The automatic load table, the exit bar separation, and the unloading units can be very sophisticated and, therefore, expensive. But because of the high production rate and the benefits of automation, the higher cost can easily be justified. Layer saws are especially popular in the oil industry where large quantities of tubing must be cut to then be welded together for oil pipelines. Forging shops are also cutting large quantities of solid bar stock, but are usually shorter cuts, less than 1m long. The saw usually has a horizontal and vertical clamp unit on both sides of the blade to allow the bars to separate before

the blade is retracted. Another common features of layer saws are dual hydraulically actuated scrap tipping tables (arranged on both sides of the saw blade) used for trim cut and crop cuts. Another way to increase tool life is a retracting spindle mechanism, which backs off the blade from the cut surface after the cut, before the blade is retracted, to avoid damage to the teeth. In conclusion, because of the intricacies in advanced sawing systems, projects are most successful when the machine designer, the machine builder, the blade manufacturer, and the machine operator work closely together.
