Scraping & Lapping Technology
Reference standard devices and key machine components, such as high-precision surface plates and square gauges that have undergone scraping and lapping by skilled heat-treatment technicians, are vital to high-precision machines.
High Precision V-V Roller Guide Way with Non-Circular System
The V-V roller guide way with a non-circular system, configured with strictly selected high-precision needles, minimizes friction. Slight undulation is kept under 20 nm, and high positioning accuracy is combined with accurate motion performance. On the vertical axis, preload is applied aero statically. This is a core technology supporting the high speed, high precision, and high rigidity required as basic functions of high-precision machines.
High Precision Aerostatic Bearing Spindle
The combination of aerostatic bearings and a high-performance electric motor realizes both high precision and high-speed performance, along with long service life. It supports high-precision machining and high-speed machining as an energy-saving main unit. It is also sold separately as a spindle unit.
Linear Motor Drive Technology
The coreless linear motor and the linear motor with cores have both been successfully commercialized. Our proprietary technology has enabled the cored linear motor drive system to achieve high precision and high responsiveness, with strong stability against disturbance factors.
High-Speed / High-Precision Control Technology and Linear Motor Drive Technology
These technologies have enabled world-leading 1 nm-scale feedback control. In addition, they establish high-gain, high-precision drive technology for core-type linear motors, enabling stable cutting and grinding processes as well as high form accuracy and surface accuracy.
High-Precision Roller Bearing Rotary Table
This rotary table is supported by a rigid, highly precise roller bearing. It performs well under unbalanced loads and achieves high precision comparable to that of an aerostatic bearing table.
High-Precision Table-Type Aerostatic Bearing Spindle
This turning and indexing table is supported by aerostatic bearings. It is a long-life spindle designed for use in high-precision machines for high-precision machining. It can also be used as an attachment for a wide variety of operations, such as high-precision parts machining and measurement.
High-Precision Aerostatic Bearing Guideway
This linear guideway is supported by aerostatic bearings and provides high motion performance. In addition to its low friction coefficient and long service life, it has no direct contact between moving parts, preventing abrasion powder and helping maintain a clean operating environment. Compared with other bearing systems, its stiffness and load capacity are relatively low, so it is used in machines and measuring equipment where load fluctuation is minimal.
High-Precision V-V Slide Bearing Guideway
Thanks to advanced scraping techniques and a durable machine structure, this linear guideway system is ideal in terms of precision, stiffness, movement, and stability. It is an essential core technology for high-precision machine tools, measuring equipment, and related applications.
