Controlling of the Machine
- all functions of the machine, except for clamping and unclamping, are controlled via the control panel, which consists of a keyboard, a switch panel and an LCD monitor
- the clamping and unclampig of tools is controlled by the key on the wall inside the operator platform
- the control panel is supplemented by a portable control panel (handwheel), which duplicates some of the basic functions of the machine control
- the control panel is situated on the operator platform, which is an integral part od the group column/headstock
- the control system allows manual, semiautomatic and fully automatic modes
- the standard operator’s site is on the operator platform
- an alternate operator’s site is outside the operator platform and is usable only in the fully automatic mode
- the standard communication interface allows a connection with the Ethernet for easy administration and distribution of technological programs, machine operation monitoring, diagnostics or servicing of the control system, etc.
Machine design can be customized.
