PORTLAND, Ore. — The 8th annual International Mass Timber Conference will launch in about a month, and SCM and Randek will be joining the innovators, disruptors and forward-thinkers who want to promote a greater use of cross-laminated timber and other mass timber products in the sector.

SCM, a global leader in advanced machinery for the entire woodworking and timber construction industries, and Randek, developers of high-performance systems for prefabricated houses, will be among more than 130 exhibitors participating in the event with a common mission: to explore and encourage the advantages of green building made possible with innovative, efficient and sustainable production processes and materials.

SCM and Randek will provide their contribution in terms of know-how and innovation, by illustrating cutting-edge solutions, designed following the positive trend of wooden multi-story buildings, both in North America and Europe. 

Together, SCM and Randek offer the largest range of technologies for glulam structural beams, columns, CLT wall and floor elements, as well as prefabricated walls, roofs and trusses.

In particular, the SCM team will present its solutions best suited to these building components: the CNC machining centers OIKOS XL and OIKOS XL+, dedicated to the production of structural columns and AREA XL, for large format CLT panels; regarding sanding and calibrating for CLT panels, the new highly modular sanding-calibrating machine DMC SYSTEM XL.

Mass Timber Conference attendees will also get a chance to see the Area XL in person during one of the organized building tours, specifically the Western Oregon Tour 3#, which will visit Freres Engineered Wood, our customer that specializes in Mass Ply panel production.

The OIKOS XL is the “extra-large” innovative, 6-axis CNC machining center designed to produce large-sized glulam beams and columns with a maximum cross-section of 1250x500 mm. 

The company said one of its main advantages is the automatic management and processing of heavy elements using the sturdy mechanical structure and reliable locking and handling systems. This feature is a part of the 6-axis technology, which allows machining on all six faces of the element with all tools available and with no rotation or repositioning required. 

The machining accuracy and special anti-scraping devices create power and flexibility that produce a perfect quality of the finished elements. OIKOS XL+ is the new CNC machining center for the production of columns and structural beams with a max. cross-section of 1250x610 mm. This solution has inherited all characteristics of OIKOS XL, amplifying all its advantages, thanks to the implementation of a second independent machining unit with a 1,150 mm diameter saw blade. 

In line with the increased expansion of multi-story wooden buildings globally, OIKOS XL+ is designed to overcome even the most complex challenges. The robust and adequately sized structure of the machine means very heavy elements of up to 4 tons can be processed, as well as very hard materials. 

Productivity and precision are other primary requirements that are the basis of this model. The second 5-axis saw blade unit allows a blade radius of an impressive 400 mm. Furthermore, the use of a saw blade rather than a chainsaw aggregate means to work faster and achieve a better quality. 

Another advantage is the ability to execute cuts from bars with a maximum thickness of 610 mm. Decisive is the machining strategy behind the OIKOS XL+, which combines the second saw blade unit with the main machining unit that has a 740 mm diameter saw blade.

AREA XL: state of the art technology for large format CLT panels

The Area XL is the 5-axis CNC machining center for the industrial production of large format CLT panels. This solution, which represents an evolution of the renowned AREA model, is developed to meet the requirements of companies looking for high productivity, accuracy and reliability. 

The processing of large format CLT panels is characterized by heavy duty stock removal, process automation, as well as maximum cleaning of the work area.

AREA XL is designed taking into consideration these specific requirements. With this machining center, size and thickness of the CLT panels are no longer a problem. Elements up to 16,000x3,600x400 mm can be processed, thanks to a high-power operating unit: 63 kW in continuous service. The overall productivity can further be increased by adding a second operating unit, to perform specific operations in parallel with the first one. Another plus of the machine is the possibility to perform crosswise throughfeed-drilling even on the maximum panel size with optional auxiliary units. 

Moreover, AREA XL offers up to 60 tool stations, including two sawblades for each operating unit. The operator’s work is made even easier, thanks to the automatic workpiece handling and positioning systems and innovative cleaning systems. And last but not least, AREA XL also allows to work in total safety, thanks to the full enclosure and a protected access system to the work area through laser barriers.

New HMI Maestro active beam&wall for quick and easy all-round control
Further enhancing OIKOS XL, OIKOS XL+, AREA XL and all the other SCM cnc machining centers for timber construction Maestro active beam&wall is the new human-machine interface software, which offers numerous functions in a simple and fast way. 

The new version of the HMI software is characterized by a totally renewed graphic interface aligned with that of the latest generation of software. Maestro active beam&wall is based on Maestro active, the HMI software adopted by the entire SCM Group for complete job order management.

Last but not least, the presence of the new eye-M top plus operator console compatible with all models in the Area and Oikos ranges. On the same console, upon request, the Maestro beam&wall programming software can also be installed, closely connected to the HMI software. The possibility of using Maestro beam&wall both on a PC in the office and on the operator console, i.e. directly on the machine even for the programming phase, is an important advantage for companies that reckon on flexibility of use to increase their productivity.

The SCM project with DMC SYSTEM XL, automatic sanding-calibrating specifically designed for timber construction industry, now enable to process both top and bottom face of CLT.

The SCM project with DMC SYSTEM XL, automatic sanding-calibrating specifically designed for timber construction industry, continue with new units in addition to those already available (roller, pad and crossbelt units) to further enrich the machine by enabling to process both top and bottom face of CLT panels up to 3.700 mm wide and 500 mm thick.

These new modules (bottom roller unit, top/bottom pad unit and “piggyback” crossbelt unit) can be fully combined and integrated with each other according to the customer's production requirements, by offering high configuration versatility (a distinctive plus of DMC SYSTEM XL) and unification of components and common parts to optimize operating costs.

The solid steel structure is designed to last and withstand the most intense machining, by granting zero-vibration. Furthermore, the automatic sanding-calibrating machine is developed to make the operator's maintenance work easier, faster and always safer.

Energy saving is key

The machine is specifically engineered with an optimized design and technological solution for minimum compressed air consumption.

This solution, as well as all SCM sanding features, is aimed at improving the surface finishing and increasing the value of the finished product. By doing so, customers can reflect the latest market trends in having visible CLT walls and an end-product that is as natural as possible (without resorting to additional surface treatments).
