Holzmann GSM30E_R30 Electric Tapping Arm for Tapping up to M30

The Holzmann GSM30E_R30 Electric Tapping Arm is a powerful professional machine designed for fast and accurate internal thread tapping in metal components. With its high tapping capacity, 1200 W motor, articulated arm and touchscreen control, it provides an efficient solution for engineering workshops, industrial maintenance, metal fabrication and production applications.

The GSM30E_R30 offers a tapping capacity from M3 to M30 in steel and up to M36 in aluminium. This makes it suitable for both common metric threads and demanding applications requiring large-diameter taps.

Its articulated arm allows the tapping head to be moved easily between different working positions without constantly repositioning the workpiece, which is particularly useful when working with large, heavy components or parts requiring multiple tapped holes.

M3 to M30 Tapping Capacity in Steel

With a capacity ranging from M3 to M30 in steel, the Holzmann GSM30E_R30 covers an extensive range of tapping applications. When working with aluminium, the maximum tapping capacity increases to M36.

This wide working range makes the machine suitable for general engineering, industrial maintenance, metal fabrication, frame construction, component manufacturing and assemblies requiring internal metric threads.

The GSM30E_R30 is particularly suitable for workshops looking for a versatile electric tapping system capable of handling both standard thread sizes and considerably larger diameters.

Powerful 1200 W Motor with 230 V Supply

The Holzmann GSM30E_R30 is equipped with a powerful 1200 W S1 motor, providing the performance required for its substantial tapping capacity of up to M30 in steel.

The machine operates from a 230 V / 50 Hz power supply, allowing it to be installed in many workshops without requiring a 400 V three-phase electrical supply.

This combination of high tapping capacity and 230 V operation makes the GSM30E_R30 particularly attractive for professional workshops requiring powerful tapping performance with a single-phase electrical supply.

Adjustable Speed from 0 to 200 rpm

The GSM30E_R30 features an adjustable rotational speed from 0 to 200 rpm. This allows the speed to be adapted according to the tap diameter, workpiece material and tapping conditions.

The ability to operate at low speeds is particularly important when working with larger taps, where an appropriate rotational speed helps provide greater control during the tapping process.

Articulated Arm with up to 1100 mm Reach

The articulated arm of the Holzmann GSM30E_R30 provides a maximum reach of 1100 mm. This large working area makes it possible to reach different positions on the same workpiece without moving the component after each tapping operation.

The machine also provides up to 520 mm of height adjustment, allowing the working position to be adapted to different workpiece dimensions and configurations.

This freedom of movement is particularly valuable for workshops handling large or heavy components and for applications requiring several tapped holes across the same workpiece.

90° Tilting Tapping Head

The tapping head of the GSM30E_R30 can be tilted up to 90°. Combined with the articulated arm, this increases the versatility of the machine and allows the tapping position to be adapted to different working configurations.

The arm is also equipped with a handle to facilitate movement and accurate positioning of the tapping head over the required working point.

Touchscreen Control for Tapping Parameters

The Holzmann GSM30E_R30 features a convenient touchscreen control for setting the parameters required for the tapping operation, including thread size and tapping depth.

The touchscreen simplifies machine setup and allows the operating parameters to be adapted quickly to different tapping jobs.

This centralised control is particularly useful for repetitive operations where several threads need to be produced using identical settings.

Manual and Automatic Tapping Modes

The GSM30E_R30 provides manual and automatic operating modes to suit different tapping applications.

• Manual mode: forward and reverse operation can be controlled manually by the operator.
• Automatic mode: once the preset tapping depth has been reached, the machine automatically initiates the reverse movement.

The automatic mode is particularly useful for repetitive operations and blind-hole tapping, as the required tapping depth can be set before machining begins.

Quick-Change Tap Holders with Friction Safety Clutch

The Holzmann GSM30E_R30 is supplied with a selection of quick-change tap holders incorporating a friction safety clutch. This system helps limit excessive loads on the tap during operation.

The quick-change system also makes it easier to switch between different thread sizes, an important advantage in workshops where several tap diameters are used throughout the working day.

Air-Oil Cooling and Lubrication System

The GSM30E_R30 features an air-oil cooling and lubrication system designed to support metal tapping operations.

The system operates with a working pressure of 6 to 8 bar. Effective lubrication and cooling are particularly important during metal tapping as they help reduce friction and heat around the tap and workpiece.

Tap Holders Supplied with the Holzmann GSM30E_R30

The GSM30E_R30 is supplied with a comprehensive set of tap holders covering a wide range of metric thread sizes:

• DIN 371: M6, M8 and M10
• DIN 376: M12, M14, M16, M18, M20, M24, M27 and M30

This selection allows a large proportion of the machine's tapping capacity to be used from installation.
