At Magnescale, in the area of high-precision measurement technologies, fundamental principles guide Magnescale to build the business by encouraging and nurturing principles of superior craftsmanship. For instance, Magnescale products, which originated from tape recorder magnetic storage technology, and boast high resistance to environmental stresses and offer exceptional precision and high resolution, have spurred progress in the machine tool industry. Meanwhile, the Laserscale products, which originated from optical disk-derived optoelectronics technologies, and were developed with electronics miniaturization in mind, have contributed to improvements in advanced semiconductor technologies and high-density production equipment.
Laserscale easily achieves measurement and control with ultra high resolution of better than 1nm. A sinusoidal wave (approximately 138nm signal pitch) is generated using the grating interference method by utilizing a holographic scale with high diffraction efficiency and a high resolution head. The BS series offers strong resistance to disturbance by air pressure or current, and is easy to install. Signal distortion, in principle, remains minimal at a high S/N ratio. Resolution of 17pm can be achieved using our automatic compensation interpolator.
Magnescale employs the magnetic detection principle, thus far less affected by the condensation or oil problems inherent in machine tools and making stable and high precision operation possible in severe environments.
Magnescale primarily uses ferrous members as the housing material to protect the detector section, thereby realizing the high vibration resistance and impact resistance characteristics. In the SR80 series, furthermore, it employs multi-point fixation construction in addition to the housing with high rigidity, achieving the industry’s top class vibration resistance and impact resistance.
