Gantry-type machining center MCG 3022 (Multifunctional 3- to 6-axis solution)

Gantry-type machining center MCG 3022 construction is formed by an upper-gantry type portal whose frame consists of two sets of side walls and a base. The side walls and the rotary table base or a fixed table are mounted on adjustable wedges and are fastened to the concrete foundation by means of anchoring bolts. The cross rail moves in the longitudinal direction (X-axis) along the upper sides of the side walls. Inside the cross rail, a cross slide with a sliding ram (the so called box-in-box system) is moving in the transversal direction (Y-axis). The sliding ram is moving in the vertical direction (Z-axis) and can be fitted with various types of heads with electro-spindles, fixed electro-spindle or with a turning adapter.

The movements of all wholes in the X, Y, Z axes are ensured by means of a linear guideway with preloaded zero-backlash rolling units. Their dimensioning and location allows not only for high load of all movable wholes while maintaining high dimensional accuracy and surface finish quality of a workpiece even at interrupted cut, but also the machine long service life. The operational movements of the cross rail and the cross slide are performed by an AC regulating motor with digital control via rotating ball screw with a ball nut. The operational movements of the sliding ram are performed by four AC regulating motors with digital control. On the left as well as on the right side of the cross rail, on the upper side of the side walls, there are gear racks located. A pair of pinions is engaged into each rack. Each pinion is driven by a motor with its own planetary gearbox. Measurement of positions in X, Y, Z axes is performed directly by means of absolute linear measuring units.

The ZPS MCG3022i machining centre is a high-performance machine primarily determined for machining of heavy, large-sized, spatially and technologically complicated workpieces made of steel, grey iron and light metal alloys. The centre enables milling, drilling, reaming, thread cutting as well as turning operations, such as turning of outer and inner surfaces, face turning, etc. The machine functions are directed by a CNC control system which enables the machining of the spatially complicated shapes when the tool follows the path resulting from the 3D CAD program output
