Along the same lines as with the pneumatic models, the machine is made up of a pendular parallelogram being balanced by an air spring plus a radial arm. The assembly being made up of both members fixes the motor head and keeps it in a position being perpendicular to the working area. The electronically controlled motor is provided with a numerical control (NC) system.

The unit is apt to be operated in manual or automatic mode in such a way that it allows to configure an control by means of a six-key keyboard being arranged at the top of the motor such aspects as: - Right- and left-hand turning control - Thread type (Metric, Whitworth, etc.) - Depth control - Time of tool lubrication - Type of material, resistance - Tapping speed A set of 6 reducer modules are apt to be fitted to the motor output by means of a quick-change system and allow to adjust the tapping speed as a function of the metric pitch to mechanise.

Said modules incorporate as well a quick-change system being apt to receive the tap holder with or without safety clutch.

The ROSCAMAT 9001 NC C33 is supplied with an articulated head of easy handling which allows us to turn the motor in vertical or horizontal position (0º - 90º) and work in both positions

We can increase the working area in 100 mm in order to work on different height levels

A wide range of tapholders, all of them with or without 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 900, 500, 320) Type 2 Ø31 mm: capacity range M6-M30 (for modules 140 & 75) Type 3 Ø48 mm: capacity range M14-M42 (for module 40) Tapholder without safety clutch for holding different tools with cylindrical shank and driving cube. Type 1 Ø19 mm: capacity range M2-M16 (for modules 900, 500, 320) Type 2 Ø31 mm: capacity range M6-M30 (for modules 140 & 75) Type 3 Ø48 mm: capacity range M14-M42 (for module 40)

Inside the arm, the cutting oil reservoir is located and used to lubricate the tool during the tapping operation. Manual, we can choose, on the screen, the time (in seconds) during we want to lubricate the cutting tool or tap. In automatic system, the lubrication time of the tool is predetermined in the NC program according to the tap size. However, by means of the screen keys, we can vary the lubrication time percentage depending on the material, the tap condition, motor speed, etc.
