FAQ
Q: What is the difference between vitrified-bond and resin-bond diamond grinding wheels?
A: Vitrified-bond diamond wheels use a glass-ceramic (vitrified) matrix to hold diamond abrasive grains. The rigid, porous bond structure provides several advantages over resin bond:
(1) Profile retention – the hard vitrified bond holds wheel geometry precisely under grinding pressure, enabling complex form grinding of carbide profiles and PCD insert shapes with dimensional repeatability ±0.001 mm.
(2) Higher porosity – the open pore structure provides superior chip clearance and coolant penetration, reducing grinding burn risk on sensitive materials.
(3) Dressability – vitrified wheels can be dressed with high precision using diamond dressing tools, restoring profile accuracy after wear.
The primary limitation versus resin bond is brittleness: vitrified wheels require more careful handling and are not suitable for applications with significant vibration or workpiece interruptions.
Q: What applications require vitrified diamond wheels rather than resin-bond wheels?
A: Vitrified diamond wheels are the preferred choice for:
(1) CNC profile grinding of complex PCD insert geometries – the rigid bond maintains form accuracy through long grinding cycles on 5-axis CNC tool grinders.
(2) Flute grinding of carbide end mills and drills – profile must be held to ±0.005 mm across the wheel life.
(3) Centerless grinding of carbide rod and tungsten carbide balls – the wheel must maintain a precise cylindrical profile.
(4) Crankshaft and camshaft grinding with CBN wheels – vitrified CBN (not diamond) is the standard for ferrous precision grinding.
(5) High-speed grinding (Vs=45-80 m/s) – vitrified bond is structurally capable of high peripheral speeds that resin bond cannot safely achieve.
Q: How are vitrified diamond grinding wheels dressed and how often is redressing required?
A: Vitrified diamond wheels are dressed using a rotary diamond dressing disc, single-point diamond dresser, or CNC dressing unit. For profile grinding on tool grinders, dressing is typically performed by the CNC machine at set intervals (e.g., every 20–50 parts, or when dimensional feedback shows form drift beyond tolerance). Dressing infeed per pass: 0.002–0.010 mm; dress speed ratio (Uds = dresser speed / wheel speed): 0.4–0.8 for sharp, open wheel surface; 0.2–0.4 for smoother finish. Frequency of dressing depends on material ground, depth of cut, and required tolerance. Unlike resin-bond wheels, vitrified wheels can be reprofiled by dressing to a completely new form if the application changes, making the wheel body a longer-term capital asset.
