Are you looking for more from your tooling?
After facing problems with chatter and chipping inserts, our customer, who machines fueling machine head rotors from ASTM A276 - 304L in the nuclear power industry, sought a better solution to their machining process.
The customer turned to Allied for help finding a new solution. Once the causes of insert failure and chatter were identified, our experienced team was able to create the best assembly suitable for the application. Using Wohlhaupter’s analog balanced fine boring head paired with the NOVITECH™ vibration damper module, they were able to eliminate the issues our customers were facing.
With the previous tooling, the customer achieved only 12 minutes of tool life, but with Allied’s Wohlhaupter assembly, they achieved more than 4 times the life for 65 minutes!
Allied’s Wohlhaupter assembly improved the machining process by making it more consistent and saved the customer money by reducing cost per hole. If you are looking to save time and money, give us a call, and we will help you find the right solution.
