Facing and Centering Machines HARRIS, Z8210 series

SKU: Z8210

Z8210 series facing and centering machines are mainly intended for machining faces and centering holes of shaft parts in mass and serial production – in the automotive industry, production of electric motors, reducers and gearboxes, etc. The machining is performed with the help of two opposite spindle boxes, each of which has one milling and one drilling spindle. The spindle boxes are on cross slide tables that carry out the feed movements of the spindles on two horizontal axes. The cross slide tables are powered by NC-operated servomotors and ball screws. This provides high performance in the working cycle and quick and easy re-adjustment when changing the workpiece. The parts are tightened in hydraulic vices located between the spindle boxes.

Replacing spindle tools with suitable tool holders and accessories, the machine can also perform the operations of conical countersinking, machining of holes with cylindrical countersinks, cleaning of studs, external cylindrical turning, milling and grooving, threading, etc. with special accessories and tool holders.

The automatic cycle operation is performed with CNC control.

Cycle time: It takes 90 seconds for machining with diameter φ80 mm (no loading and unloading time).

Other sizes and models can be offered too, in case of specific interest and request. This includes machines for other dimensions of the workpiece, special performance with regard to the work carried out, one-sided performance and others.
