Seven Major Advantages of Thread Forming vs Thread Cutting Taps

3/13/2019

Forming taps displace metal — cutting taps remove it.

BALAX stands for “BALanced AXially,” which is an important feature for all of our Thredfloer Cold Forming Taps. Balax Thredfloers are ground using our proprietary thread grinders that have a differential lead compensation device that produces cold forming taps with their lead crests exactly on pitch.

Other forming taps have lead thread cold forming teeth that are not ground on pitch. These forming taps actually cold-work the thread twice:

To form the in-accurate lead thread and
To move it on pitch.

This creates an axial thrust on the tap which increases tapping torque and reduces tap life.

Balax Thredfloers form the thread exactly on pitch the first time with no axial thrust, hence the name “BALanced AXially”. All Thredfloers require less tapping torque and provide longer tap life than forming taps ground with conventional methods.

Forming taps and cutting taps produce threads that gage identically and are interchangeable, but the similarity stops there. The way they produce threads is completely different:

Chipless Tapping - Since the thread is formed and not cut, there are no chips to interfere with the tapping process or to cause chip-removal problems in blind holes.
Stronger Threads - The grain flow of formed threads follows the contour of the thread resulting in greater thread strength. This is especially true for materials that work-harden such as steel and stainless steel.
Better Thread Gaging - Forming taps rearrange the metal in the hole to create the thread. Because no metal is cut away, the possibility of producing oversized threads is greatly reduc
Stronger Tap - The absence of chips eliminates the need for flutes, resulting in a solid, stronger tap.
Longer Tap Life - Forming taps last 3 to 20 times longer than cutting taps because they have no cutting edge to dull.
More Efficient Production - Longer tap life, less tap breakage, and faster tapping speeds combine to reduce cycle time and machine downtime.
Ideal for Non-Lead Screw Tappers - The ability to form their own leads makes Thredfloer Taps especially well suited for CNC machines or other machines without lead screws

Precision Ground Taperlock Thread Gages made by Balax have some very unique design, enginering, and production properties that distinguish them from most other thread gage manufacturers. Even with all of these advantages they remain competitively priced!

Superior Metallurgy

Made from High Speed Tool Steel., the same material as used in tap manufacturing.
Heat treated to 63-65 Rockwell C , the same hardness as used in tap manufacturing.

Superior Accuracy

Threads are ground on proprietary Balax Thread grinders. This unique grinding process provides accurate thread profiles with less lead error than other gage grinding methods used today.

Similar to Balax Thredfloer Taps, Gages are ground on proprietary equipment to prevent lead error.

Extra Length Feature
Balax "go" gages in sizes 4-40 (M3 x .5) and larger are made with a relieved or undercut thread section.

This longer-than-standard length feature allows gaging to thread depths achieved with standard tap thread lengths.

Reversible gages are no longer required to check deep tapped holes

Miniature Gages
Available in sizes ranging from 000-120 to 00-90 or .90 UNM to 1.40 UNM.
The high quality materials and special grinding process used to manufacture Balax Miniature gages provide a consistency and accuracy never before available with miniature gages. They are held in special collect type holders.

Certificate of Inspection
All Balax Thread gages are furnished with actual fifth place (.00000) measurements of pitch diameter and major diameter to guarantee the accuracy of your gage to Class-X ̋tolerance levels.

Balax Certificage of Inspection Thread Gage

Titanium Nitrided
Titanium Nitrided thread gages are available for all stock sizes.

Special Gages
Balax can custom manufacture gages to your specifications.
