Condition: new, Stromab Matrix F Automatic Fully Programmable Cross Cutting & Notching Machine A heavy duty optimising upstroke crosscut and notching machine, designed for programmable and repetitive cutting and notching from standard and / or random lengths of timber. The saw unit has a pneumatic upstroke action with variable speed control, The notching unit is independent of the saw and therefore allows for programming of the saw or notching either as separate program's or as one single job. The pusher / feed is fitted with a heavy duty rack and pinion drive feeding system for fast positioning giving a high level of repeat cutting accuracy. The saw unit and clamping area is totally enclosed by a clear hinged electrically interlocked hood that while giving the operator a clear view of the cutting area still gives complete protection. The infeed and outfeed tables are of all steel construction meaning even heavy sections or packs of timber can be processed. For additional operator safety the rear of the pusher system is guarded, while there is a full length safety pull cord on the front infeed table. Programming and entering of cutting lists is very simple through a colour touch screen controller with graphic representation of the cut pieces. The machine offers full optimisation and also has the added optional facilities of defect cutting and remote programming from PC or laptop with transfer vis USB key or network. Additional options also include - extended outfeed table and label printing. To date we have supplied over 250 Matrix saws in to the UK, with a number of customers installing several machines.
