Product Overview
High Quality D28 D16 Cast Steel Welding Table is a professional - grade welding work platform, designed specifically for high - precision welding, assembly, and manufacturing operations. This type of workbench is widely favored in the metal processing industry for its excellent stability, durability, and versatility.
Main features
1. Material and structure
D28/D16 cast steel: Manufactured from high-strength cast steel materials, with D28 and D16 representing different hole type specifications (28mm or 16mm in diameter)
Heat treatment process: Through special heat treatment, it provides excellent anti-deformation ability and wear resistance
Heavy design: Usually has a relatively thick tabletop (25 - 40mm) to ensure stability during operation
2. Modular hole system
Standard hole pitch: A precisely arranged hole array, usually with an integer multiple spacing of 50mm, 100mm, or 200mm
Multi-functional fixture compatibility: Can be used in conjunction with various fixtures, positioners, and clamping devices
Three-dimensional positioning: Allows for precise workpiece positioning in the X, Y, and Z directions
3. Surface treatment
Precision machining: The tabletop is milled and ground to ensure flatness (usually ≤0.1mm/m²)
Rust prevention treatment: May include galvanizing, blackening, or special coating treatment to improve corrosion resistance
High temperature resistance: The surface can withstand welding spatter and high temperature effects
