Embodiment Construction
[0020] The present invention will be further described below in conjunction with embodiment.
[0021] The embodiment of the present invention selects the bottom plane of the finely ground broach as the test. The material of the broach is W10Mo4Cr4V3Al, and its material hardness is HRC66-67. The experiment selects an M7120A surface grinder, the grinding fluid is an extreme pressure emulsion, and the selection specification of the grinding wheel is 1A1 / Cubic boron nitride grinding wheel of model T2250X10X75X10X3CBN100 / 120B100.
[0022] The grinding speed is 18.5m / s;
[0023] Back cutting amount is 0.005mm;
[0024] The speed of the workpiece is 16m / min;
[0025] The axial feed speed is 0.6m / min.
[0026] During the grinding process, the temperature of the workpiece and the grinding wheel is low, and the extreme pressure emulsion forms an adsorption film under the high temperature and high pressure during cutting, which acts as a lubricant; so that the workpiece has a high su...
