Electronic Vehicle Components – Ask me Anything Recording Part 2.

In this second part, CEO Paul de Feo presents a variety of recent projects. Demonstrating the accuracy of Northfield Workholding solutions. Including reverse and double diaphragm chucks.

 

Northfield Precision has been in business since the 1960s and constantly developing ever since.

This summer we introduced our very first ‘Ask me Anything’ webinar. Hosting an open discussion with customers and business partners to develop workholding knowledge together.

This presentation’s theme is on the hot trend of Electric Vehicle component manufacturing.

Due to operating with fewer parts and producing less vibration and noise than their combustion engine counterparts, EVs require parts that are created with higher tolerances concentricity.

This is where Northfield Precision can help.

Solution

The work holding solution is a Northfield model DPH-400, with custom Brass Work Holding Jaws. The top tooling consists of three parts.  

  1. Hardened and ground sub jaws  
  2. A separate center button stop 
  3. Precision ground brass inserts mounted to the sub jaws 

This setup ensures accuracy and repeatability whilst grinding the outer diameter to the required size.
