384 180° SF-RAZ TONGUE & GROOVE 2 Position hydraulic ring indexing chuck ■ 3 self centering and 3 compensating jaws ■ Large evacuation windows for easy chip flow ■ Fully automatic and controlled indexing ■ Hydraulic actuation Application/customer benefits • Machining of couplings in one set up • Indexing 180° in 2 seconds • 6-jaw clamping for perfect roundness of the coupling = ideal for premium threads • High-Low clamping (roughing-finishing) Technical features • Hydraulic, automatic ring indexing chuck • All functions controlled by proximity switches • Extremly accurate and rigid indexing mechanism • For external clamping only • Automatic central lubrication Standard equipment Ordering example Chuck with mounting bolts SF-RAZ 950-3+3 A 20 Accessories Hydraulic manifold including electric manifold, hose kit Picture 1 Clamping the coupling on the outside diameter with 6 jaws (3 self centering and 3 compensating jaws) and machining the thread on side 1. Picture 2 Indexing the chuck 180° with the coupling remaining clamped. Picture 3 After indexing 180°, machining the thread on side 2. Machining of a coupling in one set up: Picture 4 3 self centering jaws center and clamp the coupling. Picture 5 When the coupling is centered and clamped, 3 compensating jaws clamp the coupling additionally to distribute the total clamping force onto 6 jaws = less deformation of the coupling / perfect roundness of thread.
