This Mori Seiki Partner M300 A-1 is a used machining center — sometimes referred to as a CNC machining centre or vertical machining centre — a type of machine tool designed to perform milling, drilling, boring, and tapping operations on metal and other materials under computer numerical control. Mori Seiki is a well-established Japanese manufacturer of precision machine tools, long recognised across the metalworking, aerospace, automotive, and general engineering industries for producing high-quality CNC turning and machining equipment. This example was manufactured in 1990 and is currently located in Germany.
The machine is controlled by a Fanuc O-M CNC system and offers axis travels of 400 mm in X, 300 mm in Y, and 495 mm in Z. The distance between the spindle centre and the pallet table ranges from 25 to 325 mm along the Y-axis, while the spindle nose-to-table distance spans 125 to 620 mm along the Z-axis. Rapid traverse is rated at 24 m/min, and the feed rate reaches up to 5 m/min. Axis motion is delivered via Fanuc AC servo drives — Model 5 units on the X and Y axes and a Model 10 on the Z-axis — with a 36 mm diameter ball screw spindle providing precise linear motion.
The main spindle covers a speed range of 100 to 6,000 rpm, powered by an AC motor rated at 5.5 kW, and accepts tooling via a BT 40 taper interface. The integrated pallet system uses a 315 x 315 mm pallet with an indexing angle of 7.5 degrees, an indexing accuracy of ±2 seconds of arc, and a repeatability of ±1 second of arc. The pallet clamping force is 3,400 kg, and the maximum supported workpiece weight is 150 kg.
An automatic tool changer is fitted with a 30-position magazine. Tool change time is 2.5 seconds, with a collet clamping time of 7 seconds. The changer accommodates tools up to 110 mm in diameter, 250 mm in length, and 8 kg in weight, giving the machine considerable flexibility for complex multi-operation workpieces.
Among the special accessories included are a work completion indicator with signal lamp, an operating hours counter, tool life monitoring, a coolant system, and work area lighting. The machine weighs approximately 4,500 kg and has a footprint of 1,900 x 2,300 mm.
