	Grinding machine - Wikipedia, the free encyclopedia
		A grinding machine is a machine tool used for producing very fine finishes or making very light cuts, using an abrasive wheel as the cutting device.
		Very fine control of the grinding head or tables position is possible using a vernier calibrated hand wheel, or using the features of NC or CNC controls.
		Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance.

	Grinding machine - Patent 4123878
		A grinding machine in which sparkout grinding is carried out for a period of time that is selected from workpiece to workpiece by a power meter means which terminates grinding when the power consumed by the wheel reaches a predetermined value, which value is varied from new wheel conditions to worn wheel conditions.
		A grinding machine is recited in claim 3, wherein means is provided to terminate the finish grind at a given point in wheelhead cross-feed, the length of the sparkout being determined soley by the power meter and its switch.
		In general, the invention consists of a grinding machine for internal grinding, the machine having a base on which are mounted a wheelhead for carrying a rotatable abrasive wheel and a workhead for carrying a workpiece having a bore to be finished.

	Grinding machine - Patent 5971836
		A grinding machine according to claim 12; wherein the contact position detection means detects the contact position by measuring an angular position of the workpiece and a position of the grinding wheel during reciprocation thereof.
		A grinding machine according to claim 23; wherein during grinding of the workpiece, a center of the grinding member in the thickness direction thereof is shifted from the second rotational axis by a distance equal to less than half of the thickness of the grinding member.
		The grinding machine, generally indicated by reference numeral 1, comprises a rotational member or main spindle 4 for rotating a disklike workpiece 3 about a rotational axis B and a headstock 5 to which the spindle 4 is fixedly attached.

	Grinding Machine
		I first built a machine for grinding and figuring mirrors according to the directions in the Sky and Telescope article by Tom Waineo.(1) There are directions for a Waineo machine available on the web.(2) The machine worked, but it was gutless and took a very long time to polish out a 6" blank.
		I gradually became frustrated with two limitations of this machine: the table rocked, and the stroke length was not continuously adjustable.
		The blank is centered by taping a clear ruler to a fixed part of the machine and watching for wobble in the blank when the table is rotated.

	Raymond mill\|Raymond Grinder\|grinding machine--LIMING ROAD & BRIDGE
		The machine is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceram and slag below scale 7 of Moth’s hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy for power generation and processing.
		After being grinded, the stuff is to be routed to the sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding.
		In the grinding chamber, since the stuff may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases.
