Integrated, Automated Hard Turning and Grinding

These vertical turning machines and turning and grinding centers from EMAG ensure accurate component geometry while also guaranteeing low component costs when manufacturing small chuck parts or larger components.

High component quality with low production costs is required in many applications involving machining chucked parts. In Booth N-6846 at IMTS 2012, EMAG LLC (Farmington Hills, MI) will show solutions that combine these requirements. One of the highlights will be the introduction of the brand new VL 2 P, a vertical pick-up turning machine which operates using pendulum technology.

Whether you want to manufacture small chuck parts or larger components, the machining processes must ensure accurate component geometry while also guaranteeing low component costs. These requirements and more are met with the VL 2 P and VL 5i vertical turning machines, as well as the VSC 400 DDS turning and grinding center.

The advance in productivity comes through the integrated pick-up automation and a machine body made of polymer concrete as well as the vertical design which ensures perfect chip flow conditions.

Workpieces up to 100 mm diameter can be machined in full on the innovative VL 2 P, a two-spindle turning machine. The machine uses two spindles because, while one workpiece is being machined, the second spindle automatically loads itself using the pick-up method. This means that the next raw part is immediately ready for machining, resulting in extremely short chip-to-chip times that improves efficiency and eliminates idle times.

The VL 2 P also has an incredibly small footprint due to its compact design, which helps decrease the chip-to-chip times.

The VL 5i turning machine is a universal solution for production companies that can completely machine workpieces of up to 250 mm diameter in a single clamping operation. In addition to the powerful pick-up working spindle with a rating of 28 kW and a torque of 300 Nm, the machine also has an automation system with a revolving belt which contains drag frames.

The machine could be described as being self-automated, which means that new raw parts can be positioned and finished parts removed at any time. Another strength of the VL 5i is its short idle times because the distance between the loading and the machining positions is just 550 mm.

The VSC 400 DDS vertical grinding and turning center combines a range of processes and guarantees extremely cost-effective processes in the production of complex chuck parts with a diameter of up to 400 mm. Within a single clamping operation, the center can complete scroll-free turning and hard turning as well as subsequent grinding processes.

Grinding is only used where quality and process reliability demands it. The center can also be fitted with drilling tools or hardening modules to suit the required machining task. Even measuring tasks can be integrated. www.emag.com
