1. Core Advantages of Resin Bond Technology

Compared to metal and vitrified bonds, Uking’s resin diamond grinding wheels offer a softer, more flexible bond system with the following key benefits:

Superior Self-Sharpening: Abrasives shed automatically to expose fresh cutting edges, maintaining consistent sharpness
Low Grinding Temperature: Significantly reduces workpiece burn, cracking, and residual stress — ideal for heat-sensitive materials
Excellent Surface Finish: Achieves stable mirror-like finishes of Ra 0.1–0.4 μm
High Efficiency: Lower grinding forces and reduced vibration, suitable for both wet and dry grinding

2. Uking Proprietary Formulation Advantages

Premium imported resin matrix combined with high-strength diamond and specialized fillers
Precisely controlled porosity and bond hardness for balanced wear rate — long life without sacrificing cutting efficiency
Every wheel undergoes dynamic balancing and laser dimensional inspection to ensure zero vibration at high RPM

FAQ

Q: What is a resin-bond diamond grinding wheel and what materials is it used to grind?

A: A resin-bond diamond grinding wheel uses synthetic diamond abrasive grains held in a phenolic or polyimide resin matrix. The resin bond is softer and more elastic than vitrified or metal bonds, which means worn abrasive grains are released relatively quickly, continuously exposing fresh sharp diamond – a property described as the wheel being “free-cutting.” This self-sharpening characteristic makes resin-bond diamond wheels the standard choice for grinding cemented tungsten carbide (WC-Co) cutting tools, polycrystalline diamond (PCD) inserts and blanks, CBN inserts, and technical ceramics (alumina, silicon carbide, silicon nitride). The elastic bond also reduces grinding burn risk on heat-sensitive materials like PCD and thin carbide sections.

Q: What grit size should be selected for different grinding operations on carbide and PCD tools?

A: Grit size selection follows the standard coarse-to-fine sequence for material removal and surface finish:

80–120 grit – stock removal and reshaping of carbide blanks, initial grinding of sintered PCD blanks from round disc to insert geometry.

150–220 grit – intermediate grinding, geometry definition, clearance and rake angle grinding.

320–400 grit – fine grinding, edge honing preparation, achieving Ra 0.2–0.4 μm on carbide flanks.

600-1200 grit – polishing passes on PCD cutting faces to achieve Ra<0.05 μm for mirror-finish insert edges.

The diamond concentration in the wheel (low: 50, standard: 75, high: 100 concentration) is selected based on material: higher concentration for hard materials (PCD, ceramics); lower concentration for softer carbide grades and faster cutting.

Q: How should resin-bond diamond grinding wheels be dressed and maintained?

A: Resin-bond diamond wheels require dressing when the wheel surface glazes (hard-bond surface with embedded swarf visible), when grinding forces increase significantly, or after prolonged storage. Dressing method: use a silicon carbide dressing stick or a diamond dressing roll at low infeed (0.01–0.05 mm per pass) with adequate coolant flow. This removes the resin surface layer and exposes fresh diamond grains. Overaggressive dressing wastes wheel life; under-dressing leads to glazing, burn, and poor surface finish. Wheel speed: resin-bond diamond wheels are typically rated at 20–35 m/s peripheral speed; exceeding the rated speed risks wheel burst. Coolant: use water-soluble grinding fluid for carbide and PCD grinding; dry grinding resin-bond wheels on carbide is acceptable at fine grit but increases thermal risk.
