Cast Iron Marking Plate is a fundamental tool used for precision marking and workpiece positioning in mechanical manufacturing, processing, and assembly. With its high flatness, stability, and wear resistance, it has become an important equipment in workshops and inspection processes. The following are its main uses and characteristics:
---
###* * 1. Core purpose**
1. * * Precise marking**
-Machining baseline: Draw machining contour lines, centerlines, hole position lines, etc. on the surface of the blank or semi-finished product to provide precise guidance for subsequent cutting and drilling.
-* * Complex Shape Marking * *: Using tools such as height gauges, marking needles, V-blocks, etc., multiple angle marking is performed on irregular workpieces (such as gears and crankshafts).
2. * * Workpiece positioning and adjustment**
-* * Spatial positioning * *: Determine the three-dimensional position of the workpiece through the platform plane and auxiliary tools (such as angle iron, square box) to ensure alignment during clamping or processing.
-Batch processing calibration: In batch production, unify the reference surface of the workpiece to reduce repeated adjustment time.
3. * * Detection Assistance**
-Pre check flatness: Verify the flatness or perpendicularity of the workpiece before marking to avoid marking errors caused by basic errors.
-* * Dimensional Verification * *: By combining marking with measuring tools, quickly verify whether the key dimensions of the workpiece meet the requirements of the drawing.
4. Assembly and Adjustment**
-* * Component Alignment * *: During the assembly process, use the platform plane to align components such as gears and bearing seats to ensure precise fit.
-Gap Adjustment: Use marking to assist in adjusting component clearances (such as sealing surfaces and guide rail clearances), optimizing mechanical performance.
5. * * Teaching and Training**
-* * Skill Training * *: Used in technical schools or corporate training to demonstrate the marking process and the use of measuring tools.
-Process simulation: Simulate actual production scenarios and guide students in mastering workpiece positioning and marking techniques.

###2. Core Features**
1. * * High plane accuracy**
-Made of HT200/HT250 cast iron, with aging treatment to eliminate internal stress, the flatness can reach * * Level 1 (± 0.02mm) or Level 2 (± 0.05mm) * * (according to GB/T 22095 standard).
2. * * Surface treatment optimization**
-Grid pattern or spot pattern: The surface is formed into fine patterns through scraping or grinding, which increases friction, prevents the workpiece from sliding, and facilitates clear and visible marking.
-Anti rust coating: Some platforms are coated with anti rust paint or plating to adapt to humid workshop environments.
3. Strong carrying capacity**
-Cast iron material has high compressive strength and can withstand the placement and marking operations of heavy workpieces such as large castings and machine tool bases.
4. * * Long term stability**
-Wear resistant and deformation resistant, suitable for long-term frequent use, and with proper maintenance, can maintain accuracy for decades.

###III. Typical Application Industries**
-* * Mechanical processing * *: Marking processing of machine tools, automotive parts, and hydraulic valve bodies.
-Mold manufacturing: Precise marking of mold parting lines and top pin hole positions.
-* * Heavy equipment * *: Outline marking of wind turbine blades and ship components.
-* * Maintenance workshop * *: Marking the repair baseline for damaged parts during equipment maintenance.
-Education and Research: Mechanical Technology Teaching, Laboratory Workpiece Preparation.

###4. Selection and Maintenance Suggestions**
1. * * Selection points**
-* * Size * *: Select the platform area based on the maximum workpiece size (common specifications: 500 × 400mm to 3000 × 2000mm).
-* * Accuracy level * *: Level 1 accuracy is used for high requirement detection and marking, while Level 2 accuracy is suitable for general workshops.
-Surface pattern: Grid pattern is suitable for fine marking, and spot pattern is more anti slip.
2. * * Precautions for use**
-Handle the workpiece with care: Avoid heavy objects hitting the surface of the platform to prevent scratches or deformation.
-* * Regular cleaning * *: Timely remove iron filings and oil stains to maintain surface cleanliness.
-Rust prevention treatment: Regularly apply rust proof oil, especially in rainy or humid environments.
The cast iron marking platform is a key link in mechanical manufacturing that connects design drawings with physical processing. Its high precision, stability, and ease of use make it an indispensable tool in the workshop. Reasonable selection and standardized maintenance can significantly improve the efficiency and processing quality of marking, especially in mass production and complex workpiece processing, with outstanding value.
