2. Jig grinder - Wikipedia

   en.wikipedia.org/wiki/Jig_grinder

   The machine operates by a high-speed air spindle rotating a grinding bit. The air spindles are removable and interchangeable to achieve varying surface speeds. Some spindles are fixed speed (such as at 60,000 rpm), others are adjustable (such as from 30,000 to 50,000 rpm), and still others are very high speed (such as at 175,000 rpm).

3. Spindle (tool) - Wikipedia

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

   A main component of this spindle is the motor, stored internally. Internal Motor: limited power and torque due to restricted space within the spindle housing; Speed Range: 20,000 [3]-60,000 RPM [2] (top speed according to design) Advantage: high top speed expands application use; Disadvantage: sensitive life range according to use

4. Grinding (abrasive cutting) - Wikipedia

   en.wikipedia.org/wiki/Grinding_(abrasive_cutting)

   Precision grinding would take more than 200 s to do the same. CFG has the disadvantage of a wheel that is constantly degrading, requires high spindle power (51 hp or 38 kW), and is limited in the length of part it can machine. [1] To address the problem of wheel sharpness, continuous-dress creep-feed grinding (CDCF) was developed in 1970s. The ...

5. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

6. Milling (machining) - Wikipedia

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

   This may be done by varying directions [2] on one or several axes, cutter head speed, and pressure. [3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise ...

7. Lathe - Wikipedia

   en.wikipedia.org/wiki/Lathe

   The headstock contains high-precision spinning bearings. Rotating within the bearings is a horizontal axle, with an axis parallel to the bed, called the spindle. Spindles are often hollow and have an interior Morse taper on the spindle nose (i.e., facing to the right / towards the bed) by which work-holding accessories may be mounted to the ...

8. Air bearing - Wikipedia

   en.wikipedia.org/wiki/Air_bearing

   Gas bearings are mainly used in precision machinery tools (measuring and processing machines) and high-speed machines (spindle, small-scale turbomachinery, precision gyroscopes). Air borne high frequency spindle with integrated feeding

9. Chuck (engineering) - Wikipedia

   en.wikipedia.org/wiki/Chuck_(engineering)

   It is simple and useful, but the degree of control of concentricity is not quite good enough to be foolproof for high-speed, high-precision work (high precision can be achieved, but the time and skill involved in the setups makes it a poor choice now that better options exist, such as the cam-lock spindle noses described below). Threaded ...
