For intelligent sawing
Too bad all machines are not as intelligent as the HOLZ-HER ZENTREX 6220 series:
Automatic, infinite cutting height adjustment
- The optimum saw extension is calculated using the stack height measured by the pressure beam and the adjustable saw blade protrusion.
Optimized automatic cutting length feature
- The sawing carriage is controlled by this optimization feature. The start and end of the cut are calculated, allowing the sawing carriage to be prepositioned beneath the panel.
Motor-driven groove height adjustment
- Adjustable groove depth from 0 - 130 mm programmable on control and optimization. Adjustment is accomplished using a recirculating ball screw in the 0/1 mm range, including grooving software with graphic support.
- The bidirectional grooving feature (FCM - Fast Cut Mode) - achieves the shortest possible cycle times for grooving. On HOLZ-HER machines, grooving is also accomplished during sawing carriage return!
Electrical prescoring saw adjustment
- Allows simple and perfect adjustment of the prescoring saw on the monitor, in the shortest possible time, with minimum effort.
- The positions of the saw blades in relation to the tool and then to the material are saved, eliminating additional adjustment work when changing tools for various materials, etc.
- The grooving and cut-out equipment allows grooves, window or corner cutouts to be made including programming software with graphic support.
Intelligent workpiece clamps
- The workpiece clamps are controlled by an optimization feature (or manually). Only the workpiece clamps actually required to clamp the specific panel/stack are closed. This saves a great deal of pneumatic energy and reduces cycle times for closing.
Angle pressing device, double version
- The alignment force is automatically preprogrammed using the material (parameters) and stack height for optimum prepositioning. This eliminates waiting times when aligning the panel strips against the angle guide.
Solid air cushion tables
High functionality – perfect ergonomics
The equipment and possible options on the ZENTREX 6220 are defined by demanding industrial standards.
- The machine table is equipped with air nozzles to form an air cushion before and after the sawing line, ensuring easy and gentle panel handling.
- The air cushion tables (1,800 mm) are supported directly on the body of the machine and can be adjusted - on the mobile version - easily to the material dimensions and height of the operator.
- Extremely stable design of air cushion support tables for exceptionally heavy stacks of panels.
- The support tables can be moved very easily for workpieces with small dimensions or to obtain additional space.
- Lateral and front mounted feed rollers on the support tables provide for smooth, ergonomical and easy feed to the saw.
Powerful sawing units up to 25 kW
High Power – Extremely Smooth Operation
The patent-pending sawing unit is distinguished by its performance, precision and enormous cutting power. The saw blade is moved to the desired height in seconds by the servo-motor. Here the powerful drive motor remains in position and does not have to be raised. This allows the saw to be moved infinitely to grooving depths and saw blade protrusions up to 130 mm at enormous speed. Panel stacks up to 120 mm can be cut easily by the high power motors.
The prescoring saw can be adjusted under program control using the servo-technology. A postforming saw for material thicknesses up to 50 mm with drive power of 3.0 kW is also available as an option.
The solid layout of the machine column and ideal triangular power transfer together with ground and hardened linear guides and brushless servo-drives on all axes allow massive stacks to be cut to perfection.
TwinPress – two-sided angle pressing device
Two-sided angle pressing device (program-controlled) - for short cycle times
Scope of functions:
- TwinPress – applies pressure to both sides of the workpiece in front and in back of the sawing line
- Servo-controlled – automatically pre-positioned
- Pressure length: 35 – 2,200 mm for gentle material handling
- The rotating pressure roller prevents damage to the workpiece
(optional on ZENTREX 6220 classic).
Freely programmable rip fence
Precision guided, freely programmable rip fence on linear guides with dynamic servo-drive. Up to three double finger clamps in stop area allow narrow strips to be cut simultaneously. Floating-type workpiece clamps compensate for tension in the panel stacks toward the top.
Floating workpiece clamps
The floating workpiece clamps mounted on double linear guides move the material to be cut into position powerfully and precisely. The programmable pressure and intelligent clamps guarantee careful handling. The corners and edges of the panels are handled carefully to prevent damage even to sensitive material. The optional measuring system on the clamps allows even faster cutting times. It transfers the material thickness directly to the control for precise positioning of the pressure beam right from the start.
Optional controlled stops are available for precise cutting on unveneered workpieces.
Remnant cutting device integrated into the pressure beam
Remnant cutting device in pressure beam - the clamps retract into the grooved pressure beam. This allows panels to be cut completely without remnants for perfect utilization of the entire panel.
Optimization module EASY-PLAN
EASY-PLAN – The name is the program
The EASY-PLAN optimisation software installed as a standard feature provides all functions, such as:
- Entry of material data and parts list data
- Job summary
- Cutting plan survey for optimized jobs (representation at one level)

HOLZ-HER and Zottler: Styrian Connection
The Zottler Cabinet Making Shop in Styrian, Austria, handles all types of classic construction and furniture making work. Their operations depend on machines from HOLZ-HER for universal applications.
[...] As a master cabinet maker, Zottler builds high quality furnishings for residential dwellings, hotels and restaurants as well as complete furnishings for retirement and nursing homes and student dormitories for customers in Austria, Germany and Switzerland. “Recently we just completed 250 kitchens as well as the complete room furnishings for student dormitories in Graz’s CoolCity [...] For the team with its 48 employees working like a small industrial mass-production shop in two-shift operation, failure of a machine would be disastrous. During the last 5 years a great deal of time has been spent developing efficient processes and a bundle of money invested in state-of-the-art machines to ensure that these processes run smoothly.
What brought you to HOLZ-HER? Zottler: "After the initial period nearly ten years ago, we were confronted with the decision whether to spend a lot of money to convert the old panel saw or just buy a new one right away. We made a foresighted decision. An existing contact recommended HOLZ-HER. And ever since that time, Zottler has invested regularly in new machines from the plant in Voitsberg, which is only an hour’s drive, “because when it comes to our essential machines, we only want one company to contact, who needs to be in the vicinity and offer true Austrian quality.” And if things ever get really critical, interjected Peter Gadi, Regional Sales Manager at HOLZ-HER and responsible for the projects at Zottler, we send a service technician to Passail immediately to solve the problem.
The extensive machine park from Holz-Her, now in use at the Zottler Cabinet Making Shop, covers all processing steps for mass-produced furniture, thus ensuring continuous work flow: [...]
