Success at Davan Manufacturing!

Davan Manufacturing in Pennsylvania is a new user of the Advent thread milling solution.  Mark Vanistendael of B/G Industrial Supply (Irwin, PA) Writes,  "We replaced a Seco-Carboly shell driven thread mill (p/n  R396-19-0228-4003-6A  insert grade F30M) with the Advent shell type thread mill (p/n  SM25TA-F8 insert grade Z TIALN) as we were having great difficulty with Seco inserts moving in the pocket. We found the short insert screws were backing off and allowing the insert to move freely with disastrous and costly results. The application has less than ideal rigidity and allows undesirable vibration in the work piece. Another issue we had with Seco was insert inventory was not stocked in the USA. We searched for a suitable tool and found insert inventory to be a problem with all the tool suppliers. B/G Industrial Supply had offered Advent as an alternative solution. We found the application support to be top notch and we were pleased the product was made and stocked in the USA. The tool quality is also top notch and Advent's help in programming the tool path was invaluable. We only hope to get your next generation software in our hands as the control over the tool path will be unsurpassed.

The following parameters were used.

4340HT Rc34-38 sand castings for underground coal mining application.Cutting 3 external studs per part to M30X2MMX40MM Length studs on a 50 Taper CNC HMC  with a custom made tomestone fixture to run 6 parts per pallet for a 1500 pc run.

Seco:     585rpm @ F25.3 ipm in one full depth pass to size in dia. Vs.

Advent:1000rpm @ F34.2 ipm in one rough pass to depth with stock on dia and one finish pass to size at full depth.

Although the cycle time is longer with the new tool, the old tool simply would not work when this job was moved for a vise operation in  a VMC to the HMC in a fixture and the tool life is averaging about the same for either tool at about 360 studs per edge."
