TECHNICAL FAQ
Frequently Asked Questions
Common questions about metal bond synthetic diamond grades, particle sizes and industrial grinding applications.
1. What is metal bond synthetic diamond powder?
Metal bond synthetic diamond powder consists of industrial
diamond abrasive grains used in metal-bond grinding wheels,
segments and other abrasive tools. Selection depends on
crystal characteristics, particle size, bonding system
and the intended workpiece.
2. What are the differences between SND-G20, G30, G40 and G60?
The four grades have different toughness classifications.
SND-G20 is medium-low toughness, SND-G30 is medium
toughness, SND-G40 is medium-high toughness and
SND-G60 is high toughness. Each grade has
different application and toolmaking considerations.
3. Are SND-G grades equivalent to MBD4, MBD6, MBD8 and MBD10?
MBD4, MBD6, MBD8 and MBD10 are commercial
comparison references for the corresponding SND-G grades.
These descriptions do not guarantee identical
specifications or performance across manufacturers.
Comparative evaluation should consider crystal shape,
toughness, particle-size distribution and application testing.
4. What mesh sizes are available?
Mesh specifications should be confirmed for each grade.
SND-G30 is available in 80/100, 120/140, 200/230
and 325/400 mesh. Please provide the requested
grade and mesh size when contacting SinoDiam.
5. Is SND-G30 suitable for glass beveling and carbide grinding?
Yes. SND-G30 is positioned as a medium-toughness fine-size
diamond abrasive for glass beveling and carbide grinding.
The final abrasive selection depends on mesh size,
the metal-bond formulation, tool design and
required surface finish.
6. Which materials can be processed with metal bond diamond tools?
Metal-bond diamond abrasive tools may be evaluated for
selected glass, carbide, ceramics, stone and
non-ferrous or brittle non-metallic materials.
The appropriate grade depends on the material,
processing operation and tool construction.
7. Can SND-G diamond grades be used in different bonding systems?
The SND-G series is positioned primarily for
metal-bond abrasive applications.
Suitability for other bonding systems should be
assessed according to the individual grade,
tool formulation and manufacturing requirements.
8. How do I select the correct SND-G grade?
Start with the workpiece and processing operation.
Then review diamond toughness, crystal morphology,
mesh size, bonding system, desired grinding
efficiency and target surface finish.
Application trials may be necessary.
9. What information should I provide for a quotation?
Please provide the requested product grade, mesh size,
target material, grinding or processing operation,
metal-bond system, estimated quantity and destination
country. If the desired grade is unknown,
describe your existing tool and application requirements.
