Twin Vertical Saw.

Twin Vertical Saw

Developed for the Wood-Mizer Smart Log Processing line of equipment, the TVS removes two sides of a log in one pass. The maximum log diameter that can pass through the TVS is 16", and the maximum cutting width is 9.75". The tilted heads help maximize blade life and allow easy slab removal onto an optional cross transfer deck. The heads are designed for easy blade changes and maintenance. The proven, belted wheels and 184" blade length capitalize on blade life and maintain cutting accuracy while the industrial-grade motors provide proven performance and reduced energy costs. The TVS takes two sides off a log, which can then be passed on to the SVS, and then on through the horizontal resaws to recover as much lumber as possible.


Logs are loaded and turned manually with a cant hook. An optional log loading kit includes a manual winch and log loading ramps to assist with lifting logs onto the bed. Once loaded, logs are secured by six side supports and two fully adjustable log clamps that tightly clamp the log and allow for cuts within 1" of the bed. To prepare for cutting, head height is precisely positioned by a quick turn of the up/down dial and the blade is effortlessly engaged with a handle. Cutting is accomplished by steadily advancing the sawmill head along the length of the log by turning a low maintenance, hand-crank feed system which runs on a rope instead of a cable. A power feed is available as an optional upgrade. Once the cut is completed, the head is raised up, pulled back and lowered into position for the next cut. A water tank feeds lubrication directly to the blade to improve cutting performance and keep the blade clean. The adjustable blade guide arm keeps the blade well supported while cutting various sized material. Blade tension is easily adjusted, and keeps the blade at the proper tension for cutting.
