Design and manufacture of HDD production equipment
Each process of the job is dispatched to most competitive group company
We think that all group companies are one team. We break the job to several processes and dispatch each process to each company who is most competitive on that process. The process of design, our competitiveness is the know-how on the first look VA and the necessary redundancy. The process of procurement, each area has specific competitive category of the parts. The process of assembly and support, both processes will be performed by one company.

Original standard part
Center compliance unit
We sale the unit as a standard part
The pick and place of parts requires centering of the grasp mechanism. This unit enables the grasp mechanism to center automatically using minute strength during pick and place, and locks during motion. The unit is used in our company’s precision automation tools.
Self-controlled roller conveyor
The feature is to input control data easily
The conveyor controls itself by own CPU. No PLC control is required. The conveyor can be used for the high precision assembly like HDD assembly.
