Products Description
We are the largest welding Table experts
The Welding Fixture Table is a high-precision, multi-functional, and compact specialized welding platform for industrial welding applications. It is primarily designed for toolrooms, laboratories, and small-batch precision machining scenarios, differentiating itself from large production line welding fixtures. Its core features include compactness, flexibility, higher precision, integrated functionality, and ease of operation. It is mainly used for manual welding, precise positioning welding, and prototyping of small metal parts, small molds, tooling and fixture components, and miniature parts. It is a core piece of essential equipment for toolrooms in machining workshops, R&D laboratories, and precision machining workstations.

Documentation: Includes bilingual (Chinese and English) operation manuals, precision test reports, and warranty cards, highlighting key precision parameters and maintenance points, suitable for independent use by overseas customers;
Core processing technology details
Laser cutting is used for blanking, resulting in burr-free edges and dimensional tolerances of ≤±0.1mm, laying the foundation for subsequent precision machining;
Tabletop heat treatment: The 45# steel tabletop undergoes tempering treatment (850℃ quenching + 550℃ tempering) + stress relief annealing, achieving a surface hardness of HRC45~50, eliminating internal stress and preventing deformation during later use; the cast iron tabletop undergoes artificial aging treatment to completely eliminate casting stress, ensuring long-term stability of flatness;
Precision machining: The core process is precision grinding using a CNC grinding machine. Tabletops with holes are first processed with CNC drilling and milling for small-sized hole systems (D28/D22/D16), and the hole walls are then precision reamed + hand-lapped, achieving a roughness of Ra≤1.6μm and a hole diameter tolerance of H6 grade, ensuring smooth and secure insertion and removal of locating pins; hole-less tabletops undergo mirror-finish grinding, achieving a flatness of ≤0.02mm/m, resulting in a mirror-like surface with no gaps when workpieces are placed on it;
Edge and groove processing: The T-slots/dovetail grooves on the tabletop are processed by CNC milling, with a groove width tolerance of ≤±0.01mm, ensuring perfect compatibility with clamping fixtures; all edges and corners are chamfered by CNC machining + hand polishing, with a radius of R3~R5, eliminating sharp edges and ensuring both safety and a comfortable feel;
Surface treatment process: Nickel plating/chromium plating uses a double-layer treatment of chemical plating + electroplating, with a plating thickness of 5~8μm, uniform and pinhole-free, providing splash protection, rust prevention, and scratch resistance; stainless steel tabletops undergo electrolytic polishing, achieving a surface roughness of Ra≤0.8μm, making them easy to clean and suitable for cleanroom environments;
Overall assembly and calibration: After the welding tabletop and base are assembled, a high-precision dial indicator + marble straight edge are used for overall calibration to ensure a tabletop flatness of ≤0.03mm/m. After successful calibration, a precision inspection label is attached, indicating the inspection data. Each device undergoes "individual inspection and individual qualification".
Common problems and quick solutions
Fault 1: Locating pin cannot be inserted/removed smoothly → Cause: Splatter/dust/rust on the hole wall → Solution: Clean with compressed air and a fine brush, apply a small amount of anti-rust lubricating oil;
Fault 2: Gap between the workbench surface and the workpiece → Cause: Slight tilt of the workbench/stains → Solution: Level the leveling feet with a spirit level, wipe off stains on the workbench surface with anhydrous ethanol;
Fault 3: Arc damage to the workbench during welding → Cause: Grounding clamp not connected/poor grounding → Solution: Clamp the pure copper grounding clamp onto the workpiece (do not clamp it onto the workbench), ensure good conductivity, lightly polish minor scratches with metallographic sandpaper and then apply anti-rust oil.
