| TBP-BM | ①1 pass machining * no extra operations required |
| Competitor’s product | ①Roughing – grooving operations ②Finishing – back turn operation |
The current process required 2 steps to complete the part feature.
NTK’s BM chipbreaker achieved shortened cycle time with a single-pass operation.
High quality finish on the OD and shoulder due to the chipbreaker design which evacuates chips away from the part.
