Wheel Bond
How the wheel holds the abrasives; affects finish, coolant, and minimum/maximum wheel speed.
| Bond name | Bond symbol | Bond description |
| Vitrified | V | Glass-based; made via vitrification of clays and feldspars |
| Resinoid | B | Resin-based; made from plants or petroleum distillates |
| Silicate | S | Silicate-based |
| Shellac | E | Shellac-based |
| Rubber | R | Made from natural rubber or synthetic rubber |
| Metal | M | Made from various alloys |
| Oxychloride | O | Made from an oxohalide |
| Plated | P | Made by Electro / Electroless bonding of metal to hold abrasive |
Grain Spacing
Spacing or structure, from 1 (densest) to 17 (least dense). Density is the ratio of bond and abrasive to air space. A less-dense wheel will cut freely, and has a large effect on surface finish. It is also able to take a deeper or wider cut with less coolant, as the chip clearance on the wheel is greater.
Wheel grade
From A (soft) to Z (hard), determines how tightly the bond holds the abrasive. A to H for softer structure, I to P for moderately hard structure and Q to Z for hard structure. Grade affects almost all considerations of grinding, such as wheel speed, coolant flow, maximum and minimum feed rates, and grinding depth.
