Cold rolling

The technique of rolling consists in machining a workpiece by chipless deformation and without heating.

The method

Attestation Qualité EN9100 et ISO9001
Special machines similar to rotating presses(multi-ton thrust) are used. Tools are placed on these machines referred to as wheels and are like large screws which are coming reproduce their profile on the workpiece. Thus profile + not + diameter, defines a rolling dies set.

The advantages

Industrial technology of cold rolling has many advantages compared to other modes of production, in particular better mechanical strength, better breaking strength and excellent surface finish. The material fibers are not cut but deformed, thereby increasing their resistance.

Diameter before rolling

Before rolling, diameters must be precisely defined because we machine without removing metal. Always ask us before an order, we will send you a drawing with the diameters and the tolerances.
