Multitasking machine handles gear cutting

In addition to turning and grinding bores, diameters and end faces, Stratos turning/grinding centers from United Grinding Technologies Inc. do gear-cutting. Reportedly, the dual grinding and turning capabilities of these machines reduce processing time 25 percent compared with conventional grinding and hardturning. X-axis travels are 1,050 to 1,750 mm, with Z-axis travels of 250 mm. Stratos internal grinding systems have arbors with 150-mm aluminum oxide or CBN wheels, and 36,000-rpm spindle drives are standard. External grinding systems feature interchangeable spindle and motor units and 3,000-rpm spindle drives. Turning systems feature manually activated block-type lathe tools rigidly mounted to machine-bed pedestals.grinding.com
