Custom clamping jaws, developed for a vertical machining environment. A Northfield 650 air chuck has been adapted to work with custom jaws.
The ‘pie’ shaped top jaws provide a full wrap clamping around the work piece. This project also includes a custom spring loaded locating pin assembly. Designed to orient the customer’s workpiece allowing fast and accurate change over.

Brief & Challenge:
Our customer manufactures delicate ceramic rings. They needed a way to carefully hold them on the outer diameter so they could grind the inner diameter. In order to protect the parts, they requested the chuck had no metal contact points.
Solution:
We produced a 6” Diaphragm Chuck with non-metallic top tooling in contact with the customer’s part. The top tooling, made from the most abrasion-resistant plastic available can be quickly changed, for new ones, should a future need arise.

Recently at Northfield we produced a custom internal grip collet chuck for balancing drive shafts.
The collet on this chuck is ground to grip the pitch diameter of splined C.V. joints of a driveshaft assembly.
The ‘cone’ has multiple stop pads for axial location. The chuck assembly is balanced prior to production using the tapped holes. The chuck repeats to less than 0.005mm total indicator reading (T.I.R.).

Northfield is the world’s premier manufacturer of ultra-precision balance chucks for prop shafts. Producing chucks that weigh less than half of our competitors and the only chuck supplier recommended by major balancing manufacturers.
Northfield chucks feature:
Our recent product introduction, the Northfield Pressure-Lok TM Chucking System is an air chucking system that works without the air tubes and hoses.
The Pressure-LokTM air chuck once charged with air pressure can hold pressure for up-to 3 weeks! Ideally implemented in machining operations that do not have access to a continuous supply of air.
The quick connect fitting is compatible with all Northfield chucks. The air pressure can be altered between 5 & 80 P.S.I. to adjust the grip force as required, improving the flexibility offered by spring clamping alone.

These two chucks are 7-inch diaphragm chucks. For multiple gear sizes, chucks can be provided with interchangeable cages and top jaws.
We attach a custom designed axial locator cage to a standard chuck. This contains a series of floating gage pins in a flexible mounting. Then, we load the gear over the pins into the chuck. The jaws clamp over the pins to center and grip the gear providing a “best fit” centerline of the pitch diameter.
Pitch line gear chucks can be provided in sizes from 3-inch to 12-inch diameter, sliding jaw or diaphragm models and can be applied to spur or helical gear applications.

When starting new project it’s common to discuss similar experiences related to the customers business and to introduce the product range. At Northfield Precision we have two main product areas.
Northfield has over 50 years of hands-on experience working across multiple industries on a global scale. At Northfield Precision we excel at automotive, aerospace, and medical applications.
We can adapt any of our chucks to custom and very specific situations, for example, high precision finishing work with pneumatic clamping pressure. All we need is your machine specification or a technical drawing. Drop us a line sales@northfield.com or call (516) 431 1112
Repeatability is one common question. Our standard Air Chucks offer .0001 T.I.R. repeatability, best in class. Combined with our world leading precision and accuracy, this is where Northfield really sets itself apart from the competition.
Firstly, it is always our goal to completely understand the customer and their requirements before getting to work. This ensures we deliver the best possible product.
I always begin the conversation by discussing the exact application.
Finally, our custom specialities are best at high precision finishing work, and we excel at providing solutions that require light clamping pressure. Our chucks allow the pressure to be fine-tuned by the end user and is possible because of our extensive experience delivering pneumatic solutions.
We are always on hand to discuss your project and answer any questions.
