Machining of a non-standard piece: tooth grinding solution

Sometimes in mechanics, it may be necessary to produce a piece for which the hobbing tool necessary but it is not available. This can happen due to procurement times or technical uncertainties that lead the customer not to invest in dedicated tools.

As an example, let's consider the case where we are asked to machine a pinion with a 2.3322 module, which is non-standard.

Solution: Machining by grinding the tooth

To manage this type of problem, a valid solution is to obtain the part directly by grinding the tooth.

The set up phase of the piece on tooth grinding is very important and involves the preparation of the part for subsequent processing. During this phase you can see the first grinding teeth.

Final result: profile and helix obtained

The final result of machining by tooth grinding is very satisfactory. The involute gauge graph shows the helix and profile obtained, which are perfectly in line with the specifications required by the customer.

Have you ever considered to use grinding to machine non-standard parts?
