Roscamat Electric Tapping Arm Machine - Dragon
We can consider the usage of the machine R-Dragon identical to the R-Tiger, but with the advantage of having much more working area, because of the length of the arms.
The machine consist of a radial supporting both articulated arms that can be adjusted by means of hte regulation handwheels to position them at the operator’s convenience
The multiposition head is a double swivel joint device allowing to lock and unlock both swivel pins to thus position the head and keep it blocked in order to thus operate in any space position.
Through the base by three M8 screws the machine can be fixed to a table or workbench. Such attachment can also be obtained by means of a simple clamp.

Quick-change toolholder
A wide of tapholders, all of them WITH or WOTHOUT clutch, apart from other quick holding fixture for different tools, such as drills, sinking tools, threading dies, socket wrenches, etc. are available. Tapholder with safety clutch so that it slips when it reaches the hole bottom. Type 1 Ø19 mm: capacity range M2-M16 (for modules 1050, 750, 550, 300 rpm); Type 2 Ø31 mm: capacity range M6-M30 (for modules 170, & 90 rpm) Tapholder without safety clutch for holding different tools with cylindrical shank and driving cube. Type 1 Ø19 mm: capacity range M2-M16 (for modules 1050, 750, 550, 300 rpm); Type 2 Ø31 mm: capacity range M6-M30 (for modules 170 & 90).
Modular System
The modular system provides for a new concept in the use of articulated tapping arm 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 M27 (M33) threads.
| Module | Max. Speed (rpm) | Max. Torque (Nm) | Coupling diameter | Max. Thread Aluminium Cast Irons | Max Thread Steel . |
| 90 | 90 | 150 | Ø 31 | M30 – 1 /1/8” | M27 - 1 “ |
| 170 | 170 | 79 | Ø 31 | M24 - 7/8” | M20 - ¾” |

Automatic tap lubrication (OPTIONAL)
AUTOMATIC TOOL LUBRICATION: The “automatic thread lubrication system” is attached to the lower part of the radial arm. If it is not preinstalled on the machine, it can be attached later. The lubrication time is counted in seconds and adjusted using the potentiometer on the upper part of the radial arm.
