Elevating table for stack processing
The lift version includes a precision, chain-driven lifting table for high material through-put as a standard feature.
Solid, precision lifting table for high capacity mass production. The small space requirement and enormously high supporting capacity of 3,5t enable high-speed processing at high material throughput rates using stack cuts. A scissors-type lifting table with supporting capacity of 7t and charging height of 1,100 mm for installation in a pit is available for extremely heavy materials or large panel stacks. It is also possible to install the 7t scissors lifting table without pit for moving panel stacks up to 550 mm. Select the suitable version for optimum integration into your production process.
The servo-controlled lifting table with electric drive offers all advantages of a self-supporting platform combined with the advantages of a spindle-driven lifting table!
- Panels with thickness over 9 mm (16 mm scissors lifting table) can be positioned precisely and pushed off.
- High speed lifting / lowering cycles
- Symmetric charging is not required (optimum working conditions in front of saw!)
- No rigid connection to saw (eliminates damage)
- For panel formats with length up to 4,100 mm and width up to 2,200 mm (widths up to 2,500 mm also possible as option).
Side loading device
Side loading device
The lifting table for the pressure beam saw can be loaded using the side roller conveyors. This provides a variety of advantages for the user:
- The large motion path for the stacker at the rear of the machine is eliminated.
- While loading the roller conveyor, cutting work can simultaneously be accomplished on the machine.
- The right/left selection allows one roller conveyor to be used for loading and the other for discharging the unused stack.
Various scenarios can be configured alternatively:
- Right | Left | Right + Left
- Right + Rear | Left + Rear
- Right + Left + Rear
The loading device can accommodate the following dimensions:
- Stack heights up to 550 mm via side feed roller conveyor
- Stack length: up to 4,200 mm
- Panel depth: up to 2,200 mm (optional 2,500 mm)
Thin panel pusher unit
Most production shops process highly varying materials and material thicknesses. All panels require reliable manipulation for the process regardless of frequent tolerances. The machine needs special equipment to reliably push thin or wavy panels from the lifting table. This is where the thin panel pusher unit is used allowing panels with thicknesses as low as 4 mm to be pushed off. This unit can compensate up to 25 mm waves in the stack.
- Max. stack height: 50-80 mm (depending on waviness)
- Max. waviness: 25 mm
- Min. panel thickness: 4 mm (+/-0.2 mm)
- Stacking accuracy: +/-50mm (panel offset in stack)
- Min. panel length for pushing off: 2,100 mm
Laser supported positioning system
Laser-supported display system for error-free part identification.
For panel sizes, whose length is difficult to differentiate from its width in spite of 3D simulation, the ZENTREX 6215 now offers a laser positioning system with accuracy down to the millimeter. Your advantage: Remeasuring panels or incorrect positioning in the machine is a thing of the past. Moreover you minimize incorrect cuts and reject parts.
2-stage evacuation management system
Maximum evacuation power using synergistic effects of individual “Dust Control” and “Clean Protection” features
Dust Control – for program-controlled evacuation
The cutting position recognition feature optimally controls all evacuation openings in the pressure beam. This always ensures maximum evacuation power directly at the saw blade, keeping your machine table free at all times. Evacuation openings not required are closed automatically - can, however, be adapted manually on the control to ensure your machine table is always clean.
Clean Protection – for scoring cuts
When making scoring cuts, an intelligent, moving evacuation unit behind the saw blade prevents chips and dust from being hurled out unchecked during the cutting process. This keeps your machine table clean even during extremely narrow scoring cuts.
A perfectly designed workplace provides the basis for efficient, non-fatiguing work. With the 21.5" control terminal HOLZ-HER panel cutting saws satisfy all requirements placed by machine operators. The ergonomically adjustable rack offers space to position up to two printers, scanner, keyboard and mouse where they are located perfectly for the operator.
The control center with large multi-touch 21.5” full HD monitor with 16:9 format guarantees maximum clarity with real time 3D graphics and full graphic finalization help.
The CUT CONTROL 2 control package
The high performance software package for large HOLZ-HER industrial saws

Cutting line closure devices
The cutting line closure devices prevent trim cuts or narrow strips from falling down and jamming in the saw slot and the saw carriage. The strips can be easily removed by the operator directly after the cut. The cutting line closers are all individually controlled and close after the saw blade has passed by. The process takes place automatically via the control system.
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
- Infinitely regulated pressure (starting with 0 Nm) for thin and easily deformed materials. It is possible to simply position the angle presser unit on the workpiece without pressure.
- Alignment width: 35 – 2,200 mm for gentle material handling
- The rotating pressure roller prevents damage to the workpiece
Line laser for cutting line
The Visible Cut Line uses a laser beam to indicate the exact cutting line. This also allows cuts according to a manual sketch to be positioned and cut perfectly. Naturally this device also provides a major advantage when cutting real wood (e.g. edging).
XL - Paket
The XL package equips the ZENTREX 6215 for high-performance use.
With a saw blade projection of 130mm and the massive industrial collets, the machine reliably cuts large panel packages or heavy individual panels.

Powerful sawing units up to 21 kW
High Power – Extremely Smooth Operation
The patent-pending sawing unit is distinguished by its performance, precision and enormous cutting power. The servo-motor with recirculating ball spindle from CNC technology moves the saw blade to the desired height in seconds. During this operation the high power main motor remains in its fixed position and is no longer raised. This allows the saw to be moved infinitely to grooving depths and saw blade protrusions up to 115 mm at enormous speed. Panel stacks can be cut easily by the high power motors. The main and prescoring saw blade is guided by a linear guide as it moves up and down.
The prescoring saw can be adjusted under program control using the servo-technology. A postforming unit for material thicknesses up to 50 mm with drive power of 2.2 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.
Perfect triangle of forces
The HOLZ-HER sawing unit runs on hardened and covered linear guides as a standard feature. The guide is located precisely where the panel material is being sawed.
The cutting forces are dissipated linearly in the middle of the sawing unit. Perfect power triangle at the cutting line for permanently ideal sawing performance thanks to sophisticated design of the sawing carriage guide and maintenance-free rack-and-pinion drive.
Our new "Security Package" guarantees particularly safe operation on and around the machine!
