Bending specifications: 200 × 200 mm 300 × 200 mm 300 × 300 mm 400 × 300 mm 400 × 400 mm 500 × 400 mm 500 × 500 mm 800 × 600 mm, shaped product specifications: according to customer drawings or both sides to work out production .3. the use of plate bending machine: the machine is crossed bending test an indispensable tool for measuring tooling, machinery and test measurement, check the dimensional accuracy of parts, disruptive behavior, and make a dash, etc.; cast iron bend board is mainly used for testing, installation, vertical machine mechanical inspection, testing plate bending can also check the workpiece in the vertical, rectangular plate bending machinery and equipment for precision inspection and machine inspection between vertical implementation Standard 4. iron bending of the technical parameters include: the carrying bending, bending length and breadth, precision bending of the surface, bending the weight, bending the material requirements, etc. 5. cast iron plate bending Caution: First, the bending of the face to wipe clean, no problem in identifying the circumstances under bending and then bending into the cast iron flat work surface, re-use precision tuned addition of cast iron plate bending is electronics industry, machinery manufacturing machine tools indispensable measuring gages, do not have corrosion, moisture, temperature too high or too low circumstances.
