Automatic eight-position head UG8

The head with a horizontal axis of rotation is designed for installation, fastening and automatic indexing of cutting and auxiliary tools.

The heads are equipment nodes for lathes with various numerical control systems and are used for chuck-center work under UHL4 operating conditions according to GOST 15150.

The maximum imbalance is 20 Nm.

The maximum weight of cutting and auxiliary tools must not exceed 45 kg. When using less than eight positions, the toolholders must be installed evenly across the entire disk of the head (to reduce imbalance and wear of the moving part of the head).

The frequency of head cycles should be no more than 60 cycles per hour. Cycle is a moving from position to position
