With the new FZ 100 portal milling machine Zimmermann has managed to achieve 6-axis machining using the newly de­ eloped M3 ABC 3-axis milling head. This concept sets new v standards in the volume machining of aluminium, composite and model making materials as well as in the High Speed Cutting of steel and cast iron, where conventional 2-axis fork heads with A- and C-axis have long reached their limits in the 5-axis simultaneous machining. Performance: Machining four times faster is possible The machining time for typical operations such as the milling of pockets with sloping sides, for example...

The world's first 3-axis milling head: M3 ABC Up to now 2-axis fork heads with A- and C-axis have been used for 5-axes machining in portal milling machines. This method has the disadvantage that there is a pole at the zero position of the A-axis, where the C-axis of the milling head is ineffective. The C-axis cannot swivel the milling spindle when the milling spindle is in the vertical position. Even the slightest change in orientation requires large rotation of the C-axis. This leads to the following disadvantages: Considerably reduced productivity and surface finish in simultaneous machining...

Great flexibility Similar machining speeds to the M3ABC can be achieved, in certain cases, using a parallel kinematic milling head or an A-/B-head on gimbals. However, these solutions have a restricted swivel angle and thus often require subsequent machining with additional angle heads. This does not apply to the M3 ABC: It has three degrees of freedom and large swivel angles, thus offering complete flexibility in the way it is used. Surface finish Machining is performed at all times with the optimal high feedrate and always with an optimally oriented tool. For the first time in 5-axis simultaneous...

A strong portal design for perfect 6-axis machining Portal milling machines are very versatile, making them an ideal basis for the new 6-axis machining. The construction with fixed side walls and an overhead portal moving in the X-direction results in very low and constantly moved masses. Thus the machine has a consistent dynamic performance leading to excellent surface finish, even with very large com­ ponents. The large degrees of freedom in all axes are greatly enhanced by the 3-axis milling head, permitting optimal finish machining in a single set-up. Design of the side columns The side columns...
