Perfectly positioned pallets

The MCT 644 offers total versatility and high productivity, and each machining unit is completely automated.

A rotary handler transfers the 3R palettes from one unit to another, while individual workholding devices on each unit ensure precise positioning to within 2 microns. During the machining process, the workpieces are held in a capstan clamping ring for absolute stability.

Rigidity and modularity, precision and capability

The CU 1005 units in the MCT 644 are equipped with X and Y slides mounted on prestressed linear rails. The vertical axis of each machining unit is formed from a solid cast iron V-guide, on which a rectangular sleeve is guided along 4 rails. Table movements are performed by means of AC brushless motors with digital closed-loop control. The X, Y and Z axes are equipped with Heidenhain optical scales, with over pressure and readout to one tenth of a micron. 

The seventh station, designed for monitoring and measuring, is equipped with a Renishaw dynamic sensor, which operates as an automatic correction and tool breakage detection system. The dedicated equipment and overall design of the MCT 644 ensure maximum machining capabilities.

Each machining unit can be fitted with up to four vertical spindles, while units 5 and 6 can be equipped with vertical and horizontal spindles (2+2). This gives the MCT 644 a total of 24 spindles (28 if the measuring station is replaced by an extra machining unit) and 24 axes - 26 with the loading/unloading unit. The latter is equipped with a translatory cleaning device (cleaning, suction/ extraction, blow drying).
