D28 2000*1000mm Nitriding Welding Table With Clamps Devices Optional is a high-precision, modular welding tooling platform specifically designed for manufacturing processes such as metal welding, assembly, and inspection. Its core feature is the adoption of the D28 standard hole system (28mm pitch grid holes), and it undergoes nitriding treatment to improve surface hardness and wear resistance. Additionally, various fixtures (Clamps Devices) can be optionally equipped to achieve rapid positioning and clamping.
Core components
(1) Welding Table main body
Dimensions: 2000mm (length) × 1000mm (width), suitable for medium-sized workpiece processing.
Material: High-strength cast iron or alloy steel, quenched and tempered to ensure high rigidity and anti-deformation ability.
Surface treatment:
Nitriding: Nitriding at high temperature to form a high-hardness surface layer (up to HV800 - 1000), wear-resistant, corrosion-resistant, and extend service life.
Precision grinding: The flatness is usually controlled within 0.05mm/m² to ensure high-precision positioning.
(2) D28 hole system
Hole diameter: Standard Φ28mm (some models may come with M12/M16 threaded holes).
Hole pitch: 100mm×100mm equidistant grid, compatible with most standard fixtures.
Advantages:
Provide high-precision positioning (repeatable positioning accuracy up to ±0.02mm).
Support three-dimensional space expansion (fixtures can be installed in the X/Y/Z directions).
(3) Optional Clamps Devices
Common types of fixtures:
Toggle Clamps: Used for quickly fixing workpieces.
Dowel Pins: Ensure workpiece datum alignment.
Angle Plates: Used for complex-angle welding.
V-Blocks: Suitable for positioning cylindrical workpieces.
Magnetic Clamps: Used for quickly fixing ferrous materials.
