Mitsui Seiki (USA) Inc.

The machine’s X-, Y-, and Z-axis travels are 300mm, 325mm, and 200 mm (11.8", 12.8", 7.9") respectively. A-axis rotation is +40˚ to -100˚, and the C-axis rotates a full 360˚. High-speed linear motors move the X-, Y- and Z-axes, while the rotary axes employ direct-drive motors. Rapid traverse speed for the X-, Y-, and Z-axes is 20 m/…
The machine’s capabilities include a 15 kW direct-drive motor that produces maximum wheel spindle speed of 6000 m/min. X-axis stroke of 330mm features a rapid feed rate of 5m/min, Z-axis stroke is 2150mm with 10m/min rapid feed, and maximum work spindle speed is 200 rpm.
With five axes of motion and storage for 40 tools, the machine can grind thread grooves and also machine the nut circumference, end surface, key grooves, and return tube holes in a single setup. In addition to producing large savings in manufacturing time, elimination of setup changeovers also assures exact phase alignment of thread grooves and…
The line provides positioning accuracy and repeatability of +/- 1µm. A thermal compensation system employs sensors on the machine faceplate and inside the spindle to minimize the effects of temperature changes on part accuracy and cut temperature-generated displacement by 60 percent. This system also reduces Z-axis thermal growth and deflection by…
The Mitsui Seiki J350G jig grinder offers a combination of application flexibility, accuracy and operator-friendly operation. The machine provides a very large grinding infeed stroke, with a U-axis range of -3mm to +50mm relative to the spindle center. This provides the flexibility to grind small- and large-diameter holes, as well as multiple…
Mitsui Seiki’s HPX63 II 4-axis horizontal machining center, an improved version of the company’s proven HPX63 unit, features a 70% faster rapid feed rate of 54 m/min. that produces shorter cycle times and a 14% percent reduction in shop floor footprint (now 5,554mm x 3,530mm) to maximize manufacturing facility space.
Mitsui Seiki’s new HU100-TS 100 tilt-spindle 5-axis horizontal machining center is built to handle machining of large, hard-metal workpieces that are better suited for tilt-spindle processing than trunnion table operations. The machine’s fixed table and tilting head arrangement facilitates production of heavier and larger parts and can permit use…
Mitsui Seiki says its new Vertex 100 5-axis vertical machining center is engineered to fulfill manufacturers’ demands for a compact, high-speed machine capable of high-precision milling of larger parts such as blisks for aircraft engines. The Vertex 100 can machine workpieces 1,250 mm in diameter and 850 mm tall while occupying only 3 m x 4.2 m of…
The new Mitsui Seiki PJ812 Precision Profile Center is a 3-axis CNC vertical jig mill engineered to perform high-precision contour machining and ultraprecise boring of components with critical tolerances. It is suitable for processing parts for the mold and die, optical, aerospace and medical industries.
Mitsui Seiki USA Inc. announces a new series of large, highly accurate CNC jig mills for producing mold bases, mold plates, precision hot runners, progressive and transfer dies, and other jig boring and milling applications. The fixed cross-rail, massive ram design of the J1620 and J1620X machines provides a straightness accuracy in X and Y axes…
The newest addition to Mitsui Seiki's heavy-duty series of HU100 horizontal machining centers is engineered for precision boring of large parts in energy-related industries as well as other critical applications.
