An ideal entry-level model, Shigiya (USA) Ltd.’s all-new GPS-30B CNC cylindrical grinder offers high-quality performance at an affordable price.

For exceptional accuracy and ease of operation, the GPS-30B is built with Shigiya’s proven and cutting-edge technology. A streamlined machine design using common parts and an efficient machine manufacturing process reduce costs and increase affordability.

The GPS-30B boasts a range of high-quality and rigid features to allow for heavy and precise grinding. In fact, Shigiya developed its own bearing grinder to grind the GPS-30B’s non-concentric hydrodynamic bearings to ensure their rigidity and precision.

GPS-30B wheelhead and table head sliding surfaces have wide V and flat slide ways that provide sufficient rigidity and load capacity. The high damping performance and equalization of the lubrication oil provided by the oil film’s squeezing effect help the grinder to maintain precision and smooth operation for decades. To prevent thermal displacement due to an increase in lubrication temperature, the wheel spindle oil is stored in an isolated tank. Because the wheel dressing device is mounted onto the lower table of the GPS-30B, there is no need to change dressing coordinates. A non-swivel wheel head with a highly rigid main body and large-diameter wheel spindle is available as an option.

For added convenience, Shigiya’s exclusive interactive conversational programming system requires virtually no programming knowledge to operate. The system automatically sets up optimum grinding patterns and conditions after an operator enters numeric figures for three items. The system accommodates a wide variety of grinding and dressing patterns to facilitate high-precision cylindrical grinding.

The GPS-30 features a 300-mm diameter swing over table, maximum grinding diameter of 300 mm and 500- to 2,000-mm distance between centers. Models with up to 750-mm center distance come equipped with a compact workhead and tailstock units.
