Four Finished Surfaces. One Productive Pass.

The Boss Tetra is a heavy-duty four-sided planer designed to size and finish lumber efficiently in one continuous pass. Its four-spindle configuration machines the bottom, sides and top of each work-piece, transforming rough stock into accurately squared material ready for downstream production. Powerful spindle motors, automated positioning and variable-speed feeding make the Boss Tetra an ideal solution for manufacturers seeking dependable output, repeatable dimensions and faster changeovers. 

Digital Control Features

  • Syntec PLC control system
  • 10-inch HMI touchscreen
  • Four-axis digital control
  • Servo-driven spindle positioning
  • Automatic feed-beam positioning 
  • Storage for up to 200 production settings
  • SIKO digital position readouts

These features support repeatable setups, reduce manual adjustment and help maintain consistent dimensions across production runs.

Automated Width and Thickness Control

The Boss Tetra is engineered for the accurate production of squared, four-sided material. Servo-controlled positioning automatically adjusts the left-side and top spindles, while motorized positioning of the infeed table and fence helps streamline product changeovers.

A laser projection system provides a real-time indication of the finished width and thickness, allowing operators to verify the intended final dimensions before machining begins.

Built for Reliable Daily Production

The Boss Tetra combines heavy-duty construction with practical systems designed to support uptime and repeatability. Servo-controlled spindle adjustments improve positioning accuracy, while digital readouts give operators clear references during setup and operation.

Expand Beyond Standard Four-Sided Planing

Axial positioning allows planer heads to precisely align profile tooling with the work piece, expanding the machine beyond stan dard four-sided planing to produce custom profiles in a single pass. This added flexibility reduces secondary operations, setup time, and material handling while increasing overall productivity.

Precision Spindle Adjustment

Precision linear bearings and a THK guide sys tem provide smooth, rigid, and highly accurate spindle adjustments. This ensures repeatable positioning, reduced vibration, and consistent machining quality throughout the machine’s service life.

Frequently Asked Questions

What is the BOSS Tetra designed for?

The BOSS Tetra is a heavy-duty four-sided planer designed to size and finish lumber in one continuous pass. It machines the bottom, sides, and top of the workpiece to produce accurately squared material ready for downstream production. 

What digital control features does the BOSS Tetra offer?

The machine features a Syntec PLC control system, 10-inch HMI touchscreen, four-axis digital control, servo-driven spindle positioning, automatic feed-beam positioning, storage for up to 200 production settings, and SIKO digital position readouts. 

How does the BOSS Tetra maintain machining accuracy?

The Tetra uses precision linear bearings and a THK guide system for smooth and rigid spindle adjustments. Servo-controlled positioning and digital readouts also help provide repeatable positioning and consistent machining quality. 

How does the BOSS Tetra improve production efficiency?

The Tetra combines four-spindle machining, variable-speed feeding, automated positioning, and digital controls to provide dependable output, repeatable dimensions, and faster changeovers. 

Can the BOSS Tetra produce custom profiles?

Yes. Axial positioning allows planer heads to precisely align profile tooling with the workpiece, enabling custom profiles to be produced in a single pass. This can reduce secondary operations, setup time, and material handling.
