CASE STUDY

CNC SWISS MACHINING CASE STUDY: Automobile 11 Degree Connector Project 

The Challenge

Our CNC Swiss machining case study involved an automotive components company who was seeking a manufacturer to make a product that could be machined as one complete part and in one operation. At the time the part was manufactured in the following five operations:

  • Turning blank of part
  • Two secondary milling operations (milling flats and milling 11-degree diameter on the face of the part)
  • Two brazing operations of the two components before final assembly

 The Solution

After collaborating with our customer’s engineers, we devised a two-part operation process to develop and prototype one part while eliminating conventional secondary machining.  New process:

  • Developed a unique milling holder held at an 11 degree angle
  • Utilized a form tool to mill the diameter on the face of the part

The Results

The CNC Swiss machining case study savings not only reduced the time and cost per part, but it also allowed the customer to compound these savings over the course of the project by more than $300,000!

  • Cost- By eliminating secondary machining, the new cost was reduced by 39%.
  • Time – Original cycle time on the part was 8 minutes 23 seconds per piece. Together with the new changes and engineering support of our customer, the cycle time was reduced to 3 minutes 10 seconds per piece.
  • Savings –  The direct savings over the course of this project was $362,790.
