Shigiya (USA) Ltd. introduces its GPES-30 series of CNC eccentric pin/polygon grinders. The grinder’s process of grinding two different eccentric areas within the same chucking eliminates or reduces setup time. Journal grinding and face grinding options are available. A polygon grinding method also eliminates or reduces training and adjusting, the company says. Plunge, oscillation and traverse grinding are also available.
           
For smooth and stable movement, the GPES-30 features closed hydrostatic slideways for the wheelhead feed, which automatically adjust to maintain the position of the wheelhead. As a result, eccentric grinding can be performed to an accuracy of less than 1 micron.
           
A high-speed, non-circular wedge-type hydrodynamic spindle bearing further contributes to high accuracy and high efficiency grinding. The direct drive spindle features a high precision angular contact bearing with no backlash on movement. Located behind the workhead, the rotary diamond dresser’s spindle is supported by an ultra precise angular contact bearing and lubricated with Microfog. An AE sensor and wheel flatness sensor are also included as standard. The tailstock is mounted with a large-diameter spindle to further ensure high precision heavy grinding, the company says.
