The D28 3D Welding Table with HRC60 hardened alloy tool steel surface is a heavy-duty, high-precision, and long-lasting modular 3D welding/fixturing platform. Its core features include Φ28mm standard positioning holes, a 100mm equidistant grid, CNC precision machining, and an HRC60 grade hardened alloy tool steel surface. It is specifically designed for heavy workpiece welding, fixture assembly, and robotic welding integration, making it a core tooling equipment for industries such as automotive, construction machinery, mold manufacturing, and rail transit.

In addition to standard sizes, the D28 3D Welding Table with HRC60 hardened alloy tool steel surface supports custom dimensions (length × width × thickness) to meet the welding needs of extra-large/irregular heavy workpieces. Customization takes 15-30 days.

The D28 3D Welding Table with HRC60 Hardened Alloy Tool Steel Surface is a high-end, heavy-duty equipment. It undergoes 100% comprehensive factory testing, and each finished product comes with a test report and certificate of conformity. The testing covers four core dimensions: accuracy, hardness, load capacity, and compatibility, as follows:

• Hardness Test: The surface hardness of the table is tested using a Rockwell hardness tester. At least 5 random points are tested on each table, and the hardness must be ≥HRC58, with an average of HRC60±2;
• Geometric Accuracy Test: A coordinate measuring machine (CMM) is used to test the flatness, perpendicularity, hole position tolerance, and center distance of the table surface. All indicators must meet the standards;
• Load Capacity Test: The table undergoes a static overload test (loaded with 1.5 times the rated load and left for 24 hours). The table must show no deformation or cracks;
• Fixture Compatibility Test: Standard D28 fixtures are installed to test the smoothness of insertion and removal, and the positioning accuracy. Repeatable positioning accuracy ≤0.03mm;
• Levelness Test: A laser level is used to test the overall levelness of the table, with an error ≤0.05mm/m²;
• Bracket Strength Test: The bracket undergoes a vibration test (simulating welding vibration for 2 hours). The bracket must show no loosening or deformation;
• Appearance Inspection: The table surface is inspected for dents, chipping, and scratches, and the bracket is inspected for paint defects and welding defects. The completeness of accessories is also checked;
• Splicing Accuracy Test (for multi-unit splicing models): After splicing, the overall flatness and height difference are tested, with an error ≤0.08mm/m².

Select specifications based on demand: Base your selection on workpiece weight/size, welding accuracy, and usage frequency. Avoid blindly choosing heavy-duty models (which increase costs) or under-specifying with standard models (which won't meet production needs);

Prioritize precision: For automated welding/precision fixturing applications, prioritize 50mm grid spacing + precision-ground tabletop; for general heavy-duty welding, choose 100mm grid spacing to balance efficiency and cost;

Compatibility principle: Prioritize standard D28 hole patterns for compatibility with internationally available fixtures, avoiding limitations on future accessory purchases;

Long-term use principle: For high-frequency use/harsh environments, always choose an HRC60 alloy tool steel tabletop. This single investment will reduce long-term maintenance costs.
