Question 1

How should diamond lapping film be used?

Accepted Answer

To use diamond lapping film, peel a strip from the sheet and adhere it to the platen, ensuring it is centered. Use an edge-trailing stroke (up and away) with the lapping film, unlike diamond stones.

Question 2

What materials are ideal for diamond lapping?

Accepted Answer

Boron carbide is an ideal abrasive for diamond lapping, particularly for hard materials like tungsten carbide and tempered steel. Its aggressive cutting and high stock removal capabilities make it suitable for lapping the hardest materials, including tungsten carbide and titanium carbide.

Question 3

What is the process of diamond lapping?

Accepted Answer

Diamond lapping (https://www.diamondlappingfilm.com/lapping-film-disc)is a material removal method using fixed diamond abrasive (https://www.hansinc.com/)particles which produce long chips of the component material. The process of making chips with a sharp abrasive (https://www.hansinc.com/)grain produces the lowest amount of deformation in the component while giving the highest removal rate.

Question 6

What is diamond lapping fluid made of?

Accepted Answer

Diamond lapping fluid,(https://www.diamondlappingfilm.com/diamond-slurry) also known as water-soluble coolant, is commonly used in conjunction with diamond lapping films and other precision polishing tools. This type of coolant enhances the water with additional features to improve the lapping process. Here are the details, benefits, and some challenges associated with using Diamond lapping fluid:(https://www.diamondlappingfilm.com/diamond-slurry)
Benefits of Diamond Fapping Fluid(https://www.diamondlappingfilm.com/diamond-slurry)
1. Enhanced Cooling: Diamond lapping fluid (https://www.diamondlappingfilm.com/diamond-slurry)improves the cooling efficiency of water, helping to dissipate heat generated during the lapping process. This prevents overheating and potential damage to both the workpiece and the lapping film.
2. Lubrication: The fluid provides better lubrication than plain water, reducing friction between the abrasive film and the workpiece. This helps in achieving a smoother finish and extending the life of the lapping film.
3. Particle Suspension: It helps to suspend the abrasive particles and swarf (material removed from the workpiece) in the coolant, preventing clogging of the lapping film and ensuring a consistent cutting action.
4. Corrosion Protection: Many Diamond lapping fluids(https://www.diamondlappingfilm.com/diamond-slurry) contain additives that protect both the workpiece and the lapping equipment from corrosion, especially when working with metals.
Challenges of Using Diamond Fapping Fluid(https://www.diamondlappingfilm.com/diamond-slurry)
1. Concentration Management: As the water component of the coolant evaporates, the concentration of the fluid increases. This can lead to changes in the performance of the fluid, potentially causing issues with consistency and effectiveness. Regular monitoring and adjustment are necessary to maintain the correct concentration.
2. Frequent Testing: To ensure optimal performance, the concentration of the lapping fluid needs to be tested frequently. This adds an extra maintenance step and requires the use of appropriate testing equipment and methods.
3. Potential Residue: If not managed properly, the evaporation of water can leave behind residues that may affect the lapping process or the final finish of the workpiece.
4. Storage and Handling: Proper storage and handling are required to maintain the efficacy of the Diamond lapping fluid.(https://www.diamondlappingfilm.com/diamond-slurry) Contamination or improper storage conditions can degrade the fluid’s performance.
Best Practices for Using Diamond Fapping Fluid(https://www.diamondlappingfilm.com/diamond-slurry)
1. Regular Monitoring: Implement a regular schedule for testing the concentration of the lapping fluid and adjusting it as necessary. Use a refractometer or other suitable devices to measure concentration accurately.
2. Top-Up with Water: Regularly top up the fluid with water to compensate for evaporation and maintain the appropriate concentration.
3. Clean Work Environment: Ensure that the work environment and all equipment used are kept clean to prevent contamination of the lapping fluid.
4. Proper Storage: Store the fluid in a cool, dry place and keep containers sealed when not in use to prevent contamination and evaporation.
By following these best practices, the advantages of using Diamond lapping fluid (https://www.diamondlappingfilm.com/diamond-slurry)can be maximized while mitigating the potential challenges associated with its use.

Question 7

What is the main goal of the lapping process?

Accepted Answer

The main goal of the lapping process is to produce parts with a uniformly smooth and flat surface. This is achieved by removing material from the high points of the part's surface through contact with a flat lap plate.

Question 8

How much material is typically removed during the lapping process?

Accepted Answer

The lapping process is gentler than honing and removes significantly less surface material. Typically, lapping removes only 0.0005” to 0.005” (0.0127 mm to 0.127 mm) of material. Therefore, the workpiece should be as close to the final size as possible before lapping, often achieved through double-disk grinding.

Question 9

What is the proper method for cleaning a diamond lapping plate?

Accepted Answer

To clean a diamond lapping plate, evenly apply Bar Keepers Friend using a nylon brush. Gently scrub the plate for one to two minutes, then rinse with warm water while continuing to scrub. Ensure thorough rinsing to remove all residues.
