About this file
This Bill of Materials details the procurement requirements for two CNC machining tools for Oak Ridge National Laboratory (ORNL): a CNC Surface Grinder and a CNC ID/OD Cylindrical Grinder. The Surface Grinder specifications include a 10" wheel diameter, 32-98 ft/min longitudinal feed rate, 500-5000 rpm spindle speed, 2-axis NC control, and additional features such as a glass scale position system, coolant system, CNC profile wheel dresser, and multiple chuck types (magnetic, vacuum). The Cylindrical Grinder requires a hydraulic drive, ball screw traverse, internal grinding attachment, X-axis scale, and includes 3-point steady rest, 3 and 4 jaw chucks, and wheel forming capabilities. Both machines require NRTL Certification and comprehensive engineer, operator, and maintenance level training for two people. The document provides detailed machine footprint and capability specifications, with precise measurements for travel, increments, and operational ranges.
