That will be very terrible news and feeling when client told you we can’t assembly the parts well, due to the out of tolerances. And we have analyzed the main reasons for them, the supplier doesn’t have the ability to design a good process to achieve it, or their managing system is not perfect to assure the quality stability.
We know the importance of precision tolerance and how to achieve and keep it. The below is a real case study.
Motor housing and covers used in automatic revolving door
very high geometric tolerance requirement to keep the motor operated precisely with long-lasting life.
·Finding a great idea with one-time finished all geometric dimensions
·Designing perfect machining fixtures
·Utilizing state of the art machining equipment.
Part name: Motor housing
Weight: 860 grams
Application: Automatic revolving door
Exported country: Switzerland
Problem:
Client had the problems on the precision tolerance and the over high cost to produce in Switzerland
Solution:
·Asked our experienced engineer to design a integrated machiningprocess, building 3d model.
·Developed a highly machining fixture and customized cutting tools.
·To validate our process, we made some prototypes with aluminum profile machined, then sending to client for finally verifying.
Benefit:
·Got the tight tolerances guaranteed
·Saving the overall cost of part
·Made a real validation before a big amount of tooling investment
