Application of cast iron flat plate

1、 Core functions

1. Geometric tolerance detection benchmark

Used to check the geometric tolerances such as flatness, straightness, parallelism, etc. of mechanical components.

Cooperate with tools such as dial indicators and micrometers to achieve high-precision measurement.

2. Precision machining and assembly

As a reference plane for mechanical processing, tool workshops, and machine repair workshops.

Support grinding, polishing and other processes to ensure surface accuracy during processing.

3. Industrial quality control

Suitable for industries such as mechanical manufacturing, hardware, aerospace, automotive, electronics, printing, and instrumentation.

Ensure product size consistency and reduce scrap rate.

2、 Typical application scenarios

1. Mechanical component inspection: measure the flatness and straightness of workpieces such as shafts and boxes.

2. Machine tool guide rail calibration: Verify the parallelism of the machine tool guide rail to ensure machining accuracy.

3. Mold manufacturing: As the benchmark for mold parting surface, it ensures the accuracy of mold closure.

4. Electronic component assembly: Check the flatness of the printed circuit board (PCB) to avoid welding deformation.

5. Precision instrument calibration: Calibrate the installation benchmarks for precision equipment such as optical instruments and sensors.

3、 Key parameters

1. Material: HT200-40 high-strength cast iron, hardness HB170-240

2. Accuracy level: 0-3 levels (flatness tolerance level 0 ≤ 0.003mm/m, level 3 ≤ 0.1mm/m)

3. Structural form: Reinforced plate/box type, the working surface can process V-shaped/T-shaped/U-shaped grooves and holes.

4. Specification range: Conventional size 100 × 100mm~12000 × 3000mm, supports non-standard customization.

5. Surface treatment: Scraping process (grades 1-3) or precision grinding (grade 0), roughness Ra ≤ 0.8 μ m.
