By the rotation of hand-wheel, the spindle moves up and down in the vertical direction in order to give the necessary amount of feed to the work. Here, the rotational motion is converted into linear motion by means of a Rack and Pinion mechanism which was explained below. 6.Chuck: It is used to hold the drill bit.
A dial indicator attached to the spindle for precise mill head alignment. A vertical mill's head is able to tilt from front to back and side to side. Occasionally these adjustments can drift. The mill head should be checked and adjusted periodically, ensuring that the spindle is perpendicular to the table. Remove the vice from the milling table.
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).

Help with Lagun Vertical Mill. I just purchased a used 9 x 49 Lagun Vertical mill and can't seem to get it in low gear. The handle will take it out of high gear into neutral, but that's it (the handle just keeps turning without ever latching into low). The head runs fine, but I think I'm going to have to take it apart to see what's wrong.
The T-35 mates this rotary table to an A-axis pivot that feeds the spindle head from 30 degrees above horizontal to 30 degrees below. The enclosed machine offers a workzone 50 inches in diameter by 50 inches high. The ideal part for this machine, says Mr. Kramer, is a cylinder with holes around its periphery—particularly angled holes.
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
