Hanna – Blade-plate reamers, flange fittings

Hanna reamers are essential in finishing operations which require very tight dimensional tolerances and excellent surfaces. Normally Hanna tools are designed and manufactured to meet the individual needs of customers, analysing and developing solutions that create projects that take into account all the necessary details: geometrical specifications, dimensional tolerances, presence or absence of internal lubrication, machines and mandrels used and required productivity.

We can state that the greatest resource of Hanna is the know-how accumulated since 1942 through the development of applications designed to make each type of component. With this type of experience Hanna is able to achieve efficient and competitive solutions for the production of components related to the automotive, aerospace, energy industries, and, more generally, any precision mechanical production.

The principle which is the basis of Hanna boring systems is the separation between the cutting component (blade) and drive plates, which in the traditional conception are an integral part of the reamer. The adjustable blade is fixed to the tool body by means of a bracket and a screw (mechanical fixing). The adjustment is performed by two screws and wedges. The plates, positioned radially, provide support to the machining forces and guarantee better finish of the bored surface. The blades can be adjusted, both to obtain the desired diameter, and to define the chamfering. This is a great advantage because the conicalness is in close relationship with the final surface produced by the tool.
