The Island Concept in Manufacturing

Tajmac-USA offers the Penta TMZ 518, a 5-spindle automatic lathe with an island concept that provides the machine as part of a bundle. This design creates a single-source supplier point of contact for all these components.

The included bar loader was designed and developed by Cucchi BLT, another member of the Tajmac Group. The enclosed loader has the capacity to run five 12' long bars up to 18 mm in diameter. Underneath the bar loader, the machine houses a variety of accessories. The high-pressure system is nested underneath the loader, providing plenty of pressure to clear away chips. The integrated chiller unit is used to cool the oil in the machine and the electrical cabinet underneath the work area. A built-in side conveyor and magnetic separator system help remove big and small chips.

This CNC multi-spindle is suited for machining medium to complex parts and can achieve fast cycle times due to its ability to rotate the drum from station to station more swiftly than a 6-spindle, the company reported. The drum indexing time is 0.4 seconds on the Penta. "The innovative design was developed with the desire to keep the Penta model at a price point that competes with the cost of five Swiss machines while requiring a fraction of the space. The Penta can offer these benefits while maintaining the fast cycle times that the multi-spindle platform provides," said a company spokesperson.

The Penta uses standard, off-the-shelf drives and FANUC control capable of handling up to 31 axes. This control fits the 5-spindle configuration, which only requires 25 axes. This FANUC control makes the machine and its components more familiar to the U.S. customer base, providing an easier-to-understand platform for operators and maintenance personnel.
