Northfield will be raising its prices between 0-5% on January 1, 2023, which will help us keep up with labor costs and keep taking care of our employees. We hope that you will understand the need for this and if you have any questions, please contact us at the channels listed below.
Electronic Vehicle Components – Ask me Anything Recording Part 1.
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.
In the first video, CEO Paul de Feo introduces several recent projects demonstrating the high level of accuracy achievable with Northfield Precision’s workholding solutions. including double diaphragm and reverse diaphragm solutions.
to learn more about how workholding solutions can support EV component manufacturing that require high tolerances (.00005”) and high RPM (20,000rpm+), discuss emerging challenges and trends of EV component manufacturing, and answer any of your most pressing EV manufacturing questions.
During this and future events we will openly share our expertise and industry knowledge to help you solve your current work holding problems. Be that electric vehicle applications, working with fine tolerances and delicate parts or learning how to scale your production capacity.
The Pressure-Lok™ air chuck is charged with air by a special handle and holds air pressure for 3 weeks. Ideally implemented in machining operations that do not have access to a continuous air supply. The quick connect fitting is compatible with all Northfield chucks and the air pressure can be altered between 5 & 80 P.S.I..
Northfield is the world’s premier manufacturer of ultra-precision balance chucks for prop shafts. These chucks feature the highest accuracy, shortest hung mass, highest rpm, and fastest most accurate changeover in chucks that weigh less than half that of our competitors.
Working students continue to visit Northfield as part of our continued commitment to supporting the community. This June we attended a luncheon to celebrate the hard work and development of the students that have come to work at the Northfield offices over the past year.
I really enjoy the variety of tasks I’m given to work on and even having the opportunity of meeting Paul the CEO. I’m very grateful for the experience during the school year and I look forward to working at Northfield every Monday.”
David – Long Beach Student
The luncheon was to thank the sponsors who have invited students to visit their business’ each week during the school year. All the students and aides were in attendance to celebrate their achievements.
David did a great job taking charge of a variety of tasks. Including updating the saw log. We log when material is cut and then track it in the shop if we need to find it. A job very important to the whole team.
Additionally, David had the opportunity to assist our accounting manager Linda. Providing a great overview of the business and introduction to the working world.”
We are the world’s premier manufacturer of ultra-precision balance work holding, with chucks weighing less than half of the competition. We are the only supplier recommended by major balance manufacturers.
Our mission, is to provide manufacturing companies with the most accurate work holding solutions in the world.
Northfield Balancing Chucks Feature:
Shortest hung mass
Fastest & most accurate change over
When parts rotate without calibration, uneven pressure can occur and cause errors with the end-product. Firstly, within a high precision environment the smallest difference can have a huge impact on the final product. Therefore, when fine tolerances are exceeded the result can be expensive and time-consuming repairs.
With ever increasing speeds used on rotating machinery, balancing is increasingly necessary. The trademark accuracy and repeatability of Northfield chucks allow customers to take their designs to the next level.
Recently we have been producing internal grip collet chucks for balancing drive shafts. They are capable of repeating to less than 0.005mm total indicator reading.
To achieve this, the collet is ground to grip the pitch diameter of splined C.V. joints of a driveshaft assembly. Secondly, the “cone” has multiple stop pads for axial location and finally, tapped holes are used to balance the chuck assembly prior to production.
8000 RPM Double Diaphragm Chuck
This customer required a chuck for their balancing machines to hold drive shafts by their slip-yokes.
Normal balancing operations are performed at approximately 900 rpm. High-performance vehicles like Stock and Formula 1 cars hit 200 mph with their drive-shafts rotating at 10,000 to 12,000 rpm. Therefore, this case required accurate holding at road conditions, 8000 rpm.
The Northfield solution consists of two separate custom diaphragm chucks built together. There are two separate sets of jaws, one mounted in front of the other. This accommodates the long, thin shape of the part. With one set of jaws gripping the front of the piece and the other gripping the rear.
The result is accuracy of 1/10,000″ T.I.R. and repeatability to 50 millionths with extreme rigidity.
This custom project used an 8” diaphragm chuck with custom top tooling for balancing aluminium turbine impellers.
The first, locates the workpiece using strategically positioned carbide pins between the blades and custom jaws clamping outside of blades.
The second, operation locates the impeller on the finished surface using a continuous ring locator. Custom jaws clamp the outside diameter of the workpiece. This allows the customer to finish balance the impeller blades
In summary, we offer both stock and custom solutions.
Northfield’s long-standing relationships in the balancing industry speaks volumes about the products and service offered. Get in touch today to discuss your latest product with the engineering team.
