
If it is the overall height: it may refer to the vertical height from the workbench base to the tabletop, which is suitable for standing operations.
2.3D D28 Hole System
(1) D28 Standard
Hole diameter: 28mm (European standard, larger than the common 16mm or 22mm holes, suitable for fixing heavy - duty workpieces).
Hole pitch: Usually arranged at equal intervals of 50mm or 100mm (ensuring high - precision positioning).
Material: Usually made of high - strength cast iron or alloy steel, and quenched to improve wear resistance.
(2) 3D Design (different from ordinary 2D workbenches)
Tabletop: Covered with D28 positioning holes for XY - plane positioning.
Sides & End faces: Usually also have D28 holes, allowing the installation of fixtures or supports in the vertical direction (Z - axis).
Advantages: It can fix workpieces at multiple angles and directions, suitable for complex welding structures.
