Multitasking Technology for Turn-Mill Lathes Evolves

The concept of turn-mill on one machine has been around for quite a while. But the technology has evolved (and continues to) over time as OEMs have found new ways to optimize productivity, profitability and part quality(include CNC machine controls).

This article beings with a short video clip of a turn-mill operation in action. The author then reviews the technological development of turn-mill machines over time, from the early stages of adding backworking spindles to CNC lathes, or opposing twin spindles, to more recent machines with three turrets that include Y-axis capability. Each development was a move toward more complex part production while reducing cycle time and costs.

when to combine milling and turning 
Released in may 2008, this article features an in-depth look at some of the process considerations surrounding the application of turn-mill technology. Technologically, the article uses a Mori Seiki turn-mill machine as an example of the flexibility of the multitasking capability to machine complex parts in a single handling.

As for the application of this technology,Pfeifer Industries in Naperville, tells how the installation of turn-mill machines has helped in compete by reducing multiple operations to a single handling.One example cited is a part that the company previously produced with 3 minutes,15 seconds of turning and 4 minutes,8 seconds of milling.The part was reduced to total of 5 minutes, 20 seconds when run across the turn-mill center. Production was upped from 87 parts per day to 252 parts per day.

CAM and Turn-Mill: Making More with Less
Often a stumbling block to investing in turn-mill technology is a perceived difficulty in programming the machines. how much to optimize the multiple operation in a sequence that is most efficient is the subject of this article.
It looks at how Norriseal, a Houston, Texas, based manufacturer, overcame this concern using sophisticated software, in this case Edgecam from Planit Solutions, to confidently program its turn-mill machines. It also discusses how the company dealt with the human resource side of the equation by involving its personnel in the decision-making and implementation of new software and machines, providing the employees "buy-in" and helping ensure sucess.
