 TECHNICAL SPECIFICATIONS
Section capacity The Razer is able to process section sizes laying flat with a cross section of 35mm x 75mm (1½" x 3") up to 350mm x 100mm (4" x 14") and a feed length of minimum 850mm (33") and maximum 6m (20') in length. Members stacked on top of one another and side by side can be processed with the Razer, providing the combined cross sectional area of the pieces does not exceed the process section capacity indicated above. Some types of cuts and combination of cuts may not be supported when using the multiple member cutting feature. Accuracy The length accuracy of cut pieces on a linear saw is very dependent on the quality of the timber. Sweep and bow effects on the timber can alter the accuracy of the finished component. Straight to straight cuts are generally more accurate than bevelled and mitred cuts. Build up on the rollers from residue on the timber can also affect the accuracy and in some cases regular cleaning of the rollers is required. Inherent design features of the razer minimise these effects on accuracy by having separate encoder feedback devices on the in feed and out feed of the machine and having a very small cutting chamber between the in feed and out feed rollers. An intelligent and automated length calibration system continuously makes calculations between the position of the feed rollers and what the encoders are reading on the in feed and out feed feeder rolls, and triggers received between fixed laser sensors situated on the in feed system. The conclusions from these readings determine the scaling factors that determine the lengths of the pieces.As an indication, the following are the accuracies we have found at most of our sites in actual production. Length accuracy
Angle and bevel Accuracy ± 0.5 ° Productivity The productivity from the Razer machine is primarily dependent on the ability to keep the saw continuously fed with timber. This in turn depends on the levels of automation on the in feed and out feed of the saw and how many operators are involved in the process. Other factors affecting the productivity of the system are the type (complexity) of cuts, average lengths of pieces and the size of the timber being processed.The following is a guide on the productivity expected from various systems over a one hour period based on the continuous supply of materials and manufacture of a roof truss comprising of two top cords, a bottom cord and seven webs with an approximate span of 6m (20'). The number of personnel required to achieve the numbers is also supplied as a guide.
