Single crystal synthetic diamonds

Single crystal diamonds are crystalline structures formed through covalent bonding with saturated, highly directional bonds. They possess exceptional hardness and wear resistance, making them a highly cost-effective option for processing a wide range of materials. These diamonds deliver fast material removal rates while achieving superior surface finishes.

Polycrystalline synthetic diamonds 

Polycrystalline synthetic diamonds have a structure similar to natural diamonds, formed by the aggregation of spherical microcrystals. They are highly effective for processing a wide range of materials and are especially well-suited for superhard ceramics and sintered carbides.

Unlike single crystal diamonds, polycrystalline diamonds feature more crystal edges and grinding surfaces, with each edge capable of cutting. This increases the likelihood of diamond-to-sample contact, greatly improving grinding efficiency. They also demonstrate outstanding toughness and self-sharpening characteristics. During grinding, larger particles break down into smaller ones, preventing the formation of sharp edges that could cause scratches on the workpiece surface.

As a result, polycrystalline diamonds are less likely to produce surface scratches compared to single crystal diamonds, making them ideal for applications requiring both precision and surface protection.

Metallographic Polishing Lubricant

Polishing is the final step in material preparation. Under pressure in a grinding and polishing machine, heat and friction can occur, often leading to scratches or deformation in the metallographic structure. To minimize these effects, it is recommended to use a smooth, soft polishing cloth along with a polishing lubricant containing nanoscale particles.

Our latest series of polishing lubricants provide excellent lubricity, effectively reducing thermal damage and delivering a clean, high-quality surface finish. Their strong dispersing action ensures abrasives remain evenly distributed across the polishing cloth, accelerating the grinding and polishing process.

• Blue Formula: Ideal for precision grinding and diamond polishing of all materials.
• Red Formula: Specially designed for the final polishing of non-ferrous metals and softer iron-based alloys.

Instructions for Use

• Semi-automatic or fully automatic machines
  Pour the liquid into an FY-5 dropper bottle and set the dropper flow rate parameters. The lubricant will automatically drip onto the polishing cloth, providing both lubrication and cooling during polishing.
• Manual polishing
  Pour the liquid into a soft plastic bottle with a nozzle (such as a wash bottle). Start the grinding and polishing machine, then gently squeeze the bottle to spray the lubricant and cooling liquid onto the cloth. Once the entire polishing surface is evenly wetted, polishing can begin.
• Additional lubrication
  If resistance increases during grinding or polishing, apply a moderate amount of lubricant and cooling liquid as needed.

Anti-Adhesion Disc

The surface of the non-stick plate is specially treated to reduce adhesive residue when using adhesive-backed polishing cloths or metallographic sandpaper, ensuring greater convenience and efficiency. It is also compatible with magnetic pads, allowing for quick switching between different polishing media.

Magnetic adhesive pad

The magnetic backing pad enables fast and easy switching between polishing cloths or metallographic sandpapers. When working with different metal samples, variations in polishing powders, precision requirements, and material hardness can make changing and securing polishing cloths both inconvenient and wasteful.

By using a magnetic backing pad to hold polishing discs, the process is greatly simplified. Preparing multiple non-stick pads with different polishing cloths or sandpapers attached allows for quick, efficient replacements, saving both time and materials.

Diamond Abrasive Disc

The diamond abrasive disc delivers strong cutting power and high efficiency, achieving excellent polishing results. Its durability and long lifespan make it a complete replacement for traditional sandpaper.

The raised resin surface design improves debris removal, preventing contamination and producing a smoother sample finish. The resin layer is densely embedded with diamond micropowder, providing sharper cutting edges for efficient removal of surface deformation from earlier stages.

The disc’s grinding ability is regenerative—when used with a diamond suspension polish, it restores its original cutting power.

Metallographic Sandpaper

Metallographic sandpaper is a traditional consumable used to grind specimens to the required section while gradually removing surface deformation layers.

Three Key Factors Defining Sandpaper Quality

• Grinding Efficiency
  Made with advanced abrasives such as aluminum oxide and silicon carbide, and with tightly controlled grit sizes, the sandpaper delivers excellent grinding efficiency, reduces processing time, and ensures a more uniform deformation layer.
• Economic Durability
  Advanced sand-coating techniques extend the service life of the sandpaper, providing greater durability and cost-effectiveness.
• Warp Resistance
  The sandpaper demonstrates strong resistance to water warping. After wet grinding, it remains flat with minimal curling, ensuring consistent surface contact between the specimen and abrasives.

Polishing Fabric

The spaces between fabric fibers hold polishing micro-powder, allowing partial exposure of the abrasive to create a grinding effect. These gaps also retain lubricants, helping maintain proper lubrication and preventing overheating of the sample surface. The wet friction between the fibers or fabric nap and the sample surface produces a smoother, brighter finish.

Polishing fabric selection depends on the hardness of the material being processed:

• Soft materials: Use soft, thick polishing cloths.
• Hard materials: Use compact, thin polishing cloths.

Our precision polishing fabrics are designed with carefully selected materials to ensure excellent compatibility with abrasive particles. This enhances abrasive retention, increases durability, and improves polishing efficiency.

Cutting and Sampling

The sample preparation process consists of several key steps, each requiring precision to ensure reliable results. In metallographic analysis, preparation generally involves four stages:

• Cutting and Sampling
• Embedding Samples
• Mechanical Sample Preparation
• Sample Inspection

Cutting and sampling is the first stage, where the specimen is separated from the bulk material and trimmed to the appropriate size for further processing. This step is critical to preserve the structural integrity of the sample and minimize deformation that could affect subsequent analysis.

Inlaid Sample

For metallography, the most suitable cutting method is wet wheel cutting, as it minimizes damage while maintaining efficiency. The cutting blades used are composed of abrasive material and adhesive, and their composition should be selected based on the hardness and toughness of the material being cut.

Choosing the appropriate blade ensures minimal surface deformation, good flatness, and faster preparation of samples with reliable results.

Grind

The sample is embedded in resin to improve handling and enhance the overall quality of preparation. Embedding is essential for specimens that require edge or surface protection.

Before embedding, the sample must be thoroughly cleaned to remove contaminants and ensure proper bonding between the specimen and the resin.

Embedding methods are generally divided into two types:

• Hot Embedding: Best suited for processing large batches of samples. It produces specimens of high quality with uniform size and shape in a short time. Hot embedding resin is typically more cost-effective, but it requires an embedding machine.
• Cold Embedding: Ideal for processing multiple samples at once or for individual specimens. Cold resin can also be used with vacuum impregnation techniques.

Corrosion Samples

Mechanical sample preparation involves two main steps: grinding and polishing.

A. Grinding
The goal of grinding is to achieve a flat surface with minimal damage, so that any remaining imperfections can be removed quickly during polishing. Grinding is performed in two stages: coarse grinding and fine grinding.

• Coarse grinding ensures that all samples have a uniform surface by using coarse, fixed abrasive particles to rapidly remove material.
• Fine grinding refines the surface but may cause slight deformation, which will be corrected during polishing.

B. Polishing
Polishing is carried out to eliminate the damage left behind from grinding. It is typically divided into two methods: diamond polishing and oxide polishing.

• Diamond polishing uses diamond abrasives to produce the smoothest surface in the shortest time.
• Oxide polishing is used for particularly soft or tough samples, where diamond polishing may not be sufficient.

After polishing, the tested area becomes reflective. To clearly observe the tissue structure of the sample, the polished surface must first be etched.
