FAQ
Q1.How does the sintering process work, and how does it affect the performance of diamond grinding wheels?
A1. Working principle: Diamond particles are fully mixed with metal powder, put into a mold, pressed into the corresponding shape under high pressure, and then sintered at high temperature in a bell furnace to form a diamond grinding wheel.
The sintering process is carried out at high temperature, which makes the grinding wheel have better thermal stability. 2) The hot pressing process makes the diamond particles closely bonded to the matrix, improving the strength and durability of the grinding wheel. 3) The sintering process is carried out under high pressure, and the diamond particles are evenly distributed in the cutter head, which improves the grinding accuracy of the grinding wheel.
Q2.In what environment is the double-row grinding wheel used, wet or dry?
A2.Both dry and wet grinding are acceptable. Dry grinding is easy to use and more convenient. Wet grinding can effectively reduce the dust of the product during work and reduce the heat generated during grinding, thus extending the service life of the grinding wheel.
Q3: What bond should I choose for hard vs. soft materials?
A: As a rule of thumb, choose a bond hardness opposite to your material hardness — a softer bond for hard aggregate concrete, a harder bond for softer stone or masonry.
Q4: Do you accept small trial orders before a bulk purchase?
A: Yes — free samples are available for testing on your specific materials.
Q5: Can you produce under our own brand?
A: Yes, OEM/ODM services are available, including custom branding, packaging, and bond formulation.
