In 1928, the company manufactured measuring instruments,
including block gauges and micrometers. Mitsui Seiki's
quest for "precision" had begun.
In 1935, the company developed our first medium sized
“#4” Jig Boring machine to Japan’s delight. For many
years the country wanted their own jig boring technology
rather than importing it. They referred to it as Japan’s
first “mother” machine because it was primarily used by
other machine tool builders to make their critical
precision components. It helped spark a fledgling
machine tool industry in Japan. Since then, jig boring
machines have become synonymous with the label “mother
machines” worldwide.
Currently, Mitsui Seiki offers a lineup of machines
extending from jig boring machines, jig grinders,
horizontal and vertical machining centers, to 5-axis
machining centers and screw grinders that support the
world’s leading industries.
A Mitsui Seiki machine is created with a combination of
highly advanced design, engineering, processing,
assembling and measuring skills. In addition, an optimal
factory environment that takes into consideration
factors such as temperature is essential. Our dexterous
skills handed down over the last 70 years, and our
factory environment, allow Mitsui Seiki to create these
extraordinary machines.
Mitsui Seiki's Machine Tools Division moved from Tokyo's
Ota Ward to Kawajima Town in Saitama Prefecture in
October 2001.
In the history of Mitsui Seiki, from its inception until
today, “the ultimate in precision” has continued to be
our central focus, our reason for existence. That will
remain at our core for years to come.
