Wood Processing Machines

Wood processing machines are just as varied as the raw material itself. Whether we are talking about milling profiles and battens or cutting plates and boards, the different machine requirements demand a high level of flexibility in drive technology. This is exactly where KEB Automation steps in. From controls with numerous software features to the processing of any machine process data, and from drive inverters to motors with gears and brakes, KEB is your powerful partner when it comes to wood processing.

You can use our system solutions with complete confidence. Safety features such as a safely limited speed and direction of rotation, or safe standstill detection ensure optimum protection.

  • Automation with comprehensive safety technology.
  • Switching different motors on one inverter.
  • Electronic filters for the use of residual current protective switches.

System Solutions

Material Processing

Stationary CNC machines

CNC machines are the “premium class” of machinery in the wood processing industry. Fast reaction times and high precision on the workpiece are just some of the many demands that KEB has tackled in the past.

Through-feed machines

Dynamic movement, just in time, without obstructing the workflow – while maintaining precision synchronously with the workpiece. With its dynamic drive solutions, KEB provides the perfect answer to these requirements.

Surface Treatment

Sawing, drilling and milling

Optimum cutting capacity requires high and, at the same time, constant speeds. Even with changing loads, it is important that speeds remain constant in a controlled manner. KEB's system solutions take care of this for you.

Grinding, polishing and varnishing

Some of the most important steps during the surface treatment of wood are grinding, polishing and varnishing. The finishing process is what gives an item of furniture its final look, for example, and is therefore the best advertisement for the final product. Meticulous work is particularly important here – along with drive technology, which makes it easily possible.

Solid Wood Processing

Panel-sizing technology

When it comes to the dimensionally accurate cutting of wood, panel-sizing saws are used in a wide variety of designs. The millimetre-precise cutting of wood panels demands a high degree of precision, and requires drives with special dynamics. KEB’s drive solutions are not only used to drive saws, they are also equipped with important safety features and contain well-established control programs. 

Saw mills

Wood shavings and dust create harsh and challenging environments for machines and components in saw mills. In these conditions in particular, driving motors without sensors is a great advantage. KEB does this with its specially developed ASCL or SCL technology. KEB’s asynchronous and geared motors also meet the demands of saw mills as real working machines. Available as helical, helical bevel, helical worm, flat or planetary gears, larger outputs can easily be achieved thanks to the gear solutions. 

Recycling wood leftovers

In many cases, wood that is not of a suitable quality or condition to be further processed into final products by no means remains unused. Instead, it is further processed as part of the recycling of wood leftovers, for example as a source of energy. The machines required for this purpose benefit from KEB’s high torque motors, among other things. These are high-frequency gearless motors that can operate at low speeds. An added advantage is that virtually all types of motors can be operated using KEB’s drive solutions.

Transport and Handling

Material handling/transport systems

The path from wood as the raw material to the finished workpiece passes through various processing steps along the way. For example, it is not uncommon for roller conveyors to assist in organising the onward transportation of the wood. KEB system solutions are used to position the conveyors without the use of sensors. Stations can have completely different demands such as a rotary cone which requires a dynamic drive to generate a sufficient acceleration phase in order to rotate the workpiece.

Panel storage systems

During the course of material procurement, panel storage systems are regularly used for example, for stacking wooden panels for further processing. KEB’s controlled drives, brakes and geared motors make sure that this step runs smoothly. In particular, motors from KEB’s TA series are provided for this purpose. These servo gear motors, which are mechanically-graded into five different sizes, are truly outstanding with their cutting-edge servo technology and wide range of rated voltages and speeds. 

Assembly aids

Furniture presses are a classic assembly aid in the wood processing industry. They perform various handling tasks from clamping workpieces together to holding them in place and opening them back up again. With the COMBIVERT G6 frequency inverter, KEB provides a drive solution that carries out these tasks by changing the parameter sets in the inverter. The G6 eliminates the need for an entire control system, thereby reducing the installation workload and costs for the user.



Sensorless closed-loop operation and maximum dynamics – without lowering speed during load fluctuations. This is made possible by KEB’s sensorless control methods ASCL (Asynchronous Sensorless Closed Loop) and SCL (Sensorless Closed Loop), regardless of whether asynchronous, synchronous, synchronous reluctance or IPM motors are involved. With ASiCL (Asynchronous single current closed loop), KEB also provides a complementary solution which ensures excellent shaft performance with high torque even in the low-speed range. The motor model also takes care of positioning during subordinate positioning tasks.

Functional safety

Electrical machines and systems are subject to increasingly stringent safety requirements. Simplify your safety concept with the KEB drive controller’s integrated safety functions. Speeds, positions and various other functions are monitored directly in the drive electronics. The KEB safety control integrates the requirements of safety technology into the functional control environment. Safe communication with the control level serves as a widely used and established FSoE (Safety over EtherCat) solution – alternatively, communication via ProfiSafe is also available. In addition to, or instead of, a safe field bus system, individual safety functions can also easily be switched on and off via digital inputs. With the certification of sensorless safety functions, in some cases speed-related functions can also be implemented without a sensor system.

Fire safety

Leakage currents from as low as 300 mA can start a fire, therefore suitable 300 mA residual current protective switches are mandatory, especially in woodworking machines. With filters such as the E6, we ensure that the frequency inverters connected to the protective switches do not generate a leakage current. The advantage is that it is possible to immediately connect a large number of inverters to an existing residual current protective switch. This lowers the costs as the need for additional protective switches is significantly reduced.


In order to set up a complete CNC solution, a comprehensive concept containing coordinated hardware and software components is required. This starts with IPC-based control technology and the appropriate visualisation, and ranges from drive controllers with integrated safety to motors and gearboxes. You will be particularly impressed by highly dynamic drives, consisting of the TA geared motor series and the 6-series inverter generation, as a flexible solution with high overall efficiency.

High-speed applications

Whether for asynchronous, synchronous, synchronous reluctance or IPM motors: All types of motors can be controlled and operated highly dynamically without encoders by the COMBIVERT F6 or COMBIVERT S6 drive controllers at high speeds of up to 120,000 rpm using the ASCL or SCL method. Depending on individual requirements, this is possible with or without encoder. This means that nothing stands in the way of using motors in high-speed applications.

Safety brakes

Safe holding in all positions. Accident prevention is a top priority and must be ensured using appropriate products and controls. KEB offers various solutions in this area which, in the event of imminent danger, bring the drive safely to a standstill via an emergency stop and reliably hold it in position when the motor is at a standstill or in the event of a power failure.

The technology behind safety brakes

Thanks to frictionally or positive connection the COMBINORM products are particularly suited for precise positioning and reliable holding.

Safe release function without residual torque and no maintenance throughout their entire service life complete the performance.
