Holzmann GSM16E_R11 Electric Tapping Arm for M3 to M16 Tapping
The Holzmann GSM16E_R11 Electric Tapping Arm is designed for fast and accurate internal thread tapping in metal components. With its articulated arm, 600 W electric motor and touchscreen control, it provides an efficient solution for engineering workshops, maintenance departments, metal fabrication and production applications.
The GSM16E_R11 offers a tapping capacity from M3 to M16 in steel and up to M20 in aluminium. Its articulated arm allows the tapping head to be moved easily from one working position to another without constantly repositioning the workpiece.
This makes the machine particularly suitable for repetitive tapping operations, small production runs and large or heavy workpieces that are difficult to move.
M3 to M16 Tapping Capacity in Steel
The Holzmann GSM16E_R11 is designed for tapping threads from M3 to M16 in steel. When working with aluminium, its tapping capacity extends from M3 to M20.
This wide working range makes the electric tapping arm suitable for numerous applications in general engineering, component manufacturing, maintenance, metal fabrication and the production of assemblies requiring internal threads.
Articulated Arm for Excellent Freedom of Movement
One of the main advantages of the Holzmann GSM16E_R11 tapping arm is its excellent positioning flexibility. The articulated arm allows the tapping head to be moved easily over the workpiece to reach different tapping positions.
This configuration reduces the need to repeatedly move large or heavy workpieces and allows several holes on the same component to be tapped efficiently.
The arm provides a working range of up to 1030 mm, making it particularly practical for professional workshop applications.
0–90° Tilting Tapping Head
The tapping head of the GSM16E_R11 can be tilted from 0 to 90°. This feature increases the versatility of the machine and allows the tapping position to be adapted to different workpiece configurations.
Combined with the articulated arm, the tilting head makes the GSM16E_R11 suitable for a wide variety of tapping operations while maintaining excellent accessibility around the workpiece.
Touchscreen Control for Tapping Parameters
The Holzmann GSM16E_R11 features a convenient touchscreen control panel mounted directly on the arm. It allows the operator to configure the main parameters required for the tapping operation.
Settings include rotational speed, thread size, thread pitch and tapping depth, allowing the machine to be quickly configured for different applications.
The touchscreen provides convenient centralised control and makes it easier to adapt the machine when changing between different tapping operations.
Adjustable Speed from 0 to 312 rpm
The GSM16E_R11 provides an adjustable spindle speed from 0 to 312 rpm. This allows the speed to be adapted according to the tap diameter, workpiece material and tapping conditions.
Selecting an appropriate speed is important for producing clean threads and reducing unnecessary stress on the tap during machining.
Manual and Automatic Tapping Modes
The Holzmann electric tapping arm offers two operating modes to suit different applications and operator preferences.
- Manual mode: forward and reverse movement is controlled manually by the operator.
- Automatic mode: once the preset tapping depth is reached, the machine automatically initiates the return movement.
Forward and reverse rotation can also be controlled directly from the operating handle, making it easy to control both the tapping and tap withdrawal operations.
Quick-Change Tap Holders with Safety Clutch
The GSM16E_R11 features a quick-change tap holder system, allowing the tap holder to be changed quickly according to the required thread size.
The tap holders incorporate a friction safety clutch designed to limit excessive loads on the tap during operation.
This system is particularly useful for repetitive work and applications requiring frequent changes between different thread sizes.
Integrated Lubrication and Spray System
The Holzmann GSM16E_R11 is also equipped with a lubrication and spray system. Appropriate lubrication improves cutting conditions during tapping and helps reduce heat and friction between the tap and the workpiece.
This feature is particularly useful for regular workshop use and metal tapping applications.
600 W Motor with 230 V Single-Phase Power Supply
The Holzmann GSM16E_R11 is powered by a 600 W electric motor with a 230 V / 50 Hz single-phase power supply.
The single-phase supply makes the machine suitable for installation in many workshops without requiring a three-phase electrical supply.
Quick-Change Tap Holders Supplied with the GSM16E_R11
The electric tapping arm is supplied with a selection of quick-change tap holders covering the main metric thread sizes within its tapping capacity in steel.
- DIN 371: M3, M4, M5, M6, M8 and M10
- DIN 376: M12, M14 and M16
This comprehensive selection allows the machine to be used for many common tapping operations from installation.
