Hawking VS Polishing P32
Item	Hawking tech	Polishing
result	reach super mirror-finishing result of Ra≤0.2µm ; feeding between 50 and 80m/min	Ra1.6-0.8µm
efficience	line speed between 50 and 80m/min; feeding between 0.2 and 0.5 mm/r. efficient as the semi-superfinishing	inefficient
microhardness	improve 20% more than before	no change
fatigue	improve	no change
stress situation on metal surface	eliminate pulling stress on metal surface and preset perfect pressing stress	uncertainty
wear-resisting	improve	no change
corrosion resisting	improve	no change
quality on metal surface	even	uneven because of constant abrasing by grinding wheel
other materials consumption	no	using polishing whee,grinding material, abrasive belt etc.
procedure	not need moving the workpiece..Just clamp our equipment on the same lathe /machine tool	must move a workpiece to a polishing machine
operating envirenment	energy-efficient,enviroment protection,no sand & scrap iron	will leave some sand,scrap iron,dust , bad enviroment
suitability	best suitability,suitable for all kinds of surface shape	bad suitability, curved surface can not be processed
damage to a lathe/machine tool	no cutting and no damage to a lathe	sands left over can damage the part of rail road on the lathe
operating room	need a little space to set our equipment	special operating room, spcial space
possibility of danger	no	grinding wheel might damage an operator

Steps of Hawking VS Normal grinding
Step	Hawking tech	Normal grinding
1	use a suitable cutter imported from Switzerland to get a basic size and geometrical tolerance meeting the requirement of drawing. Roughness is Ra2.1µm.	use a Kenner KT315 cutter to get a basic size and geometrical tolerance meeting the requirement of drawing by finish maching. Roughness is between Ra3.2 and 6.3µm.
2	use a Hawking cutter clamped on the lathe to process (line speed of processing is 39 m/min, feeding is 0.3mm/r)	it will take72 hoursto manually grind a work piece by using a millstone with No.150 diamond grain. In order to completely eliminate the screwing wave during grinding.
3	done intwo daysfrom size precision to mirror finishing level.Value of Ra between 0.07 and 0.1µm	it will take24 hoursto semi-grind a work piece by using a millstone with No.180 diamond grain.
4	better than what the design requires	it will take16 hoursto grind a work piece by using a millstone with No.240 diamond grain.
5		it will take3 hoursto polish a work piece by using W7 polishing paste and kerosene on lathe when the top spinning speed is 40r/min and line speed about 300m/min .
6		roughness between Ra0.16 and 0.2µm,meet the requirement
