MVR・Gχ

Gantry Type Bridge Mill MVR・Gχ Series

Features and Technology

Thermal Effect Shut Out Structure

  • ■ Internal Spindle Cooling System

    The MVR・Gχ series now has an internal cooling facility as standard in its spindle. In addition to the conventional external cylinder cooling, cooling the spindle from inside helps reduce extension of spindle at high rotation speeds.

  • ■ Thermo Stabilizer Column

    The MVR・Gχ series uses a robust design for its machine structures to prevent thermal deformation. In addition to the conventional thermal symmetric design Thermo Stabilizer Column is equipped as standard.
    This ensures high squareness and hole pitch accuracy minimize by environmental changes.

Note)
Robust design: A structural design having strong resistance to external changes.
Thermo Stabilizer Column: A column that utilizes the technologies used in high-precision machines to suppress thermal effects.
Thermal Effect Shut Out Structure

Save space

1) Gantry structure saves space even in the case of machining long workpiece.
Note) The fractional shortening of lengthening direction against table type machine would be changed by x-axis stroke.
2) The floor plate of Gantry type has much capabilities for the workpiece of heavy weight and/or unbalanced weight which would be difficult by the moving table type.
Save space

Note) The fractional shortening of lengthening direction against table type machine would be changed by x-axis stroke.

Factory Friendly Concept

Machines are designed with our newly propose “Factory Friendly Concept”, to be operator and environmentally friendly.

  • Wall-less structure enables operators to easily set up work.
  • Maintenance related equipment and devices are located in an area for operators or maintenance members to allow easy access to them.
  • A LED light is incorporated for energy savings.
  • Reduction of oil and air consumption
