Guide to CNC Machining Tolerances | Fractory
The tolerance limit defines the maximum allowable difference between corresponding dimensions of the two parts. For CNC machining, the standard tolerance limit is set around +/-.005" (0.127 mm). For reference, the thickness of a human hair is 0.002" (0.05 mm).
Studer Machine uses lasers to measure grinding process ...
Grinding jobs requires strict tolerances. On grinding machines, the tolerances for the dimensions, form and position of finishing processes run tight, and in many cases, shops check these specifications against hard data. Part processing time increases if operators must move parts to and from external equipment to measure them and make corrections.

±0.001mm Ultra Precision Grinding Services Company - DEK
When parts require grinding with tolerances of up to ±0.001mm (+/-0.00005 inch), even small variations in the environment can alter the grinding process and measurements. Maintaining a temperature of 68° Fahrenheit (20° Celsius) ensures all grinding is consistent and that the measurements are accurate.

Engineering:Grinding machine - HandWiki
Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns.
Typical Tolerances of Manufacturing Processes
Typical Tolerances of Manufacturing Processes . In the past, one of the traditional weaknesses with graduating mechanical design engineers is their inability to select tolerances. Most students were reasonably proficient using one or more CAD packages and could produce drawings which were pretty good (given their limited experience levels).

CNC machines produce very accurate workpieces, and they do so repeatedly for two or even 2,000 workpieces. Dimensional tolerances between ±0.002 and 0.005 inch (50 to 127 microns) are easy to achieve initially and hold throughout a cutting tool's life. Tolerances between ±0.001 and 0.002 inch (25 to 50 microns) are still easy to achieve.
