New 132EG Cross Slides Offer Added Strength, Easier Maintenance

CJWinter’s 132EG series cross slides have recently been updated to include several new features to improve serviceability, longevity and quality of the slides.

The top blocks are now smaller and position specific, making them more similar to the classic Davenport size for 1st and 2nd position.

Engineering Bulletin: How to Keep Attachments Running Efficiently

Protecting your assembly from moisture and debris is critical to avoid leaks and contamination.

Over CJWinter’s 60 years of experience in the industry, we’ve identified a number of ways to keep thread rolling attachments running efficiently. Let’s look at an airline assembly as an example.

Engineering Bulletin: Thread Gaging

All threaded fasteners, fittings and connectors must be measured using accurate gaging methods to ensure the highest quality.

Blank specifications vary on straight threads and tapered pipe threads. When rolling a straight thread, machine the part's blank diameter to the maximum pitch diameter - .002 inch. Roll the thread until the pitch diameter is within specification — between the pitch diameter's maximum and minimum — and adjust the blank diameter until the major diameter is within specification — between the major diameter's maximum and minimum.

Engineering Bulletin: Blank Design

An incorrectly sized blank diameter can result in thread rolling issues like tapered threads, slivers and flakes, and off-size threads.

Blank design, therefore, is an important consideration in the thread rolling process to ensure parts are manufactured to the highest quality.

Engineering Bulletin: Extra Tooth Height Form

CJWinter designs a special tooth form that allows more material to be rolled into the root of the roll and a sharper crest on the part.

For US and Metric threads, this delivers additional adjustability between the major and pitch diameter specifications.

Engineering Bulletin: Use Easy Metal Flow Tooth Form to Eliminate Flaking

Learn how CJWinter's Easy Metal Flow Tooth Form eliminates flakes during the thread rolling process

Different materials have different forming characteristics during the thread rolling process. High sulfur, for example, can create flakes and slivers, thereby hindering the thread finish during cold forming.

The solution: Easy Metal Flow Tooth forms — a special form that concentrates forces at the root of the thread form, which helps plow material more efficiently during the cold form process. Ultimately, the increased and concentrated force minimizes, and in most cases eliminates, flakes from being produced when rolling brass, high sulfur, and other materials prone to flaking.
