# Makino V300

Hardware · `V300` · verification: source checked

The Makino V300 is a vertical machining center with a 800 x 450 mm table and 650 x 450 x 350 mm X, Y and Z travel. It uses a 20,000 rpm HSK-63 spindle, box way construction on all axes, and a 20-position automatic tool changer. Thermal control systems, including cooled ball screws and slideway cooling, maintain accuracy over long machining cycles.

## Safety

- Collision Safeguard crash avoidance is integrated into the Pro 6 control to help prevent spindle, workpiece and fixture interference.

## Study notes

- All axes use box way construction for vibration dampening and motion stability.
- Spindle is designed and built by Makino with an integrated spindle and drive motor.
- Spindle thermal control includes core cooling, under-race bearing lubrication, jacket cooling and an oil temperature controller.
- The oil temperature controller also cools ball screw drive systems and controls slideway surface temperature.
- Ball screws and support bearings are core cooled, and servo motor mounting brackets are thermally isolated.
- Slideway system cooling covers all axes, including thermal control of the spindle mounting surface.
- The Pro 6 eStabilizer function suppresses positioning errors caused by ambient temperature changes.
- An optional bed and column stabilizer fills the castings with thermally conductive fluid to stabilize machine geometry.
- SGI.6 motion control software offers ten operating modes.
- An optional robot load door system is available for automated cell integration.
- High accuracy laser tool setters and spindle probes for workpiece measuring are optional.
- The control is the Makino Professional 6; optional ATC capacities are 40 and 60 tools, tool-to-tool time is 4.8 s, maximum tool diameter is 80 mm and maximum tool weight is 7 kg.
