New Jones & Shipman Straight-Plunge Grinder Cowan Precision Grinding is pleased to announce the acquisition of a new Jones & Shipman Suprema Straight-Plunge Grinder. This advanced machine has a 5.0” diameter diamond roll form dressing capability, custom wheel profiling, a lateral locator, constant wheel speed, glass scales, coolant filtration and chilling, and sizing gage accuracy of .00001” (ten millionths of an inch). The diamond roll technique used on this machine produces much less heat during the grinding process, minimizing cracking and material distortion and delivering a better, more reliable product. Our new J&S straight-plunge grinder is perfect for hydraulic sleeve work. We purchased it to keep up with increasing demand for our grinding services; and to offer our customers the best possible level of quality, value and service. You can trust Cowan Precision Grinding to invest in the latest manufacturing technology to help keep you competitive in the 21st century.
