Makino A81


Machine Overview

Horizontal machining centers with Flexible Machining Center with 8 plate, designed for high-volume machining of cast-iron and light-alloy parts of automobiles, construction machinery, agricultural equipment and other machines.

Spindle:-

The spindle accelerates quickly to its top speed of 10,000 minˉ¹ in just 2.4 sec. Moreover, because it facilitates rigid tapping at 2,500 min-1, it is effective in shortening machining times for large-volume parts .
