Internally Gripping - Automotive Drilling

Custom automotive drilling work holding A drilling solution custom designed for the automotive industry. Based on hydraulically actuated, internal grip collet chucks.

Eight of these chucks mount on a pallet in a vertical machining centre, gripping automotive parts for drilling. The chucks are 76mm in diameter but deliver up to 544 kg. of draw force.

Plastic Tooling - Ceramic Grinding

Brief & Challenge:

Our customer manufactures delicate ceramic rings. They need a way to carefully hold them on the outer diameter so they can grind the inner diameter. To protect the parts, they requested no metal contact points.

Custom_Ceramic_Grinding_Chuck

Solution:

We produced a 6” Diaphragm Chuck with non-metallic top tooling in contact with the customer’s part. The top tooling is made from the most abrasion-resistant plastic available and these items are easily replaceable 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.

The collet on this chuck grips the pitch diameter of splined C.V. joints of a driveshaft assembly.

  • The ‘cone’ has multiple stop pads for axial location.
  • Tapped holes balance the chuck assembly prior to production.
  • 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, with chucks that weigh less than half of our competitors. We are also the only chuck supplier recommended by major balance manufacturers.

Custom Parts, Custom Colors

No, we’re not making a fashion statement for chucks here!

At Northfield, we affectionately refer to the aluminium anodized chuck as “BIG RED”. Creed Monarch use “BIG RED” to manufacture close tolerance parts for Robert Bosch Power Tools.

We designed “BIG RED” to accommodate the unusual shape of the ‘Wobble Plate’ part of the drive mechanism in a Bosch reciprocating saw. Improving accuracy and dramatically reducing change over time.

Model Big Red Custom Chuck
Northfield custom work holding, model ‘big red’

The “Wobble Plate” is made from 52100 tool steel and heat-treated to 58/63 Rockwell. Spinning at 3,500 rpm for hard turning the “Wobble Plate” internal diameter, creates the outer race of a bearing set.

“BIG RED” is a example of our custom work holding at Northfield beyond the chuck.

  • The spring-loaded plunger and locator ensure accurate locating of the “Wobble Plate” to four specific reference points.
  • When hand mounted on the face of a fixture, the unique design provide repeatability of 0.002 inches.
  • The fixture allows automatic operation after the initial loading.

“BIG RED” solved previous holding problems and saves a tremendous amount of production time.

Custom Automotive Diaphragm Chuck - Plastic Top Tooling

Northfield 3-jaw, 5” Diaphragm Chuck (DPH-500) with custom plastic top tooling
Northfield 3-jaw, 5” Diaphragm Chuck (DPH-500) with custom plastic top tooling

Customer Brief

Our customer is a heavy duty fuel pump and injector systems manufacturer. They requested a method to accurately grip their small (.098” OD) fuel injector plungers without marking them.

Challenge

Chuck close up, with part and custom stop.

The tip of their part must rest in a carbide seat, ground central to the chuck. This requires the special part stop.

Northfield Solution

Northfield 3-jaw, 5” Diaphragm Chuck (DPH-500) with custom plastic top tooling, disassembled view with part.

The jaws are made from a special, highly abrasion-resistant, engineered plastic. Designed to withstand repeated clamping with minimum wear. The bore diameter gripping the part yields an accuracy and repeatability of more than 50millionths” TIR total runout to the chuck’s center line.
