CNC Universal Processing Centres  Manufacturers, Traders, Suppliers

The NILES-SIMMONS CNC Turning and Milling Centres enable you to manage efficient, flexible, high-precision, and operator-friendly complete machining of large size and rotationally symmetrical work pieces in one setup.
The C-series ranges between sizes N20 MC through N60 MC and can be configured as single slide or multi slide machines.
Thanks to the modular building-block system, a variety of machining units
can be added to offer utmost flexibility. Based on the C-series lathes,
efficiency of your process can be enhanced and throughput times
reduced.
Your benefits at a glance:

• Utmost flexibility thanks to modular building block concept

• Multi slide concepts
• Interchangeable NC-axis
• (D‘Andrea-tools, NC-drilling heads)
• Boring bar changer
