Mitsui High-tec, Inc. designs its machines using state-of-the-art technology and precision engineering. They have a team of experienced engineers who use advanced computer-aided design (CAD) software to create detailed blueprints of the machines.
The machines are then built using high-quality materials and cutting-edge manufacturing techniques, such as CNC machining and robotic welding.
The company also uses advanced testing and quality control methods to ensure that the machines meet or exceed industry standards. This allows them to produce machines that are not only efficient and reliable but also precise and accurate.
Mirror Finishing
The surface grinder from Mitsui has a smooth operating ball guiding system. It is commonly believed that a ball guide system's lack of stiffness makes it unsuitable for mirror finishing. However, the mirror surface produced by our effort to make component parts more rigid and accurate is comparable to that produced by other guiding systems.
More than 1.6 million sets of motor cores for automotive applications are provided annually by Mitsui High-tec, Inc. with high-precision interlock technology that has been developed over a long period of time.
Construction
Mitsui's meahanite castings are extremely heavy and reinforced with internal ribs. They feature a 5-point leveling system using jack bolts and plates, and are designed with the Mitsui trademark of easy component removal and replacement for minimal maintenance and downtime cost.
Precision
The precision of our Mitsui surface grinders is evident in the top-of-the-line cartridge spindle that can be easily removed. Our grinders also feature a carriage and saddle that moves on two 45-degree V-ways and a table that moves on linear ball bearings, resulting in the repeatability that Mitsui is known for. There are no compromises in the design.
Durability
Precision design is essential, but it is also crucial that it can be maintained over time. Mitsui ensures durability by using D-2 hardened and ground steel ways on the table, carriage, saddle, and column for vertical movement. Linear ball bearings also add to the durability of the table and carriage union. The cartridge spindle's lubrication is also sealed for life and protected from dust. The standard automatic lubricating system automatically lubricates all vital components to minimize wear and friction, leaving you one less task to worry about.

General Information
About Mitsui High-Tec Inc.
Mitsui High-tec, Inc. was founded in 1949 by Yoshiaki Mitsui, who was born in Kumamoto Prefecture in 1921 and passed away in 2008. He was the founder of Mitsui MFG. CO., LTD, which later became Mitsui High-tec, Inc. He was continuously involved in the development of stamping tools and responsible for driving the transition from hand-finished technology to post-heat treatment and full-grinding finishing. He received the Japanese Emperor's Indigo Ribbon in 1984.
The leadership of Mitsui's tenaciously challenging spirit achieved industry paradigm shifts for technology of high precision tungsten carbide tools, IC leadframe stamping tools, MAC system (Mitsui Automatic Core assembly system), and spot electroplating production equipment. Also, aggressive erection of factories overseas contributed to early successes.
In the short span of a single generation, Mitsui High-tec has become a truly global leading-edge technology corporation. The corporate motto is "Roads open up for those who travel a noble path" and the employees are constantly asked, "What is the truth?" This simple spirit embodied by the Corporate Motto guides the corporation.
