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.

A Machine Retool Could Save You Time & Money

C & B has completed hundreds of retools in our 35+ year history on all types of grinding machines. A retool is a great way to utilize your existing capital to run a new line of parts. Have grinding machines in storage or machines that are running parts for an expiring program? You could use those machines to run parts for a new or existing program! Don’t have any machines to submit for retooling? Not a problem, C & B has a large inventory of used disc grinding machines that we can tool to run your parts. A retooled machine will save you thousands over buying new! A retool will also require less lead time than a new machine build. Compared to the cost of purchasing a new machine, retooling your existing machine could save you over 75%! During a retool advancements can be made to the load/unload automation to increase dependability. C & B can also complete upgrades to the grinder that will lessen machine wear over time and increase up time!

The above machine was retooled for the General Motors Bay City plant. This double disc grinding machine is setup to grind connecting rods. C & B replaced all part details with new to allow the machine to run a different program of connecting rods. Advancements were made to the load/unload automation during this retool to make the components more efficient and reliable. 


Contact us today and we can discuss if a retool is right for you!
