Tapmatic Corporation has specialized in the development and production of self-reversing tapping attachments from its outset in 1952. These years of experience and close cooperation with their customers have resulted in the C.S.T. System, the fastest way to tap on any machine.

C.S.T., Constant Speed Tapping, evolved into its present form over the past several years as a result of its initial introduction at a new state-of-the-art automotive manufacturing facility and an experimental automotive plant in the U.S.A.

Tapmatic was inspired by the automotive industry’s manufacturing philosophy which demands predictability, avoids tool breakage and minimizes machine down time.

When synchronous feed tapping was introduced a few years back, the publicity made it sound as if there would no longer be a need for tapping heads or chucks. The controls and the machine would do it all.

However, the electrical engineers and computer specialists, who developed synchronous feed, designed their system around machine reversal and this required the machine to reduce RPM as the synchronized feed rate was slowing down near the end of the stroke.

Every machinist knows, reducing RPM in the middle of a cut is bad for tool life.

Synchronous Feed takes time, especially since it requires two machine reversals for each tapped hole. That’s not the way to increase production!

The present CST System has been built around the requirements of manufacturers who are demanding higher and higher speeds and machine tool builders who are building the machines to do it. 20,000 to 30,000 RPM spindles are not meant to reverse. So, even though we have the fastest tapping system available today, we’re adding new capabilities and we’ll be tapping even faster in the future.

In addition, CST heads take a big load off the machine. Power consumption comparisons prove Tapmatic CST taps up to four times faster than synchronous feed, using one fourth as much machine power. The components within the head now absorb the wear and tear that formerly occurred within the machine. The strain formerly taken by the machine is absorbed in an inexpensive easily replaced component within the tapping unit. This Renewable Drive element can be exchanged in less than 5 minutes. There’s virtually no machine down time due to tapping.

The high pressure internal coolant system handles up to 1,000 psi without seals.

The Interchangeable Chuck Spindle version provides quick change and accepts Intertap and steel collet chucks. The ER collet chucks are pre-setable.

CST is a modular system that allows Tapmatic to assemble a tool to meet a manufacturer’s specific requirements, whether they be hard-to-reach holes, misalignment problems, precise thread depth or - you tell us.

The CST program is continuing to expand. Recently added was a coolant compatible cutting fluid dispenser called the Automiser, that delivers a specialty fluid through to the tapping head itself and is activated when the tool changer inserts the head into the machine spindle. This affects both tap life and thread finish.

The Automiser is easy to install and dispenses the coolant compatible cutting fluid through the tapping head, automatically, while the head is in the machine spindle. Insertion or removal of the head automatically turns on or off the dispenser. There’s no extra programming or M functions required. Program the CST tapping head and you’ve programmed the dispenser as well.

Tapmatic is riding the wave of the future and can provide faster, more accurate and economical tapping on any machine. For more information contact your local distributor:
