The customer is machining wind energy ring gears made from 8620 using a Mazak Integrex 1550V-II with 800 PSI (55 bar) of water soluble coolant.
When the customer changed the size of the part, the 880 Drill could not achieve the extra depth required to complete the job. The new required depth of the hole was 14.4” (336 mm).
The GEN2 T-A met the customer’s goals.
