Angular Heads
Tradition in Perfection. For more than 50 years the name ROMAI has stood for the highest precision and process reliability in machining. The next generation begins today. We have succeeded to further improve the performance of our angular heads. More torque for the same size and at consistent acquisition prices. Both for standard and special functions. Just what you are used to from ROMAI.

RATIONALIZATION Angular Heads by ROMAI Minimizing the number of tool clampings Reducing the machining time Simplifying elaborate machining processes Exact reproduction of production steps Enhancing process reliability Reduction of machine downtime periods Machining of otherwise inaccessible parts of the work piece (internal machining) Cutting costs through complete processing Established Rotational Mechanics 4
NXT GENERATION The next Generation. Spiraltoothed bevel gear box with new tooth geometry and surface treatments 3050 % more torque For all machines For all tool systems Drilling, reaming, countersinking, threading, milling, and grinding Roughing and finishing up to 6,000 Nm With torque support (DMST), 3 or 4point support, mechanic/hydraulic clamping or flanged Internal and/or external coolant supply with pressures of up to 70 bar (useoriented of up to 140 bar, more on request) Transmissions and reductions of up to 40,000 rpm individually realizable 5
VERSIONS Form S Angular Head For machining tasks without geometric constraints. Internal coolant optional. ( 16) Form S2 Angular Head with bilateral output For machining tasks in the opposite direction or with different machining tools. Internal coolant optional. ( 17) Form W Angular Head with offset output For machining tasks with geometric constraints. Setback output to maximize the usable tool length. Internal coolant standard, can be omitted optionally. ( 18) Form G Angular Head with offset output (slim shape for special application) For special machining tasks with strong geometric constraints. Offset output to maximize the usable tool length. Internal coolant optional. ( 19) a Form F Angular Head with fixed angle (for special application) For special machining tasks in fixed angular position. Internal coolant standard, can be omitted optionally. ( 20) Form D Angular Head 0 with fine adjustment For machining tasks in changing, angular position. Because of the variable adjustment, any angle between 0 (process reliable) can be set. Up to optional. Internal coolant standard, can be omitted optionally. ( 22) 6
STRUCTURE Locking disc Connecting plate Driving shank (machine spindle) Torque support (DMST) Locking bush Rotation (360 ) Housing Output (tool holding system) Locking disc / locking bush Exact locking of the angular head for the automatic tool change. Exact fitting into the magazine and therefore process reliability is guaranteed. Driving shank Fitting of the angular head in the machine. All machine interfaces can be realized, e.g. HSK, SK, Capto, MASBT, CAT, and many more (see page 10). Connecting plate Support of the angular head against tilting during machining. Rotation (360 ) All ROMAI standard angular heads can be manually turned around 360. Fixation is with clamp screws. Hirth coupling is optional. Torque support (DMST) Locates the angular head at the machine spindle and secures it against tilting caused by machining forces. Because of the variety and the differences in machine tools, the torque support is usually implemented machinespecific, and we adapt it to the individual machine type. Output (tool holding system) Clamping of the cutting tool for machining. All tool holding systems can be realized, e.g. collets, WFB, HSK, SK, CAT, and many more (see page 12).
