          TECHNOLOGICAL RECOMMENDATIONS BY MILLING
            Effective milling is the result of:

            - technical condition of the machine
            - the proper selection of the cutter
            - the selection of a precise and rigid holder
            - rigid and securely fixation work piece
            - choice of coolant
            - machine processing strategy

            Machine

            Machine must provide the necessary power for the selected parameters of the spindle, and
            minimum radial runout. In case of doubt, reduce the machining parameters.

            End mill

            Adjust the cutter suitable for the material and dimensions; as short as possible, with a short cutting
            length and a larger diameter.

            For grooving choose cutters with a smaller number of teeth (2-3) for good chip evacuation.
            For profiling use 4-6 teeth cutters, in order to obtain a better surface quality and durability of the
            cutter.

            Holder

            For high speed milling use the hydraulic holder or with shrink fit short reach, ensuring rigidity and
            precision mounting.
            Always secure the minimum influence of the tool holder.

            Coolant

            Coolant ensures the maintenance of stable working conditions and evacuation of the cutter chips
            from the machining area. It should be clean, with a selected concentration and pressure, and served
            with carefully directed jets. Most emulsions (approx. 10%) are used or compressed air; depending
            on the material and the cutter used. Machining stainless steels, non-ferrous materials, heat-resistant
            alloys require a higher concentration of the emulsion.

            Processing technology and strategy

            To increase the life of the cutter, climb-milling is recommended. Milling of the pockets usually begins
            with a pre-drill the hole. It is also used a spiral interpolation.

            In these cases, the feed rate should be reduced to 25-50% of the values shown in the tables and
            cutting speed used as for grooving. In any case operating conditions can vary considerably.
            Therefore at the beginning of machining is recommended to reduce cutting to 50% from the tables
            selection, and then increasing to them. Deviations from the described conditions, exceeding the
            axial depth Ap and width Ae, can lead to a reduction in the cutting parameters V and fz from those
            given in the tables.n lead to a reduction in the cutting parameters V and fz from those given in the
            tables.
