Turning Center with Collet-Ready Spindle
The RS 51 MSY turning center with live tooling, C axis, Y axis and subspindle offers exceptional vibration control, thermal stability and accuracy, the company says. The turning center has a collet-ready spindle that uses a range of the company’s precision workholding devices and is designed to be hard-turning and hard-milling machine that economically produces complex hardened parts in a single setup. All RS Series models (RS 42, RS 51 and RS 65) feature the Eppinger Self Alignment (ESA) top-plate tooling system, allowing highly accurate tool positioning and directing cutting forces to the machine base, the company says.

The VL-Y from Emag is fully equipped with a Y axis (50-mm travel); a chip conveyor; a machining area extraction unit; a fluid-cooling system for spindle motor and turret; and automation equipment for loading and unloading workpieces. The machine features a recirculating workpiece storage conveyor on which “carrier prisms” deliver raw parts and collect the finish-machined components from the pick-up spindle. The pick-up station is located behind the machining area, so the operator can continue removing finish-machined components and inserting new raw parts into the carrier prisms at the front.

A Different Type Of Twin-Turret Lathe
The vertical-bed design used on this twin-turret lathe offers accuracy advantages for turning shafts.
Read MoreMulti-Spindle Features Improved Usability, Maintenance
To meet the evolving demands of high speed machining, Davenport Machine’s enhanced Davenport HP focuses on usability and maintenance. For easier interaction, the Man Machine Interface (MMI) is mounted on a waist-high pendant system that allows the operator to use the interface at the front, end or back of the machine. The sound enclosure has more windows, which increase visibility while the machine is running.
