Extruded polystyrene - thermal insulation extruded polystyrene (XPS) has a closed cell structure and is strong with high mechanical performance. It has a wide variety of applications. It can be used for the insulation of buildings, roofs and concrete floors, crafts, model building, architectural models, and structural insulated panel building systems.
To surface the XPS, an array of saw blades is still widely used. Saw blades are made with welded carbide tips reheated at high temperatures and are easy to wear out. To replace a saw blade, the whole cutterhead has to be removed from the machine. Dismantling and setup take a long time. The carbide tips on the saw blade hammer board direct and often scoop off materials with the bad surface. Sheartak designed the spiral cutterhead with carbide inserts angled and seated along the helical grooves. The carbide inserts slice materials off at a part of 15mm. This leaves a better quality surface with no tear-out. The indexable carbide inserts have four cutting edges and stay sharp as 12 times long as the welded saw blades. Simply loosen the inserts, turn a quarter circle, and tighten the screws. The setup is super easy. This revolutionary upgrade increases productivity.
This spiral cutterhead is made for an XPS board extruding line. One is for top surfacing, the other is for bottom surfacing.
