Center of torneado-fresado MacTurn of Okuma, represented by machine Center

Multifunction machines, more precise and flexible

15/10/2004

You always have to keep in mind the savings in production costs. For that reason, Okuma promotes the new machine series Multifunction MacTurn, for the needs of current and future production of its customers. Machine Center, your representative at Spain, explains its characteristics.

MacTurn 550

The most important characteristics that warrant the MacTurn family of

Okuma are: availability, flexibility and precision. These qualities guarantee success in saving of costs of production and also increase customer satisfaction and competitiveness.

The flexibility of this torneado-fresado Center integrates technologies such as: turning, milling, drilling, drilling of deep holes, sloped, torneado-fresado, court milling thread milling eccentric, milling of polygons, carved, cut synchronized and cut simultaneously.

It is precisely its flexibility which allows to produce complete complex pieces in a cycle of much faster and recover a great potential for innovation in new buildings.

This means that you can change the material of the piece in the rough, combinarpiezas a, reduce the size of lot, reduce the available stock, etc.

To achieve these benefits, the MacTurn series features features such as the following:

Very rigid machine

broad cross-section of rigid frame
design to withstand great efforts
(up to 31 tons of weight)
modular configuration

Great power machine

powerful main spindle up to 37 kW
rigid spindle of milling up to 22 kW

Very flexible machine

multifunctional machine which controls nine-axle
Court simultaneously up to five axes
possible types of tool handle BT50, HSK-A 63, KM 63, CAPTO C 6

High productivity machine

quick tour up to 40 m/min
complete machining with subhusillo
possible Lunette in lower turret
time ATC 3.2 s (T - T)

Some examples

The range of parts that you can get to work with this team is very broad. But let's see some examples in which the Okuma MacTurn is presented as an ideal solution.
