Gemac Hydraulics, a manufacturer of hydraulic adapters based in Stanwell Moor, UK, has standardised on Iemca short bar magazines supplied by 1st Machine Tool Accessories (MTA) for feeding hexagonal mild steel stock into its turning machines.

Giuseppe Costanza, Gemac’s second-generation machine shop manager, explained that the Italian-built all-electric bar feeders, two of which have been delivered to the company, have servomotor-controlled pulse-push functionality, which enables rapid alignment and feedthrough.

He said that, after setting the bar size on the bar size selector, the guide channel automatically aligns the centre of the stock with the centre of the spindle. During this time, the spindle is programmed to rotate at 40–50rev/min, which gives the bar a chance to line up properly.

One of the Iemca magazines, a KID 80, was installed in 2011 as part of an Eagle 100 CNC turning cell supplied by Dugard. The other magazine, a VIP 70 CNC, was retrofitted in 2011 by 1st MTA to a Dugard Eagle 200 HT lathe that had been supplied the previous year without a bar feeder.

Key benefits of product application

  • According to Salvatore Costanza, Gemac’s owner and managing director, a major benefit of using Iemca equipment is that the alignment of hex bar with a lathe’s chuck jaws takes less time than with alternative magazines, so bar change is faster and the lathe resumes production sooner.
  • He added that the magazines are quieter in operation than other bar feeders as there is less vibration, leading to better machining accuracy and extended tool life.
  • The short bar magazines are compact, which is important to Gemac as space is limited in the factory.
  • The Iemcas are claimed to reliably and consistently feed hex bar, as well as round bar, so Gemac’s lathe can be left to continue running unattended.
