New V.P. at Okuma AmericaJim King will join Okuma America Corporation as the senior V.P. of sales.

Software Certified by Autodesk InventorGibbs and Associates’ GibbsCAM 2009 has been certified for Autodesk Inventor 2010 software under the Autodesk Inventor Certified Applications Program. Certification is granted only after a product has been thoroughly tested by internal staff at Autodesk.

While still running a few different CAM systems in the shop, this manufacturer of aerospace and oil and gas industry components has implemented what it sees as the ideal package for programming its multitasking work.

A shift in thinking has led to an overhaul of this company’s machine tools and production processes. The result has been a significant improvement in capacity that has allowed more parts to be brought in-house and more profits at the end of the day.

Designed for accuracy and flexibility, the NT6600 DCG/4000CS turn-mill center features a large Y-axis travel, a fast Z-axis rapid traverse rate and quick tool changes, the company says. With a footprint of 33.

Mori Seiki's NZ2000 T3Y3 is a multi-axis machine manufactured with three turrets with built-in milling motors and a Y-axis function. Built for mass production machining, the machine series is a solution for machining bar material, shafts, flanges and precision equipment.

Turn/Mill technology enables users to complete a workpiece in a single handling. This article looks at some of the criteria that make application of this multi-tasking productive.

The DDRT-260 rotary table is designed for operation on Mori Seiki's DuraVertical 5060 and 5080 and NV4000 DCG vertical machining centers.  It offers stable, high-efficiency four-axis machining with powerful clamping and high-precision indexing, the company says.

Mori Seiki's DuraTurn CNC lathes and DuraVertical vertical machining centers offer durability, stable machine performance, high levels of reliability and excellent cost performance, according to the company. The DuraTurn line was developed with a rigid body to minimize the effects of vibration and increase accuracy,

Mori Seiki's NL Series of CNC lathes are especially useful for medical manufacturers, particularly those specializing in the production of joint replacement components. Difficult to machine by any standard, these complex parts are usually made of titanium or stainless steel and require extreme accuracy and surface finish. The machine's milling capability allows it to meet the demands of a lean supply chain, according to the company.

• Literature features Mori Seiki’s NZ Series, which offers a maximum of three turrets and 48 tools • Includes diagrams of the front and side of the turning center, as well as specifications • Also includes a line-up of the 10 variations of the turrets and Y axes.

Mori Seiki's NT series of mill-turn centers combines a lathe with a machining center. In designing the series, the company rethought the design and construction of the multitasking machines to harness the turning ability of a lathe and the cutting ability of a machining center. The NT5400 DCG/1800S employs both DCG (driven at the center of gravity) technology and the box-in-box construction of the NH series horizontal machining centers, along with the turret with a built-in milling motor from the NL series CNC lathes.

Mori Seiki's NMV5000 DCG VMC includes direct drive motors on the B and C axes to improve the machine's precision as well as MAPPS III, the latest iteration of the company's standard setting control. MAPPS III offers improved hardware specifications, operability and shorter programming times, as well as a collision prevention function that monitors machine movements in real time. The controls also take advantage of the ease and convenience of conversational input, providing high-speed canned cycles that lead to increases in programming speed.

The NZ-S1500  has been created to machine shafts. It employs a symmetrical design in which the two turrets are aligned with the spindle, which is mounted on the vertical bed. This layout is designed to increase productivity; improve accuracy during continuous machining; and reduce the input of heat.

Mori Seiki’s NZ-S1500 is making its North American debut. Created to machine shafts, the footprint is less than half the size of previous models, measuring less than 5' in height. The machine can accommodate workpieces with a maximum machining diameter of 120 mm, and a standard machining diameter of 60~20 mm.

Mori Seiki's NT Series of integrated mill-turn centers combines a lathe with a machining center. In designing the series, the company rethought the design and construction of multitasking machines to harness the turning ability of a lathe and the cutting ability of a machining center. The series employs both DCG (driven at the center of gravity) technology and the box-in-box construction of the NH Series horizontal machining centers, along with the turret with a built-in milling motor from the NL Series CNC lathes.

Developed to provide milling capability as robust as a machining center, NL CNC lathes feature a milling motor inside the turret directly coupled to the milling tool. This design reduces tool spindle acceleration time by two-thirds and diminishes vibration and noise by one-half. Machining accuracy has been improved through increased rigidity and the measures taken to minimize the effects of heat displacement.

Mori Seiki’s MT2500SZ multi-axis turning center integrates the capabilities of both a lathe and a machining center. The machine accommodates small and complex workpieces requiring machining on all sides as well as highly accurate machining of workpieces that mainly involve turning.  The main spindle’s oil-cooled base ensures thermal stability throughout extended operation.

The NV4000 vertical machining center is said to give users the ability to contour more accurately, accelerate among positions faster and experience less residual vibration. Using a design concept called Driven at the Center of Gravity (DCG), the net driving force acts through the center of the axis. The machining center contains five ballscrews,­ two on the Y-axis, two on the Z-axis and one on the X-axis, that enable a reduction in vibration without sacrificing speed for accuracy.

The ZT1000Y, a dual process turning center with a Y axis, is a productive integrated machine that is said to meet customer demand for shortening lead time. This efficiency is especially valuable for the home electric and communication industries. Both spindles and turrets have the same capability and power.

High-pressure coolant systems are providing improved part quality, increased tool life and other benefits for this precision turning shop.
