Sandvik Coromant is planning to highlight recent innovations developed with its technology partner Mitis at JEC Europe, which is due to take place on 10–12 March 2015. In addition, visitors to the show on 10 March are invited to attend a free presentation on the subject of vibration-assisted drilling in the Agora area at 11:00.

Vibration-assisted drilling has been created to help overcome the challenges of drilling stack material. It is a process that offers several advantages when performing CNC drilling and countersinking on carbon-fibre/aluminium composite stack materials typically used for aerospace frames and associated parts.

To highlight the benefits, the presentation will show a conventional drilling and countersinking process, followed by another drilling and countersinking operation using pecking cycles. Finally, drilling and countersinking using the Mitis vibrator system and Sandvik Coromant tooling will demonstrate clear advantages over the first two processes, which include better chip control, cycle time and quality. 

JEC Europe will be held at Porte de Versailles in Paris. Opening hours are 09:00 to 18:00 and Sandvik Coromant will be located in Smart Hub Pavilion 7.3 Q42.

More information on vibration-assisted drilling

  • The principle of vibration-assisted drilling is to fractionate chips. In simple terms, this is facilitated by creating an oscillating movement of the drilling process.
  • Using the Mitis system, these axial, low-frequency oscillations (1.5 per rotation) are adjustable in amplitude according to the application conditions and material using a simple ring adjustment. 
  • The upshot is a process offering optimised chip breaking when drilling composite stack materials. Furthermore, cycle times are reduced as there is no pecking, and power consumption is low. The process can also be performed with no or greatly reduced lubricant.
  • Trials have demonstrated that vibration-assisted drilling can meet the specification requested by aerospace OEMs in terms of surface finish, diameter, exit burr and process capability (CP/CPK).
  • The easy-to-use system, which offers spindle speeds up to 9,000rev/min, offers standard mounting shanks such as Capto HSK and ISO, and is adaptable to all machines without modifications.
