The MVR-Hx series was developed on the concept of a machine that is easy to use without thermal displacement for users who pursue high precision and high efficiency. It is equipped with thorough thermal countermeasures, such as an internal spindle cooling system that suppresses thermal expansion of the spindle and the main structure that is less susceptible to environmental temperature changes. It can also be used for dies, molds, or other machining that require high surface quality to general parts machining and for all types of materials from light to heavy cutting.
The internal spindle cooling system that cools the spindle from the inside comes standard. The tooltip position can be stabilized even at high speed of 8,000 revolutions per minute, and the step between tools during finish machining is now reduced to less than 3.5 μm. When heavy-duty cutting at 4,000 revolutions per minute, the gear-driven spindle enables machining at a maximum torque of 3,430 N·m, as the main structure made of cast metal enhances the rigidity for stable machining even at high torque. The rapid traverse speed is 35m/min for the Y-axis and 20m/min for the Z-axis.
Nidec adopted a thermostabilizer column filled with a temperature control medium, heat insulation measures for the crossrail, optimal placement of scales for positioning each axis, and a spatial error correction function to eliminate the effects of heat and aging on machining accuracy. These technologies accurately grasp the position of the machine, resulting in a higher level of high-precision machining for users.
Nidec incorporated a more comprehensive operating range for the operation panel to allow operation close to the machining point and the newly developed operation support function, NidecNavi, to enhance operator efficiency. Nidec’s IoT platform, DIASCOPE provides quick and reliable support. A wide variety of package options enable customization according to each customer’s processing objectives.
