Resin Bond Diamond Grinding Wheels

Applications & Functions

Our resin bond diamond grinding wheels (high-precision abrasive wheels with custom CNC-machined metal cores and synthetic diamond matrices) are engineered specifically for high-efficiency sharpening, finishing, and surface grinding of ultra-hard, brittle materials. Manufactured by molding synthetic diamond abrasive particles with thermo-setting resin matrix onto ultra-stable CNC-turned aluminum or steel hubs, these grinding wheels deliver excellent self-sharpening ability, minimal thermal damage, and exceptional surface finish.

They are extensively utilized across various precision toolmaking, industrial manufacturing, and material processing sectors:

• CNC Tool & Cutter Grinding: Essential for sharpening and manufacturing tungsten carbide end mills, reamers, drills, inserts, and woodworking cutters.

• Precision Machinery & Automotive Parts: Used for precision OD/ID cylindrical grinding, face grinding, and groove forming on hardened alloy components and ceramic seals.

• Advanced Ceramics & Semiconductor Materials: Ideal for planarizing, slicing, and edge-profiling silicon wafers, zirconia ceramics, quartz, and sapphire substrates.

• Glass, Gemstone & Optical Processing: Applied in high-precision edging, beveling, and surface polishing of optical lenses, technical glass, and hard synthetic stones.

Outstanding Product Features

• Superior Self-Sharpening & Elastic Bonding: The resin matrix continuously reveals sharp diamond grit during grinding, providing smooth cutting action with low heat generation and minimal workpiece burning.

• Precision CNC Aluminum/Steel Core: Base hubs are turned and milled with ultra-tight concentricity (+/-0.005 mm) on multi-axis CNC lathes, reducing operational vibration and extending tool life.

• High Removal Rate & Fine Surface Finish: Premium synthetic diamond grains ensure fast stock removal while achieving mirror-like surface roughness (Ra under 0.2 microns) on carbide and ceramic workpieces.

• Dynamic Balancing & Low Noise Operation: Every finished wheel undergoes rigorous dynamic balance calibration to prevent spindle chatter, spindle wear, and noise at high speeds (up to 35-80 m/s).

• Customizable Bond & Grit Configurations: Available in wide selections of diamond grit sizes (FEPA D46 to D126 / 80# to 3000#), diamond concentration levels (50% to 125%), and rim profiles (1A1, 1V1, 11V9, 12V9).
