摘要
A cylindrical grinding process suitable for frequent series changes in the Three Gorges Reservoir area can obtain CM gt= 67 and CMK gt= When RA max = 0.15 μ m, it is 1.3;RPK max = 0.25 μ m;Maximum RVK = 0.30 μ M;The maximum rdq is 5.5 degrees,The utility model is characterized in that: the workpiece (a) to be formed is fixed on the expandable mandrel centering diagram (b) type inner flange in the workpiece (a),A fixed distance from the end of the spindle (c) to the outermost throat surface (d) of the workpiece,No more than 20 mm, - the depth of grinding wheel passing (E) shall not exceed 4 microns per revolution, - the cutting determined according to the principle of making multiple grooves, the throat near the spindle (f) shall be machined first, and then the throat far away from the spindle (g) shall be manufactured, -According to the following conditions: the rotation speed of the grinding wheel is 1800 rpm, the rotation speed of the workpiece is 200 rpm, the spalling angle of the grinding wheel is 0.15?, - Three-point lubrication system (h, H ',H'）。
