A variety of variations are available to suit the size and shape of the workpiece. One of the top Centerless grinder in this business with "Laser sizing", "Discharge truing" and "Automatic transfer" are available as options for high efficiency.
Please select from the following options: wheel size and outside diameter of the workpiece.
Ultra-high speed measurement of all ground workpieces (4800 scans per second). Feedback grinding conditions to the centerless grinder in response to dimensional changes (automatic grinding condition change). Display of quality report "X-R Control Chart", "Process Capability Chart" and "Frequency Distribution Chart".
the metal-bonded wheel on the machine. High efficiency by shortening the truing time and improving the dress interval.
Centerless grinder with high productivity that grinds cylindrical processed products without supporting them with a chuck or at the center. There are In-feed grinding and Through-feed grinding methods, which contribute to the grinding of industrial parts globally such as automobiles, home appliances,medical and industrial. Koyo's Centerless grinders have the largest share in Japan.
Surface Grinder
Double disc surface grinders (KVD and HD Series) that finish up efficiently with simultaneous grinding on both sides. Super-abrasive single disc suface grinders (R Series) achieve a quality close to the grinding accuracy of lapping machines.
Diverse variations are available to suit the workpiece. One of the top Single disc surface grinder in this business with "Discharge truing" and "Automatic transfer" are available as options for high efficiency.

High precision, High speed grinding and Small footprint bearing Internal grinder. Depending on the machining specifications, the workhead can be selected from"Two rollers-one shoe type or Two-shoe magnet chuck type".
Shoe type centerless grinder that provides the high-precision and high-speed grinding required for bearing outer diameter grinding. The lineup of models from very small to large diameter parts.
Outer groove grinder for vane pump rotors. High-speed grinding with a CBN wheel. High precision groove indexing with direct connection to servo motor. Loading is installed as standard in the machine.
Outer groove grinder for vane pump rotors. High-speed grinding with a CBN wheel. High precision groove indexing with direct connection to servo motor. Loading is installed as standard in the machine.
Modular of grinding units. "Multi-surface continuous grinding line" by connecting VGF300 of different grinding unit. Equipped with a wire transfer robot as standard.
New VGF series is now available in the model for large workpieces (Max.φ400).
A newly developed special chuck enables horizontal transfer immediately after grinding. reducing loading time by 35%. Also increased machine rigidity reduces grinding time by 28% compared to conventional models.
Grinding of angle, inner surface, and spline groove of CVT movable pulley with one chuck. We have a lineup of grinding machines that divide the process, and we are one of the leading companies in the industry.
Three processes in a production line (Lapping→Obverse Side Grinding →Reverse Side Grinding) are integrated into one machine. Both sides are simultaneously ground for each wafer and allows to store and traceability of grinding data for each wafer. Cassette transfer can be handled by OHT.Double Disc Wafer Grinder that can be replcaced from the lapping machine.
Grinding a wafer one by one.Traceability to grinding data for each piece is possible. High-precision mirror surface grinder that can be replaced from the lapping machine.
