How to choose diamond segment sintering graphite mold?

Sintering graphite abrasive tool is one of the important tools for making diamond segments, and it needs to have certain production standards to ensure its quality and performance. Here are some common production standards:
1. Selection of graphite materials: high-purity, fine-grained, and low-ash graphite materials are required for making sintering graphite abrasive tools.

2. Preparation of graphite blanks: graphite blanks need to be screened, washed and dried to ensure the purity and quality of the blanks.

3. Processing of graphite blanks: graphite blanks need to be processed by turning, milling, grinding, etc. to make the shape and size of the abrasive tool.

4. Control of sintering process: the production of sintering graphite abrasive tools requires a high-temperature and high-pressure sintering process, and strict control of parameters such as pressure, temperature, and time is required to ensure the compactness and stability of the abrasive tools.

5. Subsequent processing and testing: after the production of sintering graphite abrasive tools, subsequent processing processes such as surface treatment, grinding, cleaning, etc., and testing of hardness, density, size, etc. are required to ensure the quality and performance of the abrasive tools.

In short, the production of sintering graphite abrasives needs to be carried out in strict accordance with certain production standards to ensure that the quality and performance of the abrasives meet the requirements.

So how should the segment factory choose better quality graphite abrasives?

The following aspects need to be paid attention to when choosing a better quality graphite abrasive tool:

1: Material: choose high-quality graphite material to ensure its mechanical properties and wear resistance.

2: Manufacturing process: the sophistication of the manufacturing process of graphite abrasive tools directly affects its quality. High-quality graphite abrasive tools should go through a strict manufacturing process, including multiple processes such as material selection, pretreatment, processing, sintering, and cooling.

3: Equipment precision: the manufacture of graphite abrasive tools requires the use of high-precision equipment, including processing equipment, measuring equipment, etc. Only graphite abrasive tools manufactured with high-precision equipment can meet the requirements.

4: Quality control: strict quality control measures are required in the manufacturing process, including quality inspection, records, etc., to ensure the consistency and stability of the product.

If a simple identification process is adopted, it is generally divided into four steps:
1) Cracks: it can be observed with the naked eye or with a magnifying glass. Cracks in graphite tools may be distributed throughout the tool or may be localized in certain areas. When a crack is found on an abrasive tool, it should usually be taken out of service and replaced.

2) Bubbles: use the naked eye or a magnifying glass to observe the surface of the graphite abrasive tool. Bubbles usually look like small holes on the surface, and the arrangement is relatively random. When bubbles appear on the surface of graphite abrasives, they often affect the cutting performance and need to be replaced.

3) Inclusions: inclusions on the surface of graphite abrasives may look like black spots or small particles. These inclusions can negatively affect machinability and should be replaced.

4) Uneven surface: we can use the naked eye or a magnifying glass to observe the surface of the graphite abrasive tool. If the surface is found to be uneven, uneven or irregular, it may affect the cutting accuracy and needs to be replaced.
To sum up, choosing a graphite abrasive tool with better quality requires comprehensive consideration in terms of material, manufacturing process, equipment accuracy and quality control. When selecting a graphite grinding tool supplier, the segment factory should carefully evaluate the supplier's comprehensive capabilities and manufacturing level to ensure the purchase of high-quality graphite grinding tools.
