LNC express Upgrade for LANG milling machines

A performance extension to the high-resolution 4 axes servo and stepper motor controller LNC express sor your existing Impala 400. The new control equipment is a 4-axis servo and stepper motor control in the switch cabinet housing. It offers 32 digital inputs and outputs as well as encoder evaluation in all axes. A user-friendly, clear and logically structured touch control panel with "Windows 10" user interface, a manual control unit with hand-wheel encoder and jog mode function provide the user with considerably more convenience. This intuitive user guidance helps to lower manufacturing costs, shorten throughput times and thus increase profitability.

A further plus is the complete safety concept with speed monitoring, standstill monitoring and spindle standstill monitoring. The EMERGENCY STOP button on the operating panel and manual control unit protect the machine and its components from damage, as well as the operator himself.

The spindle speed potentiometer (with ±50 override) can be used to set the spindle speed within the specified limits. Further features are the key switch, release button, spray button, tool changer and the manual control unit.

LNC express makes it possible

  • higher Speed
  • better acceleration
  • more flexibility and higher comfort when operating the machine
