Historical background of HASEGAWA

Wataru Hasegawa, founder of HASEGAWA, yearning for his father (a Naval Forces Arsenal Chief Engineer who died in his infancy), and dreamed of becoming a distinguished machine engineer like his father. Finally, he became a machine engineer and next desired to create his own designed machine tools.

After the business was initiated in Sugamo, Toshima-ku, Tokyo, in May, 1928, we manufactured small lathes and successfully increased the business and established a new factory in Ikebukuro in 1934. In those days many machine tool companies manufactured medium to large machine tools. However we continued to manufacture only small lathes because of the belief that a small lathe must be essential for precision processing of small parts.

The business was restarted in Itabashi Ward, Tokyo after WWII. During economic reconstruction, many orders came from the optical industries because they produced state-of-the-art precision parts with accuracy equivalent to watch parts. Requests for high precision small lathes arrived.

Since we offered greatly needed machine tools, company's business sudden increased. We established a new factory in Omiya City, Saitama Prefecture, which is presently our headquarters.

When the high economic growth period came, we began the development and manufacturing of small lathes and milling machines that applied basic technologies, and we proposed processing methods, etc. for improving production efficiency. The vertical/lateral complex milling machine and threading machine were developed in this period.

Later although the NC lathe became common and their mechanism became standardized, we maintained the development of unique machines applying technologies we had accumulated over the years. In 2000, the micro precision NC lathe "P15" was born, with dimensions reduced to 1/3 of the conventional lathe.

In recent years, we maintain steady export results not only Asia but also Europe and America owing to increasing manufacturing globalization. This successful sales result depends on overseas sales routes established at the high economic growth period. So we can promptly correspond to overseas needs.

WHŒ^28‰Dù”Ձiº˜a‰Šúj

Model-WH, 28 Inch Lathe (about 1930)

This is typical of our early, small lathes. We manufactured small lathes with cast metal stands for precision processing although desk-top type small lathes were common at that time.

WHNƒVƒŠ[ƒY ”Ä—pù”Ձiº˜a38”N`j

WHN Series, General-purpose Lathe (Since 1963 to present)

This is a small, general-purpose lathe that was largely modeled on the conventional WH type. This is the basis of a lot of improved models like the rack type HF model and the threading HL model. It is a very valuable domestically manufactured lathe that has kept selling since 1963 with just minor changes.

HPF Series, General-purpose Milling Machine (Since 1961 to present)

This is a small complex milling machine having advantages of compactness and easy handling incorporating vertical and lateral milling machine merits. This model has a lot of functions for small lot manufacturing of small parts has kept selling. This model has kept selling with just minor changes.

HL Series, Threading Machine (1963 to 1990)

This is known as the revolutionary threading machine that overturned common ideas on thread processing mechanisms. This lathe is equipped with rotary threading system which turns the bit at high speed. Until the NC lathe became popular, this machine was in demand for large lot precision screw production.

FL Series, Complex Automatic Milling machine (1974 to 1995)

This is the complex milling machine with column customized by the block build method and incorporating lathe guide surface technology. It suits various processing methods and can supplement an effective production system.

HT-20, Precision NC Lathe (1986 to 1994)

This is a basic small precision NC lathe J24 with high cost efficiency. It has high grade machine performance. Its construction is faithful to our basic philosophy so it has sufficient rigidity and long term stability.

HMC-V2, Machining Center (1990 to 2000)

This is an epoch-making small precision machining center that achieves a 1.0 second ATC bit replacement time. Its height manufacturing efficiency has earned a reputation in the world not only domestic ally.

Wup-50, Dual Spindle NC Turret lathe (Since 1992 to present)

This is a NC one turret lathe with dual spindle having built-in loader to loading time to zero. Systems that can minimize non-processing time largely influence the automatic production line setup.

P15 ’´¬Œ^¸–§NCù”Ձi•½¬12”N`j

P15 Micro Precision NC Lathe (Since 2000 to present)

This compact and operator-less NC precision lathe raises expectations for improved automatic line setups because it easily replaces a old machines when a current automatic or manual production line is upgraded or automated.
