Monitizer | Discover’s alarm functions enhance production control and support inexperienced users. If an issue needs attention, the system contacts different groups of people in different waves, sequentially, depending on how the problem develops, and whether the first alerted group reacts. “If a machine runs outside its ‘green’ operating zone, the supervisor gets alerted,” according to Grede St. Cloud foundry general manager Bart Hoemann.

“Customer education is important because customers understand best the final part application,” according to Eagle Alloy CTO Nic Tarzwell. “The more they understand the capabilities of the foundry process and materials, the better we can help them maximize their casting design, take full advantage of the casting process and reduce unnecessary costs.”

Forward-Thinking Finishing

Jan. 22, 2010
A large-scale steel-ball burnishing design advances vibratory finishing designs.

The HR-100-LR Spiratron vibratory finishing machine combines proven structural design methods, for uninterrupted production, and the triple-drive system, for long service life.

In a down economy the best defense is to be innovative and forward thinking, and now Hammond Roto-Finish has manufactured a 100-ft3 steel ball burnishing machine. The HR-100-LR Spiratron is a vibratory finishing machine like none built before it. A customer- and process-specific requirement dictated that the machine have a large capacity range. The design blends older structural methods and incorporates the triple-drive system proven by past Hammond Roto-Finish machines. These features allow for extremely long service life for the drives, and un-interrupted production for the machine operators.

The HR-100-LR Spiratron features:

  • A process channel measuring 23 in. wide 32 in. deep;
  • True spiral incline tube weldment;
  • Batch or in-and-out processing capability.

The design is ideal for foundry operations, for cleaning large parts unsuited to past vibratory burnishing machine designs.
