Wood-Mizer releases the new high-tech WM4000 sawmill

Wood-Mizer releases the new high-tech WM4000 sawmill
Wood-Mizer has announced the release of their new WM4000 thin-kerf industrial sawmill, which they are calling the ‘next generation’ in sawmills. The WM4000 combines the profitability enhancements of thin-kerf blades with productivity advances in automated sawing technology to create an ideal solution for wood producers in the again growing timber industry.

Similar in overall design to Wood-Mizer’s industrial WM3500 sawmill, the WM4000 features are more heavy duty and more productive in many ways.

New control station design
Productivity starts with the operator. With this fact in mind, the WM4000 features a new 7.5" (19cm) HMI touch-screen which presents more information to the sawyer. Board and cant sizes are displayed along with current head height, feed position, and blade power. Amongst a host of new productivity-enhancing features, the sawyer’s favorite has been the Auto-
Cut feature, which remembers the location of the start and end of the log. Instead of the sawyer overshooting either end of the log, the sawhead knows how far to cut, and where to return to, and as a result spends more time sawing.

The new deluxe joysticks provide the operator with precise control of all sawing and log handling functions, and feature proportional hydraulic speed control. They can be configured to save two different sawyers’ personal joystick preferences.

The sawing head
A new servo motor controls the vertical head height, and increases the head up/down speed and positioning precision. Larger blade guide rollers provide the blade more support in the cut.


The hydraulic speed is adjusted proportionally to the operator’s pressure applied to the joysticks during use.

The standard hydraulics features on the WM4000 are:
- Two redesigned bi-directional chain turners for log positioning
- Three vertical side supports (Up to 6 optional)
- Powered taper rollers

Sawmill bed and material handling system
The stability and durability of the mill is increased thanks to the bed rails and frame now featuring 50% more steel. A new built-in powered board conveyor automatically turns itself off after moving a board or cant from the sawmill towards an edger or resaw, reducing daily power consumption.

New! Maintenance and troubleshooting

The HMI touch-screen computer comes with a robust set of diagnostic capabilities, and troubleshooting the system can be accomplished via the onboard Ethernet connection.

The WM4000 has taken the flagship position as Wood-Mizer’s most productive thin-kerf sawmill on the market, providing new opportunities for the larger profit margins that Wood-Mizer has historically offered the lumber industry.

The WM4000 is designed to work as the principal breakdown saw in Wood-Mizer’s line of industrial wood processing equipment and is also able to be integrated into existing operations.
