This is the genuine unit to work in any position in space therewith always maintaining the perpendicularity to the desired plane irrespective of the arm position. The machine consists of a radial arm supporting both articulated arms that can be regulated by means of the regulating valves. The multiposition head is a double swivel joint device allowing to lock and unlock both its swivel pins to thus position the head and keep it quite blocked in order to thus operate in any position in space. The head mechanism is formed by a cam system with an equaliser and disc springs applying a load of 1,000 Kg to two cone sets locking both pins. The radial arm incorporates a chain drive, which is activated or deactivated by means of a face-toothed coupling half according to the intended working position. The machine incorporates an air servicing unit (filter + regulator + lubricator) for the correct operation of the motor. The modular system consisting in a series of 7 quick-change modules (reducers) is provided for coupling to said motor. As a result of this 7 output speeds (90, 170, 300, 550, 750, 1050 and 2100 rpm) are available thus allowing to adapt the tap speed to every type of thread. The modular system admits the quick-change tap holders with or without safety clutch depending on the intended job (blind or through holes). Threading capacity from M3 up to M2 to M24 (M27).

The modular system provides for a new concept in the use of articulated armed threading machines. Driven from a single motor, seven different speed modules are available with their relevant power torques. The seven quick-change speed modules provide the speed and torque for each threading type, from M2 to M24 (M27) threads

A wide range of tapholders, all of them with clutch and without it, apart from other quick holding fixtures for different tools, such as drills, sinking tools, threading dies, socket wrenches, etc are available. · Toolholder with safety clutch: so that it slips when it reaches the hole bottom. Type-1 Ø19 capacity range M2-M16 (for modules 300,550,750, 1050) Type-2 Ø31 capacity range M14-M27 (for modules 90 and 170) · Toolholder with safety clutch: so that it slips when it reaches the hole bottom. Type-1 Ø19 capacity range M2-M16 (for modules 300,550,750, 1050) Type-2 Ø31 capacity range M14-M27 (for modules 90 and 170)

All ROSCAMAT units (400, 500 i 500RH) can be supplied with automatic tap lubrication system. The system is comprised of a regulating valve and a lubricant reservoir, and is actuated by the compressed-air system itself. When starting to tap the oil or liquid flow rate can be regulated for the purpose of lubricating the tap during the operation.
