On September 30th, 2024, Seibu’s Precision Machine Division ﬁ nished construction on a
major facility expansion to meet the growing global demand for Seibu Wire EDM machines.
In the 2010s, demand for Seibu machines began to push the production limit of 60
machines per month, and Seibu management began discussing the need for expanded
manufacturing capabilities. By 2019, production had been running at maximum capacity,
and a second factory was completed, which increased capacity to 80 machines per

month. It, too, was quickly running at full capacity.

In the fall of 2021, Seibu planned, and decided to invest in additional capacity to increase output capability
to 120 machines per month. In December 2022, construction began on a new state-of-the-art facility that
combines manufacturing space with quality control and a showroom for conducting test cuts. The new
facility is three stories tall and has approximately 127,000 square feet of ﬂ oor space.

The new facility has multiple
assembly bays with overhead
cranes to facilitate the movement

of the machines through the
production cycle. The building
includes a sophisticated air
management system with air
intake grills and ﬁ lters located at
numerous positions around the
bays. This system ensures that the
air at all positions in the bay is at
a constant controlled temperature
and that it is clean of dust and
particulates that could adversely One of Se
