Introducing the new Power-Pin from Holz-Her. Launched at LIGNA 2023, this state-of-the-art drilling and dowel insertion machine is the perfect complement to nesting. With a horizontal drilling aggregate and a dowel insertion unit as standard, it eliminates the need for manual dowel insertion after CNC machining – presenting huge cost and time-saving benefits. Here’s how …
Suitable for use with workpieces from 60-2600mm in length, widths of 150mm for both horizontal and vertical machining and thickness of 12-60mm, the Power-Pin offers adaptable workpiece sizing.
Designed to incorporate all aggregates and storage tanks in the machine, the Power-Pin has a footprint of just 4 sq m and an overall height of just 1755mm (2095mm with the machine lid open).
The space on the lid has also been cleverly designed to offer storage space for workpieces and, depending on material flow, the Power-Pin can stand freely in a room or be placed against the wall.
The Power-Pin can drive in both pre-coated dowels and standard wooden dowels measuring 30, 35 and 40mm in length. For standard wooden dowels, glue is injected into the holes prior to insertion. With the optional second-step conveyor, the change from 6 to 8mm dowels is done in minutes.
Holz-Her’s Campus NC-HOPS software comes as standard on every Power-Pin. With simple operation at the forefront of its design, the software allows the user to programme individual components and adapt them quickly using simple macros.
Its EasySnaps parametrically programmable feature also guarantees the utmost precision, whilst the complete machining operation is displayed in a 3D format on a 21.5” touchscreen display for ease of use. A barcode scanner is also part of the software’s optimisation options.
The large-area support table enables multi-area loading of up to four components at one time. The intuitive clamping concept – which automatically adjusts depending on the material being processed – ensures that longer components up to 2600mm can be loaded and off-loaded quickly and safely. It also makes for simple operation when running large batch and recurring component sizes.
For short machining cycles, the dowelling unit can be variably off-set in 32mm increments up to 192mm, with the software automatically calculating whether simultaneous dowelling and drilling is possible. Depending on the number of holes and dowels, this can result in a 20% reduction in time.

For simple machining on the Power-Pin Dynamic, automatic program selection measures the width of the workpiece via a light barrier. When a pre-programmed workpiece width is detected, the appropriate program is automatically loaded. Additional VISE LED position indicators also simplify operation further. On the Classic, the drilling depths and height can be set manually with two pre-defined drilling depths.
Energy saving credentials
Eco Mode offers a time-controlled shutdown to save energy and reduce running costs.
The three-fold drilling unit allows for a variable speed from 2750-4000rpm and individually pre-settable drilling spindles in a 32mm grid – ideal for carcass construction.
“The new Power-Pin offers vast time savings as the horizontal drilling and dowelling can be done by the nesting CNC operator whilst the next sheet is being nested,” explains Paul Nightingale, national sales manager, Holz-Her UK.
“Thanks to the machine’s low machine height, the operator can easily oversee the nesting process whilst drilling and dowelling in masked time – essentially completing this step without adding any time whatsoever to production.”
