Surface Nitrided 3D D28 Welding Table Three-dimensional Welding Platform
(1) D28 Heavy-duty Hole System
• Large aperture for heavy-duty fixtures: The 28mm aperture can accommodate bolts of M24 - M30 specifications, directly fixing large workpieces or hydraulic fixtures, avoiding the secondary reinforcement problem caused by the small aperture of traditional welding platforms.
(2)Deep Nitriding Surface Treatment
• Self-cleaning Feature: The surface of the nitriding layer is dense and smooth, making it difficult for welding slag and metal chips to adhere, reducing downtime for cleaning.
-
(3) Three-dimensional omnidirectional clamping ability
• Stereoscopic fixture network: Through the linkage of side holes, bottom T-slots and top hole systems, it supports 360° multi-sided synchronous fixing of workpieces (such as pipe fitting welding, frame assembly).
(4) Design of Anti - Deformation Structure
• Honeycomb Reinforcement Rib Substrate: The internal honeycomb - shaped support structure is adopted, which reduces the weight by 20% while improving the flexural rigidity, and ensures no deformation during long - term use.
