CUT SAWS
SP720 Series Cut Saws
One saw, every timber build.
The SP720 series is Randek’s crosscut saw platform. It is reliable, flexible and easy to use. Whether you produce roof trusses, wall and floor elements, whole prefabricated houses, or work in a joinery or timber yard, the SP720 handles the cutting. The series has been on the market for decades and is continuously improved in close cooperation with our customers around the world. It is available as a stand-alone saw or as part of a larger, integrated Randek machine line together with infeed and outfeed tables, routers and more.
Randek’s crosscut saw platform: angled and inclined cuts in one machine, computer-controlled length stops, and up to three board layers per cut.
- Angled and inclined cuts in one machine. The blade swivels and tilts, so every oblique and compound cut a timber structure needs is covered. No second setup, no second machine.
- Cut up to three board layers at once, with a maximum stack height of 250 mm, for higher throughput.
- Computer-controlled length stops position each cut automatically and compensate for the cut angle, so the finished board length is always right.
- Fixation close to the blade. Retracting devices press the timber against the back fence and plungers hold it down to the table, both automatically and as close to the cutting line as possible, for consistently high accuracy.
- Graphical touch-screen HMI. The operator sees the current detail on screen, which speeds up setup and minimises production faults.
- Works with your existing software. Import complete projects directly from market-leading house and truss design software (ASCII files from all common CAD systems are supported), or design boards on the machine.
- Easy to network. A LAN/Ethernet connection lets you transfer cutting lists across your company network; storage is limited only by the hard drive.
- Flexible layout. Feed direction available left-to-right or right-to-left to suit your factory flow.
CUTS TIMBER
Every timber cut, in one saw
The SP720 series crosscuts timber for roof trusses, wall and floor elements and whole houses. The blade swivels and tilts, so angled and compound cuts are covered in one machine, up to three board layers per cut.
THE CHOICE
Two models
Choose the SP722 for angled crosscutting at a lower power and price point. Choose the SPL728 when you need the full range of inclined, compound cuts, the standard choice for roof-truss production.
COMPOUND CUTTING
SPL728
Blade swivel 0°–360°, blade incline 90°–28°, 7.5 kW saw motor.
Full compound cutting for roof trusses and complex framing.
How it works
Timber is fed along a non-driven roller conveyor by a manually activated feed roll to its position for the current cut. When the operator starts the cut, the retracting devices and plungers automatically fix and straighten the board. The under-table blade is raised pneumatically to make the cut, and the computer-controlled stops on the outfeed table set the next length. The operator follows the whole process on the touch screen.
ADD-ONS
Peripheral options
The SP720 connects to an extensive range of peripheral equipment, so the line can be configured to your production. Alongside timber pickers, outfeed stackers and pushers and label printers, two units are added directly to the saw and its benches:
Splicing press (SKARV 35)
A 35-tonne (343 kN) nail-plate splicing press on the infeed bench joins boards end to end before cutting, so timber can be spliced to any length with minimal waste. Plungers and retracting devices keep the boards aligned during pressing.
Milling machine (SPL-FVS375)
A milling head for birds-mouth and seat cuts, manually adjustable between 0 and 45° with a cut depth up to 120 mm. It works on its own or alongside the SPL728 and SP722 saws.
EXAMPLE LAYOUTS
From a stand-alone saw to a full line
The SP720 saw works on its own or grows into a complete line with feed benches, timber picker and stacking. These are example configurations; we plan the exact line with you in a pre-study.
THE SAW
Saw only
The SP720 saw unit on its own. The operator feeds and positions the timber by hand and the saw makes every angled and compound cut. The simplest way to add accurate crosscutting to a workshop.
Stand-alone saw unit
WITH BENCHES
Saw with feed benches
Add infeed and outfeed benches with a powered timber feeder, so the board is transported to each cut and the computer-controlled length stops set the length. Retracting devices and plungers fix the board at the cutting line for accuracy.

AUTOMATED LINE
Full SP728 line
A full line: a timber picker feeds boards from the pile, the saw cuts, and an outfeed stacker piles the finished timber onto a lift table automatically. The high-throughput setup for roof-truss and house production.
