A cool break: General Industry Coverage

Aluminum is relatively easy to machine, especially when compared to heat-resistant superalloys and titanium, but as the silicon content increases or if the material is inherently gummy, controlling chips and economically cutting aluminum can be a challenge. To meet that challenge, toolmaker Lach Diamant, Hanau, Germany, combined its »Cool Injection« coolant-delivery system with the »Plus« chipbreaker to introduce »Cool Injection-Plus« PCD monoblock milling cutters.

According to the company, the combination cutter maximizes tool life, imparts mirror surface finishes, reduces cycle times up to 50 percent and provides high machining parameters, with a feed rate up to 40.000 mm/min. (1.575 ipm) and a cutting depth up to 8mm (0.315 “) at the maximum cutting speed.
