Overview

The SVS Single Vertical Saw is a specialized primary processing machine designed to remove the third side of a log during cant preparation, positioned downstream of the TVS in a typical sawmill workflow. It bridges the gap between initial log breakdown and multi-blade resaw processing by squaring and dimensioning material to optimize recovery in subsequent milling stages. The machine accommodates material up to 400mm wide by 250mm high, with a maximum cutting width of 300mm, enabling operators to process cants and large dimension lumber in a single pass. Material movement is controlled via a steel spiked chain belt feed system capable of 25 meters per minute, supported by integral infeed and outfeed roller tables that ensure consistent material presentation and evacuation. A standard laser alignment system allows operators to position cuts with precision, reducing setup time and minimizing manual adjustment errors during production runs. The SVS targets medium to industrial-scale sawmills and primary timber processors that run cant-through-board workflows and require consistent third-side dressing before resaw operations. It is particularly suited for operations processing softwood and hardwood species where initial log breakdown must be followed by precision dimensioning to maximize yield. The machine's capacity and feed speed align with mills operating at 8–16 hour daily production cycles with output volumes of 20–40 cubic meters per day. Within its product class, the SVS provides a cost-effective alternative to multi-blade edging systems by combining simplicity with sufficient capacity to handle premium dimension material. Its single-blade design minimizes blade inventory complexity while the high feed rate (25 m/min) maintains throughput parity with integrated mill lines, making it ideal for retrofitting into existing primary processing sequences or as a standalone sizing operation.

Applications
cant dressing resaw prep
Industrial
The SVS removes the third side of logs after initial breakdown, squaring cants to 400mm × 250mm maximum dimensions before multi-blade resaw processing. This operation is critical in high-throughput mills where consistent cant geometry directly impacts resaw recovery rates and board yield, making the machine essential for mills targeting 60%+ overall recovery in softwood and hardwood processing.
dimensional lumber sizing
Medium workshop
Medium-scale sawmills use the SVS to trim and square large-dimension cants (300mm maximum cut width) to specification before shipment or internal reprocessing. The 25 m/min feed rate and precision laser alignment ensure repeatable sizing with minimal operator adjustment, reducing labor cost in operations processing 15–30 m³ daily.
specialty hardwood processing
Medium workshop
Hardwood mills processing premium logs use the SVS to dress and square cants with precision before resawing into high-value boards, flooring blanks, or specialty stock. The laser alignment system and controlled 25 m/min feed speed minimize saw marks and dimensional variation, critical for species like oak, maple, and walnut where appearance grade and tight tolerances command premium pricing.
primary processing integration
Industrial
In integrated primary processing lines, the SVS functions as a positioned squaring tool between log breakdown (TVS) and resaw stages, automating the removal of wane and irregular edges from cants up to 400mm wide. The machine's infeed/outfeed roller tables and high feed speed (25 m/min) enable continuous operation with minimal material handling, supporting mills operating 8+ hour production shifts.
