Platform consists of riveting assembly platform, welding platform, platform, three welders. Riveting platform: the above processing has T-slots, mainly used for stationary work piece, is fitter workers are used to debug the equipment, assembly equipment, repair equipment, the basic platform. Welding platform: suitable for a variety of inspection, precision measurement of the reference plane, mechanical testing benchmarks for machine tools, inspection parts dimensional accuracy or disruptive behavior, and for precision marking, inspection of the machinery is also indispensable basic tool. Welder platform: platform marked with signs on the plane line, is fitter workers are used to test the workpiece, the workpiece reference marks using crossed lines mark line by the user according to their usage, making signs line the specific size. Riveting platform Material: high-strength cast iron HT200-300, face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years) use of the product accuracy and stability, wear performance.
