A drill press Drill press (then called a boring machine) boring wooden reels for winding barbed wire, 1917. A drill press (also known as a pedestal drill, pillar drill, or bench drill) is a style of drill that may be mounted on a stand or bolted to the floor or workbench. Portable models are made, some including a magnetic base.
Tools affected include tipped tools, tool bits, and drill bits that are used with machine tools. Types of wear include: flank wear in which the portion of the tool in contact with the finished part erodes. Can be described using the Tool Life Expectancy equation. crater wear in which contact with chips erodes the rake face. This is somewhat ...
Machine tapers for tool holding included Morse tapers (on early models) and the R8 taper (a widely used standard that Bridgeport created) on most models. Both Morse and R8 allowed for both collets and solid holders, and a drill chuck could be held by either of the latter. Currently R8 and Erickson #30 Quick Change tool holders are available.
Slips is a device used to grip and hold the upper part of a drill string to the drill floor on an oil rig. [1] The slips are constructed as a collection of metal wedges, hinged together to form a circular shape around the drill pipe. On the inside surface, the slips normally has replaceable steel teeth that grips the pipe.
A third type also exists, a lighter, more versatile machine, called a mill-drill. The mill-drill is a close relative of the vertical mill and quite popular in light industry; and with hobbyists. A mill-drill is similar in basic configuration to a very heavy drill press, but equipped with an X-Y table and a much larger column.
Drill string connections are made or broken on the drill floor, and the driller's console for controlling the major components of the rig are located there. Attached to the rig floor is a small metal room, the doghouse, where the rig crew can meet, take breaks, and take refuge from the elements during idle times. Drill floor with the drill pipe
