  2. Speeds and feeds - Wikipedia

    en.wikipedia.org/wiki/Speeds_and_feeds

    The spindle speed is the rotational frequency of the spindle of the machine, measured in revolutions per minute (RPM). The preferred speed is determined by working backward from the desired surface speed (sfm or m/min) and incorporating the diameter (of workpiece or cutter). The spindle may hold the: Material (as in a Lathe chuck) Drill bit in ...

  3. Annular cutter - Wikipedia

    en.wikipedia.org/wiki/Annular_cutter

    A tungsten carbide tipped (TCT) and high-speed steel (HSS) annular cutter (also known as a "core drill" or "hole saw"). An annular cutter (also called a core drill, core cutter, broach cutter, trepanning drill, hole saw, or cup-type cutter) is a form of core drill used to create holes in metal.

  4. Surface feet per minute - Wikipedia

    en.wikipedia.org/wiki/Surface_feet_per_minute

    It relates to spindle speed via variables such as cutter diameter (for rotating cutters) or workpiece diameter (for lathe work). SFM is a combination of diameter and the velocity ( RPM ) of the material measured in feet-per-minute as the spindle of a milling machine or lathe . 1 SFM equals 0.00508 surface meter per second (meter per second, or ...

  5. Drilling - Wikipedia

    en.wikipedia.org/wiki/Drilling

    Titanium drilling. Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.

  6. Tool wear - Wikipedia

    en.wikipedia.org/wiki/Tool_wear

    It occurs most frequently on softer metals, with a lower melting point. It can be prevented by increasing cutting speeds and using lubricant. When drilling it can be noticed as alternating dark and shiny rings. glazing occurs on grinding wheels, and occurs when the exposed abrasive becomes dulled. It is noticeable as a shine while the wheel is ...

  7. Drill bit - Wikipedia

    en.wikipedia.org/wiki/Drill_bit

    While the above is a common use of center drill bits, it is a technically incorrect practice and should not be considered for production use. The correct tool to start a traditionally drilled hole (a hole drilled by a high-speed steel (HSS) twist drill bit) is a spotting drill bit (or a spot drill bit, as they are referenced in the U.S.). The ...

  9. Gun drill - Wikipedia

    en.wikipedia.org/wiki/Gun_drill

    Speed of drilling depends on the material being drilled, rotational speed, and the drill diameter; a high speed drill can cut a hole in P20 steel at 75 centimeter (30 inches) per minute. Gun drilling can be done on several kinds of machine tools. On lathes, it is generally practical with hole depths of less than 50 centimeters. There are also ...
