David A. Simpson P.E., in Practical Onshore Gas Field Engineering, 2017 2.2.3.1 Rotating from surface. For many decades, all drilling was done by rotary table rigs. Top-drive rigs are becoming more popular as materials capability improves because it allows fewer threaded connections to be made up each step (e.g., each joint of drill pipe in a "single" drilling rig).

The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.
