Capabilities

The Mori Seiki Partner M-300 is a compact CNC machining center designed for precision metal cutting and shaping. With 400mm x 300mm x 495mm travel dimensions, a BT40 spindle running up to 6000 rpm, and 5.5 kW of power, it handles milling, drilling, and boring of small to medium components. The 30-tool magazine with 2.5-second tool change time keeps production flowing efficiently, while the 3400 kg clamping force and sturdy 315mm x 315mm table accommodate various workpiece sizes and shapes.

Industries & Uses

This machine is popular in tooling shops, small manufacturing operations, medical device production, automotive suppliers, and job shops that need reliable precision work without the footprint of larger centers. It's ideal for businesses producing prototypes, custom parts, or low-to-medium volume runs where flexibility and accuracy matter more than high-speed production.

What to Check When Buying

When evaluating a used Partner M-300 from 1990, inspect the spindle bearings for noise or play, check the ballscrew condition (worn screws cause accuracy loss), and verify the automatic tool changer functions smoothly. Request full maintenance records, spindle runout measurements, and confirmation that the control system operates properly. Look for signs of coolant leaks, worn table surfaces, and whether the machine has been regularly serviced—these factors directly impact precision and reliability.
