Spindle Machines include integrated bar loader.

Press Release Summary:

Single-spindle, Models Deco 10a and 13a feature Robobar SBF 216, which reduces channel guide changeover time down to 15 min. With quick-change system, operators index guide block to proper size capacity and changeover is complete. System accommodates up to 150 bars in sizes from 2-16 mm. Gripper system adjusts to whatever bar size is being used in machine. All setups are integrated into machine control, facilitating programming and machine/loader operation.

Original Press Release:

Tornos "Robobars" at IMTS 2004

(Chicago, IL - September 8 - 15, 2004) Each of Tornos' single- and multispindle machine at IMTS 2004 will have a "Robobar" integrated bar loader attached to it. New at IMTS 2004, booth A-8140, is the Tornos Robobar SBF 216. The SBF 216 is designed for use on the DECO 10a and 13a single spindle automatics. Like the proven SBF 532 feeder for the larger single-spindle models, the 216 reduces channel guide changeover times down to 15 minutes.

When users need to change bar sizes in conventional bar feeders, each section of the guide channel must be manually changed. On large feeders there can be from 4 to 10 individual components with oil lines and other pieces that must be changed. With Tornos' new quick-change system, which is essentially a series of connecting guide blocks that operate as one unit, operators simply index the guide "block" to the proper size capacity and the changeover is complete. The quick-change system on the Robobar SBF 216 accommodates bar sizes ranging from 2mm to 16mm.

In addition to the productivity benefits of the quick-change system, the new Robobar features an effective bar gripper mechanism between the bar feeder and the sliding headstock. As a bar is machined, eventually the end of the bar exits the feeder. This unsupported bar section between the feeder and the headstock can negatively affect production. To provide a stable transition zone, Tornos has developed a gripper system which adjusts automatically to whatever bar size is being used in the machine.

The other key design upgrade on the new Robobar is the elimination of a separate control system on the bar feeder. Now all the Robobar setups are integrated right into the machine control, the PNC-DECO, streamlining programming time and machine/loader operation.

Like all of Tornos' Robobars, this magazine style feeder can accommodate up to 150 bars, depending on bar size. Tornos' hydrodynamic style bar feeders offer less noise and vibration because of the oil filled tube, higher rotational speeds, automatic remnant retract, and better control of part length. Further, with a Tornos-built magazine feeder, customers have the added convenience and expertise of installation and service from a single source supplier.
