Industry Guide
UHD Ultrahard Tools Co., Ltd provides a professional comparison guide for diamond grinding disc selection, covering particle size, bonding method, workpiece material matching and applicable scenarios for high-strength grinding, including the application of UHD 100mm brazed diamond grinding 100.
Choosing the right diamond grinding disc directly determines the machining accuracy, work efficiency, and tool service life for industrial, stone and mechanical processing scenarios. As a professional manufacturer of ultrahard material tools, UHD Ultrahard Tools Co., Ltd has developed this systematic selection guide to help global industrial buyers identify the most suitable grinding solution according to their actual working conditions.
Core Parameters to Reference When Selecting Diamond Grinding Discs
A qualified diamond grinding disc selection process needs to cover three key dimensions, which are particle size matching, bonding type adaptation and workpiece material compatibility. Only by making a comprehensive judgment of these dimensions can you avoid tool wear, poor machining effect or unexpected cost increase caused by mismatching parameters.
1. Particle Size Selection Rules
- Coarse grit (30# - 60#): Suitable for fast rough grinding, large material removal scenarios, ideal for initial shaping processing of stone and hard cast iron.
- Medium grit (80# - 180#): Balances grinding efficiency and surface finish, fit for semi-finishing operation of most metal and non-metal hard materials.
- Fine grit (240# and above): Used for precision finishing and polishing, to obtain high-quality surface roughness requirements.
2. Bonding Type Comparison
The bonding technology is the core factor that fixes diamond abrasives to the substrate, which directly affects the tool's structural strength, heat resistance and service life:
| Bonding Type |
Core Features |
Typical Application |
| Resin Bond |
Low grinding noise, good finish, low heat resistance |
Precision polishing for low load operation |
| Metal Sintered Bond |
High wear resistance, long service life |
Continuous mass grinding work |
| Brazed Bond |
High holding strength for diamond, high exposure of abrasive grains, excellent heat dissipation |
High-strength heavy load grinding of hard and tough materials |
3. Workpiece Material Matching Guide
Different material hardness, brittleness and thermal conductivity determine the suitable diamond grinding disc performance level:
- Cast iron, carbon steel: Need grinding discs with good chip breaking performance and anti-clogging ability
- Stainless steel, hard alloy: Need high bonding strength, high temperature resistant grinding solution
- Stone, glass, ceramic: Need grinding discs that balance cutting efficiency and avoid edge chipping
