Used CNC Lathe 16K20 – EL-STER Modernized, ETA17 CNC 10T Control – Inowrocław

Used CNC Lathe 16K20 – ETA17 CNC 10T Control (EL-STER Toruń Modernization)

We offer for sale a heavy, extremely rigid CNC lathe built on the legendary cast-iron bed of the 16K20 lathe. The machine has undergone a complete overhaul and control-system modernization carried out by the specialized company Z.P.H.U. EL-STER Toruń (modernization plate no. 12ETA012008, CE marking).

The lathe is equipped with a dedicated ETA17 CNC 10T control system with a full operator panel, function keys and CRT monitor, together with a newly arranged electrical cabinet with a frequency inverter (VFD). This provides stepless spindle speed regulation, high torque at low speeds and quiet, energy-efficient operation of the main drive.

This is an ideal machine for efficient roughing and finishing of housings, shafts and sleeves in metalworking shops, tool rooms and in unit or medium-batch production.
