Flexibility and precision in woodworking

A use case for sawing stations and clamping devices with ZIMM

Wood is a variable natural material: strength, density and knot zones vary from workpiece to workpiece. In practice, this means fluctuating cutting forces, potential misalignments and unnecessary waste – especially at high cycle rates. To keep processes stable, an adjustment mechanism is needed that controls shock peaks, protects tools and still positions them precisely and repeatably. This is exactly where the combination of an electromechanical actuator and load damper (LAD) comes in.

A compact, robust system moves clamping and guide axes precisely – quietly, with low maintenance and integrated safety functions. The focus is on consistently straight cuts with varying workpiece thicknesses, high availability in shift operation and easy integration into existing machines.

The challenge: Straight cuts with variable workpiece thicknesses

Fluctuating wood thicknesses and knot zones lead to varying cutting forces, misalignments and increased wear. Unforeseen blockages put strain on the drive and saw blade, compromising process stability.

The solution: Actuators with load dampers (LAD)

Electromechanical actuators position the adjustment axes precisely. The LAD acts as a physical buffer: shock peaks during block movements are mechanically absorbed; the control system uses the defined spring travel to switch off/brake. The result: straight, repeatable cuts and protected tools – clean and low-maintenance, without any hydraulics.

The application scenario: Sawing stations & clamping devices

In sawing stations and clamping devices with varying wood thicknesses (e.g. knot zones), the cutting position remains stable and the process stays on track. Short-term resistance peaks are mechanically absorbed, the system maintains speed and dimensional accuracy; feed and trimming continue smoothly. This reduces unplanned stops, protects saw blades and ensures reproducible cutting quality across
entire shifts. Ideal for lines with high cycle rates, new installations and retrofits.
