Wood-Mizer introduces the MR250 Double Arbor Multirip – an advanced gangsaw engineered for high-performance, precision cutting in industrial sawmilling operations. Designed for speed, flexibility, and superior recovery, the MR250 is a powerful solution that meets the needs of modern production environments. With the capacity to handle material up to 650 mm wide and 250 mm thick, and accommodate up to 32 circular blades (16 per shaft), the MR250 delivers exceptional throughput with minimal waste.
Built for demanding conditions, the MR250 is capable of cutting 3- and 2-sided cants with ease, thanks to a detachable side fence and integrated laser sight system that ensures precise alignment. Operators can choose to install up to three lasers to further enhance accuracy. With a wide range of cutting parameters—from a minimum material thickness of 38 mm to a maximum of 250 mm—the MR250 adapts to a variety of wood species and sawing tasks.
The machine features 2-meter infeed and outfeed tables that are extendable as needed, along with optional driven rollers and a centering system for smooth and efficient feeding. Safety is a top priority, featuring bottom and top anti-kickback fingers, a limit bar with a safety shut-off switch, and a manual lever to reverse the material in the event of jams.
One of the standout features of the MR250 is its fully electric adjustment system. Both the arbors and the press roller head are regulated automatically via Setworks or manually using a dedicated mini control panel. This system ensures that the head presses down and the arbors center themselves according to the cant thickness, all in a single operation.
The MR250 utilizes blades with a diameter of 300–400 mm, and customers can select spacers to achieve the desired cutting width according to their production goals. Blade and spacer configurations are selected according to individual requirements.
All material waste is efficiently managed by an integrated wood chipper, which transfers chips to dust extraction chutes placed underneath and on the sides of the machine. The MR250 includes a total of eight driven feed rollers—six at the bottom and two at the top—supported by proximity sensors that detect material presence and ensure uninterrupted operation. Once feeding begins, safety mechanisms lock the adjustment systems to prevent accidental changes.
Each arbor is powered by an independent electric motor, with available configurations ranging from 22 kW to 55 kW, depending on the required production capacity. The main motor powers the chipper, while a separate 1.5 kW motor drives the feeding system. Additional motors manage the adjustment of the arbors and press rollers.
An ergonomic remote operator panel provides easy access to all essential controls, including emergency stop, feed direction, speed adjustment, and blade positioning. An optional Setworks display enhances precision and repeatability during operation.
With its rugged design, intelligent automation, and flexible setup, the MR250 Double Arbor Multirip is a vital asset for industrial sawmills seeking to boost output, minimize waste, and enhance operational safety. Whether integrated into an existing production line or used as a standalone machine, the MR250 redefines what’s possible in industrial wood cutting.
