TVS Twin Vertical Saw

The TVS (Twin Vertical Saw) is a primary processing machine designed to simultaneously remove two vertical sides from logs up to 400mm in diameter in a single pass. It employs thin-kerf blade technology to minimize material loss while maximizing throughput, making it a critical first-stage processing tool for sawmills converting raw logs into dimensionally consistent lumber or cant material. Operationally, the TVS combines adjustable feed speeds from 0–25 m/min with five presettable width positions (setworks), enabling operators to optimize cutting parameters based on log diameter, wood species, and desired output dimensions without manual blade repositioning between cuts. The thin-kerf design reduces kerf loss compared to conventional blade specifications, directly improving recovery rates—a key metric in primary milling economics. The machine handles straight logs, curved logs, logs with flat surfaces, and slabs with equal effectiveness, providing flexibility across diverse raw material conditions. The TVS functions effectively as both a standalone primary processor and as an integrated component within larger sawmill production lines. Its movable control stand centralizes feed speed and setworks adjustment, allowing operators to manage cutting parameters from a single station without navigating between machine points. This design reduces operator fatigue during extended production runs and supports rapid setup changes between log batches. The machine is engineered for medium to industrial-scale operations processing 100+ logs per shift, where recovery optimization and consistent dimensioning justify equipment investment. It is particularly suited to mills processing logs in the 300–400mm diameter range, where twin-side removal in a single operation significantly reduces downstream processing steps and labor requirements compared to sequential single-blade cutting methods.
