If everything were different tomorrow

Lehner Holzbau produces prefabricated houses with a batch size of one. For many years, the company has relied on WEINMANN machines — not least due to the flexibility.

In Bonndorf in the middle of the Black Forest, Lehner Holzbau produces around thirty custom-made wooden prefabricated houses per year over a workspace of just 1400 m². "The compact design was one of the reasons why we opted for the WBZ 160 from WEINMANN. When you have a workspace as small as ours, every square meter counts," explains Managing Director Gunter Lehner.

The WBZ 160 is a compact carpentry machine with a wide range of applications, from simple cutting to complex beam processing work, such as dovetail joints. The system adapts automatically to the work piece dimensions. The tool changer provides space for up to twelve tools. The machine's flexibility and modular expansion options gave Lehner even more reasons to make the purchase: "If architects were to design completely different wooden houses tomorrow, we would definitely be able to build them using the WBZ 160 and WMS 120."

At Lehner, the WMS 120 CNC-controlled multifunction bridge from WEINMANN is used to perform the sheathing operations of the timber frame walls. Also equipped with a twelve-position tool changer, the bridge fastens the sheathing (at Lehner, the sheathing materials used are OSB or gypsum plaster board panels), formats the element and makes all of the openings. The system is combined with two assembly tables that are also made by WEINMANN.

For both systems, data is entered via the powerTouch interface or directly via a CAD program. The same data record can be used for both machines. "The powerTouch interface is the standardized operating system of the HOMAG Group, which WEINMANN has been a part of since 1998," explains Alfred Schlegel, Sales Manager for Southern and Western Germany at WEINMANN. "It enables simple and standardized operation of all HOMAG Group systems."

Even though the system is logical and simple to control, all future machine operators receive training at the WEINMANN site and are accompanied by WEINMANN employees for the first week of production. According to Lehner, this is standard procedure for all supplied CNC-controlled systems. A comprehensive range of services is also standard at the HOMAG Group. Every system is delivered fully enabled for remote maintenance. "Over 8% of service incidents can be resolved immediately, without the need to send a service engineer to the site," explains Schlegel. An online connection between the ServiceCenter and the corresponding machine computer allows the problem to be found and rectified via "Tele-Service-Net". Program modifications, updates and any backup of machine data are also performed in the same way.

Since it was founded in 1985, WEINMANN has developed its product portfolio on a consistent basis. The company started life by providing panel nailing tables, but now offers a complete product range for timber work. When asked where he sees WEINMANN in the coming years, Schlegel gives a clear answer: "It is important to keep listening closely to our customers. They know exactly what they want, and we make it happen."
