Cast Iron PlateGB/T22095-2008It is a flat datum tool used for workpiece inspection or marking. 

Cast iron plates have a wide range of applications, used in industries such as mechanical manufacturing, chemical engineering, hardware, aerospace, petroleum, automotive manufacturing, and instrument manufacturing. Cast Iron Plate: Primarily used as a reference for inspecting workpiece errors, inspection plate/The inspection platform plays a crucial role in the mechanical manufacturing process. It is essential for inspecting each workpiece before it leaves the factory.   Basic benchmark tools.

Cast iron plates are divided into ribbed and box-type according to their structure, while rock plates are categorized into flanged and unflanged types.

Cast iron plates are categorized by their applications into types such as inspection plates, marking plates, assembly plates, riveting and welding plates, sand-blasting plates, etc. They are also classified by their accuracy grade levels into...1、2、3Grade flat plate, rock flat plate available000Grade, where2Level A and above is for inspection tablets.3Grade marked underlined flat.

After wear, cast iron plates can be reground to restore their precision.

Cast iron plates can be inspected for flatness using the coloring method, offering the advantages of accuracy, intuitiveness, and convenience. Moving the table and workpiece over the ground cast iron plate is smooth with no feeling of stickiness, facilitating measurement and enhancing accuracy.

The cast iron quality and heat treatment of the cast iron plate greatly affect its performance: it may cause deformation of the working surface due to residual high internal stress; it may prevent the maintenance of precision due to wear; or it may result in a roughness with a large number due to the difficulty of scraping. Therefore, the use of cast iron plates   Be mindful of the selection of cast iron materials and the use of methods like aging treatment to reduce residual stresses in cast iron plates.

Technical requirements for cast iron plates

1The flat working surface must not have any defects such as sand holes, gas holes, cracks, inclusions, shrinkage, scratches, dents, and rust spots that significantly affect appearance and performance.

2The casting surface of the tablet should be clear of sand and smooth, with paint that is firmly adhered.

3Precision Grade:0Grade~3On a high-grade flat work surface, diameter less than15mmThe sand holes can be plugged with the same material, with a hardness less than that of the surrounding material. The number of sand holes plugged on the working surface should not exceed4Each, and the distance between sand holes should not be less than80mm。

4Flat panels should be used.   Manufactured from fine gray cast iron and other materials, the working surface hardness should be170~240HB。

5The flat working surface is typically finished by scraping. For surfaces finished by scraping processing.3Graded flat work surface, with a roughness textureRaAllowed values:5μm。

6The tablet should undergo demagnetization and stability treatment.

7On the two side surfaces of the flat panel, there should be threaded holes (or cylindrical holes) for installation handles or lifting rings, and the design of the device position should be optimized to minimize deformation caused by handling.

8If threaded holes (or grooves) are set on the tablet's working surface, their location should not exceed the working surface level.

Cautionary Notes for Cast Iron Plates

The tablet requires installation and debugging before use. Then, clean the working surface of the tablet and use it only after confirming there are no issues. During operation, be cautious to avoid aggressive collisions between the workpiece and the tablet's working surface to prevent damage to the tablet; the weight of the workpiece   Do not exceed the tablet's rated load, as this may lead to reduced work quality and potentially damage the tablet's structure, causing deformation and rendering it unusable.

How to evaluate the contact spots on machined cast iron plates during calibration

Cast iron plates are essential tools widely used in the mechanical industry for testing, inspection, and marking. To extend the service life of cast iron plates, utilize precision.The surface finish of lapped contact spots is an important technical indicator for cast iron plates.

Cast Iron Flat Plate Maintenance

1To prevent deformation of the cast iron plate, when lifting the cast iron plate, use four identical-length steel wire ropes to simultaneously hang onto the four lifting holes on the cast iron plate, and securely hoist the cast iron plate onto the transportation vehicle.

2Ensure cast iron plate support points are properly padded and leveled, with even distribution of force at each support point, resulting in a stable cast iron plate overall.

3Ensure that the iron cast flat plate is properly installed by using adjusting pads to securely and firmly support all the plate's support points, and then adjust the iron cast flat plate to the required precision by a technician.

4Handle workpieces gently when using cast iron plates; avoid moving rough workpieces on the cast iron plate to prevent磕碰, scratches, or other damage to the working surface.

5To prevent overall deformation of the cast iron plate, remove the workpiece from the cast iron plate after use to avoid prolonged pressure from the workpiece causing deformation of the cast iron plate.

6When not in use, clean the working surface of the cast iron plate promptly, then apply a layer of rust-proof oil and cover it with rust-proof paper. Seal the cast iron plate with its outer packaging to prevent accidental damage to the working surface.

7Cast iron plates should be installed in a well-ventilated and dry environment, and kept away from heat sources, corrosive gases, and corrosive liquids.

8Cast iron flat plate   Standard implementation is subject to regular weekly inspections, with the inspection cycle varying according to specific circumstances.6-12Month(s).
