Roughing and finishing needs no head
change
For press tool and mould and die manufacture, a travelling gantry machining centre with a new five-axis milling head eliminates the need for head-changing to complete roughing and finishing.
For press tool and mould and die manufacture, Forest - Line introduced the Easymill travelling gantry machining centre with a new five-axis milling head that eliminates the need for head-changing Dominique Werbrouck, general manager of Forest-Line said: "Changing the heads and the automatic attachment of the heads are now banned, Now, with one five-axis head, you can do the roughing operation with a high metal removal rate, and continue on with the finishing operation, without wasting time between both operations." In the new five-axis head, there are two machine spindles, one for roughing and one for finishing

When roughing is finished, the roughing spindle returns the tool to the tool magazine and then the fifth axis rotates 90 to present the finishing spindle which, in turn picks up a tool from the tool magazine and commences finishing.
degrees.
The A and C rotary axes of the 5-axis head can operate in continuous path or positioning mode.
Drive is from torque motors having acceleration up to 700 deg/s2 and rotation up to 35 rev/min.
The head is able to machine tapers and undercuts in press tools and dies.
Forest-Line says that toolpath simulation to avoid machine:work collisions and the reliability of the machining process were taken into account during the development of the five-axis head.
From a process simulation point of view, only one model of the head is necessary.
Also, when the part program has been finalised for roughing, risk of collisions is minimised as the model is the same.
The Easymill has axis movements of 6000mm, 3200mm and 1500mm in X, Y and Z respectively.
