for the application and their geometries are adapted to the diameters of the pipes. The particular challenge here is that deburring takes place very soon after welding, so the cutting inserts are usually exposed to the still very high temperatures in the weld seam. Special cutting edge geometries and carbide grades are therefore used here.
Large-diameter pipes for pipeline construc- tion, in particular, require machining at the pipe ends to enable them to be welded together. The accuracy requirements are achieved using turning processes, for which Boehlerit supplies complete tool systems consisting of face plates, spring-loaded tool slides, cassette holders, copying rollers
and various spindles for adjustment. For cassettes and indexable inserts, there is an extensive standard program from the catalog.
Synergy effects
Innovations for tube production mainly take place in the area of cutting materials and tool concepts. The materials to be machined in this segment are mainly high- strength special steels which withstand the high forces from inside and outside. The range of materials usually extends from
X 50 to today’s X 100 plates. Corrosion-re- sistant steels are increasingly being used. The fact that the cutting material specialists from Upper Styria are also synergistically applying their know-how in general machin- ing technologies here is demonstrated, for

example, by the use of wear-resistant coat- ings and geometries for stainless steels. This ensures improved chip flow due to a low tendency to stick and thus considerably increases tool life.
The basic concept of modular tool systems for sheet metal edge processing also origi- nates from other processing fields, such as crankshaft production. There, comparable tool systems are used, which allow a base body to be flexibly equipped with milling cassettes and indexable inserts. With basic bodies, different cassettes and the com- prehensive portfolio of indexable inserts, all profiles can thus be covered. Specifi- cally selected insert designs and system solutions ensure optimum chip and heat removal during dry machining of a wide range of material qualities.
Boehlerit’s tool systems can also be found in applications ranging from general plant engineering and shipbuilding to the milling of slabs in steel mills.
Boehlerit offers in unique product diversity, the complete machining solutions in the entire process of pipe manu- facturing of all dimen- sions.
