Twin Screw Barrel are the large cylindrical elements with highly accurate and precise threads on their surfaces. These are widely used in plastic industries to mix raw materials used for the manufacturing of products like pipes, sheets and foam boards.
The Profimach deep hole Drilling-Boring-Honing machines have features to allow
the precision manufacturing of barrels and twin-screws barrels.
The solid bed, the precision roller guideways used on the axis and the big system for coolant and chips filtering allow the best performance and surface finishing of these machines. The features offered by the possibility to lap or hone on the same machine allow the finishing of barrels by one set up only.

Our twin barrel drilling-boring-lapping machine has been expressly designed for the complete machining of twin screw barrels. The machine feed movements slide on precision roller bearings which provide high precision and long machine lifetime. The CNC controls all axes and facilitates the programming of billet drilling, push and pull boring and lapping operations. Main features of this special boring machine is the workpiece setup on two carriages with controlled cross feed. After finishing the first hole the machine automatically translate the barrel to machine the second one. This machine is available in different versions up to 8000 mm length and 800 mm workpiece diameter.
