Mitsui Seiki USA, Inc. has developed a specially-designed, 5-axis CNC vertical machining center for the production of turbine blades from forgings, castings, bar stock, or solid billets of titanium and stainless steel.  It will be officially introduced to the metalworking industry at the International Manufacturing Technology Show, September 10 – 15 in Chicago. According to the company, several customers provided design criteria, including a reasonable capital cost per part, small machine footprint, the ability to rough and finish parts in competitive cycle times, and improved part accuracy and surface finish. “In other words,” says Tom Dolan, VP of Mitsui Seiki, “the total machining center package had to be smaller, faster, more accurate than what they had been using – all at an affordable price.” After about 18 months in development, the new Vertex 550-5XB machine is the result.

Key specifications include a footprint of approximately 65 sq. ft., an X, Y, Z working envelope of 550mm x 600mm x 500mm, and rapid traverse rates in all linear axes of 48m/min.  A and B axes are represented in a rotating/tilting table. A-axis tilts from +45 to – 90 degree angles, and the B-axis features infinite positioning points. The engineering of the rotary axes offers a new, non-traditional approach, which Dolan says enhances manual and automatic load/unload operations, such as the integration of a robot and cellular manufacturing capability. Further, Mitsui Seiki has incorporated its proven spindle configuration in the new Vertex 550-5XB, ideally suited to cut hard titanium and stainless steel grades. It also is directed by the latest and most advanced Fanuc control system.

Mitsui Seiki’s tradition is to build rigid and ultra precise metal cutting and grinding machines. The Vertex 550-5XB’s geometric accuracy is carefully monitored in the tightest temperature-controlled factory environment in the world.  The machine features a cast bed which provides an ultra rigid machine structure. A unique “box in a box” design provides superior rigidity and stiffness that typically is not available in a machine of this size.  All guide way mounting surfaces are hand-scraped, achieving very high volumetric accuracies, which would be impossible to achieve on surfaces that are simply machined and /or ground. This engineering and construction concept, coupled with a newly designed machine, provides users with competitive advantages over traditional, similar purpose machines.

Makino’s PS-Series machines are the new standard in vertical machining centers for production machining, offering a reduction in cycle time, increased productivity, improved quality and minimization of capital investment. The PS-Series features a field-proven design with key technologies from several of Makino’s most reliable production machines. Its rigid construction, thermal stability and versatile spindle are ideal for a variety of applications, including automotive, aerospace, medical and other small-component manufacturing applications.

“Makino’s PS-Series comes standard with a high power 33.5 HP, high speed 14,000-rpm CAT40 spindle delivering 130 ft-lbs peak torque. No other vertical comes standard with these features,” says William Howard, Makino’s vertical machining product manager. “The PS-Series is fully equipped and ready to run all of a manufacturer’s production parts. It brings the productivity of a Makino horizontal machining center to a vertical platform at a great value.”

The PS-Series is available in two models: the PS65 and PS95. The smaller PS65 features X-, Y- and Z-axis travels of 26", 20" and 18.1", respectively; a 36.2"-by-20" table; and a maximum workload of 1,323 lbs. The larger PS95 features X-, Y- and Z-axis travels of 36.2", 20" and 18.1", respectively; a 46"-by-20" table; and a maximum workload of 1,763 lbs. Both models are standardly equipped with an easy-to-access, highly reliable, 30-tool-capacity automatic tool changer (optional 50-tool capacity available).

Based upon a traditional C frame, the PS-Series design utilizes Finite Element Analysis (FEA) techniques to perfect the massive cast iron components that offer optimal rigidity and torsional stiffness. The construction ensures the quick, efficient transfer of the cutting forces through the structure of the machine—from spindle into the column and ultimately the bed of the machine. In addition, the symmetrical nature of the casting, incorporation of core-cooled ball screws and support bearings and a closed-loop temperature compensation system secure the tightest tolerance and minimal variations during long production part runs.

Flexible Job-Shop Production Capabilities
Designed for flexibility and high productivity, the PS-Series’ standard 14,000-rpm CAT40 spindle (HSK-A63 optional) offers the ideal blend of speed, torque and horsepower for today’s competitive job shop environment. Duty rated at 33.5 HP (24.2 HP continuous) and 130 ft-lbs peak torque (70.5 ft-lbs continuous), these spindle characteristics offer efficient, highly productive machining over a wide range of materials. Large-diameter bearings, air-oil lubrication and jacket-spindle temperature control deliver long-term thermal stability and stiff, rigid, chatter-free cutting.

Created with the production environment in mind, the PS-Series chip and coolant systems enhance the productivity of the machine. Configured with flood, overhead shower, flush and through-spindle coolant as standard features, chips are efficiently and effectively removed from the cutting zone. Spiral chip augers located in the front and rear of the worktable quickly and efficiently evacuate chips and coolant from the machining zone and into a standard lift-up chip conveyor (LUCC).

The PS-Series also features Makino’s new Professional P control software configured to support a wide variety of applications in the job-shop and production environment. With a large color LCD, menu-driven, touch-sensitive screen, information is at one’s fingertips.  Configured with generous program storage (4,200-foot), 400 registerable programs, 400 tool-offset pairs and 48 pairs of work coordinate systems, the Professional P provides ample standard capabilities for production shops of all sizes.
