Retrofit boring machine

The second life of a boring machine

Client: Erga-Novaglass


The Erga-Novaglass company owned an old milling-boring machine in its workshop SKODA WH160, but with mechanics in excellent condition. The five analog servo drives were not efficient and required ongoing manual maintenance.

The programs produced by the CAM in the office arrived on the machine only via floppy disk.


ISAC offered a Compact CNC, comfortably housed in the electrical panel. The CNC incorporates the digital interface (Emerson SLM) for the axes to be moved, so the drives have been replaced with new digitally connected products.

The CNC also shares some folders on the Ethernet network so that programs can be downloaded directly from the office. It also publishes all production information to external supervision programs to check the productivity of the machine over time.

The PLC logic required adjustments to adapt to the original electrical panel, made in a few hours and verified first on the simulator, then on the machine.

Capabilities exploited

  • Conversational programming
  • Machining canned cycles
  • Parametric programming
  • Digital axis interface
  • Ethernet interface of the CNC


  • Reduced machine positioning times
  • Necessity of reduced drive maintenance to a minimum.
  • Times of machine stop practically canceled.
  • Quality of workmanship constant in time.
  • CAM programs imported into the machine directly from the Ethernet network.
