Seiko is a world-famous high-tech group originating from Japan. The group's main businesses include high-precision watches, high-precision grinding machines, high-precision spindles, etc. SII (Seiko Instruments) is the enterprise within the Seiko group that professionally develops and produces high-precision internal grinding machines and high-precision grinding motorized spindles. SII was founded in 1937; Seiko Instruments was established in 1964; in 1966 it developed high-precision grinding machines and high-frequency internal grinding motorized spindles; and since 2013 it has been selling motorized spindle products independently.
Our high-speed high-precision motorized spindles are available in two series: SSPG (high speed) and MH (ultra-high speed), with speeds of 30,000rpm, 42,000rpm, 45,000rpm, 60,000rpm, 75,000rpm, 80,000rpm, 90,000rpm, 110,000rpm, 150,000rpm, 180,000rpm, 200,000rpm, etc.
Compared with other spindle manufacturers, we have incomparable advantages in the high-speed internal grinding industry! For example, we have nearly 60 years of internal grinding application experience and are familiar with all the technical processes and key points of internal grinding machine design, machining, operation and maintenance. All our purchased components are world top brands (the stators and rotors are Swiss e+a). All our internal grinding motorized spindles, including the 200,000rpm models, use high-speed ceramic ball bearings, which ensure rigidity while maintaining precision. Moreover, our bearings are high-precision, long-life bearings specially made by NTN. At present, the performance indicators of our internal grinding motorized spindles have surpassed international industry standards: for example, our spindle nose precision is 1um (industry standard 2um), and the spindle vibration value does not exceed 0.5mm/s (industry standard 1mm/s).
At present, more than 1,000 high-speed high-precision internal grinding motorized spindles are sold to all parts of the world every year, and they are well received by high-precision grinding machine manufacturers and users!
