C & B Introduces Our New Model Clamp Bore Grinding Machine

We are in the process of building our new single spindle model of our clamp bore grinding machine. A single spindle clamp bore is ideal for grinding parts that have tight tolerances, require bore-to-face perpendicularity, unequal stock removal and for plants with limited floor space! C & B Clamp Bore machines are available with tooling changeover options that allow you to perform part changeovers quickly and easily. The in-process gauging unit is available with a quick-change, error-proof adjustment as well. The cup grinding wheel arbor has the option to be pre-mounted to allow for a quick change with no tools required.

Part tolerances for the parts that will be ran on these machines:


± 0.03 mm


0.025 mm


0.050 mm


0.050 mm


0.5 Ra

Typically, these gears would be double disc ground. The bore-to-face perpendicularity cannot be altered by the double disc grind process, it holds the tolerance from the previous operation. With clamp bore grinding bore-to-face requirements can be met.

Close up of clamp bore tooling

The C & B single spindle clamp bore model # CBV4-1F-1S, has a robot load the part unto the tooling chuck, the 4-inch cup wheel comes down and grinds one side of the part based on the reading being picked up by the in-process gauge. The cup wheel retracts, the part is flipped over and then the wheel in-feeds to grind to size based on the in-process gauge reading. Once the part is finished the robot picks it up and places a new part on the chuck. The cycle time for one finished part is estimated to be 30 seconds.
