Mori Seiki's NV5000 VMC was designed to increase speed and efficiency both in and out of the cut. Its X, Y, and Z-axis travels are 31.520.120.1 in.
Speed — both in and out of the cut — is key to the performance of the new NV5000 vertical machining center from Mori Seiki, Irvine, Tex. The machine design, says the company, is efficient in operations, size, and maintenance. The resulting machine, therefore, keeps chip-to-chip times to just 2.6 sec, while handling a variety of applications.
Mori Seiki uses a short, light spindle with Direct Drive Spindle (DDS) gearless technology that brings out its full power at all speeds. The 12,000-rpm spindle accelerates to full speed in 0.97 sec. As for noncutting time, the machine is equipped with an automatic toolchanger that exchanges tools with the 30-tool magazine in just 1 sec. Rapid rates in all axes are 1,654-ipm, further increasing speed. As an additional capacity, these quick spindle and feed speeds let the system perform fast and accurate synchronized tapping.
Also for efficient maintenance, Mori Seiki decreased the number of parts making up the system, as well as the number of disposable parts. The linear guides use sealed bearings that are permanently lubricated, thereby eliminating the expense and hassle of way oil. The electrical cabinet is only 12-in. deep, making it easy to reach components. Power consumption is also minimized by using high-efficiency servomotors and automatic power-saving features. For rugged and reliable performance, the machine's interface is the MAPPS operator panel with no moving parts. Options for MAPPS, such as CAPS-NET for remote process logging and CAPS-DSN for program transfer, connect to an ethernet network.
