Plastic Tooling - Ceramic Grinding

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.

Internal Spline C.V. Chucks

Recently at Northfield we produced a custom internal grip collet chuck for balancing drive shafts.

Balancing Splined C.V. Joints

 

 

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 Pressure-LokTM Chucking System

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.

Pitch-line Gear Chucks

Introducing the series of pneumatic actuated pitch-line gear chucks.

 

Helical Gear Chuck

Spur Gear Chuck
Spur Gear Chuck

How can we help you?

These two chucks are 7-inch diaphragm chucks. For multiple gear sizes, chucks can be provided with interchangeable cages and top jaws.

How do we do it?

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.

5 Minutes with Charles Florio Northfield Sales & Darryl Celli Senior Applications Engineer

How can we help?

Charles Florio, part of the US based Northfield sales team, and Darryl Celli, one of Northfields Senior application engineers, share their insights about how Northfield can help solve your work holding needs.

 

Thank you for taking the time. You are the first port of call for Northfield customers, tell us about the most common questions?

Charles…

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.

  1. Our standard high precision range of: Air, Diaphragm and Collet chucks. These are always available, in a range of sizes, for immediate order. Just give us a call. (516) 431 1112
  2. Custom applications and unique products are our second speciality Check out our custom projects for some ideas.

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.

 

Darryl…

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

 

Why should Northfield Precision be your preferred work holding provider?

Darryl…

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.

 

Charles…

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.

  • “What is the part material (metal, ceramic or glass).”
  • “Will the chuck be used in a turning or grinding environment?”
  • “What type of machine will the chuck be used on?”

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.
