CONSTANT SPEED TAPPING

NON REVERSING TOOLS CONSTANT SPEED TAPPING For High-Production CNC Tapping Without Machine Reversal. Constant Speed Tapping relies on the compact tapping head to provide tap reversal. The machine spindle runs in one direction at the exact programmed speed and reversal occurs within the tapping head instantaneously upon machine retraction. Avoiding the RPM fluctuations,common to machine reversal tapping ensures these benefits: Reduces Cycle Time. Increases Tap Life. Improves Thread Quality. Eliminates Reversal Related Machine Wear & Tear Reduces Energy Costs.

CST Provides Results Like This In Just 60 Seconds Even On A 15 Year Old Fadal VMC TAPMATIC Constant Speed Tapping Heads Produce More HPM Holes Per Minute And More HPT Holes Per Tap On Full Size Machining Centers Than Any Other Tapping Method. *For 7075 aluminum, tap manufacturers recommend 90-100 SFM for cutting taps and 130 SFM for forming taps. Maximum recommended speeds were used in our tests. How Fast Can You Tap A Hole Using CONSTANT SPEED TAPPING? A Here Is A Simple Calculation You Can Make To See How Fast You Could Be Tapping. Seconds Per Hole Calculation F 2 x Depth x 60 secmmin. Feed Rate Inch Taps Example Your Oob Metric Taps Example Your Oob Tap Size F 1/4-20 Tap Size F M6 x 1 Speed F 2500 RPM Speed F 2500 RPM Feed Rate F 2500 : by 20 = 125 inch/min Feed Rate F 2500 x 1 = 2500 mm/min Depth F.50 inch Depth F 12mm Seconds Per Hole F.R8 seconds Seconds Per Hole F.58 seconds Now calculate using your own specific applications and compare with your current tapping cycle time to see how much time you can save when you eliminate machine reversal.

VERY IMPORTANT NOTICE Regarding Ramp or Exact Stop: Please note that the G code for "Exact Stop" or "Ramp" should not be used with a Tapmatic selfreversing tapping attachment. Please be sure that these are not in effect when tapping because they will cause the tapping cycle time to be significantly slower and thread depth repeatability to be less accurate. Fadal Machines: Use G8 to cancel the Ramp for tapping. G9 will turn the Ramp on again if desired for other operations.

RDT, RDTIC & RCT Installation Tapmatic Can Supply Tools Ready To Fit Your Machine. RDT, RDTIC and RCT units take the burden of reversal away from the machine and therefore require a stop arm to activate their self-contained reversing mechanism. This arm must be positioned by the orientation collar to the exact location of the machine s stop block then locked in place and fixed positively with the locking screw provided. Tapmatic has stop arms to fit most popular machines. Just give us your machine make and model #. If we have not already supplied tools for your machine, we may need the information shown below. If Your Machine Already Has A Stop Block We Will Need The Dimensions Shown Below To Prepare Your Tool. If we do not already have a custom stop arm available just provide the following information and we ll make one for you. Installing an RDT, RDTIC or RCT on your machine is simple and Tapmatic experts are as near as your phone for any help you may require. Please contact our factory at 800 854-6019, FAX: 208/773-3021 and simply provide the dimensions requested. We will supply a tool modified to fit your machine. 28.

More Reasons To Consider A Self-Reversing Tapping Head Turn Any VMCMHMC Into A High Speed Tapping Center Your older machining centers probably can t match the rapid feed and traverse rates of a high speed tapping center but during the feed rate of the tapping cycle itself, Tapmatic s Constant Speed more than makes up for this by eliminating two machine reversals per tapped hole. Avoiding the RPM fluctuations common to machine reversal tapping also increases tap life substantially. But Savings On Taps And Tapping Time Are Only Part Of The Story... Which Is Faster At The Same RPMb 49.8 HPM* Sec. 59.8 HPM* Sec. Hi-Speed Tapping Center Tapmatic & Machining Center TEST: (10) 6mm Roll Form Holes, 9mm Deep, 2500 RPM, 7075 Aluminum Even when the tapping center s RPM was increased to 4000, it didn t produce more *Holes Per Minute (HPM) than Tapmatic at 2500. SEND FOR COPY OF THIS VIDEO. CST permits your machines to operate at cruising speed in one direction and still produce more holes per minute than a high speed tapping center at higher RPM. This increases machine spindle life. Machine down time is a significant shop expense. By eliminating wear caused by machine reversal at high RPM some customers have saved as much as \20,000.00 on spindle replacements and down time annually.
