2. Spindle (tool) - Wikipedia

   en.wikipedia.org/wiki/Spindle_(tool)

   In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it (chuck, etc.).

3. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   Vertical milling machine. 1: milling cutter 2: spindle 3: top slide or overarm 4: column 5: table 6: Y-axis slide 7: knee 8: base. In the vertical milling machine the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. The spindle can generally be lowered (or the table can be raised, giving the ...

4. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Milling cutter in a milling machine; Router bit in a wood router; Shaper cutter or knife in a wood shaper or spindle moulder; Grinding wheel on a grinding machine. Excessive spindle speed will cause premature tool wear, breakages, and can cause tool chatter, all of which can lead to potentially dangerous conditions.

5. Drawbar (machine tool) - Wikipedia

   en.wikipedia.org/wiki/Drawbar_(machine_tool)

   The drawbar pull is an important component that allows the milling machine to keep the tool in place while it’s being used. The force from the drawbar pull supplied to the tool has to be just right because not enough force would cause the tool to wobble leading to inaccuracy, and too much force would apply excessive stress, leading to shorter tool life.

6. Machine taper - Wikipedia

   en.wikipedia.org/wiki/Machine_taper

   The patent also used the keys and slots and a tail on the tool shank to prevent the tool shank from falling out of a horizontal mill's spindle while the operator connected the drawbar. [12] ANSI B5.18-1972 specifies some essential dimensions for milling machine spindles and tool shanks using taper sizes 30, 40, 45, 50, 60. [13]

7. Surface feet per minute - Wikipedia

   en.wikipedia.org/wiki/Surface_feet_per_minute

   SFM is a combination of diameter and the velocity 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 m/s, is the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.

8. Jig grinder - Wikipedia

   en.wikipedia.org/wiki/Jig_grinder

   The machine head has two vertical travels, one for rough head adjustment and the other for precise spindle adjustment. To change the diameter of the hole to be ground, the air spindle can be offset from the axis of the rotary head by a slide in a similar manner to a boring head for a milling machine, allowing a hole of any size to be ground ...

9. CNC router - Wikipedia

   en.wikipedia.org/wiki/CNC_router

   CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle moulder, and the boring machine. They can also cut joinery such as mortises and tenons. A CNC router is very similar in concept to a CNC milling machine. Instead of routing by hand, tool paths are controlled via computer numerical control.
