The long-selling brand that is beloved and evolving Vertical Machining Centers MB-V Ⅱ series

The innovation that accepts temperature changes

High accuracy can be achieved in normal factory environments

The machining accuracy of workpieces changes significantly due to the ambient temperature around the machine, heat generated by the machine, and heat generated in machining. The Thermo-Friendly Concept is a unique concept to “accept” such temperature changes so that high accuracy can be achieved in normal factory environments with no special measures taken by the user.

MB-46V Ⅱ
Thermo-Friendly Concept

Achievement of both high accuracy and high productivity with emissions reduction and energy saving

Green-Smart Machine

High accuracy, high productivity + Decarbonization, energy saving

We chose the name “Green-Smart Machine” for our machine tool that achieves high accuracy and reduced energy consumption autonomously and realizes high productivity. With Green-Smart Machines, we will contribute to the solution of social issues faced by the global manufacturing industry, together with our customers.

High accuracy

Outstanding dimensional stability enables stable machining of high-accuracy parts
and stable operation over long hours

In the MB-V Ⅱ series, the Thermo-Friendly Concept has been further evolved and dimensional stability has been improved. By further enhancing the machine's structural design, MB-46V Ⅱ offers an improved dimensional changeover time in a typical factory environment, from 8μm (conventional machine) to 5μm, an improvement of 38% (compared to conventional machines), allowing it to maintain high accuracy with greater stability. Since there is no need maintain a constant ambient temperature, factory equipment costs and power consumption can be significantly reduced.

Cutting time and non-cutting time are shortened to increase productivity and reduce power consumption

Cutting time and non-cutting time are reduced to improve productivity and lower power consumption

The machining time can be shortened with an increase in the acceleration of the feed axis to reduce the cutting time, as well as with an increase in the rapid traverse and the reduction of the time for tool changes and other actions. The reduction of the machining time leads to an increase in productivity over the same amount of time and enables the saved time to be used for other operations. It also leads to the reduction of the power used for machining.
