This pick-up machining centre allows operations in position horizontally, vertically or in any intermediate position.

It is designed to meet the requirements of machining of complex parts. Allows more operations of turning, drilling, threading, slotted notches and machining of straight or sloping faces in a single subject. It is possible to perform on the same machine so delicate as eccentric drilling operations either inclined, helical grooves, milling of cages, as well as taladrados of deep holes and also many more operations.

Equipped with a storage of tools, this machining centre is adapted for production in small, medium or large series.

In this way, "gemini" is suitable for horizontal fixing of these milling machines and for the measurement of the cutting edges in the perimeter by transmitted light. The treatment is optimized and the special procedures of software developed in Zoller also allow the measurement of cutting edges very contiguous, automatically removing the little sharp positions in the area of the plane.

To measure automatically crankshafts with internal cutting edges milling machines Zoller has also developed the apparatus measuring "aralon", four-axis CNC control and automatic measurement contact head. After the fixing of the milling of crankshafts with internal cutting edges in the portaadaptadores special, equipped with underpinning of the loading and Automatic centering, fully automatic measuring process begins. This system provides options to determine the flatness and the concentricidad and issue stepped distances. It also includes system of automatic compensation of the concentricidad, query by using push button and two positions of security used automatically by the system.

In particular, the FV 251 M model has a size of 250 x 1,120 mm table with displacement in X/Y/Z of 820/280/410 mm and a speed of 40 to 2,000 rpm spindle.
